GENETIC ALGORITHM BASED STEGANOGRAPHY USING ADAPTIVE RECTANGULAR EMBEDDING AREA

Image steganography is to hide an image inside an image for security purpose. Different approaches were applied for image steganography some of them are based on spatial domain and others are based on frequency domain. Spatial domain steganography approaches are simpler because they do not involve applying any transformation to the image. In this article, genetic algorithm is presented for searching for the best locations to hide the image bits inside the image. The image can be embedded in an adaptive block inside the host image. Furthermore, the secret bits can be reserved and inverted before embedding in order to optimize the hiding performance measures. Results show superiority over the baseline approach with respect to all evaluation measures
