Abstract: An input for designating sent-out contents capable of being browsed on a provider-side processing apparatus is accepted. Ticket information for identifying a sending-party of sent-out contents is received from the provider-side processing apparatus. The sent-out contents and the ticket information are transmitted to a deliberation support processing apparatus to request a deliberation about the sent-out contents. The sent-out contents and the ticket information are stored into a deliberation managing database. An input of a deliberation result of the requested deliberation is accepted to store the deliberation result into the deliberation managing database. The ticket information is transmitted to a ticket management processing apparatus. Presentation of personal information on the sending-party is requested. The personal information on the sending-party identified by the ticket information is transmitted to the deliberation support processing apparatus.

Abstract: In an access control method for use with a system including a client, a www server, and a ticket granting server, the www server has a server policy defining an access allowance condition and sends a server policy to the client having requested an access. The ticket granting server obtains, in response to a request and the server policy sent from the client, personal information from a personal information database, authenticates the personal information, and sends it as a ticket to the client. The client sends an access request with the ticket to the www server. The www server allows the client the access when the ticket matches the server policy.
