> Apple Reference Image is not an id system; it's primarily a way to attest that the pixels recorded by the camera sensor have not been altered in any way; the pixels, metadata and timestamp are all cryptographically signed. > There's no way to link a reference image to a person; it's also not possible to determine if a pair of images came from the same device. Some banking apps nowadays ask you to upload a photo of your ID and then use the webcam/selfie camera to confirm that's it's really you (sometimes asking you to move your head in a particular way). But how trustworthy is that process really? Apple Reference Image could be (part of) a solution, by certifying that both images were taken by the same device around the same time.
