Recent techniques based on error-correction enable the derivation of a secret key for the (varying) measured biometric data. Such techniques are opening the way towards broader uses of biometrics for security, beyond identification. In this paper, we propose a method based on fingerprints to associate, and further retrieve, a committed value which can be used as a secret for security applications. Unlike previous work, this method uses a stable and ordered representation of biometric data, which makes it of practical use.
