In this paper, a new method is represented which utilizes the chaotic properties of chaos function and image histogram. Considering each pixel gray scale, the image in this method is partitioned into 16 sections. The histogram of each section is used for the determination of those pixels which are nominated for the encryption of code data bits. The chaos function is responsible for the selection of an appropriate order among pixels which are chosen at the previous stage.

High embedding capacity, high value obtained for the image PSNR, and resistance of the proposed method against brute-force attack are the characteristics that emphasize high effectiveness of this method.
