Apple explores iOS provenance feature to authenticate iPhone photos at capture

Apple appears to be developing a feature in iOS 27 beta 5 that would allow users to authenticate photographs taken with an iPhone camera at the point of capture. According to reporting by 9to5Mac, the system—referred to as 'Apple Reference Image'—would embed provenance metadata into photos, enabling users to prove where the image originated and that it is not AI-generated content.

The feature is not currently active, but a privacy disclosure in the iOS beta notes that it will be off by default. If enabled by the user via Settings > Camera > Reference Image > Reference Mode, only photographs taken using a new 'Reference' option in the iPhone Camera app would include the provenance information required for authentication.

Authentication would not occur automatically. Users would need to tap a Reference badge on a photo, which would send 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. Upon successful verification, the photo would receive a uniquely assigned ID and could be viewed on an iPhone, iPad, or Mac.

Apple states it does not access the raw photo itself during this process, but may receive sensor data that could be used to prevent images linked to compromised sensors from being authenticated or to retroactively revoke authentication for images associated with such sensors.

The system resembles the C2PA Content Credentials provenance standard, which is supported by several camera manufacturers including Canon, Nikon, Sony, FujiFilm, and Leica, as well as Google’s Pixel 10. Apple has not adopted C2PA to date.
