Data Hiding remains one of the most challenging problems. In this paper a digital image hiding technology based on chaos map and image blending is proposed. Firstly, with chaos map, a hiding image is randomly scrambled. Secondly, the carrier image is divided into subblocks according to the size of the hiding image, each subblock corresponding to each pixel of scrambled image. Then with the digital image blending technology, the pixel of hiding image is blended into the subblock of carrier image. Chaos map and image blending technology are introduced to improve the imperceptibility, security and robustness of hiding image. Experimental results show the proposed technique has high robustness under image processing operations and good imperceptibility.
