DIGITAL WATERMARKING..

Digital watermarking is the process by which identifying data is woven into media content, giving it a unique, digital identity. Imperceptible to the human senses yet easily recognized by special software detectors, a digital watermark remains constant even through recording, manipulation and editing, compression and decompression, encryption, decryption and broadcast-without affecting the quality of the content. Digital watermarks can identify copyrighted content and associated rights, during and after distribution, to determine copyright ownership and enable rights management policy while enabling innovative new content distribution and usage models. Today, digital watermarks are broadly deployed with tens of billions of watermarked objects and hundreds of millions of watermark detectors in the market, supporting various commercial and government applications. A recent MultiMedia Intelligence study identified digital watermarking as part of a key growth market that could surpass $500 million by 2012.
