Apple iOS 27.2 system adds SynthID hidden watermark to AI-generated images.

Apple iOS 27.2 system introduces SynthID feature, adding hidden watermarks to images generated in the Photo Playground and some intelligently edited images. SynthID is an AI content recognition technology developed by Google, which embeds watermark markers at the pixel level for AI-generated images, without affecting image quality and capable of resisting post-processing. Users need to visit the SynthID Detector website, where images processed with 'Extensions' and 'Recompose' in the 'Photos' app are shown as AI-generated.
