Abstract: Image steganography based on various methods like LSB method of hiding data image to cover images are most common method for secret communication. There are many steg-analysis algorithms available for to detect hidden data in an image. There are many existing cryptography methods for image encryption like DES, AES, RSA, etc. but these are of less security on attack. In order to overcome these above mentioned drawbacks a novel chaotic map algorithm has been introduced for image encryption and further proceeded with PPM (Pixel Pattern Mapping) algorithm for image hiding. The algorithm computes chaotic encryption method on RGB planes of the image to be hidden then is followed by PPM based image hiding method on cover image. Our method includes RGB image for encryption instead of gray scale image as in state-of-art methods.
