Your iPhone Can Now Prove a Photo Is Real. Here Is the Catch
The iPhone 18 Pro can sign every pixel its main camera captures and keep an unalterable reference copy beside the photo.

It is opt-in, cannot be captured in the EU at launch, and sits outside the open standard Google, Samsung and Leica chose.
