Review on Steganography in Digital Media

Barnali Gupta Banik, Samir K. Bandyopadhyay

Abstract: Generally, in steganography, the actual information is not maintained in its original format and thereby it is converted into an alternative equivalent multimedia file like image, video or audio which in turn is being hidden within another object. This apparent message (known as cover text in usual terms) is sent through the network to the recipient, where the actual message is separated from it.
