A personal identification system includes local computer systems to be operated by authorized users, a remote computer system having common resources (data, hardware, etc.) to be accessed from the local computer systems, and a personal verification system having a database section which stores passwords of each authorized user and physical characteristics data corresponding to each password. When a user made a request to a local computer system for the use of the common resources of the remote computer system, physical characteristics (a fingerprint etc.) of the user is scanned by a scanning section of the local computer system, and characteristics data generated based on the scanned physical characteristics is sent to the personal verification system. The personal verification system searches the database section for a password using the received characteristics data as a key, and sends the searched password to the local computer system. The local computer system which received the password sends the password to the remote computer system for personal identification of the user. Passwords of the authorized users are managed solely by the personal verification system, thereby the user is allowed to make access to the common resources of the remote computer system easily and freely without the need of memorizing and inputting a complicated password.
