Google, OpenAI announce big expansion of SynthID digital watermarks

Google is expanding SynthID and C2PA verification across Search, Chrome, and the Gemini app.

OpenAI, Kakao, and ElevenLabs will also adopt SynthID in their products, widening support for AI watermarking.

The goal is to make AI-generated content easier to identify and improve provenance checks for images, audio, and video.

The move could help users spot deepfakes and other synthetic media as they become harder to distinguish from real content.
