Securely encoding authenticity tokens into artificial intelligence (AI) generated content

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 each of the DCT blocks using singular value decomposition (SVD);
• encoding single bits of an encrypted image identifier for the generative image into each first singular value of each set of singular values associated with each of the DCT blocks, wherein an image identifier of the encrypted 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 each first set of singular values with an encoded first singular value.

A system, comprising:

• a processing system;
• and
• a computer memory comprising instructions that, when executed by the processing system, cause the system to perform operations of:
• 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.
