Researchers at Royal Philips Electronics are developing new "fingerprinting" technology that could automatically identify and block transmission of digital-video files, potentially handing movie studios a new weapon in its war on peer-to-peer networks.

The technique would be similar to technology already being used to track and prevent copying of music files on some university networks. Philips' audio fingerprinting technology is central to Napster founder Shawn Fanning's new company Snocap, which aims to turn file-swapping networks into digital-song stores.

Once completed, Philips' technology--along with related tools from other companies--could be a powerful weapon in Hollywood's increasingly aggressive attempts to choke off the flood of films being traded online. For now, the tools are in an early stage of development, but Philips has begun to show them to potential partners and customers.
