In modern era of digital world, exchange of information in form of image often very frequently over communication channel, the secrecy of multimedia data like images becomes very important, The issue of secrecy for image resolved In many digital applications such as sensitive visual aids, broadcasting, military services, rare satellites images and confidential medical images etc. To reduce the processing overhead with the concern of Real-time data transmission application, to reduce such a huge file processing cost, we needs to enhance our encryption/decryption techniques. This paper proposed a novel image encryption technique based on Hannon like chaotic map. Chaos-based image encryption technique is one of the more promising encryption algorithms that provide very efficient and fast way of image encryption due to its ubiquitous phenomenon in deterministic nonlinear systems that exhibit extreme sensitivity to initial condition and random like behaviours.

Keywords— Image RGB colour component, image encryption, Henon map, chaotic system.
