Image based communication is increasing day by day. There are several area where image based communication have been used widely like website, university database, hospital etc. So there is the need of proper security in case of image data so that unauthorized access can be prevented and detected timely. This paper main aim is to find out the pros and cons in the area of image security so that the gaps will be highlighted. It also elaborates the methods which are applied in this area and the suggestions provided. It includes the latest cryptography algorithm for the discussion and analysis. Based on the gaps and suggestion future framework can be developed for the better security of images.
