Multi-party computation cryptographic verification for authentication
Summary
USPTO published patent application US20260094156A1 for systems and methods using multi-party computation (MPC) for cryptographic verification and authentication. The invention involves generating partial signatures on multiple devices using distributed private key shares, aggregating signatures upon meeting a minimum threshold, and facilitating transaction processing on distributed ledgers.
What changed
The patent application discloses a system where a first device generates a partial signature using one of multiple private key shares distributed across different devices. The system receives additional partial signatures from other devices, verifies that the total meets or exceeds a minimum threshold, and aggregates all partial signatures to create a unified signature for transaction processing on a distributed ledger.
This patent application is informational and does not impose compliance obligations on regulated entities. Technology companies developing MPC-based authentication systems, blockchain applications, or multi-signature transaction systems should review the claims to assess potential licensing implications or freedom-to-operate considerations.

Abstract
Systems and methods are disclosed for security through multi-party computation (MPC). In some examples, a system generates, at a first device and using a first private key share (of a plurality of private key shares). The plurality of private key shares each correspond to different devices. The system receives, from one or more additional devices, one or more additional partial signatures that are generated using one or more additional private key shares (of the plurality of private key shares). The system identifies that a total amount of partial signatures associated with the transaction is meets or exceeds a minimum threshold amount of partial signatures. The system aggregates the first partial signature and the one or more additional partial signatures to generate a signature, and facilitates processing of a transaction using the signature and a distributed ledger.
