The Design of Fingerprint Vault Based IC Card Access Control System

摘要

Aiming at the practicability, security and dependability, a Fingerprint Vault based low consumption IC card access control system is presented in the paper. The Fingerprint Vault scheme is used to ensure the security of the fingerprint template. By taking advantage of the Fingerprint Vault scheme, which is developed based on Jules and Sudan's Fuzzy Vault scheme, our system does not store the user's fingerprint template in the IC card, but a secret K "locked" by his fingerprint. Only the user who owns the matching fingerprint can retrieve A: successfully and therefore validate his identity. It is computational infeasible for the attacker to obtain the user's fingerprint template from the data stored in the IC card. Comparing with the normal biometrics based access control system, our system can provide higher security. The overall design idea, the implementations of hardware and software of the system are presented in this paper.
