Biometric data relating to a biological part are processed by obtaining, on the one hand, a first set of transformed biometric data (f(B1)) by applying at least one irreversible transformation to a first set of biometric data (B1), and, on the other hand, a second set of transformed biometric data (f(B2)) by applying said transformation to a second set of biometric data (B2). Thereafter, a decision is made as to whether the second biometric data set corresponds to the first biometric data set on the basis of a comparison between the first transformed biometric data set and the second transformed biometric data set, said comparison being performed at the bit level of a digital representation of said first and second transformed biometric data sets as a function of an error corrector code word. |
