Somebody named Banksy using a bank of bank notes for authentication?
Sounds like a old joke with newfound currency to me.

#32Earlier quoted context omitted.
That’s a rather restrictive definition of cryptography, don’t you think?
Well yes strictly speaking it's not just math, but usually it does imply math. What are some examples of cryptography without math of some kind?
Character substitution comes to mind, as described in https://en.m.wikipedia.org/wiki/The_Adventure_of_the_Dancing...

#33There’s nothing cryptographic about this. It’s a central authority that either says “yes it’s real” or not. The system revolves around trust in that central authority. Everyone can easily fake a certificate which cannot be independently falsified without asking that central authority, who will be more likely to check their books than to do anything related to the actual certificate.
While not actually cryptographic in nature, it's a nontrivial authentication protocol that is better than a more traditional certificate, as discussed in the article, and potentially very impressive end enlightening for the not too technically minded people who follow art and art trade.

Browser uses cryptography, so one does not have to contact CA for every visit.
Banksy does not, so you do have to contact “CA” every time.

#35This probably should be considered in the context of the work that shredded itself once the auction was completed. You'd think twice about having your expensive "Banksy" authenticated after the fact by sending it away to parts unknown.
There's always someone dumb enough in the art world or someone who wants the story and has far too much money.
I quite like Banksy, tbh, but overexposure is a thing.
