3.4. Digital signature function (Android only)
Depending on your camera model and the country or region where you reside, you may be able to use the digital signature function. You can also retain the digital signature when editing images to which the camera assigned a digital signature when they were shot.
- The only items that can be edited are those accessible using [Edit] (editing metadata, cropping, rotation, and inclination correction).
- The digital signature function will initially be made available to customers affiliated with certain news organizations. We will make an announcement when it becomes available to other customers.

C2PA-compliant digital signatures
After enabling the camera’s digital signature function and reading the C2PA certificate into the camera, the camera becomes capable of writing C2PA-compliant digital signatures to images. As a result, when such images are edited using Transfer & Tagging, the edit history is written to the image, allowing the image’s authenticity to be verified.
