A new chaos steganography algorithm for hiding multimedia data

The paper is devoted to propose a new chaos steganography algorithm for hiding the multimedia data, image, text, or sound. The proposed algorithm based on coordinate the data in the image dimensions using chaos distribution arrangement. The data is embedded with the original image in the pixels least significant bits, so can´t appears within the image. When the image received the embedded data is separated and rearranged using the initial condition of the chaos coordination. The algorithm is implemented using Matlab program on three types of data, the first is image data, the second is a text data, and the third is sound signal data. The results show a good hiding for the tested data in the original images with high degree of security if steganalysis is performed on the composed original image.
