A Simple Scheme for Constructing Fault-Tolerant Passwords from Biometric Data

We present a simple combinatorial construction for the mapping of the biometric vectors to short strings, called the passwords. A verifier has to decide whether a given vector can be considered as a corrupted version of the original biometric vector whose password is known or not. The evaluations of the compression factor, the false rejection/acceptance rates, are derived, and an illustration of a possible implementation of the verification algorithm for the DNA data is presented.
