Combining Crypto with Biometrics: A New Human-Security Interface
I present my research on combining cryptography and iris biometrics. This is work with Ross Anderson and John Daugman. It is a short talk so I will leave out the technical detail.
The motivation of the research is to incorporate advanced biometric authentication features into cryptography. We find that cryptography lacks the involvement of a human factor. In authentication, you would use a password or a token, but there is no real human factor involved. We studied the iris biometric because it is one of the most reliable biometrics discovered so far. There are however certain issues with the iris biometric. First, it is fuzzy. Second, its storage is quite controversial for privacy reasons. And third, it cannot be kept secret by its very nature. These limitations apply to biometrics in general.
