SECURITY MANAGEMENT METHOD IN A DECENTRALIZED DATA BASE SYSTEM.

摘要

A security management method of terminals and data base in a decentralized data base system. The object is to further improve reliability of security for terminals and data base, and to grant access by a user by a method simpler than conventional ones and in an easy-to-use flexible form. To achieve this, the present invention provides a system comprising means for controlling terminals in groups, for setting a terminal for group management, and for reinforcing and making flexible the security by multiplexing the permission conditions of access to the terminals and to the data base with respect to a password and the like.
