Stego with Color Cue

摘要

The ontogenesis of technology has paved way for an upsurge in cybercrime too. In fact, the rate at which this happens overheads even the Moore's law. Steganography is a tool which supports us in elucidating the above facts. Here, we have proposed four methodologies in image steganography. First method deals with gray image, and the subsequent methods encounter color image. Pixel indicator technique is used for selecting the plane of embedding for color images. Embedding is done in block segmentation fashion. We have devised a novel mod4 methodology which tells us about the order of embedding, number of bits to be embedded in each pixel as well as about indicator channel in PIT and also tremendously escalates the randomization. OPAP technique reduces error for an enhanced image quality. MSE, PSNR, and the brute-force attack values of the above proposed methodologies have been simulated and displayed.
