Importing a certificate for C2PA compatibility

By enabling the digital signature function and following the steps below, a digital signature that complies with the C2PA standard can be written when shooting images. Even if you edit the image using an editing application that supports the C2PA standard after shooting, the provenance from shooting to editing will be written to the image, and you can check the authenticity of the image.*

* To guarantee the validity of a C2PA signature, use a certificate for C2PA that conforms to the trust list.

  1. Save the certificate file for C2PA (sigcert.p12 or sigcert.pfx) obtained from Creators' Cloud, etc. to the root directory (the top level of the hierarchy) of the memory card.

    You must name the file “sigcert.p12” or “sigcert.pfx” yourself.

  2. Insert the memory card to which the certificate file for C2PA is saved into the memory card slot of the camera.

    If the camera has two memory card slots, insert the memory card into slot 1.

  3. MENU → [Setup] → [Setup Option] → [Digital Signature] → [Import Certificate for C2PA] → [OK].
  4. Enter the password of the certificate for C2PA and select [OK].

    Enter the password obtained when the certificate was issued.

  5. When a message indicating that importing is complete appears, select [OK].

Hint

  • If you import another certificate for C2PA to a camera that has already imported a certificate for C2PA, it will be overwritten with the newly imported certificate for C2PA.

Note

  • You can write a digital signature compliant with the C2PA standard on still images shot in the [RAW], [JPEG], or [RAW & JPEG] format and on MP4 movies. You cannot write a digital signature on still images shot in the [HEIF] or [RAW & HEIF] format.
