zero-knowledge proof
(cryptography) An interactive method for one party to prove to another that a (usually mathematical) statement is true, without revealing anything other than the veracity of the statement.
Non-interactive zero-knowledge proof
Non-interactive zero-knowledge proofs are cryptographic primitives, where information between a prover and a verifier can be authenticated by the prover, without revealing any of the specific information beyond the validity of the statement itself.
Zero-knowledge service
In cloud computing, the term zero-knowledge (or occasionally no-knowledge or zero access) refers to an online service that stores, transfers or manipulates data in a way that maintains a high level of confidentiality, where the data is only accessible to the data's owner (the client), and not to the service provider.
Zero-knowledge password proof
In cryptography, a zero-knowledge password proof is a type of zero-knowledge proof that allows one party (the prover) to prove to another party (the verifier) that it knows a value of a password, without revealing anything other than the fact that it knows the password to the verifier.
