Facial authentication systems from Lenovo, Asus, and Toshiba have been defeated by researchers. Apparently a variety of methods were used, including presenting a picture of an authorized user to the system. Fun stuff! There will be a briefing on this next week at Blackhat DC.
Hmm, I'm surprised that news is so recent. Wasn't there an article about that a while back? I thought I had read something similar a while ago about presenting a picture to facial recognition software... the post about it was probably here in forums.
Now that's scary especially considering the fact that biometric authentication is considered to be one of the most secure methods. I guess Vijay will give us more info. after he attends the Blackhat DC briefing.
