Claims

means for obtaining virtual reality content embedded with watermark information;
means for playing back the virtual reality content with the watermark information canceled, comprising:
The program according to claim 1, wherein the watermark information is obtained by reversibly converting at least part of information of the virtual reality content.

causing the computer to further execute means for acquiring at a predetermined timing a reference position associated with the coordinate system of the virtual reality content;
2. The program according to claim 1, wherein said reproducing means cancels said watermark information embedded at a position associated with said reference position.

causing the computer to further execute means for acquiring offset information associated with the reference position at a predetermined timing;
3. The program according to claim 2, wherein said reproducing means cancels said watermark information embedded at a position offset from said reference position based on said offset information.

4. The program according to claim 3, wherein the offset position changes as the reproduction time of the virtual reality content elapses.

causing the computer to further execute means for acquiring cancellation information regarding a method for canceling the watermark information at a predetermined timing;
5. The program according to any one of claims 1 to 4, wherein said reproducing means cancels said watermark information based on said cancellation information.

The computer further comprises means for acquiring, at a predetermined timing, cancellation information relating to a plurality of cancellation methods for canceling the watermark information and designation information specifying a specific cancellation method among the plurality of cancellation methods. let it run,
5. The program according to any one of claims 1 to 4, wherein said reproducing means cancels said watermark information by said specific cancellation method based on said cancellation information and said designation information.

7. The program according to claim 6, wherein said designation information changes as the reproduction time of said virtual reality content elapses.

8. The program according to any one of claims 1 to 7, wherein said watermark information is embedded in said virtual reality content at a position or size that does not hinder browsing of said virtual reality content.

9. The virtual reality content according to any one of claims 1 to 8, wherein a plurality of pieces of said watermark information are embedded at intervals narrower than a display area of an image display device on which said virtual reality content is displayed. program.

10. The program according to any one of claims 1 to 9, wherein said watermark information is embedded in said virtual reality content in a predetermined shape for indicating the authentic origin of said virtual reality content.

The program according to claim 1, wherein the watermark information is obtained by reversibly converting at least part of information of the virtual reality content.

causing the computer to further execute means for distributing a reference position associated with the coordinate system of the virtual reality content at a predetermined timing;
13. The program according to claim 12 , wherein said watermark information is embedded at a position associated with said reference position.

causing the computer to further execute means for distributing offset information associated with the reference position at a predetermined timing;
14. The program according to claim 13 , wherein said watermark information is embedded at a position associated with said offset information.

15. The program according to claim 14 , wherein said offset information changes as the reproduction time of said virtual reality content elapses.

16. The program according to any one of claims 12 to 15 , further causing said computer to execute means for distributing cancellation information regarding a method for canceling said watermark information at a predetermined timing.

The computer is further provided with means for delivering, at a predetermined timing, cancellation information relating to a plurality of cancellation methods for canceling the watermark information and designation information specifying a specific cancellation method among the plurality of cancellation methods. 16. A program according to any one of claims 12 to 15 , to be executed.

18. The program according to claim 17 , wherein said designation information changes as the reproduction time of said virtual reality content elapses.

19. The program according to any one of claims 12 to 18 , wherein said watermark information is embedded in said virtual reality content at a position or size that does not hinder browsing of said virtual reality content.

20. The virtual reality content according to any one of claims 12 to 19 , wherein a plurality of pieces of said watermark information are embedded at intervals narrower than a display area of an image display device on which said virtual reality content is displayed. program.
