We're looking forward to seeing the new artificial intelligence side of Siri when iOS 27 launches, but it appears that Apple may have additional tools in the works. In its analysis of the latest operating system beta, 9to5Mac noticed some signals that Apple might be working on a photo authentication feature. Apple Reference Image appears to be a tool that will verify that a photo was taken with an iPhone camera. This approach of Reference Image to create confirmation of content's provenance could be a useful counterpart to those metadata watermarking efforts. Since all this is happening in an ongoing beta test, however, it's possible that Reference Image won't be included when iOS 27 does have its public rollout this fall.
