Suno Introduces Digital Watermarking for Music | Responding to AI Fraud and EU Regulations

What you'll learn from this article:

• Why AI music platform "Suno" is introducing digital watermarks
• The reality of copyright issues and streaming fraud surrounding AI music
• How this relates to tightening EU AI Act regulations
• The impact on the music industry and creators

What Is Suno? At the Forefront of AI Music Generation

Suno is an AI service that automatically generates full-fledged songs simply by entering text. While it allows anyone to easily create professional-quality music, that very accessibility has led to a rise in misuse.

On August 6, 2026, Suno CEO Mikey Shulman announced that all future generated tracks would incorporate "audio watermarks" and "fingerprint technology." In other words, songs created with Suno will have an invisible mark embedded in them indicating, "This song was made by AI."

Why Watermarks Now?

There are two major reasons behind this decision: copyright litigation and streaming fraud.

A Storm of Copyright Lawsuits

In June 2024, the Recording Industry Association of America (RIAA) sued Suno, claiming that "Suno used copyrighted music for AI training without permission." Initially, 560 songs were at issue, but by May 2026, Sony and Universal had expanded the scope to 61,026 songs. Damages are said to potentially reach up to $9 billion (approximately 1.3 trillion yen).

Suno has been contesting the case by asserting "fair use," but in July 2026, a German court also handed down a ruling of copyright infringement. Legal pressure is mounting around the world.

The Worsening Problem of AI Music Streaming Fraud

The other major issue is "streaming fraud." This involves uploading large quantities of AI-generated songs to Spotify or Apple Music and using bots (automated programs) to play them repeatedly in order to illegally earn revenue.

For example, in September 2026, musician Michael Smith was indicted in the United States on suspicion of creating thousands of AI-generated songs, using bots to stream them, and fraudulently obtaining approximately 1.4 billion yen. According to music distribution service Deezer, data suggests that up to 85% of AI-generated music is intended for fraudulent purposes.

To prevent its own platform from being exploited in such schemes, Suno moved to implement download restrictions and watermarking.

How Watermark Technology Works

Suno is introducing two types of technology:

• Audio watermarks: Technology that embeds an electronic mark inaudible to humans into audio files. These marks are designed to be difficult to remove even when music is copied or compressed.
• Fingerprint technology: A system that records the "acoustic fingerprint" of a track, enabling identification of "this song was made with Suno" when it is uploaded to other platforms.

The specific technology to be used has not been disclosed, but existing technologies such as Google's SynthID have been mentioned as candidates. Suno has announced that it aims for "marking that does not compromise audio quality and is difficult to remove."

In addition, the copyright detection systems "Musixmatch" and "Sentinel" will also be introduced to strengthen measures against imitation of existing works.

Alignment with the EU AI Act

The timing is noteworthy. Suno's announcement came on August 6, 2026, but just four days earlier, on August 2, Article 50 of the EU (European Union) AI Act came into force.

This law requires that AI-generated images, videos, and audio must display "in a machine-readable format that they are AI-generated." Violations could result in massive fines for companies.

In other words, Suno's introduction of watermarks is not merely a voluntary measure — it is also a legal response required to continue operating in the EU market. However, it has been pointed out that "no perfect technology that meets all requirements yet exists."

Impact on the Music Industry

This development will have a significant impact on the music industry as a whole.

Protecting Creators' Rights

With AI-generated music clearly identifiable, it becomes easier to distinguish such tracks from songs created by real artists. Streaming services will be able to create dedicated categories for AI music and adjust revenue distribution accordingly.

Effectiveness of Anti-Fraud Measures

With watermarks in place, Spotify and Apple Music can immediately recognize "this song was made with Suno." Automatic detection and blocking of mass uploads also becomes possible. According to music distribution service Deezer, more than 20,000 AI-generated songs are uploaded per day, accounting for 18% of the total. Watermarking is a first step toward stemming this flood of fraudulent content.

Remaining Challenges

On the other hand, technical challenges remain. While watermarks are described as "difficult to remove," the possibility that technically skilled individuals could erase them using specialized tools is not zero. Furthermore, if other AI music services (such as Udio) do not adopt watermarking, fraudsters will simply migrate to those platforms.

A unified industry-wide standard and a framework for cooperation are needed.

Summary

• Suno announced in August 2026 that it would introduce watermarks to all generated tracks
• The background includes copyright litigation worth up to $9 billion and the worsening of streaming fraud
• The announcement coincided with the enforcement of the EU AI Act, with legal compliance also being one of the objectives
• The music industry has high expectations in terms of both fraud prevention and creator protection
• Technical challenges and industry-wide cooperation will be key going forward

While AI music brings democratization of creativity, it has also given rise to new problems of copyright infringement and misuse. Suno's decision can be seen as an important step toward the healthy growth of the music industry in the age of AI.
