Title:
SECRET CALCULATION METHOD, SECRET CALCULATION SYSTEM, SECRET CALCULATION SERVER, REGISTRANT TERMINAL, USER TERMINAL AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/114947
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a secret calculation method whereby data processing is carried out while personal information is kept confidential. A registrant terminal (2) distributes registration entry passwords to secret calculation servers (1) via secret sharing. The secret calculation servers (1) verify whether or not the passwords match. The registrant terminal (2) distributes data to be processed to the secret sharing servers (1) via secret sharing. The secret calculation servers (1) store the data shares. A user terminal (3) distributes utilization entry passwords to the secret calculation servers (1) via secret sharing. The secret calculation servers (1) verify whether or not the passwords match. The user terminal (3) transmits a data processing request to the secret calculation servers (1). The secret calculation servers (1) carry out secret calculation on the data shares to create shares for processing results. The user terminal (3) combines the shares for processing results to obtain the processing results.
