Method for secure biometric authentication/identification, biometric data input module and verification module
First Claim
Patent Images
1. A secure biometric authentication method including communication of biometric data enciphered by at least one biometric data input module not holding a secret key to a verification module, the method comprising the steps of:
- for the biometric data input module;
inputting data of a user,concatenating to the data a diversification value,enciphering the concatenated data,transmitting the enciphered data to the verification module; and
for the verification module;
deciphering the received data by a sole secret key to verify that the diversification value has been taken into account in the enciphering,wherein a separate diversification value is generated by the verification module and communicated to the biometric data input module.

Abstract
A secure biometric authentication method, comprising communication of biometric data to a verification module. The invention is characterized in that it consists in encrypting the biometric data with a cryptographic algorithm and in introducing for each cryptographic operation carried out a different diversification value.
