Steganography is an ancient technique of data hiding. Steganography is a technique in which secret data is hidden into vessel image without any suspicion. Most of the traditional approaches are achieving limited data hiding. To expand the information covering up proposed mechanism uses various techniques. Proposed mechanism is increasing the info disappearing ability and also provides high imperceptibility towards steganalysis. The key goal connected with steganography is usually providing the protection for hidden information from adversary. The integrity and confidentiality of the electronic information offers occur underneath immense hazard. Steganography will be the art along with technology associated with coated composing. Steganography utilizes text, pictures, audio tracks, video etc. as being a protect moderate. The proposed mechanism is based on image steganography technique. It is implemented based on the Canny Edge Detection. Pixel positions of edges in conjunction with Chaotic Cat Mapping [10] are used for the steganography technique. Proposed mechanism is using edge adaptive image steganography [3] by combining the benefits of matrix encoding and LSBM [8,9].
