Due to the strong linkage between an individual and a claimed identity, biometric authentication is widely used to authenticate an individuals identity by matching an individuals biometric with a database of records. Yet, if the biometric template stored inside the database is compromised, invasion of user privacy is inevitable. For instance, a fingerprint image can be reconstructed with high accuracy using existing technologies if the corresponding set of fingerprint minutia is revealed to an adversary. In this paper, we first enhance the performance of original polar grid-based 3-tuple quantization by considering polar coordinate that only covers partial image of fingerprint. We then enhance the modified polar grid-based 3-tuple quantization with random bits toggling technique to protect fingerprint minutiae template. The promising experimental results on FVC2002 DB1 and DB2 justify the feasibility of the proposed method.
