Can "fingerprinting" bring a truce to the Web's video-copyright wars?..
Video-sharing sites such as YouTube say they are protected from liability for copyright claims under "safe harbor" provisions in the Digital Millennium Copyright Act of 1998. But, under the DMCA, sites that have "actual knowledge" or control of infringing content can lose such protections. "What these filters do is potentially create more knowledge, more awareness of what's going on," says Fred von Lohmann, senior intellectual-property attorney at the Electronic Frontier Foundation in San Francisco. "There is some residual risk that you could lose the safe-harbor protections if you have too much of that kind of knowledge."
