- Abstract
In this paper, a content-based image verification scheme is presented. This scheme is suitable for verifying the integrity of images transmitted over insecure networks. The Discrete Cosine Transform is used to embed a block-based mark for each block in another block according to a specific algorithm. To achieve higher protection, the marked image is then encrypted using 2-D chaotic Baker map before being transmitted over the communication channel. The encrypted marked image is transmitted over a wireless Additive White Gaussian Noise (AWGN) channel without error correction codes. At the receiver side, a decryption process is performed, and the marks embedded in each block are extracted to detect suspicious forgery activities. Simulation results show the suitability of the proposed scheme for applications with sensitive data types such as military and nuclear applications.
