摘要

An information management system is provided that can safely store and manage user-related information while improving user-friendliness. An encryption key is generated by a cell phone (20) from a password and identification information, confidential information is encrypted using the encryption key and then transmitted to a server device (30), and the encryption key is discarded. When a user tries to acquire the confidential information, the encryption key is again generated from the password and identification information, the encrypted confidential information is read from the server device (30), and then the encrypted confidential information is decoded using the encryption key generated by a terminal unit (20).
