Apple is adding Apple Reference Image to the iPhone 18 Pro, creating a cryptographic signature at capture that can help viewers verify whether a photo is authentic and unaltered. The original version remains available as a comparison copy if the image is edited. The system sends selected image details to Apple Private Cloud Compute (Apple's secure AI-processing cloud) and allows signed photos and reference signatures to be shared. It will not launch in the European Union or China. Apple-generated images from Image Playgrounds and Apple Intelligence editing tools, including Extend and Spatial Reframe, will instead carry SynthID markers, an imperceptible watermarking system developed by Google's DeepMind. The feature arrives with a major camera overhaul, including a 48-megapixel main camera, variable aperture from f/1.8 to f/1.48, and a new Pro mode with manual controls. The phone also introduces the A20 Pro chip, which Apple says delivers faster CPU, GPU and AI performance, alongside improved cooling. The iPhone 18 Pro starts at $1,199 with 256 GB of storage, while the iPhone 18 Pro Max starts at $1,299. Pre-orders open Saturday and shipping begins September 18. Apple said recent price increases reflect global chip shortages tied to rising AI-computing demand, while its iPhone division reported $54.25 billion in quarterly revenue, up 22 percent and ahead of analyst expectations. The authentication system is intended to address the spread of convincing synthetic images, although its reach may be constrained by the need to share reference signatures and its absence from two major smartphone markets.
