Abstract

Disclosed are a smart card-based browsing system, a smart card-based browsing method, and smart card for the same. A browser is installed in the smart card to form a direct connection path with an SCWS installed in the smart card. The number of sockets for HTTP request/response required to be as many as the number of contents for services between the smart card and the user terminal is reduced, so that the services can be smoothly provided through a rapid and effective interface. A web service can be provided to various multimedia appliances compatible with the smart card regardless of the existence of the browser on the user terminal and the type and version of the browser.

Claims

1. A smart card-based browsing system comprising:

a user terminal receiving a driving signal according to execution of an application embedded in a smart card from the smart card through a driving interface for controlling at least one device resource mounted in the user terminal to drive the at least one device resource; and

the smart card forming a connection path with an SCWS (Smart Card Web Server) through a browser embedded in the smart card in response to request of the user terminal through the driving interface to execute the application based on the SCWS, and sending the driving signal according to the execution of the application to the user terminal to drive the at least one device resource.

2. A user terminal comprising:

a card interface module forming a driving interface used to communicate with a smart card, connecting to a browser embedded in the smart card through the driving interface to request execution of an application, and receiving a driving signal according to execution of the application from the smart card; and

a device driving module receiving the driving signal through the card interface module and driving at least one embedded device resource based on the driving signal.

3. The user terminal of claim 2, wherein the card interface module connects to the browser embedded in the smart card through the driving interface based on a USB (Universal Serial Bus) protocol to request the execution of the application.

4. The user terminal of claim 3, wherein the card interface module connects to an SCWS provided in the smart card based on an HTTP (Hypertext Transfer Protocol) through the browser to request the execution of the application based on the SCWS.

5. A smart card comprising:

a terminal interface module forming a driving interface for controlling at least one device resource mounted in a user terminal;

a browser requesting execution of an embedded application according to request of the user terminal through the driving interface and sending a driving signal according to the execution of the application to the user terminal through the driving interface to drive the at least one device resource; and

an application driving module executing the application according to the request of the execution of the application through the browser and sending the driving signal according to the execution of the application to the browser.

6. The smart card of claim 5, wherein the terminal interface module sends the driving signal according to the execution of the application to the user terminal through the driving interface based on a USB protocol.

7. The smart card of claim 5, wherein the application driving module is an SCWS forming a connection path with the browser based on an HTTP and executes the application based on the SCWS according to the request of the execution of the application through the browser.

8. A smart card-based browsing method comprising:

requesting, by a user terminal, execution of an application to a smart card through a driving interface for controlling at least one device resource mounted in the user terminal;

establishing, by the smart card, a connection path with an SCWS through a browser embedded in the smart card according to the request of the user terminal through the driving interface;

executing, by the smart card, the application through the SCWS;

sending, by the smart card, the driving signal according to the execution of the application to the user terminal through the driving interface; and

driving, by the user terminal, at least one device resource based on the driving signal received through the driving interface.

9. A smart card-based browsing method comprising:

connecting to a browser embedded in a smart card through a driving interface used to communicate with the smart card;

requesting execution of an application driven on the smart card through the browser;

receiving a driving signal according to the execution of the application from the smart card through the driving interface; and

driving at least one device resource based on the received driving signal.

10. The method of claim 9, wherein the connecting connects to the browser embedded in the smart card through the driving interface based on a USB protocol.

11. The method of claim 9, wherein the requesting requests the execution of the application based on the SCWS by connecting to an SCWS provided in the smart card based on HTTP through the browser.

12. A smart card-based browsing method comprising:

receiving an execution request of an application embedded in a smart card from a user terminal through a driving interface for controlling at least one device resource mounted in the user terminal;

executing the application through a browser embedded in the smart card according to the request of the user terminal; and

sending a driving signal according to the execution of the application to the user terminal through the driving interface to drive the at least one device resource.

13. The method of claim 12, wherein the executing executes the application based on the SCWS by forming a connection path with an SCWS embedded in the smart card based on HTTP through the browser.

14. The method of claim 12, wherein the sending sends the driving signal according to the execution of the application to the user terminal through the driving interface based on a USB protocol.

15. A computer-readable recording medium comprising computer readable code to control at least one processing device to implement a smart card-based browsing method comprising:

connecting to a browser embedded in a smart card through a driving interface used to communicate with the smart card;

requesting execution of an application driven on the smart card through the browser;

receiving a driving signal according to the execution of the application from the smart card through the driving interface; and

driving at least one device resource based on the received driving signal.

16. A computer-readable recording medium comprising computer readable code to control at least one processing device to implement a smart card-based browsing method comprising:

receiving an execution request of an application embedded in a smart card from a user terminal through a driving interface for controlling at least one device resource mounted in the user terminal;

executing the application through a browser embedded in the smart card according to the request of the user terminal; and

sending a driving signal according to the execution of the application to the user terminal through the driving interface to drive the at least one device resource.
