Face ID vs. Face Unlock: Apple's Technology Leads the Way in Facial Recognition Security

Nowadays, most smartphones have the feature of unlocking the phone from the face. Apple calls it Face ID, while in Android phones it is commonly known as Face Unlock. The two features look similar, but there is a big difference in the technology behind them. That is why every Face Unlock system is not as secure as Apple's Face ID. Let me tell you that Apple's Face ID does not unlock the phone just by looking at the face from the phone's front camera. The TrueDepth camera system is used for this in the iPhone. It creates a 3D map of the face by projecting thousands of hidden infrared dots on the user's face. The infrared camera and other sensors in this system together recognize the depth of the face and the texture of different parts. Then the phone matches this information with the face data stored in a secure way. A big advantage of this is that the Face ID system can work even in low light or flash. It is not difficult to cheat every photo on the device.
