  • Patent number: 10740425
    Abstract: A content administration system receives user identification information from a terminal device via the Internet. The content administration system then specifies content administration information storage means corresponding to the received user identification information. The content administration system acquires object path information correlated to sharing permission information from a content administration information storage means of another unspecified user. The content administration system then acquires an icon image from the icon image storage means. The content administration system then makes display control information for the content administration screen containing the icon leading to the object based on the acquired icon image and the acquired object path information. The content administration system transmits the made display control information to the terminal device via the Internet.

  • Patent number: 10715666
    Abstract: While using a communication system in which groups of destinations on a network are managed, and any one of the groups can be specified as a destination, if a group needs to be changed, added, or deleted, updating the system on the network is required, which increases load of maintenance. To address such a problem, an operation input receiving unit of a terminal receives selection of a group including destination information that represents destination candidates of communication. A destination management unit of the terminal determines a destination among the destination candidates represented by the destination information included in the selected group. A sending and receiving unit of the terminal makes a request for starting communication with the determined destination, to a management system.
