Apple is working on a new iPhone feature that could make it easier to verify whether a photo was actually captured with an iPhone camera. According to 9to5Mac, references found in iOS 27 beta 5 point to a feature called Apple Reference Image, which uses camera hardware and photo metadata to authenticate the source of an image.
The feature appears to be designed for a world where AI-generated and heavily manipulated images are becoming increasingly difficult to distinguish from real photos. Instead of trying to identify an image as AI-generated after the fact, Apple’s approach would establish provenance when a photo is captured.
Apple Reference Image Could Authenticate iPhone Photos
Apple Reference Image appears to work through a new Reference mode in the Camera app. When enabled, photos captured in this mode can later be authenticated using information tied to the iPhone camera and the original image.
The feature is expected to be optional and off by default. References found by 9to5Mac indicate that users will be able to enable it through Settings > Camera > Reference Image and then activate Reference mode in the Camera app.
This distinction is important because photos taken normally would not contain the provenance information required for Apple’s authentication system. Simply taking a photo with an iPhone would not automatically make it verifiable.
When a user chooses to authenticate a Reference Image, the photo and its associated provenance data are sent to Apple’s Private Cloud Compute system for verification. Apple is designing the system so that it does not have access to the raw photo itself. Once verified, the image receives a unique identifier that can be used to confirm its authenticated status.
Apple could also revoke previous authentications if it determines that the camera sensor associated with them has been compromised.
Authenticated Photos Could Keep Their Provenance When Shared
Apple is also working on ways to preserve this authentication information when users share photos. Other Apple devices could check an authenticated image locally to determine whether its provenance remains valid without telling Apple which photos are being viewed.
The information carried with an image can vary depending on how it is shared and whether the photo is an original, edited, or authenticated version. Apple is also adding a Transfer with Provenance option for USB transfers, allowing authenticated photos moved to a Mac or PC to retain their Reference Image data.
There are some important privacy considerations. Apple says certain sharing options can include hardware identifiers and other associated data, including uncropped footage in some cases.
Apple Reference Image could give photographers, journalists, businesses, and ordinary users a new way to establish that an image originated from a real iPhone camera. However, the feature is still in development, and Apple has not announced when it will become available or whether all of the functionality found in iOS 27 beta 5 will make it into the final release.
