Fooling biometric face recognition

CNet has a nice article about a Vietnamese company called BKIS that was able to login to the reporter’s laptop by simply recording him in a video chat and then using the blurry printout to authenticate with the face-recognition software.

I like to make fun of biometric authentication, mainly because it was overhyped in the 90′s as the authentication that will make remembering passwords obsolete. But it’s not useless technology – you just have to know how to use it.

Using a biometric system (this, or another) in a public place with a guard watching is good enough to make it difficult to hack. I imagine even a minimum-wage rentacop will notice when someone looking like Tom Cruise comes up to the biometric system with someone’s eyeballs in his hand. They should even notice if I come with a printout of someone else’s face. The same is true for passwods: a 50-character long password can be practically as strong as a 4 digit PIN if the proper lock out procedures are in place. Likewise, if I can try billions of password combinations per second then the difference between guessing a 8 character password and a 10 character password is just a few hours.
