Patent ID: 10630486

Abstract:
The present invention discloses a method and system for securing digital transactions provided by a person operating a third-party computerized device designed to communicate with a multiparty signing system. The multiparty signing system may comprise a signing subsystem comprising a multiparty signing server designed to receive a request for digital signing and a first subset of end-user nodes designed to generate a group of key shares which can be utilized in MPC processes conducted by the multiparty signing server. The multiparty signing system may also comprise an approving subsystem designed for generating groups of key shares to approve the digital transactions. The approving subsystem may comprise a coordinator and a second subset of end-user nodes for generating groups of key shares. The multiparty signing server may be configured to receive from a third-party server a transaction to sign and to send a first request to the coordinator to receive a first group of key shares.
