South Korea based Samsung has modified Android 4.0 Ice Cream Sandwich Face Unlock system to boost it’s security credentials, addressing criticisms that the facial-recognition system can be duped by a photograph. That keep unwanted guests from accessing your smartphone and data using a photograph. In the past it has been possible for the Face lock feature to be duped into providing access using just a photograph. In the past Google has claimed that the lock-screen alternative was more gimmick than true biometric security.
But now Samsung has changed the system, however it now requires the owner to now blink in front of the Face Unlock screen to prove they are not a photograph. So anyone thinking of accessing an Android smartphone using just a photograph will now have to use an animated Gif image to gain access instead. The security is still unlikely to be foolproof, though it does make it a little less straightforward to trick into unlocking.
