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 that in operation, performs an individual authentication, wherein the individual authentication includes at least the following step (i) and step (ii): step (i) determining whether the target is a living body or not based on the second light, and step (ii) performing a biometric authentication of the target.
Claims11
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
- a circuit that 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
- performs an individual authentication based on the determination whether the target is a living body and result of the biometric authentication.
A method comprising:
- causing a light source to project dots onto a target, the dots being formed by first light;
- causing a first photodetector to detect second light resulting from the projection of the dots onto the target;
- determining whether the target is a living body or not based on the second light;
- performing a biometric authentication of the target;
- and
- performing an individual authentication based on the determination whether the target is a living body and result of the biometric authentication.
