An Efficient Biocryptosystem Based on the Iris Biometrics

A new and efficient method for combining iris biometrics with custom cryptographic schemes to obtain an efficient biocryptosystem is proposed in this paper. Though the method structure is basically derived from a previously described biocryptosystem scheme, the introduction of new image processing methods alongside with efficient utilization of traditional methods show promising developments compared with the previous biocryposystem especially in the field of generating longer cryptographic key strings while keeping the system quality.
