Building security system

摘要

A security system includes a central computer connected through a network to a plurality of remote computers. A database of user information is created at the central computer and copied to the remote computers. The remote computers include user interfaces for the collection of user information such a fingerprint and a user ID. When a user provides this information, the remote computer compares it to the database. If a match is generated, the remote computer authorizes access through an associated passageway. The security system can also be used to monitor user access times and to present messages to users.
