Steganography is arrangement of disguising one data into another data or in a couple of media for e.g. content, picture, sound, video etc.
The reason for a steganography is to shroud a lot of mystery information into a host media to such an extent that the concealed mystery information can be kept from the assault of undesirable users. In steganography, there are three things that are important first to increase hiding capacity, vitality to certain attacks and to increase the security. In Image steganography the mystery information is installed inside a picture has been broadly considered amid the most recent decade because of the cost diminishing of picture accumulating and correspondence and besides it can’t be detected by the human eyes. The host picture is alluded to as the first picture while the picture which is acquired by implanting mystery picture into cover picture without crushing the cover picture is named as stego picture. It is the method of concealing a message covertly into a cover media with no adjustments in the cover media so nobody can presume the media that any mystery data is available in it or not aside from the approved individual. It assumes a critical part in securing imperative data over unreliable correspondence channel by giving an envelope to the data. It is secure because after embedding the image in the host image the image doesn’t change and looks similar to that of host image.
