Verification system and program check method for verification system
摘要
<p>In a verification system which verifies individual input data against registered data to perform individual authentication, a verification program (32, 34) is checked for alteration. Programs for verification in a processing unit (3) are checked for alteration by a check program (20) in the tamper-proof environment of a lower-level storage unit (2). Hence illicit use of the verification system through program alteration can be prevented.</p>
