Abstract:
This study focuses on image shuffling where the image is segmentd into four and then to each segment, various shuffling algorithms are applied and iterated until the vertical, horizontal and diagonal correlation values are minimum. Then to the shuffled segment, Cipher Block Chaining (CBC) algorithm is applied. Then the same procedure is applied for all the four segments and then combined again to form the original shuffled image. To authenticate the proposed method, correlation values, Number of Pixels Changing Rate (NPCR) and the Unified Averaged Changing Intensity (UACI) histogram analysis are computed to validate the sterness of the proposed algorithm and compared with the available literature.
