Using Plant DNA for Authentication
Turns out you can create unique signatures from plant DNA. The idea is to spray this stuff on military components in order to verify authentic items and detect counterfeits, similar to SmartWater. It’s a good idea in theory, but my guess is that the security is not going to center around counterfeiting the plant DNA, but rather in subverting the systems that apply, detect, and verify the chemicals.

I’m confused by this. Is the claim that people will swap out real for counterfeits at some point in the production process? I mean, what’s their threat model like? I would imagine the counterfeiter sells you the counterfeited part before you have had time to apply the plant DNA spray.
