This paper presents an efficient image encryption scheme based on chaotic systems and singular value decomposition. In this scheme, the image pixel's positions are scrambled using chaotic systems with variable control parameters. To further enforce the security, the pixel gray values are modified using a combination between singular value decomposition (SVD) and chaotic polynomial map. Simulation results justify the feasibility of the proposed scheme in image encryption purpose.
