Something to wonder about

What You Have

The Two Sided Market

When we think of investing in various macro business needs e.g. revenue. We see that establishing relationships with customers to stimulate sales is why we create the goods and services, hopefully, others want.

If the buyer has something the seller wants, in exchange for the good or service they desire, then a transaction occurs. The challenge is simple, each party defines the value of what they are providing or exchanging and presto the trade occurs.

When society grows and the complexity of what each of us produces and when our needs are not aligned to this process called barter, a means of monetization is established. Society creates a trusted form of exchange – pebbles, coins, money, a promissory note or now even cyptocurrencies.

In other words, society creates an answer to enable the exchange of goods and services between parties who do not have goods and services the other party seeks in exchange.

With cash, coins or other trangible representations of value, commerce is easy. When we complicate things and worry about carrying cash and seek to buy things with debt. A need for a Network emerges.

These payment networks, by necessity, add complexity. They create the need to establish two sides to the market, one focused on the relationship with the buyer and the other with the seller.

Issuance and Acceptance. Two words to descibe the two sides of a network. It’s only when the two sides of the market have sufficient participants. Only at the tipping point, enough critical mass exists, to create a self sustaining network. This is the network. At this moment the network blossoms. If either side of the market does not achieve critical mass, the network collapses.

Any two entities familiar and trusting in the Brand, or each other, can easily establish a temporary relationship. Adding anonymity to the requirements, increases the leave of trust and recognition the Brand must establish.

In a digital environment we have to define mechanisms to share and establish trust across trillions of electrons. The two sides will not pursue understanding of nor focus on security. Until the risk exceeds a threshold unique to each party on either side of the market.

To often in the past, the idea of the individuality of the individual or the need to design security in from the beginning. Has left us with a legacy of system all needing design of custom approaches to how to integrate security with requisites necessary to capture, calculate and manage risk.

The Artifact of Trust

When a mutually trusted set of parties gives the citizen, consumer, employee or courtier a card, a device or an object and provides every acceptor with a reader capable of recognizing the trusted thing; then the two parties are in a position to establish “trust”. The consumer has a thing which is recognized and trusted by the acceptor. This is often referred to as “What You Have”.

Once the thing is recognized by the acceptor, then, the process of identification and authorizations (the transaction) can take place. The object – the artifact – carries an identifier. It possesses characteristics that establish its unique character. The object also posesses a means of assuring the acceptor the presentation of that identifier repreents a unique entity.

The simplest artifact of establishing “trust” is a hand held thing, be it a key, fob, card, watch, pendant, phone, ear piece. It does not matter what it is, all that counts is that the merchant recognizes it and that the consumer is willing to carry and present it.

Trust, for the merchant, means they can, according to the rules, recognize and authenticate the thing. They are then in a possition to pursue a temporary and trusted relationship. What can be achieved during the time the relationship of trusted is bounded, is the constrained by an additional layer. In this layer the consumer, the acceptor and any third parties address which the rights and privileges are to be granted or pursued. This is when the exchange, sale, conversation, tranaction, event or access is granted.

Two sides meet several common mediums of exchange are available.

Digital Identity

Question for all those who advocate migration from card to electronic

We all are aware and many of us dream of a time when all of our physical identity artifacts are digital. We dream of consolidating these credentials in our electronic wallet, otherwise known as our mobile phone.

Today while visiting an outpatient imaging center, I was asked for my driver’s license. She would only accept the physical document, I offered to send an image by email. Her goal to scan my identity document into the electronic patient file she was creating. The idea of an image of the driver’s license in an email, well.

Sure the system could easily be changed to record digital credentials delivered by NFC or BLE. The first question, given the expensive medical system we have here in America; at whose cost?

Time could not be argued as a saving, she would only have saved a second or three of time to pass the card back to me.

People discuss contactless cards and contrast them to the convenience of a Mobile Wallet. What we often forget is the reality. As long as we need to carry other physical identity artifacts, the convergence of our leather wallet into our electronic device is not happening.

In my humble opinion, it is an all or nothing situation. Yes, I will add digital credentials into the mobile wallet. But, unfortunately, the leather wallet is still part of my attire.

Better still, it does not need to be recharged. My leather wallet still works after the phone’s battery has died.

Authentication or Identification

Two words Authentication and Identification.

Reading what Wikipedia had to say about authentication leads to an interesting array of discussions across a wide set of sciences and other social segments. The exploration led to a search for a definition of Identification:

  • The act of identifying, or proving to be the same.
  • The state of being identified.
  • A particular instance of identifying something.
  • A document or documents serving as evidence of a person’s identity.

Next exploring what Wikipedia had to say about Authentication leads to a much richer discussion aligned around the idea of assuring the truth of a particular attribute, someone is claiming to be true. Seeking to assure a degree of parallelism to the discussion:

Authentication is

  • something which validates or confirms the authenticity of something
  • computing proof of the identity of a userlogging on to some network

These two words: authentication and identification, some think represent the same act, yet when we bring into the conversation – privacy the two words have very different meanings.

