Abstract :
Recent years have seen more interest from researchers in image encryption using chaotic signals. A new method was proposed for image steganography in this article in which two chaotic signals for specifying the location of the different parts of the message in the picture. An 80-bit key was used to reach the preliminary measures of the two chaotic signals. One of the advantages of this method is its security which is caused by the chaotic signals and the higher range of the PSNR (42.06).
