Samsung has said in the past that its Face Unlock feature isn't created to be the most secure option, rather as a convenient alternative to entering a code or using your fingerprint, and has prevented the tech being used for mobile payments.
Samsung is basically saying, if this is truly a flagship phone, then let's fill up the Samsung Galaxy S8 with more features than anyone can think of. There are more features in the new smartphone than you can wiggle your finger at, especially in terms of biometric security. One of them is Samsung's new facial recognition where the password to unlock your device is your face. It took a little longer than normal for the S8 to register the photo, but it worked. If a facial recognition feature can accurately distinguish between individuals, the next test is usually the one for image depth, as not be fooled by 2D images. Both the phones have a 4 GB of RAM and 64 GB of storage on board.
"Facial recognition is a convenient action to open your phone - similar to the "swipe to unlock" action" said a Samsung spokesperson in a statement sent to Business Insider.More news: I ruined Trump's 'unbelievably successful couple of weeks' - Sean Spicer
The Galaxy S8 is finally official, and I have to say it's an unbelievable device. But the first of the measures on that list - the facial recognition system - has been shown to be less than secure. It's so accurate that it can even tell identical twins apart. It takes a couple of times to get it right, but the video, which was earlier reported on by SamMobile, suggests the Galaxy S8's facial-recognition feature can be rather easily duped.
Besides, who would want to use the fingerprint scanner when the there is an iris scanner in place? The fingerprint sensor is on the back of the phones and there is Iris scanning available to unlock the phones through the eyes scanning.
