  • Patent number: 8850186
    Abstract: An information processing apparatus that communicates using an electronic certificate is provided. When identification information is configured that identifies the information processing apparatus on a network, the configured identification information is stored in a storage unit. A request for issue of an electronic certificate containing the identification information stored in the storage unit is issued to a certificate authority. Once the request for issue is issued, a determination is made as to whether or not the identification information contained in the request for issue matches the identification information stored in the storage unit prior to obtaining the electronic certificate that is issued by the certificate authority in response to the request for issue. If it is determined that a mismatch exists, the user is notified to that effect.

  • Patent number: 7987375
    Abstract: If electronic certificate data containing a private key and public key to be used to add an electronic signature to data with timer transmission setting is deleted, no electronic signature can be added at the set timer transmission time. To accomplish this, when timer transmission and electronic signature addition using stored key information and electronic certificate are set for transmission target data (YES in S38), deletion of the stored key information and electronic certificate to be used for generating an electronic signature is restricted (S40).

  • Patent number: 7930375
    Abstract: A service providing apparatus which, even when there is a change in the contents of service provided for terminal devices, enables the terminal devices to register the changed contents of the service in a reliable manner. Upon the start of the service providing apparatus or the service, the service providing apparatus gives the terminal devices a service end notification for nullifying the contents of service registered in the terminal devices. After the service end notification is given, the service providing apparatus gives a service start notification to the terminal devices, and notifies the contents of service to the terminal devices in response to an acquisition request issued from any terminal device based on the service start notification.
