Abstract

We demonstrate a possible application of “steganography” in a reaction-diffusion (RD) cellular automata (CA) model toward digital hardware (HW) implementation. Steganography is one of data-hiding techniques which conceal hidden data transmitted between the sender and receiver. Recently, a new steganography algorithm based on self-organizing patterns which are generated by a prey-predator model was proposed. However, this model has rich nonlinearity which complicates the HW implementation. Therefore, in this paper, we demonstrate numerical simulations of the RD steganography using the RD CA model which has simple dynamics and generates striped or spotted patterns. Obtained results indicate that the RD CA model is suitable for HW implementation of RD steganography.
