The preliminary results shows that bio metric arrangement, including iris and users attributes, produced by different understanding methods can be balanced through the basic rays in their convex polyhedral cones and that templates protected by a method continued from Iris-arrangement can be collapsed into.These experimental results indicate that, without a thorough security study, convex polyhedral cone arrangement cannot be simulated secure. In this paper, The presence of a contact lens, particularly a face cosmetic lens, poses a challenge to iris understanding as it obfuscates the common iris models.Many types and colors of lenses are accessible from a number of disparate manufacturers. To consider the effect of these frameworks on iris understanding. The proposed approach outperforms other lens detection algorithms on the improved iris understanding performance.Detection of the presence of a contact lens is the first step to improving the use of iris understanding for contact lens wearers.The extraordinary market success of Iris-templates relies thickly on its computational advantages, including consumption speed for large-scale identification and automatic brink improvement based on image quality different methods modified from Iris-arrangement were proposed for iris and user attributes based understanding.
