Apple is working on “Apple Reference Image,” a photo provenance system that will verify whether an image was captured with an iPhone. References to the feature were found in a privacy disclosure included in iOS 27 beta 5, but it is not yet available. According to the text, there will be a “Reference” mode option in the Camera app that users will be able to select. Using this mode will incorporate provenance data into the image metadata. Images captured with an optional reference mode can be authenticated to confirm that they were taken with an iPhone. Authentication is performed by tapping the Reference badge on the image, which sends the raw image, sensor signatures, capture time frame, and unique sensor hardware identifiers to Apple’s Private Cloud Compute (PCC) servers. PCC uses the information to determine if the camera captured the photo, assigns it a unique ID, and then returns an authenticated version to the user’s device. When authenticating a photo, Apple receives sensor data, a hash, and the evaluation results, but not the raw photo. Apple may refuse to authenticate images from a sensor that may be compromised and may retroactively revoke previous authentications for a sensor. Authenticated photos can be viewed on an iPhone, iPad, or Mac, and the Reference badge can also be clicked on a Mac. Images must be captured in Apple’s specific Reference mode to be authenticated, suggesting it’s a feature aimed at professional photographers, journalists, and others who need to verify images. There may also be a video component, as Apple’s disclosure mentions “photos or videos” and “uncropped footage.” Reference mode provides hardware-backed evidence that an image was captured with a physical camera sensor, which is useful at a time when AI can generate realistic-looking images. AI images are often watermarked or tagged using metadata to ensure they can be identified as fake, including images from Image Playground. Camera manufacturers like Leica, Sony, and Nikon use C2PA content credentials for authentication, and Google has also adopted them for the Pixel 10 line. It appears that Apple’s authentication system serves a similar purpose.
