Scramble Image Based on LFBSR (Linear Feedback Shift Registers)


One way of security is Image Scrambling. Scramble in general mean, scattering all elements in a random ways. Scatter the pixels of any image in the way that which can’t recognize the image, that is called “Image Scramble”. There are many types of image scrambling. The proposed method in this paper deals with a series of shift registers and using XOR gates. The scrambled image having good security by using many tests of the results. The proposed algorithm can applied to the images in a real-time applications, and the implementation is easily done.
