My Face is Your Face and also Their Faces, isn’t it?

My Face is Your Face and also Their Faces, isn’t it?

Worry about a backdoor?

Today’s topic is this intriguing report - “'Master Face': Researchers Say They've Found a Wildly Successful Bypass for Face Recognition Tech” https://gizmodo.com/master-face-researchers-say-theyve-found-a-wildly-succ-1847420710

It reads “computer scientists at Tel Aviv University in Israel say they have discovered a way to bypass a large percentage of facial recognition systems by basically faking your face. The team calls this method the “master face” (like a “master key,” harhar), which uses artificial intelligence technologies to create a facial template—one that can consistently juke and unlock identity verification systems.”

Those researchers have found a way, in our wording, “to drastically increase the False Acceptance Rate of face identification systems”, meaning that face biometrics, when used with a weak default password, would drastically destroy the defense that the weak default password has somehow provided, 

The destruction mechanism is examined in this post - https://www.linkedin.com/posts/hitoshikokumai_identity-authentication-password-activity-6825637129641701376-XgjN">Biometrics is to Password what Back door is to Front door

You know, you can share this in groups too, to make it known to more people that biometrics the way they are implemented aren't secure…
