THE AI ANGLE
Designing proteins while embedding cryptographic watermarks

Google DeepMind developed SynthIDBio to watermark AI-designed proteins without altering their biological function. DNA synthesis providers can use cryptographic keys to confirm sequences came from trusted researchers. Unmarked designs can then receive closer scrutiny during threat screening.
