REVIEW OF DIFFERENT METHODS OF PROTECTING PRIVACY USING FINGERPRINTS

In authentication systems, protecting the privacy o f the fingerprints becomes a very important issue. Traditional encryption is not sufficient for privacy protection of fingerprint because before t he fingerprint matching decryption is required, which exposes the fingerprint to the attacker. Therefore, in recent years, significant efforts have been put into developing specific protection techniques for fingerprint. In this paper various methods for recognizing fingerprint has been surveyed. We have introduced the idea of combining biometrics such that the combined biometric would not be a unique identifier of the person, yet it could still be successfully used for authentication purposes.
