Abstract

How to allow requests and data, which are relevant to a service using an IC (Integrated Circuit), to be exchanged among a SAM unit serving as a data-processing apparatus, a server and the integrated circuit with a high degree of efficiency in an operation to render the service. The server transmits a first command requesting an IC module (the integrated circuit cited above) of a portable communication apparatus to carry out processing to the SAM unit. The SAM unit interprets the first command and transmits a second command for operating the IC module in accordance with a result of interpretation of the first command to the IC module by way of the server. The IC module carries out the processing in accordance with the second command and transmits a first response containing a result of the processing to the SAM unit by way of the server. If an outcome of the judgment formed on basis of the first response indicates that the above processing has been completed, the SAM unit transmits a second response indicating completion of the processing to the server.

Description

technical field [0001] The present invention relates to a data processing device and a data processing method for rendering services using an integrated circuit (IC), and to a program for realizing the data processing method. Background technique [0002] Currently, a communication system has been developed for realizing transaction processing through a network such as the Internet by utilizing an IC module incorporated in an IC card and a portable communication device. [0003] In such a communication system, a SAM (Security Application Module) unit executes an application program for realizing program processing prescribed by a service provider in response to a request from a service provider providing a service using an IC module. SAM units are typically connected to the network via servers. The communication between the SAM unit and the IC module is realized through the server and the network. The SAM unit realizes processing such as authenticating a user and encryptin...
