Authentication of a user of a mobile electronic device by the use of 3D Facial Mapping

Current implementations of visual authentication, such as facial or retina recognition suffer from security vulnerabilities; they can be tricked to gain unauthorized access to a computer system.

Although, these technologies are already implemented in many consumer electronic devices, they have seen very little use due to their security vulnerabilities.

Existing camera based 2D facial authentication systems have vulnerabilities due to the following exemplary reasons:

  1. Displaying a photo or video playback can trick the system to authenticate unauthorized intruder;
  2. Subject to desirable environment lighting conditions, for example poor light conditions affect the facial recognition algorithms as it uses a camera system;
  3. Skin Altering facial makeup or hair/facial coverage affects the reliability of the system.

An alternative solution is to rely on 3D facial mapping for authenticating a user of a mobile electronic device. One example of such a system uses the speaker of the mobile electronic device to emit a high frequency sound wave, and also uses the microphone of the mobile electronic device to receive reflections of these sound waves. The mobile device may emit these waves in short bursts, and the frequency should ideally be a frequency outside the hearing range of humans.

A user can point the device towards their face, and the device may then receive an input to start the authentication meth...
