| How does Face ID work on iPhone and is it safe? |
Users' privacy is under serious threat these days. With big tech companies sinking, this information gathering benefits when ads are targeted to a user or even sold. But does it also apply to the faceprint function of the iPhone?
This function makes it possible to obtain a full 3D drawing of a human face. This way, you can use the data to unlock later only with the user's face.
This feature can be useful, but its ability to accurately access facial data has some users annoyed and worried. But it won't work like that
Face ID on iPhone
According to several sources, the iPhone's facial recognition feature does not pose a privacy risk. Mainly because Apple doesn't really need a picture of your face, but the functionality just relies on a series of numbers and arithmetic operations to work without saving your face picture.
When you start Face ID, your iPhone allocates 30,000 invisible points on the face on the original depth camera depending on this function.
Using a mathematical representation, the data derived from these points is converted into something similar to mathematical equations. It is very complex and there is no risk because it is not included.
The target data is stored in encrypted form on the phone. comme that Apple has repeatedly confirmed that the facial data used by Face ID will not be stored on your phone and will not be shared with anyone. Apple itself.
Since this data was encrypted, even if Apple mastered it, it would not be able to decipher its "mathematical representation".
How does Face ID work?
The Face Print feature on iPhone is very easy to use, yet very complicated to use. As already mentioned. When Face ID is used for the first time, the DeepSense camera displays 30,000 different points on the face.
And when you use the face pressure function to unlock the iPhone, the original depth camera will distribute the same points on the face. However, this time the technique compares the distribution of points with the first time. In the case of correspondence, the lock is open.