We then have to think about the how and the what we are attempting to do.

In the physical world there are a set of situations and considerations. We will leave those for another article.

When we think about the digital world, this place were our physical presence is not present. We must find solutions that prove we are who we are without necessary needing another to vouch for our identity each time.

As a consumer we want the freedom to visit multiple sites and believe that where we visit and who we interact with is not open to all to know.

As I write, I can hear some say, all our stuff is known so why try to hide. They are correct and then they miss the concern – who knows. Not to get distracted.

Verification, a third word must enter into the discussion. In order for anything associated with only serving or sharing with a clear and identified party one needs to be able to provide Identity.

Trust – the truth of our identity

Such a big word.

This Sunday our minister spoke of Mark 5:20-43 and how we must trust in Jesus.

Her evocative sermon provoked a wider or is it broader question,

“What is Trust”.

First we must ask the classic question what does the Dictionary and Wikipedia say. This then leads us to have to think of the use of the term. Are we using it to describe a legal structure, the nature of a business, a computational concept or the name of a film, song or other human creation?

Given this discussion started as a result of a sermon, the best approach is to consider the social and emotion context of trust. Understand the sociology, psychology, philosophy, economics and systems perspective, may offer clarity to the words “we trust … “. In the first paragraph the Wikipedia authors condensed a lot of thought into a short paragraph. {formatting of my doing}.

Definitions of trust typically refer to a situation characterized by the following aspects:

  • One party is willing to rely on the actions of another party (trustee); the situation is directed to the future.
  • In addition, the abandons control over the actions performed by the trustee.
  • As a consequence, the is uncertain about the outcome of the other’s actions; they can only develop and evaluate expectations.
  • The uncertainty involves the risk of failure or harm to the trustor if the trustee will not behave as desired.

In this flow of thought it is clear this word trust carries with it risk. It assumes we are thinking of tomorrow and there is an expectation the trustee will act in a manner that is consistent with our “the trustors” wishes, hopes and desires.

Vladimir Ilych Lenin expressed this idea with the sentence “Trust is good, control is better”.

In the field I have spent the better part of my life, computers have played a big part. Be it as a tool we programmed to perform a function or task. Or, the systems supporting the products and services we sought to promote. More recently, as we look to this global village we are a member of. We think about the need to establish mechanisms to assure trust between parties. Parties who probably will never meet, in person or even by chance speak to. We must therefore establish acceptable social and psychological mechanism with machines which we inherently are wary of.

Looking to the sociology of trust set of sentences stands out

“It does not exist outside of our vision of the other. This image can be real or imaginary, but it is this one which permits the creation of the Trust.” … “Because of it, trust acts as a reductor of social complexity, allowing for actions that are otherwise too complex to be considered (or even impossible to consider at all); specifically for cooperation.”

All of this leads one to wonder how in a anonymous world can trust be established.

Trust is specifically valuable if the trustee is much more powerful than the trustor, yet the trustor is under social obligation to support the trustee.

In a social context this thought offers a view as to the dominance a position the trustee must have in society. It also frames the responsibility and the obligation established by the trustor in the trustee.

This then leads one think about Multi-Factor Authentication. MFA is emerging as the standard method companies are used to assure one of degree of “trust”. Trust in a claim of the identity of another, be it a customer, employee, citizen or recognized guest.

Is this enough? How can a company be assured of the identity of an individual? How can we, a third party, accept the claims or attributes offers when they are presenting themselves to us. Especially when they present themselves across a global digital highway, prone to the nefarious acts of those who seek to take advantage and profit.

Proof of identity therefore becomes the primary means of establishing trust in an seemingly anonymous space – Cyber Space. This need for proof of identity is the role of the Trustee. These parties who we instinctively have faith in can give us the ability to trust in the claims of identity and the associated attributes representing the characteristics, assets and relationships a person has.

For now I will stop. The next step is to think of and look at words. enrollment, proof, identification,registration, identifier, authentication, rights, privileges, claims, certificates and authority.

Why do we need Tokens and Tokenization

Recently I was directed to a link http://paymentsjournal.com/tokens-work-because/ and wanted to write the author Sarah Grotta.  As I wrote the message crystallized in my head and maybe as this prior post already discussed, this idea of tokenization made me cringe.

I contend that Tokens exist because we turned the PAN Personal  / Primary Account Number, like we turned the SSN Social Security Number, into an authenticator.  One can must ask the question.  How can a random value (an identifier) become an authenticator and remain secure?

EMV works because it renders the Card unique, hence addressing the question of counterfeit, by employing the first factor of the classic MFA Multi-Factor Authentication concept “What You Have”.  EMV defined a common set of secrets and digital credentials; securely stored in a Secure Element or Chip Card.

We here in the United States decided not to implement the second factor, the Personal Identification Number or PIN, for a variety of reasons. Hence, why Lost and Stolen remains an issue or weakness in the American Card Payment environment.

