IMAGE ENCRYPTION USING ENHANCED FOUR STAGE ENCRYPTION

摘要

Secure communication for the information is very important role in digital era. There are several encryption techniques introduced to communicate the data from one location to the other. In digital communication, the images are encrypted using several techniques. In this paper, an encrypt scheme to encrypt bit map images is proposed using enhanced four stage encryption. Different analytic studies are performed on the images for finding the traces of the original image in the encrypted image. Comparative studies are performed on different encrypted images of the same image to trace back the original image. The results show that no patterns of the original image found in the encrypted image.
