USER AUTHENTICATION METHOD OF BIOMETRIC AUTHENTICATION CARD CAPABLE OF DETERMINING AUTHENTICITY OF CARD USER AND PREVENTING UNAUTHORIZED USE OF CARD BY ENCRYPTING CARD INFORMATION BY USING UNIQUE BIOMETRIC INFORMATION OF CARD OWNER AND CRYPTOGRAPHIC BIOMETRIC HASH TECHNIQUE

摘要

The present invention relates to a biometric authentication card which prevents biometric information leakage of a card owner by determining authenticity of a card user when using a card by using unique biometric information of the card owner and cryptographic biometric hash (cancellable biometrics) technique. The present invention scans first biometric information of a card owner when registering the card owner, generates a first biometric hash value by using cryptographic biometric hash technique based on the first biometric information to store the same in an internal memory, scans second biometric information of a card user when using the card, generates a second biometric hash value based on the second biometric information, and authenticates whether the card owner and the card user are matched with each other by comparing the first biometric hash value with the second biometric hash value when authenticating a user.;COPYRIGHT KIPO 2018
