Apple is seemingly developing an iOS feature that can verify when a photograph was taken using an iPhone camera. 9to5Mac reports that the iOS 27 beta 5 includes code references for an “Apple Reference Image” system that can embed provenance metadata into iPhone photographs at the point of capture — enabling users to prove where the photo originated, and that it isn’t AI fakery.
Apple Reference Image isn’t currently live, but a privacy disclosure in the iOS beta notes that the feature will be off by default. When (or if) it does roll out, 9to5Mac says it can be enabled via Settings > Camera > Reference Image > Reference Mode, and that only photographs taken using a new “Reference” option in the iPhone Camera app will include the provenance information required for authentication.
MacRumors has more details about the actual authentication process, which doesn’t occur automatically and instead requires users to tap a Reference badge on the photograph. This reportedly sends the raw image and its embedded provenance data — including sensor signatures, capture time frame, and unique hardware identifiers — to Apple’s Private Cloud Compute servers for verification, and then returns the authenticated version with a uniquely assigned ID.
Apple doesn’t access the raw photo itself during this process, but it may receive sensor data that allows it to prevent images connected to compromised sensors from being authenticated, or retroactively revoke prior authentication on images associated with the sensor.
