Abstract

A method of providing a service among heterogeneous services may include verifying whether a second web application associated with an external web service is installed in a user agent, when data of the external web service is requested from a first web application executed in the user agent, requesting key information to be used for accessing the requested data from a first server providing a web service associated with the first web application, when the second web application is installed in the user agent, receiving the key information from the first server, and accessing the requested data existing on the second web application, using the received key information, in the first web application.

Claims

1. A method of providing a service among heterogeneous services, the method comprising:

verifying whether a second web application associated with an external web service is installed in a user agent, when data of the external web service is requested from a first web application executed in the user agent;

requesting key information to be used for accessing the requested data from a first server providing a web service associated with the first web application, when the second web application is installed in the user agent;

receiving the key information from the first server; and

accessing the requested data existing on the second web application, using the received key information, in the first web application.

2. The method of claim 1, wherein the key information is generated by the second web application, transferred to a second server providing the external web service, and delivered from the second server to the first server at a request of the first server.

3. The method of claim 1, wherein the verifying comprises verifying whether the second web application is installed in the user agent, using a web application list provided by a web application manager included in the user agent.

4. The method of claim 3, wherein whether the web application list is to be provided by the web application manager is determined based on a user agreement.

5. The method of claim 1, wherein:

an indexed database (DB) is generated by the second web application, and

the key information is generated to correspond to data stored in the indexed DB.

6. A method of providing a service among heterogeneous services, the method comprising:

generating an indexed database (DB) in a first web application executed in a user agent;

confirming key information from the indexed DB and transmitting the confirmed key information to a first server providing a web service associated with the first web application; and

extracting data corresponding to the key information from the indexed DB and providing the extracted data to a second web application executed in the user agent, when the data is requested from the second web application using the key information.

7. The method of claim 6, wherein the key information is transferred from the first server to the second web application through a second server providing a web service associated with the second web application.

8. A user terminal for providing a service among heterogeneous services, the user terminal comprising:

a communication unit to communicate externally; and

a controller to execute a user agent,

wherein the user agent is configured to;

verify whether a second web application associated with an external web service is installed in the user agent, when data of the external web service is requested from a first web application executed in the user agent,

request key information to be used for accessing the requested data from a first server providing a web service associated with the first web application, when the second web application is installed in the user agent,

receive the key information from the first server, and

access the requested data existing on the second web application, using the received key information, through the first web application.

9. The user terminal of claim 8, wherein the key information is generated by the second web application, transferred to a second server providing the external web service, and delivered from the second server to the first server at a request of the first server.

10. The user terminal of claim 8, wherein the user agent verifies whether the second web application is installed in the user agent, using a web application list provided by a web application manager included in the user agent.

11. A user terminal for providing a service among heterogeneous services, the user terminal comprising:

a communication unit to communicate externally; and

a controller to execute a user agent,

wherein the user agent is configured to;

generate an indexed database (DB) in a first web application executed in the user agent,

confirm key information from the indexed DB and transmit the confirmed key information to a first server providing a web service associated with the first web application, and

extract data corresponding to the key information from the indexed DB and provide the extracted data to a second web application executed in the user agent, when the data is requested from the second web application using the key information.

12. The user terminal of claim 11, wherein the key information is transferred from the first server to the second web application through a second server providing a web service associated with the second web application.

13. A web server for providing a service among heterogeneous services, the web server comprising:

a communication unit to communicate with a user terminal; and

a controller,

wherein;

the controller is configured to receive, from the user terminal in which a first web application is installed, key information with respect to data stored in an indexed database (DB) of the first web application, manage the received key information, and transfer the key information corresponding to a request from an external server providing a web service associated with a second web application installed in the user terminal, and

the key information transferred to the external server is transferred to the user terminal and used for accessing the data stored in the indexed DB of the first web application, in the second web application.

14. A web server for providing a service among heterogeneous services, the web server comprising:

a communication unit to communicate with a user terminal; and

a controller,

wherein;

the controller is configured to request key information from an external server providing a web service associated with a second web application, receive the requested key information from the external server, and transfer the received key information to the user terminal, when the key information with respect to data stored in an indexed database (DB) of the second web application installed in the user terminal is requested from the user terminal in which a first web application is installed, and

the key information transferred to the user terminal is used for accessing the data stored in the indexed DB of the second web application, in the first web application.
