Exploiting Modification Direction (EMD) is a technique to hide secret data into digital images. This paper reviews different EMD techniques to hide the confidential data. The main idea of EMD is to embed secret data into digital image in such a way that it provides high embedding efficiency as compared to the other techniques. The brief introduction of various EMD schemes and their comparisons are presented in this paper.
