Digital watermarking has been an effective technique for copy protection, copyright protection, medical application, data authentication, fingerprinting and other applications over recent years. In this technique, certain information called watermark is embedded inside the original data. The main data can be an image, video, audio and text. Requirements of a watermarking system will be different depending on the type of the host media and for what purpose it is used. In this article, a study on digital image watermarking is presented. In the study, general concepts of watermarking, different types of digital image watermarking, and the watermark embedding and extraction techniques are discussed in brief.
