Reply to comment by KustyTheKlown in I painted Jersey City with watercolor by majozaur

This area is new to me so I find it really interesting. In yo7r bag example, how do you keep the physical bag indisputably paired with the digital token to guarantee its authenticity? In other words, why couldn’t I just counterfeit the bag with the same physical characteristic (whatever that may be) that points to the same digital token?

Off the top of my head - instead of a hard serial number in the bag, a dynamic one - for example, to sign into that jpmc job, I had a keychain that generated a 6 digit code which changed every few minutes. Something like that could change in real time with the digital token of authenticity to validate the pairing

Thanks for the response!

Yeah, I’ve used things like that for 2 factor authentication when connecting to work networks remotely. But I’m not sure if I can see that working in this scenario - if I steal the dongle I can now associate any bag with the token while also making the authentic bag valueless.

I’d think the actual bag itself would need to unalterably be connected to the token. Like, if this were science fiction, I’d have some unique ID encoded into the bags fabric at the molecular level or something like that.

Or am I missing something?

You aren’t missing anything, and I generally leave it to people smarter than me to work this stuff out. There are kinks but I also think legit use cases once the kinks are sorted
