Abstract

This paper presents feature vector based fuzzy vault method for cryptographic key generation from fingerprint data. The proposed method not only outputs high entropy keys, but also conceals the original biometric data such that it is impossible to recover the biometric data even when the stored information in the system is open to an attacker. Simulated results have demonstrated that constructed Fuzzy Vault Crypto Biometric Key Based on Fingerprint Vector Features addresses a replacement of minutiae fingerprint vault representation, where the vector features are used to form the lock set. The size of the fuzzy vault and the degree of the underlying polynomial are needed for reaching the reliable investigated binded key. This results in a high unlocking complexity for attackers with an acceptable unlocking accuracy for the legal users.
