NAPSTER are to employ “digital fingerprinting” in its continuing efforts to remove copyrighted material from its service.

Napster have teamed up with the company Relatable, whose filtering process involves identifying songs by their acoustic properties, rather than the filename of the song.

Speaking about the deal, Napster CEO Hank Barry said: “Digital fingerprinting technologies are developing rapidly, and Relatable’s new acoustic fingerprinting technology shows great promise. We are now working closely with Relatable’s engineers to co-ordinate their technology with our file filtering systems; we hope they will be a substantial part of our overall filtering solution.”

Napster have come under fire in recent weeks over their alleged inability to filter copyrighted MP3 files from their system, following a court injunction earlier in the year ordering them to do so.
