Privacy-Preserving Biometric Authentication (passwords, security, signals, scan)

[GabrielLuke]

Biometric authentication is a quick, accurate and user-friendly tool that provides an efficient and reliable solution in many access control systems. A typical example of biometric authentication (BAS) systems is sensor access control systems (for example, for iris or fingerprint scanning).

In this case, the sensor takes the biometric feature of the person requesting access, which is only given when the person is identified as the authorised user of the system. One of the main advantages of biometrics is that it is not necessary to store complex passwords or carry chips because they cannot be forgotten or lost.

While BAS systems offer significant user friendliness benefits, they are threatened, just like any other security system. However, for biometric authentication, successful attacks can have serious consequences for the lives and privacy of users. Unlike passwords or signals, Biometric Identification cannot be kept confidential or hidden, and stolen biometric data cannot be revoked as easily.

This is a problem with all types of security, there are plenty of people willing to defy it.
The RFI chip is just as vulnerable.

1st post? BOT. Nothing to see here.

Right, and its often said, when new security technology comes out, the criminals have usually already figured out a way to defeat it or go around it.


A great example is the new 'real' IDs that all states will have within a couple years, I saw that they have already figured out how to make a fake one, and most states dont even have the ID yet! lol

And one of the main disadvantages is that once I provide my fingerprint, retinal/iris image, or DNA to someone else, I am entirely dependent on them storing it in an absolutely secure system, because once they've allowed someone else to gain access to it, there's no way I can reset it like the terrible, terrible password burden. Sheesh. Has everyone already forgotten how 2 of our credit reporting companies (to whom I never gave permission to access my financial information in the first place) irresponsibly gave up that information last year to other people who shouldn't have had it?

The difference is that you can replace a chip, password, phone, etc. much easier than you can replace your iris, fingerprint, etc.

^This.

In many of the enterprise AC systems - they don't actually keep your raw biometric info. It's essentially more like a hash. When you authenticate, the hash values are compared to make sure they match.

Thus, compromising the system will not compromise your biometrics unless they actually compromise the input device and intercept the scan (essentially, "cutting your finger off" virtually).
