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.
Claims20
A verification system, which verifies data input by a user against registered data to perform individual authentication, comprising:
- an input unit for inputting data of said user;
- a storage unit for storing said registered data;
- and
- a processing unit for executing a verification program that reads said registered data from said storage unit and verifies said registered data against said input data,
- wherein said storage unit installs a check program which checks said verification program and loads said check program into said processing unit,
- and said processing unit executes load said check program to check for alteration of said verification program.
A program check method for a verification system, which verifies data input by a user against registered data and performs individual authentication, comprising the steps of:
- reading a check program from a storage unit which stores said registered data into a processing unit, said processing unit executes a verification program that reads said registered data from said storage unit and performs verification with said input data;
- and
- executing said check program, to check for alteration of said verification program in said processing unit.
