چکیده مقاله :
Due to high speed computer networks, the use of digitally formatted data has increased many folds.The digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. Digital Watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .Digital watermarking is a well-known technique used for copy rights protection ofmultimedia data. A number of watermarking techniques have been proposed in literature. DigitalWatermarking is the process that embeds data called a watermark into a multimedia object such thatwatermark can be detected or extracted later to make an assertion about the object. A variety oftechniques in different domains have been suggested by different authors to achieve above mentionedconflicting requirements. All the watermarking techniques are different from each other and are usedfor differing applications.
