Google says SynthID has been used to watermark over 10 billion pieces of content

Two years ago, Google created SynthID, which embeds invisible watermarks into AI-generated media. At Google I/O, the company said over 10 billion pieces of content have now been watermarked with the technology. Google is also expanding its partnerships to ensure that more content is watermarked with SynthID and more organizations can detect the mark. 

At the event, Google said it’s making it easier to detect the watermark. The company’s new SynthID detector can now identify if an image, audio track, text, or video has SynthID in it — whether it’s in the whole piece or even just a part. This will begin to roll out to early testers today. Want to read more? Check out the full story on SynthID here.
