Probabilistic Is Human Body, Not Pattern-Matching Algorithm

Probabilistic Is Human Body, Not Pattern-Matching Algorithm

The probabilistic nature of biometrics comes from the unpredictably variable body features of living animals rather than imperfect algorithms of pattern matching; perfection of pattern matching algorithm would not affect the probabilistic nature of biometrics.

Biometrics that measures the probabilistic body features does not escape False Rejection/False Non-Match/False Negative that inevitably comes with False Acceptance/False Match/False Positive.

Since it cannot escape FR/FNM/FN, biometrics cannot escape the dependence on a fallback measure, a default password/pincode in most cases, which brings the security to the level lower than a password/pincode-only authentication.

And yet, so many people who need higher security are spending so much money for bringing security down.

A default/fallback password is the password, isn’t it?

 Let us infer what biometrics promoters and adopters would assert in order to justify their allegation that biometrics, while depending on the password, can displace the password.

 It could be "We are aware that consumers have to rely on a default password as the fallback measure in case of false rejection. But, the consumers can complete the authentication without using the password/pincode when they are not rejected by the biometrics. This observation encourages us to assert that biometrics enables us to achieve a password/pincode-less authentication while providing good convenience to citizens".

 What they would not mention is "We are not interested to talk about the reality that the adoption of biometrics has enabled criminals to capitalize on the two entrances placed in a 'multi-entrance' deployment which has brought down security to the level lower than a password/pincode-only authentication. Convenience that we offer actually benefits criminals."

True that. Convenience and (cyber)security are rivaling factors. Cheers
