AI Tips: How does a phone unlock just by showing your face? Is AI also hidden behind Face ID?..
Phone Lock Technology: AI has taken four steps forward in the technological race. Now, AI's name is present in every device, from small to large. Almost everyone is using AI to complete their tasks, whether it's making calls or having it recite poetry, poems, or office work. Things have become much easier thanks to AI. But one small thing: how does a phone unlock just by showing your face? What technology is behind this?
Have you ever wondered how your phone unlocks magically just by looking at you? The magic lies behind this. Yes, AI is also behind your Face ID. Let's understand how this 'Face ID' works.
As soon as you look at your phone, your phone's camera activates. This isn't just a normal camera, but a smart camera that has been taught many things by AI.
Step 1: 'Where's your face, brother?' (Face Detection)
First, the AI looks at your phone screen. Like a detective, it searches for a 'face' on your screen. It knows certain key features of a human face, such as where the eyes, nose, and mouth are. So, it quickly creates a frame and says, "Gotcha! Found the face!"
Step 2: 'Feature Scan' (Feature Extraction)
Now, just finding a face isn't enough. The AI scans every minute detail of your face. For example, the shape of your eyes, the shape of your nose, the thickness of your lips, the curve of your jawline... all of these are like your 'facial fingerprints'. Every person's facial fingerprint is unique, just like your hand fingerprints.
Step 3: 'Recognize Who?' (Comparison & Match)
Once the AI has extracted all your facial 'fingerprints', it matches them with the facial 'fingerprints' stored in its database. If you set up Face ID when you first set up your phone, it will have saved a complete map of your face.
Now, the AI compares your current scanned face to that saved map. If everything matches, then... click! Your phone unlocks!
Step 4: 'Learn and Improve' (Continuous Learning)
You might think that's all? No! AI is a real 'bookworm'. It's constantly learning. If you wear glasses, or have a beard, or sometimes wear makeup, the AI gradually learns to recognize these new looks as well. The more you use Face ID, the better it learns to recognize you.
So, what's the bottom line?
Yes, absolutely! AI is behind your Face ID. This is all thanks to an AI technology called Computer Vision. Computer vision helps AI "see" and "understand" things, just like our eyes and brains do. So the next time your phone unlocks just by looking at you, know that AI has done its job. Amazing, isn't it? Now you too can say, "Face ID? Oh, that's just AI doing its thing."
