Microsoft patents method to hide ID tags in AI images
Microsoft has been granted a patent for a system that embeds hidden digital identifiers into images created by artificial intelligence. The method uses complex math to tuck these tags into the image's data in a way that keeps the picture looking high-quality while making it traceable.
In the filing’s own words
This disclosure describes utilizing an image encoding system that provides a comprehensive and robust defense strategy for artificial intelligence (AI) generated content (AIGC). Specifically, the image encoding system provides a framework that combines multiple security measures with various transform domain methods in order to encode an image with multiple instances of an encoded image identifier. The image encoding system achieves a balance between maintaining the high quality of generative images and ensuring the traceability of the images. By doing so, the image encoding system addresses numerous technical challenges presented by AI-generated media, thereby ensuring that generative images are protected against unauthorized usage.
What exactly they claim (claim 1)
1. A computer-implemented method for encoding authenticity tokens into artificial intelligence (AI) generated content, comprising: generating discrete cosine transform (DCT) blocks for a generative image based on using discrete wavelet transform (DWT) and DCT; generating a set of singular values for a first DCT block using singular value decomposition (SVD); encoding a bit of an image identifier for the generative image into a first singular value of the set of singular values, wherein the image identifier indicates origin information about the generative image; and generating an encoded generative image based on applying an inverse SVD, an inverse DCT, and an inverse DWT to the set of singular values having an encoded singular value.
