Iris Biometric Cryptosystems. . The majority of biometric cryptosystems require the storage of biometric-dependent public information applied to retrieve or generate keys which is referred to as helper data . Due to biometric variance it is not feasible for most biometric characteristics to extract cryptographic keys directly.

Experiments on Biometric ComparatorsInvestigated issues comprise the accuracy of each comparator, computational requirements compared to the baseline technique using HD with applied bit-shifting to account for rotational alignment, as well as related questions. More specifically, the distribution of reliable bits or trade-offs between recognition accuracy and speed is evaluated.
