    Abstract: With the popularity of the Internet, image transmission has become easier than before, but the digitization of the image has also become highly vulnerable to tampering attacks over the public network. In this paper, we propose a chaos-based image authentication algorithm which generates an authentication code for each image block. Furthermore, the applications of image integrity are also investigated. Using the chaos-based authentication codes, which are embedded in the elaborately selected pixels, a verifier can protect rightful ownership and detect malicious manipulation of embedded images. The experimental results show that the quality of the embedded image can be highly preserved, and the parts that were tampered with can be correctly located.
