🍏 iPhone 18 Pro Adds Photo Proof

Reference Image mode works only with the main camera on iPhone 18 Pro and Pro Max. It is unavailable in some countries, and older iPhones lack the required hardware.

The sensor signs each shot with a secret key embedded during production. A protected processor adds another signature, while Apple records which sensor belongs to each phone. Edits fail verification, and sensor firmware cannot change the captured data.

Apple usually adds a signed time mark every 15 minutes. The image is saved as a DNG digital negative, checked in Private Cloud Compute, and returned to Photos as a signed JPEG. It can be viewed on Apple devices running version 27.
