US Patent 11394550 Systems and methods providing specialized proof of confidential knowledge

Systems and methods for verifying proofs generated from shared data without revealing the shared data are provided. In one aspect, a method comprises receiving, from a first node, a first proof generated from a first private key associated with the first node and data shared between the first node and a second node; receiving, from the second node, a second proof generated from a second private key associated with the second node and the shared data; verifying, without revealing the shared data, the first proof and the second proof were both generated from the shared data with a first public key mathematically related to the first private key, and a second public key mathematically related to the second private key; and preforming an action based on the verification of the first proof and the second proof both being generated from the shared data.
