A hybrid approach of data encryption and steganography is used in our work. Motivation behind this approach is to provide a simple and smart image steganographic technique which must be capable enough to provide good quality stego-image. Image steganography is a technique in which pixel intensities are used to hide the data. In this approach, the secret information is initially encrypted and then encrypted bits are embedded into an image. Logistic chaotic maps are used for Image Encryption, and
