your DNA? They could probably even send it to this DNA ink company, and they'd make your enemy ink out of your own DNA without even noticing. Doesn't seem very secure to me.
[Yeah, it's not crypto related, but I've been wondering about this since the topic was first brought up, and am somewhat surprised that of the few messages there were making fun of the DNA ink, none mentioned this fact. Is that because it's too obvious to mention, or is there something I'm not thinking about which makes DNA ink useful after all?]
A much more interesting spin on this would be a variety of ways to encode throughout a substance in an inert but permanent way a public key. Whether it's an easily identifiable molecule or some type of deep etching, you could do things like mark all the parts of a car or all the paint, fabric, plastic, etc. of a work of art. DNA isn't very good really since it's mostly the same and based a lot on probabilities. sdw -- Stephen D.
