Secure Transmission of Biometric Scan Images Using Data Encryption Standards(DES) Algorithm

Biometric Scan Images, however, is vulnerable to unauthorized access while in storage and during transmission over a network. Unauthorized user can make a fake copy from image file from memory device or computer. Biometric Data in form of images are very confidential information of user. If they are in unauthorized hand then misuse of data may be harmful to authorized user. As in case of Unique ID each and every citizen of country have their Biometric scan images of finger, face and thumb and Iris all in original form like JPEG,JPG,GIF,PNG,BMP etc. To protect them from unauthorized access we can encrypt images so they can’t be detected and used. Protection is required at very initial 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 pixels in image. Digitized pixels will have a group of data bits and each pixels or set of pixels will be encrypted using DES algorithm. The whole Programming and design can be done in any platform like MATLAB, C, C++, Xilinx ISE 13.4 Software. The advantage of using Xilinx is that in this platform we can design a Layout of it so that finally a Chip level Solution can be provided.