Biometrics are emerging and could solve for the assurance of cardholder presence.  The challenge is how to effectively (cost and convenience) locate the biometric sensor and facilitate the matching of the sensors output to the persons registered biometric.  Let alone, how does one make sure the right persons biometric was registered and associated with the device.

In the mail order / telephone order, now cyberspace, we did not replicate merchant authentication, the first factor – “What You Have. The card, once was secured with things like the magnetic stripe, using CVV1, the Hologram and the other physical features.  We simply shifted the liability to the merchant and called it a “card not present” transaction.

People can claim all sorts of goodness because of tokenization.  They can talk about how the EMVCo’s tokenization framework describes the use of tokens in device and domain specific scenarios.  All of this, an issuer, could have done; if they, like some did, simply issued another number, a PAN, to the wife, bracelet, watch, ring or whatever other permutation they deemed appropriate.  They can talk about dynamic data.  yet what they often forget to include when they use the words “Dynamic Data” they are really talking about a cryptographic value as described in EMVCo Book 2.

Yes, this does mean the question of how the PAN and its digital credentials get deployed; has to be addressed.  This said, GSMA with EPC did offer some thoughts, last decade, when they described the Trusted Service Manager

Instead handset oligopolies replaced the MNO with the their Mobile Pay wallets.  They working with the Payment Networks and focused on control and the creation of income.  They, as monopolist will, have created barriers, restricting others from offering comparable services.  The TSP now becomes this restrictive service that guarantees the power of companies like Apple and Google, supported by their friends, the payment network operators.

The original article also spoke of the PAR; another data element merchants, processors and the industry, will have to invest in supporting.

I ask the question.

If we had assured the authentication and verification of every payment transaction
Using Multi-Factor Authentication
Why did we need to turn the PAN into a dynamic value? 

My contention, simply use the appropriate level of  cryptography.

If the Issuer or their processor is in control and understands basic EMV and Cryptography, then securing the PAN is not an issue.

Consider household financial management.  If each member of a household has a unique PAN; budget, tax preparation and understanding who spent what where is a lot easier.  The husband,wife and children should have their own unique PAN, stored in the clear in their devices and on their card.

The real requirement, my personal devices, including my payment card, simply need to be linked to one PAN their Personal Account Number, associated with the individual.  The PAN Sequence number could easily allows each device to be uniquely identified, if necessary.  The card and devices becomes the carrier of your identifier.  A thing that can be authentication as something you have.

Here is where the second factor comes in.  Is the person presenting the PAN the rightful and authorized individual? All this required, is assurance to the shareholders that the presentment of the PAN is a unique and authorized event.  This is best achieve by using either something you know or something you are to bind the individual to the instrument carrying the Identifier.

Yes, a bit of friction to assure the  consumer they are securely paying for what they want to buy

Since the World Wide Web came of age and merchants saw its potential.  The question of how to secure the Card Not Present space, this question of cardholder presence, has not been properly addressed.  Visa and MasterCard (when they were not for profit associations) created the utility of the Card Verification Result CVV2, CID or CVC2 which would be printed on  on the card and not part of the magnetic stripe, the problem the bad guys could still steal the card or get hte card number and capture CVV2..  MasterCard and Visa then created SET, 3D-Secure and now, as for profit owners of EMVCo, are proposing, maybe even will mandate, the industry implement EMV 3D-Secure.

Each, an attempt to provide some means of Authentication and Verification.

Each introducing a level of friction as a means of security.

This is the problem.  The market did not start by emphasizing the need for security by educating the consumer.  The industry needed to help the consumer understand they should care and want to securely pay for what they intend to buy.

Instead:

  • The Zero Liability Policy was adopted.
  • The merchant was more than happy to sustain a degree of lose (fraud) in exchange for sales and profits.

The result, as all anticipated would happen, was blissfully ignored and eventually they cried out about.

Fraud migrated to the weakest point
Just like water finds its way to the lowest point. 

EMV, introduced in the Face to Face card present environment, pushing the bad guys: be they criminals, state actors and terrorists to find alternate another channels for their financial gain.

EMV and now the recently published WebAuthN and FIDO specifications create effective mechanisms for Consumer Authentication.

Let us please remember – the PAN, a user name, your social security number or your email address are excellent Identifiers.  They should not be authenticators and they are not a means of “Identification”.

Let us also remember, the term Identification means that one is assured of the irrefutability of identity.

The big question:

  • Why did we have to get rid of or replace the PAN?
  • Why did we and continue to need to invent and invest in all this addition overhead?
  • Why did we not simply address authentication?

Some will argue the challenge of using the PIN or a Password, as a means of Verification, is because it is to hard to remember. Especially, if each password people use to access website, services, building, has to be unique.  Some will argue imposing friction to add security is not convenient.  Others will remind us that security is and has been a necessity since the beginning of time.

Why didn’t we when we created this great new digital shopping mall?

