When biometric readers are “magic” (it’s a small face after all)

(Part of the biometric product marketing expert series)

The news coming across the wire is that Disney’s Magic Kingdom in Florida is testing facial recognition. (H/T International Biometrics + Identity Association.)

“At Walt Disney World Resort, we’re always looking for innovative and convenient ways to improve our guests’ experience—especially as we navigate the impact of COVID-19. With the future in mind and the shift in focus to more touchless experiences, we’re conducting a limited 30-day test using facial recognition technology.”

If the test is successful and facial recognition is implemented, it would be a replacement for (touch) fingerprint technology, which the Disney parks suspended last July for health reasons. (Although touchless fingerprint options are available.)

Disney’s biometric history extends back to 2006, when it used hand geometry.

The five authentication factors

(Part of the biometric product marketing expert series)

I thought I had blogged about the five factors of authentication, either here or at jebredcal, but I guess I haven’t explicitly written a post just on this topic. (You’d expect an identity content marketing expert to do that.)

And I’m not going to do that today either (at least in any detail), because The Cybersecurity Man already did a good job at that (as have many others).

However, for those like me who get a little befuddled after authentication factor 3, I’m going to list all five authentication factors.

Something You Know. Think “password.” And no, passwords aren’t dead. But the use of your mother’s maiden name as an authentication factor is hopefully decreasing.
Something You Have. I’ve spent much of the last ten years working with this factor, primarily in the form of driver’s licenses. (Yes, MorphoTrak proposed driver’s license systems. No, they eventually stopped doing so. But obviously IDEMIA North America, the former MorphoTrust, has implemented a number of driver’s license systems.) But there are other examples, such as hardware or software tokens.
Something You Are. I’ve spent…a long time with this factor, since this is the factor that includes biometrics modalities (finger, face, iris, DNA, voice, vein, etc.). It also includes behavioral biometrics, provided that they are truly behavioral and relatively static.
Something You Do. The Cybersecurity Man chose to explain this in a non-behavioral fashion, such as using swiping patterns to unlock a device. This is different from something such as gait recognition, which supposedly remains constant and is thus classified as behavioral biometrics.
Somewhere You Are. This is an emerging factor, as smartphones become more and more prevalent and locations are therefore easier to capture. Even then, however, precision isn’t always as good as we want it to be. For example, when you and a few hundred of your closest friends have illegally entered the U.S. Capitol, you can’t use geolocation alone to determine who exactly is in Speaker Pelosi’s office.

Now when these factors are combined via multi-factor authentication, there is a higher probability that the person is who they claim to be. If I enter the password “12345” AND I provide a picture of my driver’s license AND I provide a picture of my face AND I demonstrate the secret finger move AND I am within 25 feet of my documented address, then there is a pretty good likelihood that I am me, despite the fact that I used an extremely poor password.

I don’t know if anyone has come up with a sixth authentication factor yet. But I’m sure someone will if it hasn’t already been done. And then I’ll update to update this post in the same way I’ve been updating my Bredemarket 2021 goals.

Identity assurance levels (IALs) and digital identity

(Part of the biometric product marketing expert series)

There is more and more talk about digital identity, especially as COVID-19 accelerates the move to contactless and remote transactions. However, there are many types of digital identity, ranging from a Colorado, Louisiana, or Oklahoma digital driver’s license to your Facebook, Google, or Microsoft ID to the online equivalent of my old Radio Shack Battery Club card.

All of these different types of digital identities suggest that some identities are more rigorous than others. For example, I’ve lost track of how many digital identities I’ve created with Google over the years, but if California ever gets around to implementing a digital driver’s license, I’ll only have one of them. (And I won’t be able to get another license in Nevada.)

In this particular case, the government IS here to help.

The U.S. National Institute of Standards and Technology has defined “identity assurance levels” (IALs) that can be used when dealing with digital identities. It’s helpful to review how NIST has defined the IALs. (I’ll define the other acronyms as we go along.)

Assurance in a subscriber’s identity is described using one of three IALs:

IAL1: There is no requirement to link the applicant to a specific real-life identity. Any attributes provided in conjunction with the subject’s activities are self-asserted or should be treated as self-asserted (including attributes a [Credential Service Provider] CSP asserts to an [Relying Party] RP). Self-asserted attributes are neither validated nor verified.

IAL2: Evidence supports the real-world existence of the claimed identity and verifies that the applicant is appropriately associated with this real-world identity. IAL2 introduces the need for either remote or physically-present identity proofing. Attributes could be asserted by CSPs to RPs in support of pseudonymous identity with verified attributes. A CSP that supports IAL2 can support IAL1 transactions if the user consents.

IAL3: Physical presence is required for identity proofing. Identifying attributes must be verified by an authorized and trained CSP representative. As with IAL2, attributes could be asserted by CSPs to RPs in support of pseudonymous identity with verified attributes. A CSP that supports IAL3 can support IAL1 and IAL2 identity attributes if the user consents.

Interestingly, the standard assumes that pseudonymous identity can be proofed…but this requires that SOMEONE know the actual identity.

And in practice, the “physical presence” requirement of IAL3 can be met by either being “in-person,” or in a “supervised remote” case. (This is needed to make sure that I don’t register with someone else’s face, for example.)

So when considering the robustness of any digital identity scheme, it’s necessary to ascertain whether the digital identity can reliably be mapped to a real life identity. This doesn’t necessarily mean that IAL1 is bad per se; in some cases, such as my old Radio Shack Battery Club example, a robust mapping to a real life identity is NOT necessary.

But in other cases, such as a need to gain entrance to a nuclear power plant, that reliable mapping IS essential.
