Sony has developed a technology which can tell if AI-generated music uses, or was trained on, music previously generated by others, reports the Nikkei.
It can also measure the amount of the contribution made by previously composed music used in a piece of music which it analyses.
This allows the technology to decide on the share of royalties to which the composer of the original music is entitled.
AI developers have been accused of using copyrighted music without permission to train machines. AI-generated songs using the voices of well-known singers have been played online.
The Japanese company thinks the technology will help create a system that distributes revenue generated by AI music to original songwriters based on their contribution.
