Encryption is the process of encoding a text, image or file in order to secure it. In the world of social media, there is a vast growth in the online contents and the ways of communication. Online contents may be in various forms like text, image, audio, video etc. It is a need of the hour for several system developers to protect the user contents in any forms. There are various commonly used encryption algorithm used by researcher's for file security like DES, AES, Blowfish, Chaos Approach. Based on review of literature it is found that each of these algorithm is giving varying performance as context changes and there are some constraints observed among few of these algorithm.The proposed work aims at addressing few of the challenges as issues and constraint of existing methods by identifying problem areas and devising a solution. Based on the recent study, the primary focus of this work would be Chaos and AES. Actually it uses a modified chaos which has proved better in terms of results by creating high level of confusion while encrypting the file to be secured. So proposed system will try to contribute a better encryption for image security. Performance of the proposed algorithm will be evaluated using key sensitivity, algorithm complexity, histogram analysis.
