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.
