Abstract

A method and apparatus for moving contents are discussed. According to an embodiment, the method includes determining whether or not a content is to be moved from a first device to a second device based on copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved; performing an authentication to authenticate the first and second devices with each other; and moving the content from the first device to the second device based on the determination result and the authentication result.

Claims

1. A method for moving contents, comprising:

determining whether or not a content is to be moved from a first device to a second device based on copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved;

performing an authentication to authenticate the first and second devices with each other; and

moving the content from the first device to the second device based on the determination result and the authentication result.

2. The method of claim 1, wherein the moving step moves the content from the first device to the second device, if the determining step determines that the content is to be moved and the performing step performs the authentication successfully.

3. The method of claim 2, wherein the moving step includes deleting the content from the first device.

4. The method of claim 1, wherein the moving step does not move the content from the first device to the second device, if the determining step determines that the content is not to be moved and/or the performing step does not perform the authentication successfully.

5. The method of claim 1, wherein the copy and movement control information is represented by three bits.

6. The method of claim 1, wherein the performing step performs the authentication by using at least one key value.

7. The method of claim 1, further comprising:

controlling a copying of the content based on the copy and movement control information.

8. A first device for moving contents, comprising:

a determination unit configured to determine whether or not a content is to be moved from the first device to a second device based on copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved; and

a control unit configured to perform an authentication to authenticate the first and second devices with each other, and to move the content from the first device to the second device based on the determination result and the authentication result.

9. The first device of claim 8, wherein the control unit is configured to move the content from the first device to the second device, if the determination unit determines that the content is to be moved and the control unit performs the authentication successfully.

10. The first device of claim 9, wherein the moving of the content includes deleting the content from the first device.

11. The first device of claim 8, wherein the control unit does not move the content from the first device to the second device, if the determination unit determines that the content is not to be moved and/or the control unit does not perform the authentication successfully.

12. The first device of claim 8, wherein the copy and movement control information is represented by three bits.

13. The first device of claim 8, wherein the control unit performs the authentication by using at least one key value.

14. The first device of claim 8, wherein the control unit is further configured to control a copying of the content based on the copy and movement control information.
