A domain-flexible and selective image encryption scheme based on genetic algorithm, non-linear chaotic map, square-wave diffusion and orthogonal polynomials transformation is proposed. Extensive experiments were used to demonstrate efficiency and practicality.

A new selective image encryption technique based on hyperchaos, random artificial image, orthogonal polynomials transformation and dynamic permutation matrix using Lower Upper (LU) Decomposition is proposed, that outperforms existing approaches.
