Abstract
The present invention relates to a method of identifying a user, the method being implemented by means of a database containing personal data of users and containing for each user at least one unmodified biometric characteristic (E1,i), at least one biometric characteristic (E2,i) that has been modified and that is accessible from the unmodified biometric characteristic, and at least one item of identification data (D) that is accessible from a code identifying the modification that has implemented on the second biometric characteristic. The method comprises the steps of comparing first and second biometric characteristics (e1,i) read from the user with the characteristics in the database in order to determine (5) what modification has been implemented and to deduce therefrom the code identifying the modification; and extracting (6) the identification data by means of the code as deduced in this way. The invention also provides a database for implementing the method.
