India, Oct. 3 -- Google DeepMind has introduced SynthID Bio, a family of techniques that embeds detectable signatures directly into AI-generated protein sequences and predicted three-dimensional structures. Unlike metadata attached to a digital file, the watermark is incorporated into the biological design itself.

The underlying research, published in Nature on September 30, describes the technology as a proof of concept, an important distinction as Google explores its potential use in biosecurity and scientific integrity rather than presenting it as a complete safeguard. That is the problem SynthID Bio is trying to address.

SynthID Bio uses different techniques for protein sequences and predicted structures.

For sequences, it subtly i...
