Study of Contemporary Digital Watermarking Techniques
Digital watermarking is a concept of embedding authentication information. It uses an algorithm for inserting a watermark to protect the copyright of media. It became very important in various application areas like video, audio, text, image etc... A number of watermark techniques have been proposed by many authors in the last several years. However, there is a need to have enough analysis and comparative study on these techniques. This paper has discussed the conventional watermark techniques from various points of view. Currently watermark techniques based on the transform domain are more popular than those of the spatial domain.
