More Information
Summary:In a secret sharing storage system (5), when hospital data (OD) is received from a hospital terminal (HI), a main controller (10) distributedly processes the hospital data (OD) using a physical random number generated by a random number generator (20) and generates n distributed data (H1D1-H1Dn), and stores these in n corresponding share holders (S1-Sn), respectively. The main controller (10) acquires the n distributed data (H1D1-H1Dn) respectively stored in the n share holders (S1-Sn) in accordance with a restore indication of the hospital terminal (HI). The main controller (10) restores the hospital data (OD) from the n distributed data (H1D1-H1Dn) using a physical random number and sends the restored data to the hospital terminal (HI).
