ABSTRACT
With the growing popularity of digital Medias through the World Wide Web, intellectual property needs copyright protection, prevention of illegal copying and verification of content integrity. The new data hiding techniques need to be developed that satisfy the requirements of imperceptibility, robustness, capacity, or data hiding rate and security of the hidden data etc. At this stage, water marking plays the role of an efficient tool.
