In a secret sharing storage system (5), when hospital data (OD) is received from a hospital terminal (H1), 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 (H1). 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 (H1). 在秘密共享存储系统(5)中，当从医院终端(H1)接收到医院数据(OD)时，主控制器(10)使用由随机数生成器(20)生成的物理随机数来分布式地处理医院数据(OD)，并生成n个分布式数据(H1D1-H1Dn)，并且将这些数据分别存储在n个相应的共享保持器(S1-Sn)中。根据医院终端(H1)的恢复指示，主控制器(10)获取分别存储在n个共享保持器(S1-Sn)中的n个分布式数据(H1D1-H1Dn)。主控制器(10)使用物理随机数根据n个分布式数据(H1D1-H1Dn)来恢复医院数据(OD)，并且将恢复的数据发送到医院终端(H1)。
