IBM is to release new software aimed at stemming the flow of unlicensed music recordings over the internet.
The technology allows mainstream music companies to deter surfers from freely distributing their wares as MP3 files.
The firm is confident that it can enforce copyright despite the emergence of more file-sharing alternatives.
Scott Burnett, from IBM, told Cnet.com that the firm has looked beyond Napster to anticipate the scale of the challenge.
He said: "(You need to ask yourself) what's going to replace it? That's what we are talking about here."
The new Electronic Media Management System will allow labels to control how many times a recording of a song can be distributed.
