What if I just reframe my picture instead of cropping? Every photo is a choice. A choice of what to show and what not to show.
(1) a trusted application
(2) using a builtin device camera
(3) of a device running attested trusted operating system
(4) and any subsequent edits reference such photo’s original hash.
Hopefully stronger assertions could come in the future. This is just to combat digital forgeries and synthetically generated images. It also does nothing against real-world forgeries like actors wearing costumes or makeup.
