Google’s SynthID Bio can watermark AI-designed protein binders without breaking them

Google DeepMind built SynthID Bio, a watermark that hides a signature in the amino acid sequence of an AI-designed protein and in the atomic coordinates of its predicted 3D structure, and wet-lab tests on protein binders showed the watermark leaves their function intact. DeepMind says the signature can be verified on the physical protein after synthesis, and it aims the watermark at DNA synthesis screening.

Google DeepMind has built SynthID Bio, a watermark for AI-designed proteins, and shown in wet-lab tests on protein binders that it leaves their function intact. The method hides a signature in the amino acid sequence of a designed protein and in the atomic coordinates of a predicted 3D structure. DeepMind says the signature can be checked on the physical protein after synthesis. DeepMind aims the watermark at DNA synthesis screening.
