SOLUTION: When a biological reaction detecting part 7 detects a biological reaction, iris data for authentication registered in an iris database 3 is collated with the detection result of an iris detecting part 1. When the detecting part 7 does not detect the biological reaction, processed iris data registered in a processed iris database 5 are collated with the detection result of the iris detecting part 1.
