Sony Develops AI Music Attribution Tech to Track Copyrighted Material

Sony Group has developed technology capable of identifying original music embedded within tracks generated by artificial intelligence (AI). This development aims to address growing concerns about copyright infringement in the age of AI-generated content and potentially establish a framework for compensating songwriters and rights holders when their work is used in AI training or output.

Tracking AI’s Musical DNA

The technology, first reported by Nikkei Asia on February 16, 2026, operates through two primary methods. When AI developers collaborate with Sony, the system directly analyzes the base models used to generate music, extracting training data. In cases where cooperation isn’t possible, the technology compares AI-generated music against existing music catalogs to estimate the influence of original works.

According to Musically, the system can even quantify the contribution of specific artists, for example, identifying that a track incorporates “30% of the music used by the Beatles and 10% by Queen.”

Addressing Copyright Concerns and Litigation

This move comes amid increasing legal pressure on AI music generators. Sony Music Entertainment has joined lawsuits against AI music platforms like Suno and Udio, alleging “mass infringement” of copyrighted material. While Universal Music Group and Warner Music Group have reached settlements and licensing agreements with Udio, Sony has taken a different approach, focusing on technological solutions.

As reported by Music Business Worldwide, Sony envisions a future where this technology is integrated into AI development processes and used in licensing negotiations, potentially forming the basis of a revenue-sharing system.

Beyond Music: Expanding AI Attribution

The development of this AI attribution technology isn’t limited to music. Sony AI, the research and development division of Sony Group, has also created methods to prevent AI systems from replicating artistic styles, including those of Studio Ghibli, demonstrating a broader commitment to protecting intellectual property in the age of AI.

Japanese Copyright Law and Revenue Sharing

Under Japanese copyright law, music rights are divided into copyrights held by songwriters, composers, and publishers, and neighboring rights held by performers and record producers. Sony’s technology aims to address both aspects, ensuring fair compensation for all rights holders when their work contributes to AI-generated music.

Key Takeaways

• Sony Group has developed technology to identify copyrighted music used in AI-generated tracks.
• The technology operates through direct analysis of AI models (with cooperation) or comparison against existing catalogs.
• This development aims to address copyright concerns and establish a framework for revenue sharing.
• Sony AI is also working on preventing AI from replicating artistic styles.