Bottom line each of the devices used to present or acquire the PAN, must be capable of authenticating the identity of the authorized presenter, in both the physical and virtual world.

At least these are the views of someone who believe history provides a baseline for tomorrow and tomorrow must be designed as a function of where you want to be, knowing where things came from.

 

Federation and the Identity Provider

This year, one of many discussions I’ve been involved in revolved around these two foundational terms. In our digital environment and in support of an ever increasing array of people – individuals – engaging and interacting in the physical and virtual world, the questions – who are you and who can prove who you claim to be – becomes a critical element of establishing business and social relationships.

“Once Upon a Time” we lived in villages and knew our neighbors. When we travel afar, we would go with a letter of introduction from a Lord or other important, known and recognized person. A credential signed and sealed would assure safe passage and presented as. Proof of Identity upon arrival. Trusted identify established via a signed and sealed inside a Letter of Introduction.

Federation is a mechanism to convey a proof of identity in a digital world.

of Tokens and Things

Things, now there is a big word.

  • I am a thing
  • It is a thing
  • I know a thing
  • Things must therefore be anything

The dictionary rambles on about things.

Tokens, What is this thing?

Tokenization why is everyone so excited?

Tokenization and the Search for Identity

The belief in tokens emerges from the need to address security in a world where an identifier becomes an authenticator.

The PAN on the front of a ID-1 Card defined and governed by the International standard IS)/IEC 7812-1. When it was originally conceived there was no desire to turn the PAN into PII Data. They simply wanted the PAN to be an index, “a pointer” “an Identifier”, to an account, or relationship, a card issuer (financial institution) created between itself and the cardholder. In our quest to take advantage of the telephone, the mail and ultimately the internet as a set of sales channel. The Payment System actors agreed if the card acceptor “merchant” would accept liability. Then, they could simply use the PAN, the expiry data and cardholders name to effect a card payment. This acceptance of liability was an acknowledgement they could not inspect the card and verify that the physical security features where present, hence the token was not present to be authenticated.

Society in its infinite wisdom followed another path with the Social Security Number. A number originally designed to act simply as a unique value representing each person here in the United States. Unfortunately, as is often true, we took the short cut, assumed this number, stored on hundreds of databases and recorded on an equally large number of forms, could be used to authenticate that you the individual was present.

mysteriously and without thought society allowed these numbers to take on values they where never intended to assume. They became “secrets” number that if known to another could be used to take over our identity. They can make payments in our name. They can apply for loans and take over our financial assets without the true individual being the wiser.

Those that seek to profit and do not share societies morality find ways of taking advantages of our desire to cut cost and reduce friction. They create near perfect counterfeits of these tokens, they take advantage of our naivety and they seek to disrupt and profit.

We could do as we have often done in the past – replace the token with a token. We could claim by tokenizing these identifier with another vale we were adding layers of security. We argued that if this new tokenized value could only be used by that merchant or with that physical device; security would be restored. The question how long would that new think provide the security its champions claimed it would offer.

Payment Card Construct and Dual Interface Deployment

Payment Card Construction

The discussion focused on the construction of the sandwich. Four layers. Clear front laminate to protect the ink, front with the banks design and brand logo, back with the banks back design and a clear laminate with the magnetic stripe integrated into it.

To enhance design additional layers may be added, such a metal foil.

These four sheets are then bonded together, at 120 degrees, in sheets of 21, 36 or 48 or other various sheet sizes. Next step punch out cards, add hologram and signature panel.

For a standard EMV card the next phase is to mill and embed the module with the chip inside. Last, the manufacturer typically loads the O/S & EMV application into the integrated circuit card.

When we move to dual interface caed, this process is modified to add an inlay, with the antenna embedded within. This inlay is inserted in the middle of the sandwich and during the embedded process the contacts exposed on the base of the module are connected to the antenna in the inlay.

Next step, personalization, when the appropriate data is loaded into the chip, along with the encoding of the magnetic strip and printing and/or embossing of the cardholders, name, expiry date, cvv2 and other information onto the card.

Contactless or Not That is a Question

Contactless NFC acceptance and dual interface issuance is all about the chicken and the egg. Who will go first? The merchant or the issuer? Each need each other. Both are wondering about the incremental value.

  • Faster transactions – Yes
  • Less cash – maybe
  • More revenue – good question!
In other parts of the world, transit and their choice of contactless, as the right answer to a more efficient fare collection solution is driving conversion. In other, markets a group decision to adopt or a desire to find the next great thing drives the market. Here in the USA, we have a less than successful history of contactless. Let’s not forget PayPass and PayWave, it was tried the middle of the last decade, to little or no success.
We have Google and the FinTech world looking to mobile payments as the next great adventure. Merchants, like Wal-Mart, are resisting NFC acceptance given their own plans for QR based wallets and desire to limit the sharing of data with competitors.

Given these questions and observations, one can only wonder.

