Digital Watermark Mobile Agents

Digital watermarking has emerged as an enabling technology for protecting intellectual property rights of digital information. However, the effectiveness of digital watermarking relies on the efficient detection of watermarks from huge amount of documents in cyberspace. Digital watermark agent provides an efficient solution. A digital watermark agent travels from host to host on a network and acts like a "detective" that detects watermarks and collects evidence of any misuse. Furthermore, we developed an active watermark method which allows the watermarked documents themselves to report their own usage to an authority if detected.
