Abstrakt	Digital watermarking techniques are based on information hiding techniques similar to steganographic approaches with the overall goal to embed information into a cover signal, usually multi media data. The term digital watermarking was used for the first time by [1], actually written in two words: “water mark.” Instead of a confidential or hidden communication, watermarking addresses the security aspects of data and user authentication or data integrity protection, where a digital watermark is a perceptually transparent pattern inserted in digital data using an embedding algorithm and an embedding key. A detection algorithm using the appropriate detection key can retrieve the watermark information.
