Facial recognition works using faceprints which are unique just like fingerprints; it’s essentially biometric identification. Privacy is at stake, and both Google and Facebook have faced lawsuits over it.
Your phone can track your face and unlock almost instantaneously.
You don’t need to place your finger on the device to use it. No gloves need to be taken off, no worry about the right positioning of your finger, and no smudges need to be buffed off.
When driving or doing something crucial, this can save a deal of time and effort.
Your gestures can help you make payments, no need to manually enter the pin every time.
It’s more secure than the fingerprint unlocking system since it uses a far larger number of “data touch points” which means – to hack it, you need to work harder to identify all the touch points.
It makes the use of infrared systems, retinal scanning, and forward-facing 3D sensors and can unlock a phone within less than a few hundred milliseconds, irrespective of the position of the phone.
The feature works well even when it’s dark outside.
It can help identify defaulters, criminals or terrorists, missing children, minimize the cheating during voting, etc.
Facial recognition itself may be less mesmerizing but what we will be able to do by linking it with other features is breathtaking.
Security is a major concern, yes — but the chance of someone else unlocking your phone with Face ID is one in a million, compared with one in 50,000 for Touch ID.
