Facial recognition has been about for quite a while.
The biggest users have been casinos. If you’ve been caught cheating, or counting cards, your photo is shared amongst all the casinos, and as soon. As you go to step inside, it’ll recognise you, and warn security.
Also security services have used for years, for the obvious reasons.
Yet some how, your phone rejects you, unless you do the pose you did the day you set it up. I usually end up entering my pin, or fingerprint… Due to some daft sod at Samsung decided to stick it at the back, and furthest away from the right… This hardest to reach. Of course when set up, you place your fingertips in several different ways to try to cover the whole finger, but yet again… Not quite… Oops enter pin!
Sony had the right idea, and out the fingerprint scanner in the on/off button. Which of course you use everytime you turn the screen on.
The idea, I love. Yet phones haven’t quite got it. They use a photo, rather than science to recognise you, same with iris scanners.
(Yes I know it’s fiction) even CSI showed that facial recognition is done by a few measurements, which if done correctly will ID you behind a balaclava.
