  • Patent number: 7487920
    Abstract: An integrated circuit card operation management system and method are provided. In one example of the system, a collator system is provided for receiving a user request to determine whether the application program can be loaded, for acquiring a card policy from a card issue management system, and for acquiring an application program policy from a service provider management system. The collator system requests card related information of the card issue management system and requests application program related information of the service provider management system. The collator system specifies a definition format. The card issue management system and the service provider management system extract requested information from existent information, convert the requested information according to the specified definition format, and transmit the converted information to the collator system.

  • Patent number: 7360088
    Abstract: A system is provided which compensates a low operational performance of a conventional integrated circuit (IC) card by setting a substitute server computer between the IC card and a business server computer in a system using the IC card. Substitute processing using an authentication result is realized by setting an IC card authentication server computer in addition to the business server computer and sending an authentication result of the authentication server computer to the IC card, substitute server computer, and business server computer. Thus, because the substitute server computer does not directly authenticate the IC card, the quantity of authentication information in the substitute server computer is substantially reduced and authentication processing becomes efficient.
