What happens if you reset your face ID?
"Face ID (Face Idy)" is a facial authentication technique that can complete the user authentication just by exposing your face in front of the iPhone.The point is that it is faster than the Touch ID of the fingerprint authentication, the incorrect recognition rate is lower and it is difficult to make a mistake.Because the "face path" is effective, it can be used immediately by people who are unfamiliar with the operation of the iPhone.
The Face ID improves the accuracy of face authentication by machine learning.The user's face is recognized by irradiating infrared rays from the "TrueDepth camera" at the top of the display, measuring the time until the light reflects and returning, but it is not so clever once.By repeating measurements, data is accumulated, and the pattern lurking there is enhanced to increase recognition accuracy.
The Face ID is learned every time it works, so it can respond to subtle changes in the face.After a certain number of days, it will not be affected by the parts that change slowly like a mustache, as well as the presence or absence of glasses and makeup before and after.If you wear a mask -shaped (large) mask that covers most of the face, the recognition rate will decrease significantly, but there are reports that it will be recognized if you repeat it many times, so the effect of machine learning is.It can be said that it is big.
"Reset Face ID" is nothing more than eliminating its learning results.In order to use the Face ID again, the face measurement must be performed, and the data on machine learning is lost, so the accuracy of face authentication is reduced.You should not do it unless your appearance has changed dramatically or if your face is no longer recognized.
If you want to reset, it is better to remove the other face data on the face you are currently recognizing.Open the screen in the order of "Settings" → "Face ID and Passcode" and tap "Set up another appearance" to make the iPhone remember.
