o here's a thought.
we now have reliable and safe mRNA for people.
how about we use mRNA to teach our cells how to generate protein keys (key pairs) for crypto. We then have chip based readers that can check to see who we are (and we can build secure protocols for doing this that avoid obvious replay attacks etc), but without committing to using your actual DNA (or other biometrics) which, once compromised, cannot be changed.
chips that decode proteins are around - all the pieces are there.
also, you don't get locked in to one provider (there are lots of people doing mRNA stuff, and we could even open source the mRNA system)....
seems like the way to go -
before anyone tries to patent it:-)
