Friends, in today’s modern era, smartphones have become an important part of our lives, which make many of our tasks easier, today phones are becoming more smart and secure. One of the most advanced security features available today is Face ID on the iPhone. This system created by Apple uses advanced sensors and artificial intelligence to accurately recognize your face and protect your data. Let us know how you can use it-

1. TrueDepth Camera System

Face ID works through a special TrueDepth camera system located on the front of the iPhone. This system is specially designed to detect and analyze facial features.

2. Thousands of infrared dots create a 3D map

This system projects thousands of invisible infrared dots onto your face. These dots help the phone create a detailed 3D map of your facial structure.

3. Infrared camera reads depth and texture

An infrared camera scans these dots and analyzes the depth, contour and texture of your face. This makes the identification process very accurate.

4. Data stored safely inside the phone

All facial data collected is stored in a secure enclave inside the device. This means your face data stays on your phone and isn’t shared anywhere else.

5. Not just photos — it detects real faces

Face ID doesn’t just rely on photos. It checks depth, movement and real-time details of the face, making it difficult to cheat the image.

6. Works even in low light or darkness

Because Face ID uses infrared technology, it can recognize your face even in low light or complete darkness.

7. Adapts to changes in your appearance

The system intelligently learns from changes over time, such as growing a beard, wearing glasses, or minor facial changes.

8. Can recognize upper part of face with mask

Face ID can recognize your eyes and the upper part of your face, allowing it to unlock even when wearing a mask (on supported settings).

9. Useful for many daily tasks

Face ID isn’t just for unlocking your phone. It’s also used for app security, payments, and password autofill, making everyday use faster and safer.

10. The chances of unlocking without permission are very less

According to Apple, Face ID has a very low chance of being unlocked by the wrong person, making it one of the most secure smartphone authentication systems.
