The advantages of digital media have opened up many new possibilities to hide data (information) within audio, image and video files. In order to provide copyright protection digital watermarking has been proposed as a means of identifying the owner or distributor of digital data. Data hiding and watermarking research builds on ideas and concepts developed in cryptography, communications theory, algorithm design, and signal processing. The data hiding problem is inherently more difficult than any of the problems that have traditionally been addressed in these fields. All data hiding algorithms combine and extend, in a sense, many of the solutions developed in these areas
