About this site
This site is a site to prove your photography is not AI. We use C2PA technology to prove your photo.
Please upload a photo taken with a C2PA-compatible camera to this site. Read the C2PA information and display the verification result. The verification result can be shared on SNS, etc.
Photos edited with non-C2PA-compatible software cannot be verified accurately. If there is no C2PA-compatible editing software, please upload the photo without editing.
About C2PA
C2PA is a standard for verifying the authenticity of content. It checks for signs of tampering from multiple angles — like metadata, signatures, and edit history. If anything seems off, this site will mark the image as untrustworthy.
Trustworthiness of signers
Currently, the signer's whitelist is a provisional list. Signatures from businesses not registered in this list are treated as untrustworthy. The provisional list is available at the following address.
