摘要：People generally save pictures in mobile phones or transmit to one another using several mobile applications. However, privacy of such images and pictures are of some importance to many people. Generally, for common people the threat to the privacy of the pictures may be very low; however, people prefer to have a certain level of security. In this paper, a simple encryption technique, based on two-dimensional cellular automata has been proposed. The local neighborhood pixel values of an image are used as part of the encryption key to encrypt the image, based on certain cellular automata rules. The quality of encryption technique and Peak Signal to Noise Ratio has been calculated and reported in this paper. A hardware architecture has been proposed to implement the scheme in mobile phones.
