What is SynthID?

SynthID is a cutting-edge technology developed by Google DeepMind that embeds imperceptible watermarks into AI-generated content. These watermarks remain detectable even after modifications like cropping, filtering, or compression.

By providing a robust method to identify synthetic content, SynthID helps combat misinformation and ensures responsible AI deployment across industries.

How SynthID Works

1. Generation

During content creation, SynthID modifies the generation process to embed cryptographic signatures without affecting output quality.

2. Watermarking

The watermark is distributed throughout the content, making it robust against modifications while remaining imperceptible to users.

3. Detection

Specialized algorithms can detect the watermark presence and verify AI-generated content authenticity with high confidence.

Technical Implementation

Text Watermarking Approach

  • Modulates sampling probabilities during generation
