Abstract :

The increasing development of data transfer through internet made it easier to send the data accurate and fast to the destination. There are many transmission mediums to transfer the data to destination like e-mails; at the same time it is easier to modify and misuse the valuable information through hacking. So, in order to transfer the data securely to the destination without any changes, there are many approaches like Cryptography and Steganography. This paper deals with the image encryption as well as with the audio watermarking and Steganography. A review of various papers referred is given in brief. The outstanding progress of digital technology has increased the ease with which digital data is produced again and transmitted. However, since the advantages of such a progress are broadly available, they offer increasing potential to legal and unauthorized data manipulation. Consequently, the necessity arises to protect of digital media against unauthorized recording attempts, knows as data piracy. Current research in image, audio and visual copyright protection exploits the fact that the human visual perception and auditory system cannot detect small changes in some temporal or frequency domains of the image and the audio signal, respectively. This property is called masking, according to which a light but perceptible signal becomes non-perceptible in the presence of another one under certain conditions.
