Google DeepMind introduces SynthID Bio to watermark AI-designed proteins

Google DeepMind has introduced SynthID Bio, a technology that embeds an imperceptible, verifiable watermark into AI-designed protein sequences and predicted 3D structures. In laboratory tests across target proteins, watermarked designs matched the performance and natural diversity of unwatermarked versions. The company says the watermark provides a provenance layer intended to strengthen biosecurity and preserve the integrity of open scientific databases.
