A Two layer secure image encryption technique

The growing use of networking in almost every possible field, data transferring or data sharing has become an essential need. All kinds of users directly or indirectly involved in data transfer. But data transferring is susceptible to various risks i.e. hacking of potential data, tempering, etc. Various services based on data sharing or transferring across the network needs security and reliability of the system. Most of the stakeholders may not be fully aware about the fact that their communication is unsecure. Users are relying upon the system they are using and assume that their ongoing communication is secure. Generally, data categorized into text and image messages. There are many works on securing of text message through encryption has been achieved in last decades. But securing images are differs in many ways from that because text. Nowadays, securing image is necessary and quite in demand. In this paper, we have proposed an image encryption algorithm to secure image while being transmitted in two layers.
