&lt;p&gt;If your product treats a photo as evidence that something actually happened, the assumptions underneath it just changed. Apple has published the design for Apple Reference Image, an opt-in camera mode arriving on the iPhone 18 Pro and 18 Pro Max that signs pixel data inside the camera sensor and produces an image you can verify came from a real sensor at a known time. For anyone building newsroom tooling, insurance claims intake, KYC flows, or any pipeline where a manipulated image creates liability, this is the first consumer-scale provenance system that starts its chain of trust at the silicon rather than after the file exists.&lt;/p&gt;</description></item></channel></rss>
