Summary:
We demonstrate a possible application of “steganography” in a reaction-diffusion (RD) cellular automata (CA) model. Steganography is one of the latest techniques that conceal some data (messages) in other data-like images. Recently, a secure communication algorithm based on self-organizing patterns generated by a prey-predator RD model was proposed [1, 2]. In contrast, we employ a simple CA model [3] for steganography applications instead of using the prey-predator RD model. The model generates Turing-like patterns, e.g., stripe and spot patterns observed in human fingerprints, marking patterns on animal skins, etc. This model has simple dynamics and generates stripe or spot patterns at its equilibrium within a few cycles, which implies that the model is suitable for hardware implementation for a steganography application. Through extensive numerical simulations, we demonstrate steganography using the RD CA model in which messages can be encoded and decoded while concealing the messages in communication channels.
