Embed a custom ID into an image invisibly — it survives common compression and re-sharing. Great for copyright protection and AIGC provenance.
If you want to mark your original images without ruining how they look, an invisible watermark is a low-effort option. The ID is embedded into the pixel data — invisible while viewing or sharing, yet still readable after the image is compressed or re-shared.
Because of how the algorithm works, only a limited number of characters fit, so keep it to a short tracking ID and store the full mapping in your own database. If you change the error correction or model, use the same values when extracting.
