Abstract

An image hiding scheme in a 2-dimensional coupled map lattice of matrices is presented in this paper. Scalar variables at each node of the lattice are replaced by nilpotent matrices. The spatiotemporal divergence process is employed to hide the secret digital image in the state map of the nodal variables. The presented image hiding scheme does not require the computation of the difference image between two patterns produced by the perturbed and the unperturbed initial conditions. Computational experiments are used to demonstrate the efficacy of the presented technique.
