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