IT Home reported on October 27 that, according to a report yesterday by technology outlet MacRumors, Apple has added SynthID to iOS 27.2. Images generated with Image Playground, as well as some images edited with Apple Intelligence, now carry hidden watermarks.
IT Home learned from the original report that SynthID is a generative AI content identification technology developed by Google that embeds watermarks at the pixel level to mark AI images and videos. Google says the feature does not affect image quality and can withstand post-processing such as cropping, filters and compression.
However, the iPhone itself does not provide a SynthID detection tool. Users must visit the SynthID Detector website to check whether an image carries an AI watermark.
According to the outlet’s tests, images processed using “Expand” and “Reframe” in the Photos app were both identified as AI-generated when checked. Whether the “Clean Up” feature adds a watermark appears to depend on the extent of the edits. Images with minor changes do not receive a watermark, while images with more extensive changes carry a SynthID watermark. All images created with Image Playground carry a SynthID watermark.
