    摘要: A relay device 12 is provided which transfers a plurality of original data fragments corresponding to a plurality of secret sharing values of original data to a plurality of secure computation devices, transfers, to each of the secure computation devices, a request to send a result fragment based on a secure computation result corresponding to any one of the original data fragments, and transfers the result fragment. The relay device 12 controls timing with which the original data fragments are transferred and timing with which the request to send is transferred.

    摘要: Data processing is performed while personal information is kept concealed. A registrant terminal 2 splits a registration input password and allocates the split pieces to secure computation servers 1. The secure computation servers 1 verify whether the password matches. The registrant terminal 2 splits target data and allocates the data shared values to the secure computation servers 1. The secure computation servers 1 store the data shared values. A user terminal 3 splits a utilization input password and allocates the split pieces to the secure computation servers 1. The secure computation servers 1 verify whether the password matches. The user terminal 3 sends a data processing request to the secure computation servers 1. The secure computation servers 1 execute secure computation of the data shared values to generate processing result shared values. The user terminal 3 recovers the processing result from the processing result shared values.
