Microsoft’s implementation of AI watermarking in its Paint and Photos applications has come under scrutiny due to its potential link to user identification. This development raises significant questions about privacy in the context of AI-generated content.
Watermarking and Compliance with EU Regulations
As part of its compliance with the EU’s Code of Practice on Transparency of AI-generated Content, Microsoft has adopted a watermarking approach that goes beyond the minimum requirements. The regulation mandates that AI-generated content be marked in a machine-readable format, but it does not specify the exact methods for achieving compliance. This allows companies like Microsoft to choose technologies that align with the goals of transparency and reliability.
Technical Details of Microsoft’s Approach
A recent analysis by Xusheng Li, a software developer at Vector 35, revealed that Microsoft embeds a globally unique identifier (GUID) into AI-generated images. This GUID is linked to the prompt used to create the image and is sent to Microsoft for moderation before being encoded into the image’s pixels. This means that if Microsoft associates each prompt with a specific user, it could theoretically identify users based on the watermark in their images.
Privacy Implications and User Concerns
The practice of linking user prompts to a GUID has raised alarms among privacy advocates, reminiscent of past concerns regarding tracking mechanisms used by laser printers. Li pointed out that while Microsoft has disclosed its AI safety measures, it has not sufficiently clarified the implications of embedding a GUID that could be traced back to users.
Industry Context and Alternatives
Microsoft is not alone in exploring watermarking technologies. Other companies, such as Meta and OpenAI, are also developing their own solutions for marking AI-generated content. For users who wish to avoid having their images tracked, alternatives like open-source models such as Stable Diffusion are available, allowing for on-device processing without embedded tracking identifiers.
