In the field of digital and multimedia applications, more multimedia data are developed and transmitted in art, entertainment, advertising, commercial areas, education and training through the networks, which may have important information that should not be accessed by the unauthorized persons. Therefore issue of protecting the confidentiality, integrity, security, privacy as well as the authenticity of images has become an important issue for communication and storage of images. In this paper an efficient method for image encryption based on Rubik's cube principle with chaotic Baker map is presented. It consists of two layers. The first layer is a preprocessing layer used to improve the security of the system which is implemented with the chaotic baker map. In the second layer, the Rubik's cube principle is utilized. The original image is first converted in to baker mapped image and then Rubik's cube principle is applied. The proposed technique will enhance the security level of the Rubik's cube encryption technique.
