Google's SynthID AI watermarking tech is being adopted by OpenAI, Nvidia, and more
Summary
Google developed SynthID, a technology that adds hidden digital watermarks to AI-generated images, videos, and audio to identify them. Now, Google is working with other companies like OpenAI and Nvidia to use SynthID, making it easier to recognize AI-created content across different platforms.Key Facts
- SynthID was first shown by Google three years ago and has labeled 100 billion images and videos and 60,000 years of audio so far.
- SynthID embeds a digital watermark directly into the pixels of images and videos or the waveform of audio, making it hard to remove even after editing.
- Google uses another system called C2PA, which adds metadata describing how content was made, and it is used in Pixel 10 phones and soon in Pixel 8 and 9 phones for videos.
- Google’s Gemini chatbot and apps can scan content to detect SynthID watermarks and confirm if the content is AI-generated.
- Several companies, including Nvidia, OpenAI, Kakao, and ElevenLabs, will start adding SynthID watermarks to their AI content.
- Many AI models still produce content without watermarks, especially public and open-source ones, so not all AI content will be identifiable.
- Google plans to integrate SynthID detection into tools like Search, Chrome, Lens, and AI Mode to make checking easier.
- There is no public SynthID API yet, but Google will soon offer an API for trusted partners to help flag AI content and improve detection.
