We present an application of the wire-tap channel to biometrics. Our contribution is threefold. We start with an information-theoretic approach and modelization of the biometric identification problem of the European Project (VIPBOB). Next, we generalize Wyner's coset-coding scheme and prove that linear codes achieves the Shannon-capacity. Finally, we present a solution to the original problem using LDPC codes.
