Abstract
With digital India popularity, organizations are proposing numerous frameworks focusing on digital encryption techniques. Due to the ease of copying, editing, and tampering of digital documents and images has led to encrypting the information mandatory for transmission and storage. It evident that the correlation between the image pixels to its neighborhood region is high, reducing correlation between the pixels value makes it difficult to guess for the original image and thus improve the security. In this paper, we introduce a novel image encryption method which initially rearranges the image on the basis of switching gray codes and pixel explosion. The pixel explosion uses well-defined key that switches between the gray-code of the image pixels. Experimental results would show that the proposed pixel explosion is enough for partial encryption and enhances security of the data. Further, it could also support as an armament for any existing algorithm.
