1. 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.
