8-Valent Fuzzy Logic for Iris Recognition and Biometry

This paper shows that maintaining logical consistency of an iris recognition system is a matter of finding a suitable partitioning of the input space in enrollable and unenrollable pairs by negotiating the user comfort and the safety of the biometric system. In other words, consistent enrollment is mandatory in order to preserve system consistency. A fuzzy 3valent disambiguated model of iris recognition is proposed and analyzed in terms of completeness, consistency, user comfort and biometric safety. It is also shown here that the fuzzy 3valent model of iris recognition is hosted by an 8valent Boolean algebra of modulo 8 integers that represents the computational formalization in which a biometric system can achieve the artificial understanding of iris recognition in a logically consistent manner.
