Abstract
In a verification system which verifies individual input data against registered data to perform individual authentication, the verification program is checked for alteration. Programs for verification in a processing unit are checked for alteration by a check program in the tamper-proof environment of a lower-level storage unit. Hence illicit use of the verification system through program alteration can be prevented.
