Multiparty Signing System for Secure Digital Transaction Approval

The patent segments the authorization process into distinct phases: key generation phase where multiple parties create key shares, transaction initiation phase where a transaction is proposed, and approval phase where multiple parties independently approve or reject the transaction. This segmentation allows the system to maintain security through distributed key shares while adding versatility through the approval mechanism that enables control and oversight of transactions.

The patent introduces an intermediary approval mechanism that acts as a mediator between the multi-signature requirement and transaction execution. The approval subsystem, comprising multiple approvers, serves as an intermediary layer that can validate, approve, or reject transactions before they are finalized, thereby adding control capability without compromising the underlying security of the multi-signature system.

The patent segments the authorization function across multiple independent entities including key generators, approvers, and the transaction system. Rather than relying on a single central authority, the system divides the authorization process into discrete segments performed by different parties, maintaining decentralization while collectively achieving reliable transaction control through the requirement of multiple approvals.

The patent merges multiple decentralized authorization mechanisms into a unified approval system. By combining the multi-signature requirement with the approval subsystem, the system achieves both decentralization (through distributed key shares and multiple approvers) and reliable transaction control (through the combined effect of signature requirements and approval validation).
