References included in iOS 27 beta 5 point to a new feature designed to authenticate the camera source of an iPhone photo. Here are the details. Apple working on new reference image feature While the challenge posed by synthetic images attempting to pass as authentic is not new, it has become an increasingly pressing issue with the rise of AI generative images. What used to take a skilled photo editor hours, or even days, can now be accomplished in seconds, with little more than a brief message based on a half-formed idea. To address this, several companies have already introduced ways to make AI-generated content easier to identify. Google, for example, developed SynthID, which embeds imperceptible watermarks on images and other AI-generated media. The technology has since expanded beyond Google’s own products, and companies like OpenAI have adopted it for generated images. Similarly, Meta has introduced labels for AI-generated content on Facebook, Instagram, and Threads, although those systems have faced limitations in reliably identifying manipulated media, even when created by the company’s own AI models. Now, it looks like Apple might also be preparing to address the issue, in addition to “flagging” the metadata of images created through Image Playground. New code in iOS 27 beta 5 shows that the company is working on something called Apple Reference Image, which is designed to authenticate the source of photos using unique data tied to the iPhone camera hardware that captured them. In line with Apple’s privacy-focused approach to cloud-based processing of potentially sensitive user data, the company is designing Apple’s reference image in a way that prevents Apple from accessing the raw photo. Instead, the system sends the image to Private Cloud Compute for authentication, while only certain sensor information and photo metadata are sent to Apple. Interestingly, if Apple determines that a sensor may have been compromised, it can revoke previous authentications associated with that sensor. As it stands, the feature is disabled by default and once enabled, it will be activated via Settings > Camera > Reference Image and tapping Reference Mode. Privacy splash screen displayed when activating the Apple reference image. Importantly, reference mode must be used when capturing the photo via a new “Reference” mode in Camera. This means that photos taken will typically not contain the provenance information needed to be authenticated later. Reference mode itself doesn’t seem to authenticate the photo automatically. Instead, users can choose to authenticate it later, at which point the raw image and associated provenance data is sent to Private Cloud Compute for verification. During authentication, Apple assigns the photo a unique ID. Another privacy-focused aspect of the system is that authenticated photos can also be shared with other people, whose Apple devices can locally check whether the photo remains authenticated, without telling Apple which images they are viewing. The information included when sharing may vary depending on the method used (AirDrop, Messages, etc.) and whether the photo is an original, edited or authenticated version. Notably, if the user chooses to share “All Photo Data,” Apple says the transfer may also include unique hardware identifiers and any uncropped material associated with the image. Apple is also adding a “Transfer with Source” option for USB transfers. When enabled, authenticated photos transferred to a Mac or PC will include their reference image data, while unauthenticated photos may still contain provenance information, such as unique hardware identifiers and any uncropped footage.
