Now a days the copyright of multimedia and secrete information is very difficult to transfer across the internet multimedia objects must be compressed before transmitting the data. The JPEG compression is one of the most important criteria in watermarking issue. Watermarking, which belong to the information hiding technique? There is a lot of work begin conducted in different branches in this field, Stegnography is used for secret communication, whereas watermarking is used for content protection, copyright management, content authentication and tamper detection. We classify the techniques based on different domains in which data is embedded. Here we limit the survey to images only. However, making digital data accessible to others through networks also creates opportunities for malicious parties to make sailable copies of copyrighted content without permission of the content owner. Digital watermarking techniques have been proposed as a solution to the problem of copyright protection of multimedia data in network environments.