Financial Trade Groups Write to House Leaders in Support of Data Breach Notification Bill

https://bankingjournal.aba.com/2018/02/financial-trade-groups-write-to-house-leaders-in-support-of-data-breach-notification-bill/

February 28, 2018

 The American Bankers Association and six other financial trade organizations wrote to House leaders today underscoring the need for businesses across all industries to be held to the same data protection and breach notification standards currently adhered to by regulated financial institutions.

The associations expressed support for draft legislation released by Reps. Blaine Luetkemeyer (R-Mo.) and Carolyn Maloney (D-N.Y.) that would create a level playing field of nationally consistent data protection standards and post-breach notification requirements. This bill would not create duplicative standards for financial institutions which are already subject to robust standards, but rather extend similar expectations to other sectors that handle consumer data.

“The goal of the bill is simple — raise the bar so that all companies protect data similar to how banks and credit unions protect their data, and create a common-sense standard to ensure consumers receive timely notice when a breach does occur,” the groups wrote.

The draft bill contains a provision that recognizes the existing, effective regulatory framework for covered financial sector entities.  While the provision was intended to prevent banks and credit unions from being subject to duplicative notification requirements, it has been the target of recent negative campaigns circulated by the National Retail Federation and the Retail Industry Leaders Association, which incorrectly suggested that banks do not notify customers of breaches on their computer systems and   The ads from the retailer groups also mischaracterize and exaggerate the share of data breaches occurring at banks and credit unions while omitting their members’ (higher) share of data breaches.

The financial trades refuted the notification assertion, noting that “banks and credit unions have long been subject to rigorous data protection and breach notification practices for financial institutions to follow,” and that in the event of a data breach, banks and credit unions work continuously to communicate with customers, reissue cards and enact measures to mitigate the effects of fraud. They added, however, that “no solution will work unless everyone has an obligation to take these steps.” For more information, contact ABA’s Jess Sharp.

The management of our identity

A few weeks ago I learned of the Sovrin Foundation a foundation interested in establish a concept to support the idea of a self Sovereign means of identity.

As an advocate for stronger forms of identification and more important Authentication I am pleased to have received your response today.

Back in 1993 I was part of Europay and drove the creation of the EMV specifications as a form of Authentication and frankly reflecting back a strong form of Identification with the Trust Anchor being the Financial institution issuing the card and the foundation anchor being the payment network that the issuer used to assure acceptance globally.

In 2013 I joined the Board of the FIDO Alliance and eventually become the Secretary of that Board.

Today I am engaged with a company called IPSIDY, that is promoting and selling Identity as a solution.

Clear the conversations we are having include:

  • Device based versus centralized biometric authentication
  • Identification based on a central repository of Biometrics or a simply identifier linked to a means of authentication
  • Claims and assertions one points (URL) to or those that one has in their own possession
  • Repositories or Distributed databases of information
  • Privacy of attributes and rights to defining what can be shared

When I ask about the future of Sovrin, I hear people saying great concept how does it scale to be useful. 

This, as was my experience in the Payments world, is the challenge of a  two sided market

  • Consumer – Merchant
  • Individual – Rely Party and those seeking attributes and proofs of identity

The challenge is developing a value proposition and more importantly critical mass that will excite both sides of the market to want to participate.

To further complicate developing the market is the challenge of the “Go To Market” strategy.  Who does one partner with given that the usefulness to the citizen/consumer is predicated on the number of parties or places this solution, token or Identity with a set of sharable attributes can be usefully used.

 

This is the question this is the challenge.

 

A Shift from Check-out to Check-in will reshape the way merchants engage with their consumers

Think Uber, think order ahead, think account on file. With these ideas in your mind think engagement and Omni channel. Then consider the need of merchants to assure revenue by delighting and engaging with their customers in meaningful ways. Their focus, increasing basket size, more frequent visits and loyalty; in other words increased sales.

Then remember, Check-out is about friction, payments and long lines. These characteristics merchants seek to eliminate, reduce the cost of and enhance the experience around.

If we think Check-in, using big-data, geo-location, BLE, facial recognition, consumer centric apps and other techniques, we can image a world where human and device based personal assistants engage with the merchants loyal customers in a friendly, informed and satisfying way.

For payment people this means we need to remember that merchants want lower cost payments and friction-less check-out.

Bottom line, for loyal customers solutions that retain the payment credentials securely in the cloud. For one time and infrequent customers, they will look to incent loyalty and registration or simply accept classic means of payments e.g. cards.

This drive to move from recording a loyal customers visit to engaging when the customer arrives or better yet when they are doing their research is what we the consumer seek.

We are all about saving time, enjoying life and satisfying our needs and wants. Merchants that focus on the customer and their shopping experience will succeed and prosper./ Those that do not focus on delighting their customer will learn.

DIY the Cyber Guy a conversation about Bitcoin and EMV 

https://www.voiceamerica.com/promo/episode/104814

A interesting discussion withDavid the the Cyber Guy.  We spoke of the inherent risk of Bitcoins and the essential issue of the secret and a BitCoin folders resoponsibility to make sure they never lose the secret.

