Secured Image Transmission Through Region-Based Steganography Using Chaotic Encryption

Information security is one of the challenging problems nowadays, and to solve this problem, a new algorithm which provides double layer security is proposed, by combining region-based steganography with chaotic encryption. Region-based steganography is the technique of protecting the hidden information in certain regions of interest, which is most efficient for data hiding. One of them is the edge region in image, which is most effective for data hiding. For encrypting data, we used CNN because of its random nature which is very challenging for hackers to know about the secret information. In the proposed work, the secret data are first encoded using CNN, and then, the scrambled message is embedded inside the edge region of cover image using matrix encoding scheme, which provides high security. The complete procedure is instigated in MATLAB, and the result analysis is given, which shows the strength of the technique.
