Although people who already have an iPhone or iPad with face recognition can be reluctant to use Touch ID, Apple's fingerprint recognition technology still has many fans. Apple's latest patents offer the possibility that the iPhone will combine the two biometric technologies with the future.
According to foreign media Patently Apple, the Apple patent, published by the European Patent Office, says that the use of electronic devices to implement biometric authentication is often cumbersome. Some existing technologies, such as those for face recognition, require users to nearly perfectly align biometrics in the same manner during each iteration of registration and authentication.
Deviations from biometrics often lead to erroneous results. Therefore, the user may need to perform unnecessary multiple biometric verifications, or may not be encouraged to use biometric verification. That's why Apple chose to use the TrueDepth camera system instead of using 3D imaging to recognize faces.
This patent does increase the possibility of applying Face ID and Touch ID to the same device. The above figure shows that the device first tries Face ID. After face recognition fails, the Touch ID can be used instead. In addition, the user can choose to use the password.
It should be mentioned that the patented image uses an iPhone with a Home button, but Apple often uses images from older models to illustrate the principle. Considering that the current iPhone has removed the Home button, if Apple really intends to launch an iPhone model that supports both Face ID and Touch ID, it is almost certain that the Touch ID will be embedded in the display.
The patent also mentions that face recognition technology can be used with smart watches. Of course, the current Apple Watch doesn't carry any type of camera, let alone the TrueDepth system needed for Face ID face recognition.
