These days, the entire world will be digitalized in all the ways. Each Business units, government offices, and military fields, research associations are utilizing the digitized image as exchanging mode for each basic information. These images usually contain either confidential or private information. During image transmissions, these highly confidential data can be manipulated by an unintended or unauthorized person, thus leading to insecurity for its sender. Therefore, it is essential to secure image. To solve this problem, many techniques have been proposed, in which data hiding and image encryption are the two main security techniques. This paper, we discuss the basic image security techniques, like Steganography Based Approach, cryptographic Algorithm Based Approach, visual cryptography based approach. This paper gives the future extent of Image security.
