Summary

SynthID is Google DeepMind's tool for watermarking and identifying AI-generated content, including images, audio, text, and video. It embeds imperceptible digital watermarks directly into AI-generated outputs, enabling verification of their origin without degrading quality. This technology aims to combat misinformation and improve transparency around synthetic media.

Key Points

  • Embeds imperceptible watermarks into AI-generated images, audio, text, and video to enable provenance tracking
  • Watermarks are designed to be robust against common manipulations like cropping, compression, or reformatting
  • Supports identification of synthetic content without requiring access to the original model or metadata
  • Deployed in Google products including Imagen and Gemini to mark AI-generated outputs at scale
  • Represents a technical approach to AI transparency and reducing harms from synthetic media disinformation

### What is SynthID?

#### Generative AI can help us all to be more creative, productive, and innovative. But it can be hard to tell the difference between content that’s been AI-generated, and content created without AI.

SynthID is our new watermarking tool, designed specifically for AI-generated content. It empowers users to identify AI-generated (or altered) content, helping to foster transparency and trust in generative AI.

### How SynthID works

#### SynthID embeds digital watermarks directly into AI-generated images, audio, text or video. The watermarks are embedded across Google’s generative AI consumer products, and are imperceptible to humans – but can be detected by SynthID's technology.

### AI-generated image and video

SynthID adds an invisible digital watermark to an AI-generated image (or video segment). The watermark doesn’t change the image or video quality. It’s added the moment content is created, and designed to stand up to modifications like cropping, adding filters, changing frame rates, or lossy compression.

### AI-generated audio

SynthID embeds a watermark into any audio generated or published through our AI music generation model Lyria or the podcast generation feature of Notebook LM. It’s inaudible to the human ear, and can’t be altered by common modifications like adding noise, MP3 compression, or changing the speed of the track.
