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, 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.
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;
- and
- performing an individual authentication that 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.
