Google DeepMind introduced SynthID Bio, a family of watermarking methods for AI-generated proteins. The approach embeds a detectable signature into amino acid sequences or 3D structures without compromising biological function in laboratory tests. SynthID Bio is intended to strengthen biosecurity by enabling verification of synthetic biological designs and preserving the integrity of public databases.

## Evidence

Verbatim from https://deepmind.google/blog/introducing-synthid-bio/:

> SynthID Bio embeds an imperceptible signature directly into the biological code, ensuring the watermark is verifiable not just on a digital model but on the synthesized, physical protein itself – all while preserving its biological function in laboratory testing.
