2. The method according to claim 1, wherein the first sensor information includes position information of the first mobile object detected by the first mobile object.

3. The method according to claim 2, wherein determining whether a first mobile object among the plurality of mobile objects is a real mobile object includes determining whether the first mobile object is a real mobile object based on an estimation error of the first sensor information.

4. The method according to claim 3, further comprising:

determining an estimated position of the first mobile object by matching the position information of the first mobile object with geographic data, determining whether a first mobile object among the plurality of mobile objects is a real mobile object comprises calculating the estimation error of the first sensor information from a position corresponding to the position information of the first mobile object and the estimated position.

5. The method according to claim 4, further comprising:

acquiring a normal error range associated with the position of the first mobile object, wherein determining whether a first mobile object among the plurality of mobile objects is a real mobile object includes determining that the first mobile object is not a real mobile object, on a condition that the estimation error of the first sensor information is outside the normal error range.

6. The method according to claim 5, further comprising:

storing the normal error range for every position in the geographic space in a context database, based on an estimation error of position information detected by at least one mobile object among the plurality of mobile objects based on the at least one mobile object having moved in the geographic space.

7. The method according to claim 6, wherein storing the normal error range for every position in the geographic space comprises independently storing information for each of at least one of:

a type of the at least one mobile object, a model of the at least one mobile object, and a condition of the position.

8. The method according to claim 2, wherein

determining whether a first mobile object among the plurality of mobile objects is a real mobile object includes determining that the first mobile object is not a real mobile object, in response to a position of the first mobile object overlapping at the same timing with a position of a second mobile object among the plurality of mobile objects.

9. The method according to claim 2, wherein determining whether a first mobile object among the plurality of mobile objects is a real mobile object includes determining whether the first mobile object is a real mobile object based on a result of a comparison between behavior of the first mobile object and behavior of a second mobile object positioned within a predetermined distance of and on the same route as the first mobile object among the plurality of mobile objects.

10. The method according to claim 2, wherein determining whether a first mobile object among the plurality of mobile objects is a real mobile object includes determining that the first mobile object is a real mobile object, in response to the first mobile object being detected at a position corresponding to the position information of the first mobile object according to a sensor provided in the geographic space or in a second mobile object among the plurality of mobile objects.

11. The method according to claim 2, further comprising:

requesting that a second mobile object among the plurality of mobile objects checks whether the first mobile object is present at a position corresponding to the position information of the first mobile object in response to a judgment that the first mobile object is possibly not a real mobile object.

12. The method according to claim 1, wherein the information processing includes performing information processing relating to mobile object agents corresponding respectively to the plurality of mobile objects.

13. The method according to claim 1, wherein determining whether a first mobile object among the plurality of mobile objects is a real mobile object further comprises:

identifying whether the first mobile object is a virtual mobile object that has been registered in advance; and

determining whether the first mobile object is a real mobile object based on determining that the first mobile object is identified as not being a virtual mobile object.

14. A computer program product for management of a movement of mobile objects, the computer program product comprising:

a computer-readable storage device and program instructions stored on computer-readable storage device, the program instructions comprising;
