Bio metric Scan Images, however, is vulnerable to unauthorized access while in storage and during transmission over a network. Unauthorized user can make a fake copy fro m image file fro m memory device o r co mputer. Bio metric Data in form of images are very confidential informat ion of user. If they are in unauthorized hand then misuse of data may be harmful to authorized user. As in case of Un ique ID each and every citizen of country have their Bio metric scan images of finger, face and thumb and Iris all in original form like JPEG,JPG,GIF,PNG,BMP etc. To protect them fro m unauthorized access we can encrypt images so they can't be detected and used. Protection is required at very init ial end so that images can be directly saved in form of encrypted image in memory device. First image will be converted into pixels. Each pixel will be converted into DataStream and stored in codebook in same order as of p ixels in image. Digitized p ixels will have a group of data bits and each pixels or set of pixels will be encrypted using DES algorith m. The whole Programming and design can be done in any platfo rm like MATLA B, C, C++, Xilin x ISE 13.4 Soft ware. The advantage of using Xilin x is that in this platform we can design a Layout of it so that finally a Ch ip level So lution can be provided.
