In an anonymous communication system, an anonymous property which a service provider requires and an anonymous property which a user permits are assured. A communication control apparatus 100 controls access from a user terminal 200 to a service apparatus 300 via an anonymous communication apparatus 410 based on service anonymous property information indicating an anonymous property for a user required by a service provider in a service provided with the service apparatus 300, anonymous communication ability information indicating an anonymous property of anonymous communication which the anonymous communication apparatus 410 is able to carry out, and user-granted information indicating an anonymous property for the user permitted by the user in communication between the user terminal 200 and the service apparatus 300. |
