Abstract
An iris authentication apparatus performs authentication based on data generated from a human iris in which camera section and a signal processing section detect an iris state in the form of data. By using a database section, an iris data processing section detects whether the iris state is in a living body state. When the iris data processing section has detected that the iris state is in a living body state, it is judged that the detected data is effective. In this manner, the iris authentication apparatus can reliably prevent a third person from being authenticated by pretending to be a registered person by forging an iris pattern that is a non-living-body iris.