We then wandering off to talk about EMV or Chip and Pin.

Always a pleasure to work with David.

Words all bound to who we claim to be – How do we identify ourselves on the Internet or in Cyberspace?

Identifier – Something you create or are provided to digitally identify yourselves. Identifiers are things like an alias, user name, email address are examples.

Identity – This is who we are or wish to represent ourselves to be. These are attributes and information about: where we live, who we work for, which banks we have relationships with, who our friends are, which clubs we belong to, our certified skills, what schools we graduated from, which country(s) we are citizens of, our LinkedIn profile, Our Twitter handle, our Facebook identifier, our phone number … .  It is the sum of the attributes we can and will share with others, be they individuals, governments, entities or organizations; as we establish relationships and prove to them who and often what we are.

Authentication – The method we employ to assure that you, based on the identifier presented, are who we (the relying parties) thinks you are.  You are the person the relying party accepted when you registered that Identifier as how you would digitally identify yourself.  By itself the method of authentication should not allow another party to be able to determine anything about your identity.  Privacy is the goal.  FIDO Alliance and W3C have defined standards to support authentication.

Verification – The process of confirming that the secret or biometric match the secret or biometric that where originally registered to that Identifier.

Identification – A means of authentication that is bound to your identity.  A EMV payment instrument “Chip and PIN”, a PIV card, an electronic passport, a membership card, a drivers license, a national ID are all forms of identification  issued by a party that should be trusted to have performed a proof of the individuals Identity, based on a defined and often published criteria.

This particular word, for many, has an alternate meaning.  In the biometric community they see Identification as the ability to use a biometric to determine ones Identity.  This is achieved by performing a one (the person present) to many match (persons registered).  The goal is the same, bind Identity to the mean of Authentication by using the Biometric as the Identifier.

Proof – The method a relying party or an individual uses to validate your claim of a specific Identity.  In many cases this is achieved by relying on knowledge of another party.  The relying party accepts the due diligence to proof your claimed identity was done to their satisfaction by another party.  This other party is often referred to as a Trusted party.  This effort to proof the identity of an individual is linked to words and acronyms like KYC “Know Your Customer”, ID&V “Identity and Verification” and Self Sovereign Identity.  We classically assume that documents provided by a Government e.g. drivers License and Passports are a solid proof of the claims asserted on those same documents.

In a digital world this is the most important element of a how we as people, entities, governments and corporations can be assured that you are who we believe you to be.

I am once again am reminded of the 1994 New Yorker Cartoon

The challenge of voice recognition and the need for multiple modalities to the question of authentication

A Good Mimic Can Bypass Voice Recognition Authentication, Research Suggests

The idea of voice many see as one of the more interesting biometric solutions as seen from an ergonomic perspective and something that can readily enhance the call center consumer experience and related security.  The user simply needs to say something into a microphone (telephone) and presto they can be identified or authenticated.    

But is it a safe and secure approach or simply the starting point for the identification and therefore associated with additional authentication processes. 

Personally I am not convinced a voice is a good solution to the challenge of authentication.  Yes, as one element of a multi-factor multimodal approach it is an excellent modality.  But not as the only biometric modality.  My fear emerged from a conversation with a sound engineer.  She told me they could, at the level of a single vowel, splice and change the intonation of a word in a movie sound track.

The above article clearly identifies real world examples of voice biometrics being fooled and concludes by remind us that a multimodal solution is essential. 

Classic Multi-Factor Authentication wants to pair multiple unique and none replicable elements together.

  • Some thing you have
  • Some thing you know
  • Something you are

When I think about multi-factor authentication I wonder what would happen if the object “what you have” can be stolen.  This therefore means the second factor must to assure that only the legitimate user is presenting the object.  If a mime can replicate a voice, after stealing the object, then, this combination of factors can be compromised.

EMV, when implemented as Chip and PIN, matches a unique chip card (what you have) with a PIN (what you know).  Apple Pay is EMV and stores the secrets and executes the cryptographic functions, inside hardware, the Secure Enclave (what you have) and combines this with a sensor to capture the Biometric (what you are).  The electronic passport ICAO use similar chips and carries within it a facial image.  The US PIV & CAC cards uses the same style Chip and are paired it with a fingerprint and sometimes also requires the user to enter their PIN.   

Yet are they truly secure?  We know  Apple X’s, facial recognition, as currently implemented, can be fooled.  We know that Touch ID  was spoofed.  Without liveness testing, most if not all biometrics, will accept a clone or replica of the biometric it employs. 

The challenge is establishing the appropriate benchmarks for the various biometric implementations such that enterprises, governments, merchants and corporations can select and implement a consumer experience that satisfies the needs of security and convenience.

Acronyms like FRR, FAR and PAD become critical to selecting the appropriate implementation of a biometric solution.

