Abstract
Abstract: Steganography is an art and a science of communicating in a way, which hides the existence of thecommunication. It is also called as “covered writing”, because it uses a “cover” of a message for sending anyimportant secret message. In the steganographic scenario, the secret data is first concealed within anotherobject which is called “cover object”, to form “stego-object” and then this new object can be transmitted orsaved. Using different techniques, we can send secret data in the form of an image, a music file or even a videofile by embedding it into the carrier, forming a stego-signal. At the receiver’s end, the secret data can berecovered from the stego-signal using different algorithms. The main goal of Steganography is to communicatesecurely in a completely undetectable manner and to avoid drawing suspicion to the transmission of a hiddendata. It is not only prevents others from knowing the hidden information, but it also prevents others fromthinking that the information even exists. If a Steganography method causes someone to suspect there is secretinformation in a carrier medium, then the method has failed.
