Image steganography is taking a dominant position in the field of network security. Here an advanced slab-based image steganography technique has been proposed where searching domain to hide a secret message is increased by almost 98%. First a grayscale image is taken and resized with a desired size. Then slab-based image steganography technique with diagonal searching is applied. If no suitable row/column/diagonal has been found, then reverse searching operation is performed with all these row/column to form a completely new searching domain. It maximizes the probability to get exact match with the secret message. In this technique, cover image is slightly modified but gives promising results with respect to other existing techniques.
