Summary: | An equipment manager (31) manages the operating state of equipment. A user verification processor (32) performs user verification according to a request from a monitoring terminal, and when user verification is successful, generates for each facility management device (3) a verification code in which verification data, to which a digital signature has been added using a self-owned secret key (111), has been encoded using a public key of each facility management device (3), and transmits the verification codes to the monitoring terminal. A verification code analyzer (33), after receiving the verification code that was generated for the own device facility management device (3) from the monitoring terminal, decodes the verification code using the self-owned secret key (111), and performs verification by verifying the digital signature using the public key of a representative facility management device (3). When verification by the user verification processor (32) or verification code analyzer (33) is successful, a Web server (34) is able to monitor and manipulate data that indicates the operating states of all of the equipment that is managed by the equipment manager (31). |
