Abstract

An example of adaptive location perturbation can include selecting, by a processing resource of a mobile device executing instructions stored on a non-transitory medium, between a plurality of localization technologies to perturb a location measurement of the mobile device. The perturbed location measurement of the mobile device can be sent to a location-based service provider.

First claim

What is claimed:

1. A method for adaptive location perturbation, comprising:
selecting, by a processing resource of a mobile device executing instructions stored on a non-transitory medium, between a plurality of localization technologies to perturb a plurality of locations measured by the mobile device;
smoothen a directional transition of the mobile communication device by smoothening at least one of the perturbed locations to create a smoothened perturbed trajectory; and
sending the smoothened perturbed trajectory and the perturbed location measurements of the mobile device to a location-based service provider.

2. The method of claim 1 , wherein selecting between the plurality of localization technologies comprises adaptively selecting between localization technologies that have differing magnitudes of location measurement error.

3. The method of claim 2 , wherein selecting between the plurality of localization technologies comprises context-aware selecting to increase perturbation of the location measurement of the mobile device in a selected location.

4. The method of claim 3 , wherein selecting between the plurality of localization technologies comprises increasing a magnitude of the location measurement perturbation in the selected location.

5. The method of claim 3 , wherein selecting between the plurality of localization technologies comprises increasing a probability of a location measurement in the selected location by a localization technology having a relatively high magnitude of location measurement error.

6. The method of claim 1 , comprising adaptively switching between the plurality of localization technologies to perturb at least one of the plurality of locations measured by the plurality of localization technologies during transit of a trajectory by the mobile device.

7. The method of claim 1 , comprising controlling at least one of a frequency of adaptively switching between the plurality of localization technologies and a frequency of sending a location measurement of the mobile device to the location-based service provider to mitigate incurred communication costs.

8. A system for adaptive location perturbation, comprising:
a mobile communication device comprising;
a processing resource; and
a memory resource communicatively coupled to the processing resource, the memory resource storing machine-readable instructions executable by the processing resource to;
adaptively switch between a plurality of localization technologies to perturb a plurality of location measurements of the mobile communication device;
smoothen a directional transition of the mobile communication device by smoothening at least one of the perturbed locations to create a smoothened perturbed trajectory; and
transmit the smoothened perturbed trajectory and the perturbed location measurements of the mobile communication device to a location-based service provider.

9. The system of claim 8 , wherein the mobile communication device comprises a profile adaptively adjustable for location measurement perturbation in selected mapped areas to achieve a balance between the perturbation and quality of service for the mobile communication device.

10. The system of claim 8 , wherein the mobile communication device comprises a profile adaptively adjustable to vary a percent chance of selection of at least one of the plurality of localization technologies for measurement of the location of the mobile communication device in at least one selected mapped area.

11. The system of claim 8 , comprising a feedback functionality to present a record of unperturbed and perturbed location measurements of the mobile communication device and to enable adaptive adjustment of at least one of preceding perturbations and succeeding perturbations.

12. The system of claim 8 , wherein each of the plurality of localization technologies have differing magnitudes of location measurement error.

13. The system of claim 8 , wherein adaptively switching between the plurality of localization technologies comprises context-aware switching to increase perturbation of the location measurement of the mobile communication device in a selected location.

14. A non-transitory machine-readable medium storing program instructions for adaptive location perturbation, the instructions being executable by a processing resource to:
enable a mobile communication device to adaptively switch between a plurality of localization technologies to perturb at least one of a plurality of locations measured by the plurality of localization technologies during transit of the mobile communication device;
smoothen a directional transition of the mobile communication device by smoothening at least one perturbed location to create a smoothened perturbed trajectory; and
transmit the smoothened perturbed trajectory and the plurality of measured locations transited by the mobile communication device to a device of a location-based service provider.

15. The medium of claim 14 , comprising to probabilistically select between the plurality of localization technologies for at least one location measurement based upon an adaptively assigned percent chance that each of the localization technologies will be selected.

16. The medium of claim 14 , comprising to simulate a potential adversary map-matching the smoothened perturbed trajectory transmitted by the mobile communication device to determine efficacy of perturbation of the at least one of the plurality of locations in reduction of an ability to accurately map-match an actual transited trajectory.

17. The medium of claim 14 , wherein each of the plurality of localization technologies have differing magnitudes of location measurement error.

18. The medium of claim 14 , wherein adaptively switching between the plurality of localization technologies comprises context-aware switching to increase perturbation of the location measurement of the mobile device in a selected location.

19. The medium of claim 18 , wherein adaptively switching between the plurality of localization technologies comprises increasing a magnitude of the location measurement perturbation in the selected location.

20. The medium of claim 18 , wherein adaptively switching between the plurality of localization technologies comprises increasing a probability of a location measurement in the selected location by a localization technology having a relatively high magnitude of location measurement error.
