A survey on image encryption techniques

Information security plays an important role when confidential information is transferred between two or more parties. There are two approaches i.e. Cryptography and Steganography which are used to tackle security issues. In cryptography technique, information is stored and transmitted in a particular form in such a way that only intended user can read and process it but does not hide the existence of information. On the other hand Steganography basically conceals the existence of the information in such a way that other person except sender and receiver donot know about transfer of information. In steganography the confidential information is concealed in some other way that the confidential information is undistinguishable. In this paper a survey is done based on the existing techniques.
