Document Type and Number:
Japanese Patent JP2022158677
Kind Code:
A
Abstract:
To realize a technique capable of implementing a certification service with higher user convenience or reducing the risk of leakage of privacy information.SOLUTION: A device is one of a plurality of devices participating in a multi-party computation on which a protocol for performing zero-knowledge proof in secret-sharing-based multi-party computation is implemented, and includes acquisition means for acquiring a share of data relating to a matter to be proved, and output means for outputting an output share obtained as a result of performing calculation according to a protocol with the acquired share as an input. It is possible to verification in zero-knowledge proof by output shares collected from a plurality of devices participating in a multi-party computation.SELECTED DRAWING: Figure 1
