Apple is rolling out a new authentication feature designed to verify that photos taken on iPhones haven't been manipulated by artificial intelligence. The feature, called 'Reference Image,' will debut with the iPhone 18 Pro lineup.

According to Apple's approach, the new camera sensor in the iPhone 18 Pro will 'sign every pixel it sees,' creating a way to prove a photo's authenticity and that it originated from the device rather than being generated or heavily altered by AI.
