Abstract
To enable effective use of other information while keeping personal information confidential.SOLUTION: Original data including personal information is pseudonymized and encrypted, and transmitted to a service providing device. For pseudonymization and encryption, hashing is performed using a torque character string for each client. The service providing device transmits information after service processing to a user terminal. The information after service processing can be used without a risk of leakage of personal information and attribute information to the outside. When necessary, the information after service processing can be utilized by matching and restoring it using personal information held by the user terminal and key information obtained from the outside.SELECTED DRAWING: Figure 1
