Apple develops photo-authentication feature for iOS 27 to verify iPhone-captured images

Apple is working on a new photo-authentication feature for iOS 27 that aims to verify whether an image was captured on an iPhone, signalling a shift towards more robust image provenance tools amid industry efforts to combat AI-generated deepfakes.

Apple is preparing a photo-authentication feature for iOS 27 that could help confirm whether an image was captured on an iPhone. The function, reportedly called Apple Reference Image, is being developed as part of the company’s broader work on image provenance, a term used for methods that track where a picture came from and how it was made.

According to 9to5Mac’s analysis of the latest iOS 27 beta, the feature would rely on selected sensor data and image metadata being checked through Private Cloud Compute. In practical terms, that would allow the system to compare device-level information with the photo itself and decide whether it appears to have originated from an iPhone camera. The option would apparently require a new Reference mode to be enabled in the Camera app before authentication could be used.

The timing reflects a wider industry push to distinguish authentic photographs from AI-generated or heavily altered images. Much of the current effort has centred on watermarking, including tools Apple already uses in Image Playground and other image-editing features under development. Google is also expanding its SynthID watermarking system. Apple’s approach would be different, focusing less on marking generated content and more on verifying capture data from the device itself.

That said, the feature remains in beta and may not ship with the public release of iOS 27. Apple is also building out other Photos app changes in the same release, including new AI editing tools, improved organisation features and categories such as Captured by Me and Identity Documents, suggesting a broader overhaul of how the iPhone handles, sorts and understands images.
