چکیده مقاله:

 

In this article, a new image steganography method has been proposed. The main emphasis of this technique is on the use of chaotic maps to design systems for having a secure and robust steganography. One of the main characteristics of chaotic maps that make them suitable for steganography systems is sensitivity to initial values. By utilizing the chaotic maps, the advancement of steganography security has been easily made possible. The proposed method is presented for images and it is based on spatial domain, as well. In this method, the watermark is first encrypted by the use of Chen chaotic equation and covered in a chaotic map. Then, embedding will be done in LSB"s1 of host signal. Finally, we evaluate the robustness of our method against attacks and its performance compared with some existing methods. The comparison results indicate that our proposed method is highly robust and obviously shows a good performance in comparison with other existing methods.
