Abstract
A system including a light source that, in operation, projects dots onto a target, the dots being formed by first light; a first photodetector that, in operation, detects second light resulting from the projection of the dots onto the target; and a circuit. The circuit, in operation, determines whether the target is a living body or not based on the second light, performs a biometric authentication of the target, and authenticates an individual, in response to a determination that the target is a living body and a result of the biometric authentication.
Claims8
A system comprising:
- a light source that, in operation, projects dots onto a target, the dots being formed by first light;
- a first photodetector that, in operation, detects second light resulting from the projection of the dots onto the target;
- and
