Nowadays, security and privacy has become one of the primary issues in data storage and transmission. In the age of multimedia, images are widely used in business, advertising and promotions. Therefore the protection of images from unauthorized access is important. Image encryption plays a significant role in the field of information hiding. In this article, we introduce a chaos based image encryption technique using method of shuffled operations. This technique uses 128-bit private key for encryption. Performance of proposed image encryption scheme is compared with the existing inter pixel displacement image encryption scheme. Performance evaluation reveals that proposed scheme performs better than existing scheme in terms of entropy of encrypted image.
