A communication control apparatus that controls communication via a network between a first communication apparatus for communicating via a virtual communication channel and a second communication apparatus for transmitting a communication request with the first communication apparatus including a storage unit that stores access control policy defining allowance or denial of access to the first communication apparatus, an establishment unit that establishes the virtual communication channel with the first communication apparatus, an authentication unit that authenticates the second communication apparatus based on the communication request received from the second communication apparatus, an access control unit that refers to the access control policy and evaluates whether to allow or deny access from the authenticated second communication apparatus to the first communication apparatus, and a transfer unit that transfers the received communication request to the first communication apparatus when the access control unit evaluates that the access is allowed.

In a TCP/UDP communication system, a communication process begins with a receipt of a communication request from an application program that does not specify a predetermined communication parameter such as source port number. A port number is dynamically assigned to the communication request. The communication process is then suspended and communication control data associated with the application program is supplemented with the assigned source port number to generate supplemented communication control data. The communication process is then resumed to establish communication over a communications network, and the established communication is controlled according to the supplemented communication control data.

The service terminalwhich contains bar code reader, RF-ID readerand information processing block is moved to a medium containing the bar code and RF-ID tag. Both of the bar code readerand RF-ID readerare set to the positions that information can be read from the bar code and RF-ID tag. In this case, the information processing block controls the bar code readerand RF-ID readerto read information from the bar code and RF-ID tag.

Before providing a software body I, a determination program I is prepared to determine whether a software body II should be authenticated for combination and use with the software body I, and is provided with the software body I. A platform executes the determination program I before the platform employs the software body I with the software body II, and only when the determination results represent the permission for combination and use, the platform permits the software II to be combined and used with the software body I.
