Hi Everyone,
Welcome To Yet Another Episode of Tech Wednesday !

After iPhone X came with FaceID, it become a trend in every smartphone to give Face Unlock feature in their smartphones regardless of the price bracket (budget, mid or flagship). At present we have three types of Face Unlocks in the market:
  • Front Camera Based Face Recognition (using minimal or no algos)
  • Front Camera + AI / IR Technology Used (maybe both together)
  • 3D Face Recognition

According To Kaspersky Labs,
An inexpensive phone’s facial recognition relies on just the front-facing camera and some not-so-advanced algorithms. But a regular 2D camera without an IR sensor or dot projector can be easily fooled by photos snagged from a social media profile and printed on paper or shown on a screen

The Working:

OEMs have admitted to the fact that a normal face recognition is less secure than other methods hence they run a disclaimer when setting up face unlock.

The Resolution ?
Companies have taken this into consideration and have updated their face unlock tool. Samsung has implied Iris Scanning to the face unlock making it more secure, naming it "Intelligent Scanning". Xiaomi also uses AI for enhacing the scanning capabilities. But, when considering the "face-unlock" present in the budget phones, its the same use of cameras and 2D scanning making it least / no secure.


Do You Think Camera Based Face Unlock Is Useful ?

Nop, Camera based Face unlock feature will be harmful, as a full size picture of my face will be enough to unlock my phone, without bothering me...

Nope. Not with the new techniques. On the redmi note 6 Pro for example you can't use face unlock with a picture
