Google DeepMind introduced SynthID Bio, a watermarking technology for AI-designed proteins that embeds an imperceptible, verifiable watermark into biological designs such as protein sequences and predicted 3D structures. In laboratory tests, watermarked designs matched the performance and natural diversity of unwatermarked versions, aiming to strengthen biosecurity and preserve the integrity of open scientific databases.

## Evidence

Verbatim from https://blog.google/innovation-and-ai/models-and-research/google-deepmind/synthid-bio/:

> SynthID Bio embeds an imperceptible, verifiable watermark directly into biological designs, such as AI-generated protein sequences and predicted 3D structures. In laboratory tests across target proteins, our watermarked designs successfully matched the performance and natural diversity of unwatermarked versions.
