‘Harmful for security or privacy’ OR ‘Harmful for both security and privacy’

The situation still the same, I bring back an article posted 13 months ago.

From one view angle, biometrics would be harmful for ‘privacy’ if as accurate as claimed or would be harmful for ‘security’ if not so accurate.

From another view angle, biometrics is harmful for ‘both security and privacy’ irrespective of whether accurate or inaccurate.

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.

Expanded Password System to Complement FIDO2

2 is larger than 1 but is not necessarily stronger than 1, as two children could be overwhelmed by a grown-up. For a two-factor authentication to be really reliable, each factor should be reasonably secure and usable enough. On the other hand, ‘password-less’ authentication, however attractive it might sound, would only benefit bad guys as examined in the link page - https://www.linkedin.com/pulse/removal-passwords-its-security-effect-hitoshi-kokumai/ People who offer a token as 'a factor' of two factor authentication schemes could all be viewed as our potential down-stream partners. Among them are the people who offer FIDO2-compatible solutions. Put together, we could come up with the two-factor authentications that are much more reliable than otherwise.

Robust 2-Channel Authentication

2 is larger than 1, but not necessarily stronger than 1. https://www.theregister.com/2020/07/20/twitter_security_update_hackers_broke_2fa/ By bringing in the concept of Expanded Password System, we are able to protect important accounts more reliably than conventional 2-factor/step authentications as outlined here – “Advanced Persistent Threats in Digital Identity” https://www.linkedin.com/pulse/advanced-persistent-threats-digital-identity-hitoshi-kokumai/ This is not a hypothesis. It has been quietly but effectively deployed since 2014 for a security-centric corporate network by 1,200 employees. Needless to say, asymmetric cryptography could be additionally incorporated for yet higher security where needed.