  • The False Reject Rate or FRR is all about convenience and not refusing the legitimate user. Perfection is a ratio of 0 in ∞
  • The False Accept Rate or FAR is all about not approving a transaction or event by an imposter. Perfection is a ratio of 0 in 1
  • The Presentation Attack Detection or PAD is all about addressing the reality that anything can be duplicated; therefore it is essential to make sure the biometric presented in alive and genuine. Perfection is a ratio of 0 in 1.

The challenge is establishing  a balance between the cost and the acceptable FRR, FAR and PAD.

Measuring and establishing the test results of a particular element of a multi-factor solution is not cheap.  EMV, PIV, ICAO software and “Secure enclave” / “Chip Card” / “Secure Element” suppliers spend 100’s of thousands of dollars developing and certifying the functional and security characteristics of the “what you have” element of these solutions.  We know that passwords and PIN can and have been compromised with Phishing attacks and hidden cameras.

When we think about  biometrics there is complexity in the read and match processes.  When the user established their identity and their biometric the reference template is create.  This reference template is then used in the matching process to identify if template resulting from the biometric just presented, is the same.  Unfortunately reality dictates that each presentation of the user’s biometric will generate a unique result.  This unique result will never absolutely match the reference template.  Hence the need to understand and test the sensor and establish its FRR, FAR and PAD.   The more foolproof the match must be, dictates the complexity of the solution and the number of different individual needed during the test process to establish the sensors FRR, FAR and PAD.

Therefore selecting the most appropriate solutions means quantify the risk of the event or transaction and measuring it against the cost and certified characteristics of the authentication mechanisms.

A layered approach that combines two or more factors must also considered including multiple modalities for at least the “what you are modality” is what we must consider.  Using cryptography and hardware to address what you are, Passwords and demographic information to match what you know and layering various elements like location, behavior and some set of biometrics to understand who you are, will offer the highest level of security with the lowest degree of inconvenience.

Bottom Line Multi-Modal & Multi Factor

Authentication of Identification is what we must implement

Always mindful a modality will lose its ability to assure uniqueness

Over time.

We must take care when we speak or sell the power of that which may not be

I always enjoy reading the words David writes.

This particular post creates a moment to reflect.  As we consider the implications of the  Fourth Industrial Revolution, we must remember the  significance many have attributed to Artificial Intelligence.  Those two letters AI are clearly key to the what, why and wherefore of the change ahead.

Clearly machines that work faster, search deeper and are capable of studying vast realms of data are changing the nature of so much.  Simply consider the risks to our security cyber hackers and terrorists wrought on this world or the shenanigans many claim the Russians use to disrupt as they explore and exploit the power of social media.

Moreover as we look afield many industries are being disrupted: movies, books, music, news … to name few.   Outsourcing and robotics is changing the nature of work and the skills necessary to compete and ultimately survive to enjoy the pleasures available in our increasingly digital world.

David makes the point that the intelligence Isaac Asimov and other science fiction envisioned has not yet emerged.  I think he is right.  The message I take aware -we who  market these  solutions should walk forward with care.

People are clearly feeling threatened by the change impacting their towns, families and livelihood.

We must be mindful that complexity breeds confusion.  Confusion drives disillusion.  This then causes people to react, often in nonsensical  ways.

How Intelligent Is Artificial Intelligence?

Posted: Nov 27, 2017 10:51 am

At the recent Money20/20 conference, sessions on artificial intelligence (AI) joined those on friction in regulatory and technological innovation in dominating the agenda. A number of panels highlighted the competitive advantages AI tools offer companies. It didn’t matter if the topic was consumer marketing, fraud prevention, or product development—AI was the buzzword. One speaker noted the social good that could come from such technology, pointing to the work of a Stanford research team trying to identify individuals with a strong likelihood of developing diabetes by running an automated review of photographic images of their eyes. Another panel discussed the privacy and ethical issues around the use of artificial intelligence.

But do any of these applications marketed as AI pass Alan Turing’s 1950s now-famous Turing test defining true artificial intelligence? Turing was regarded as the father of computer science. It was his efforts during World War II that led a cryptographic team to break the Enigma code used by the Germans, as featured in the 2014 movie The Imitation Game. Turing once said, “A computer would deserve to be called intelligent if it could deceive a human into believing that it was human.” An annual competition held since 1991, aims to award a solid 18-karat gold medal and a monetary prize of $100,000 for the first computer whose responses are indistinguishable from a real human’s. To date, no one has received the gold medal, but every year, a bronze medal and smaller cash prize are given to the “most humanlike.”

Incidentally, many vendors seem to use artificial intelligence as a synonym for the terms deep learning and machine learning. Is this usage of AI mostly marketing hype for the neural network technology developed in the mid-1960s, now greatly improved thanks to the substantial increase in computing power? A 2016 Forbes article by Bernard Marr provides a good overview of the different terms and their applications.

