Abstract

Provided are a method for attaching a geographical tag to digital data and a method for providing geographical name information for geotagging. When a digital device periodically provides its position information, the server creates a position database. When the digital device requests geographical name information associated with the digital data, the server estimates the position of the digital device at a time when the digital data was created and transmits geographical name information corresponding to the estimated position to the digital device. The digital device attaches the geographical name information to the digital data.

Claims

1. A method for geotagging a digital data, the method comprising the steps of:

periodically providing geographic position information of a digital device to a server by the digital device so that the server creates, position database based on the geographic position information;

creating digital data by the digital device;

requesting the server to provide geographical name information associated with the digital data based on the geographic position information of the digital device;

receiving the geographical name information from the server; and

associating the geographical name information to the digital data.

2. The method of claim 1, wherein the step of periodically providing the geographic position information includes the step of providing the geographic position information through an idle-screen service.

3. The method of claim 1, wherein the geographical name information includes a plurality of geographical names.

4. The method of claim 3, wherein the step of associating the geographical name information includes the step of providing to a user a pointing service capable of selecting at least one among the plurality of geographical names.

5. The method of claim 1, further comprising the step of providing a manual input service for allowing a user to input a user-inputted geographical name associated with the digital data if the geographical name information received from the server does not include a desired geographical name.

6. The method of claim 5, further comprising the step of transmitting the user-inputted geographical name to the server, wherein, if the digital device requests the server to provide the geographical name information associated with the digital data, the server transmits the geographical name information together with the user-inputted geographical name.

8. The method of claim 1, wherein the geographic position information and a time at which the digital device provides, the geographic position information to the server are recorded in the position database.

9. The method of claim 8, wherein, in case the time at which the digital device provides the geographic position information to the server is different from a time at which the digital device requests the server to provide the geographical name information associated with the digital data, a position of the digital device at a time t_m is determined by a function of f(t_k) and f(t_k+1) in which t_k and t_k+1 denote times at which the digital device provides the geographic information, the times t_k and t_k+1 being adjacent to the time t_m at which the digital device requests the server to provide the geographical name information, and f(t_k) and f(t_k+1) denote positions of the digital device at the times t_k and t_k+1, respectively.

10. The method of claim 9, wherein the position of the digital device at the time t_m is determined by interpolation using f(t_k) and f(t_k+1).

11. The method of claim 9, wherein the position of the digital device is determined to be f(t_k) in case t_m is nearer to t_k+1 than to t_k+1 or f(t_k+1) in case t_m is nearer to t_k+1 than to t_k.

13. The method of claim 1, wherein the geographic position information is provided not at regular intervals of time but at variable intervals of time and the geographic position information is provided to the server by manually manipulating the digital device.

15. A method for providing geographical name information for geotagging, the method comprising the steps of:

periodically receiving geographic position information of a digital device from the digital device by a server, and creating a position database based on the geographic position information;

upon receiving a request for geographical name information associated with digital data from the digital device, retrieving the geographical name information associated with the digital data based on the geographic position information of the digital device; and

transmitting the retrieved geographical name information to the digital device.

16. The method of claim 15, wherein the geographic position information and a time at which the digital device provides the geographic position information are recorded in the position database.

17. The method of claim 15, wherein the step of retrieving the geographical name information includes:

estimating a position of the digital device based on a time at which the server receives the request for geographical name information; and

retrieving the geographical name information corresponding to the estimated position.

18. The method of claim 15, further comprising the step of receiving a user-inputted geographical name, which is manually inputted by a user as a tag for the digital data, wherein, if the server is requested to provide the geographical name information associated with the digital data by the digital device, the server transmits the geographical name information together with the user-inputted geographical name.

20. The method of claim 15, wherein the digital device provides the geographic position information to the server through an idle-screen service.

21. The method of claim 15, wherein the geographic position information and a time at which the server receives the geographic position information from the digital device are recorded in the position database.

22. The method of claim 21, wherein, in case the time at which the server receives the geographic position information from the digital device is different from a time at which the server is requested to provide the geographical name information associated with the digital data by the digital device, a position of the digital device at a time t_m is determined by a function of f(t_k) and f(t_k+1), in which t_k and t_k+1 denote times at which the digital device provides the geographic information, the times t_k and t_k+1 being adjacent to the time t_m at which the digital device requests the server to provide the geographical name information, and f(t_k) and f(t_k+1) denote positions of the digital device at the times t_k and t_k+1, respectively.

23. The method of claim 21, wherein the position of the digital device at the time t_m is determined by interpolation using f(t_k) and f(t_k+1).

24. The method of claim 21, wherein the position of the digital device is determined to be f(t_k) in case t_m is nearer to t_k than to t_k+1 or f(t_k+1) in case t_m is nearer to t_k+1 than to t_k.

26. The method of claim 15, wherein the geographic position information is received not at regular intervals of time but at variable intervals of time and the server receives the geographic position information which is manually inputted by manipulating the digital device.

28. One or more computer-readable media having stored thereon a computer program that, when executed by one or more processors, causes the one or more processors to perform acts including:

periodically providing geographic position information of a digital device to a server by the digital device so that the server creates a position database based on the geographic position information;

creating digital data by the digital device;

requesting the server to provide geographical name information associated with the digital data based on the geographic position information of the digital device;

receiving the geographical name information from the server; and

associating the geographical name information to the digital data.
