I'd like it if there was a centralized shared secret system available from the following sources: my credit union, my local & state govt, and the fed govt. I'd like to be able to set an arbitrary K-of-N recovery with an additional S "individual" recoverers. I don't mind it being publicly available (it's encrypted!); maybe 16KB for the whole account?
This is because it'd be a way for people to establish identity: let a third party write to my shared account, and I can prove I own it by decrypting the message.
The govt aspect is to prove who I am & establish residence for things like voting, DL#s, birth certificate recovery, passports...
- thworp 3y agoThe state part is a pipe dream except in a few specific countries. In some countries nobody would actually trust the system, some simply lack the ressources or educated gov workers to run it. In most rich countries the bureaucrat-industrial-complex (including the national software consultants) would fight tooth and nail against a system that deprives them of sweet sweet taxpayer money. OTOH I'd say Switzerland, Estonia and Costa Rica could actually get it done.
- Sjlver 3y agoAlas, psst can't help with that. With psst (or indeed any secret sharing scheme), there is a single secret which is only split while at rest. In order to actually make use of the secret, it needs to be recovered from the shares. Your use-case would probably use other techniques, such as multi-signature schemes, multiparty computation, and zero knowledge proofs. Decentralized identity management is a difficult problem.
