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.
