Abstract

Provided are methods and apparatuses for providing contents via a network, in which original data of contents provided via a network can be traced, and contents that are modified according to performance of a contents receiving device is provided. Location information of original contents is added to metadata of contents provided via the network to thereby increase convenience of access to the original contents and modify attributes of contents that are provided, to be suitable for the performance of the contents receiving device.

Claims

1. A method of providing content, the method comprising:

storing, by a first device, an original content at a location and information identifying users who have access rights to the original content stored at the location;

sending, by a second device, an image associated with the original content along with both access information for allowing an authorized user to access the original content stored at the location and location information for identifying the location at which the original content is stored, to a third device used by a user;

receiving, by the first device, a request for the original content from the user, wherein the request is based on the location information and the access information for allowing the authorized user to access the original content stored at the location; and

determining, by the first device, whether to provide the original content as a response to the request, based on the request for the original content and the information identifying users who have access rights to the original content stored at the location.

2. The method of claim 1, wherein the original content is an image content, and

wherein the image associated with the original content comprises reduced image content having a resolution lower than a resolution of the original content.

3. The method of claim 1, wherein the original content is an image content, and

wherein the image associated with the original content comprises reduced image content having a file size smaller than a file size of the original content.

4. The method of claim 1, wherein the location information comprises a uniform resource locator (URL).

5. The method of claim 1, wherein the request comprises a request to access the location indicated by the location information.

6. The method of claim 1, wherein the sending comprises sending user information regarding a user of the image in addition to sending the image, the access information and the location information.

7. The method of claim 1, wherein the sending comprises sending editing history including information indicating format of the original content in addition to sending the image, the access information and the location information.

8. The method of claim 1, wherein the image is generated by modifying attributes of the original content.

9. The method of claim 1, wherein the location information for identifying the location sent by the second device is encoded.

10. A system for providing content, the system comprising:

a first device comprising at least one processor configured to control the first device to store an original content at a location and information identifying users who have access rights to the original content stored at the location; and

a second device comprising at least one processor configured to control the second device to send an image associated with the original content along with both access information for allowing an authorized user to access the original content stored at the location and location information for identifying the location at which the original content is stored, to a third device used by a user,

wherein the first device recieves a request for the original content from the user, the request being based on the location information and the access information for allowing the authorized user to access the original content stored at the location; and

wherein the first device determines whether to provide the original content as a response to the request, based on the request for the original content and the information identifying users who have access rights to the original content stored at the location.

11. The system of claim 10, wherein the original content is an image content, and

wherein a quality of the image associated with the original content is lower than a quality of the original content.

12. The system of claim 10, wherein the original content is an image content, and

wherein a resolution of the image associated with the original content is lower than a resolution of the original content.

13. The system of claim 10, wherein the original content is an image content, and

wherein a file size of the image associated with the original content is smaller than a file size of the original content.

14. The system of claim 10, wherein the location information comprises a uniform resource locator (URL).

15. The system of claim 10, wherein the request comprises a request to access the location indicated by the location information.

16. The system of claim 10, wherein the location information is a uniform resource locator (URL) indicating a storage path of the original content on the first device.

17. The system of claim 10, wherein the second device sends user information regarding a user of the image in addition to the image, the access information and the location information.

18. The system of claim 10, wherein the second device sends editing history including information indicating format of the original content in addition to the image, the access information and the location information.

19. The system of claim 10, wherein the image is generated by modifying attributes of the original content.

20. The system of claim 10, wherein the location information for identifying the location sent by the second device to the third device is encoded.

21. A non-transitory computer-readable recording medium having embodied thereon computer-readable codes, which, when executed by a system, cause the system to execute a method of providing content, the method comprising:

storing, by a first device, an original content at a location and information identifying users who have access rights to the original content stored at the location;

sending, by a second device, an image associated with the original content along with both access information for allowing an authorized user to access the original content stored at the location and location information for identifying the location at which the original content is stored, to a third device used by a user; and

recieving, by the first device, a request for the original content from the user, wherein the request is based on the location information and the access information for allowing the authorized user to access the original content stored at the location; and

determining, by the first device, whether to provide the original content as a response to the request, based on the request for the original content and the information identifying users who have access rights to the original content stored at the location.

22. The non-transitory computer-readable recording medium of claim 21, wherein the original content is an image content, and

wherein a resolution of the image associated with the original content is lower than a resolution of the original content.

23. The non-transitory computer-readable recording medium of claim 21, wherein the original content is an image content, and

wherein a file size of the image associated with the original content is smaller than a file size of the original content.

24. The non-transitory computer-readable recording medium of claim 21, wherein the location information comprises a uniform resource locator (URL).

25. The non-transitory computer-readable recording medium of claim 21, wherein the location information is a uniform resource locator (URL) indicating a storage path of the original content on the server.

26. The non-transitory computer-readable recording medium of claim 21, wherein the sending comprises sending user information regarding a user of the image in addition to sending the image, the access information and the location information.

27. The non-transitory computer-readable recording medium of claim 21, wherein the sending comprises sending editing history including information indicating format of the original content in addition to the image, the access information and the location information.

28. The non-transitory computer-readable recording medium of claim 21, wherein the image is generated by modifying attributes of the original content.

29. The non-transitory computer-readable recording medium of claim 21, wherein the location information for identifying the location sent by the second device is encoded.
