Hi!

Curious, if i there tool\site with wich i could verify for example 1 of 100 physically printed books?

Each one book - unique public key (100 books = 100 keys, printed on backside of it) wich could be verify by one private key

It just and idea in mind, but, maybe there any ready solution? Many public keys chain-linked with one master key - are just for example

Thank you

can you explain what you mean? what do you mean by verify? the contents integrity(a checksum)? the ability to confirm it was not modified once distributed (Public key cryptography e.g. PGP)? something else?
