Title:
セキュアマルチパーティ計算を使用したプライバシー保持測定
Document Type and Number:
Japanese Patent JP7425222
Kind Code:
B2
Abstract:
This document relates to using secure MPC to select digital components in ways that preserve user privacy and protects the security of data of each party that is involved in the selection process. In one aspect, a method includes performing, by a first server of a secure MPC system in collaboration with one or more second servers of the secure MPC system, a selection process to select a digital component based in part on a selection value for each digital component in the selection process. This includes determining a first secret share of a winner parameter for each digital component in the selection process. The first server determines, for each given digital component in the selection process and in collaboration with the second server(s), a highest other selection value that corresponds to a different digital component that is different from the given digital component.
