Apple’s Reference Image mode on the iPhone 18 Pro signs each capture with a camera-sensor private key, creating a tamper-evident RAW record (digital negative) that Apple’s Private Cloud Compute verifies with signed timestamps before delivering a final, signed JPEG—offering offline verification and strong privacy safeguards, with the feature opt-in and limited to newer hardware.
Sony has expanded its video authenticity verification technology to support more cameras and now includes verification of video content, enhancing the credibility of news media by ensuring content authenticity and combating AI-generated manipulation, with support for C2PA standards and proprietary metadata features.
Major camera manufacturers like Nikon, Sony, and Canon are combating the proliferation of AI-generated images by introducing 'Verify' watermark technology that embeds digital signatures into photos. This allows for the authentication of images by detailing when and where they were taken, and by whom. The Verify web tool has been developed in collaboration with news organizations and tech companies to check image authenticity for free. The move comes as AI images become more common, raising concerns about distinguishing between real and synthetic media. Sony and the Associated Press have already tested this technology, and Intel and Google are also working on methods to identify AI-generated images.
