The last decades have seen a growing interest in hash func- tions that allow some sort of tolerance, e.g. for the purpose of biometric authentication. Among these, the syndrome fuzzy hashing construction allows to securely store biomet- ric data and to perform user authentication without the need of sharing any secret key. This paper analyzes such a model, showing that it offers a suitable protection against informa- tion leakage and several advantages with respect to similar solutions, like the fuzzy commitment scheme. The design and characterization of LDPC codes to be used for this pur- pose is also addressed.
