A Steganography Scheme Based on Cyclic Codes with Iterative Toggle Search Set

摘要

This paper proposes a cyclic steganographic scheme based on cyclic codes for embedding secret message. This scheme is capable of achieving low complexity and fast embedding time. These are two attractive reasons for this method: first, embedding and secret message extraction can be implemented easily by employing shift registers with feedback connections, and second, because they are rich in coding structure, it is possible to devise various practical methods for decoding or extracting them. Moreover, this work has no need to find the maximum likelihood solution in terms of toggle sequence. Instead of full search method, iteration scheme is employed in this work.
