(Abstract)Biometric Encryption(BE) merges biometric template and the cryptographic key together to create biometric-key. Biometric template and the cryptographic key cannot be revealed without a successful biometric authentication. BE also includes cancelable biometrics, and with that, security and privacy can be achieved. The main schemes of BE are introduced in this paper and their advantages
