Multiple Image Encryption Using Phase Manipulation and SCAN Methods

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 222)


In this paper we propose a new concept of combined image encryption using phase manipulation and SCAN methods. Entire encryption process involves two stages where multiple images to be encrypted are applied to phase manipulation block. In first stage Fourier Transform (FT) is applied to get phase and magnitude of all input images. Phase of all images are scrambled to get modified image after applying Inverse Fourier Transform. In second stage these modified images are scrambled by using SCAN method. SCAN method finally gives resultant encrypted image by rearranging the pixels positions of modified image. Experiment is conducted for dual and multiple images using MATLAB software. From the experiment we obtained highly scrambled image at the end of encryption process. Decryption process employs exactly reverse process of encryption which results in the reconstructed images.
