Biometrics is an identification technology widely used in physical access control and forensics. Cryptography is the science for information security. People generally agreed that biometric information needs to be protected with cryptography. Many researchers also believe that biometrics can enhance the security of cryptography. In this paper, the author have surveyed recent developments on applying biometrics in cryptography, focusing on binding and generating a cryptographic key. The security of these proposals is briefly analyzed. Additionally, the author have reviewed some other developments, such as matching without removing chaff points, encrypted templates matching, symmetric hashing, and biometric random number generation.