My opinion is that none of the tools in the market today meet the threshold of true artificial intelligence based on Turing’s criteria. That isn’t to say the lack of this achievement should diminish the benefits that have already emerged and will continue to be generated in the future. Computing technology certainly has advanced to be able to handle complex mathematical and programmed instructions at a much faster rate than a human.

What are your thoughts?

Digital Identity

Words to ponder as we think about the best way to secure our digital persona.

Identifier – A text string we use to uniquely identify ourselves to a relying party, person, government, employer, club or entity we wish to have or need to maintain a relationship with.  This group of entities hereafter will referred to as a replying party. 

Identity – We each are unique and have attributes 

Verification – A process the entity we seek to establish a relationship with uses to determine the truth of the attributes we share. One could argue this is or should be a mutual process.  Many call this identity verification or identity proofing.

Registration – When we take these three words identifier, verification and identification and think about the first time we present ourselves to a relying party in the global digital environment. We typically present ourselves through a user interface to the entity we are interested in establishing a relationship with.  We register and the relying party creates a record of our existence.  They seek to recognize and record our identity.

This process typically requires us to invent or the relying party to present us with a unique identifier and agree to identify ourselves with this unique string, often called a user name, email address, bank account number, social security number, employee id, passport number, drivers license number or payment (card) account number ‘PAN’.  The ultimate goal of registration is for the relying party tonassure themselves we are unique and that the attributes we share are linked to our person. They verify our identity.

Today the challenge is to find an efficient, convenient and none intrusive method of Verification.

Authentication – We exist, we can be recognized and are able to present oneself over and over again to the relying party, using our identifier.  The challenge is how do we prove or assure our identity to the relying party each time. We need to authenticate ourselves.

Identification – Many confuse the dialogue above with this word.  The difference is how we present ourselves or better said how the relying party expects us to present ourselves.

With the wide use of biometrics and  many of the identifier we spoke of earlier, our identifier many not simply be some random string.  A biometric is personal and linked to our body or actions.  This biometric can be converted into an identifier and therefore once accepted as genuine and integrates the act of authentication into recognition of our identity.

Certain identifiers create a level of assurance, because the relying party trusts the attributes it asserts based on who issued that identifier.  They are willing to trust in our identity and associated attributes because of the verification done by the isuing party.  It a passport, an employee id, bank card or a drivers license.  The instrument has characteristic, privileges and attributes linked to the issuing party, not simply attributes associated with the individual.

As we move from a physical world to a digital world.  As people seek to use our identity to present themselves as someone they are not.  As we seek to separate the various relationships we establish.    Requires that we find ways of assuring our privacy while securing our relationships.  All this demands we find more secure methods of authentication that are convenient. 

Thinking about cards

In 1991 I had to learn the difference between million dollar transactions and hundred dollar transactions. As I came to explain, when telling my life story, I had to shift my thinking from 100 transactions at a million to 1,000,000 for a hundred. This transition took me from capital markets to payment cards.

Today, I wonder about the future of the ID-1 based payment card? A piece of plastic 3 3/8 x 2 1/8 with rounded corners.

In another blog I spoke of how this ID-1 object became a token responsible to act as the first factor, something you have. Printed, encoded and embossed characteristics were the security features. Today, with EMV as the global standard for payment CARD security; cryptography and the “secure element” replace those physical security with digitally mastered circuitry embedded inside something capable of protecting those secrets cryptography requires. We digitized the payment card. What we now must do is shift our vocabulary to tokens and credentials.

We need to embrace a new way of speaking we need to think about our “Payment Credentials”.

Today, we now tap our phone to pay, we use our phone to browse the internet, we shop & book tickets with apps and we listen to music & watch movies all from this device we apparently use, thousands of times a day. For those of us who remember computers that filled floors, we now are capable of buying more powerful computers, similar in size to those same cards. Think about the Raspberry Pi, a computer almost as small as a card, not quite! Yet!

The embedded secure element integrated inside our payment cards are being integrated into phones, bracelets, rings and things. The question; will they replace the card we are now comfortable with? Yes – maybe? Will we embrace these objects as the new carriers of our payment credentials? Many hope so.

In oder to think about the probability of cards disappearing, one must begin by think about the number of cards now in circulation. In round numbers we can think about 1.2 billion debit and credit cards, 300 million prepaid cards and 300 million retail branded cards. In round numbers, 1.8 billion payment cards. We next must think about our population and how many people now carry cards – 115 million households and 242 million Americans over the age of 16, according to a recent census. We now has a numerator and a set of denominators.

The question then becomes, how many payment cards does an American want to carry and how many payment credentials will an American end up having.

I would argue a debit card and a credit card is all we need to carry in our leather wallet, purse or pockets. Those other payment credentials can easily be accessed from wallets in the cloud or in our digital objects.

Merchants can integrate payment capabilities and focus on factoring their consumer receivables, behind relationships designed to service, thrill and sell. In an App and API enables economy, cards become a burden as the experience becomes the essential component of our lives.
