![]() ![]() ![]() Each offers challenges and solutions to these challenges are analyzed. Data hiding is implemented in two different media audio and image files. How steganography works is examined, keeping in mind Bender’s specifications. ![]() The history of steganography is briefly dealt with. In this paper, a detailed analysis of steganography is made. A person, group, or company can have a web page containing secret information meant for another. Thus, steganography has a double layer of protection: first, the file itself is hidden and second, the data in it is encrypted. Using encryption can identify the sender and the receiver. The advantage of steganography is that it can be used to secretly transmit messages without the fact of the transmission being discovered. hence, it is said to be the advanced cryptography. Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message this is in contrast to cryptography, where the existence of the message is clear, but the meaning is obscured. From the time of Herodotus in Greece, to the defense mechanisms of today, steganography has been used to deny one’s adversaries the knowledge of message traffic. Steganography, literally meaning “secret writing”, involves hiding a data file in another innocuous-looking file. ![]()
