Bio-cryptography: A Bridge between Biometrics and Cryptography

Passwords and tokens are commonly used for tools for traditional cryptography, but there are serious issues around them lost or stolen, and most importantly, when used, there is no differentiation between a genuine user and an attacker who uses the stolen password or token. Biometrics can solve some of the issues mentioned above by using physical characteristics to uniquely identify a genuine user, however, biometric systems also have their own vulnerabilities. This presentation will introduce an emerging technology named bio-cryptography. It acts as a bridge between biometrics and cryptography, and merges the advantages of both. The security level of a bio-cryptosystem is adjustable and the trouble of remembering a long password or carrying a token is avoided. In a bio-cryptosystem, a secret key is either technically bound with the biometric features or directly extracted from the biometric features.

Speaker: Dr Wencheng Yang

Wencheng Yang is a postdoctoral researcher at the Security Research Institute (SRI) at Edith Cowan University (ECU), Australia. He has several years’ research experience in the area of cyber security, especially biometric security and biometric pattern recognition. He has published several papers in high ranking journals and conferences, e.g., IEEE Transactions on Information Forensics and Security, and Pattern Recognition.
