Prediction of flight path privacy

1. A method of predicting an achievable level of privacy of a flight path, the method comprising:

receiving, by a computer comprising a processor and memory, an indication of a flight route of an aircraft;

receiving, by the computer, an indication of one or more privacy enhancement techniques;

estimating, by the computer, an air traffic density for one or more airspaces along or near the flight route, the estimating based on information obtained from one or more aviation information databases;

estimating, by the computer, an achievable level of privacy of the flight path based, at least in part, on the air traffic density for one or more airspaces and the one or more privacy enhancement techniques; and

outputting, to a display communicatively coupled to the computer, an indication of the estimated achievable level of privacy.

2. The method of claim 1 , further comprising:

using the estimated achievable level of privacy of the flight path as a privacy layer in one or more flight planning and optimization problems.

3. The method of claim 1 , further comprising:

receiving an indication of aircraft information of the aircraft, wherein estimating the achievable level of privacy of the flight path is further based, at least in part, on the aircraft information.

4. The method of claim 1 , wherein estimating the achievable level of privacy of the flight path is further based, at least in part, on at least a portion of the information obtained from the one or more aviation information databases.

5. The method of claim 1 , wherein the information obtained from the one or more aviation information databases comprises air traffic information from an air traffic database.

6. The method of claim 1 , wherein the information obtained from the one or more aviation information databases comprises airspace system information from an airspace system database.

7. The method of claim 1 , wherein the one or more privacy enhancement techniques comprises a technique that includes updating an identifier of the aircraft.

8. The method of claim 7 , wherein the technique further includes at least one of an identifier update, a random silent period, using a mix airspace, or a group update.

9. A system of predicting an achievable level of privacy of a flight path, the system comprising:

a user input module configured to receive an indication of a flight route of an aircraft and an indication of one or more privacy enhancement techniques;

a privacy computation module configured to:

estimate, based on information obtained from one or more aviation information databases, an air traffic density for one or more airspaces along or near the flight route, and

estimate an achievable level of privacy of the flight path based, at least in part, on the air traffic density for one or more airspaces and the one or more privacy enhancement techniques; and

a user output module configured to output an indication of the estimated achievable level of privacy.

10. The system of claim 9 , wherein the privacy computation module is configured to communicate with the one or more aviation information databases via a network.

11. The system of claim 9 , wherein the system is located on the aircraft.

12. The system of claim 11 , wherein the aircraft comprises one or more pre-loaded updated identifiers.

13. The system of claim 9 , wherein the system is located in a ground-based station.

14. The system of claim 13 , wherein the ground-based station is configured to transmit an output of the user output module to the aircraft.

15. The system of claim 14 , wherein the ground-based station is configured to transmit an updated aircraft identifier to the aircraft with the output of the user output module.

16. A method of predicting a flight privacy enhancement opportunity, the method comprising:

receiving, by a computer comprising a processor and memory, an indication of a flight route of an aircraft;

receiving, by the computer, an indication of one or more privacy enhancement techniques;

estimating, by the computer, an air traffic density for one or more airspaces along or near the flight route, the estimating based on information obtained from one or more aviation information databases;

estimating, by the computer, an achievable level of privacy of the flight route based, at least in part, on the air traffic density for one or more airspaces;

predicting, by the computer, a flight privacy enhancement opportunity based, at least in part, on the air traffic density, the estimated achievable level of privacy of the flight route, and the one or more privacy enhancement techniques; and

displaying, on a display communicatively coupled to the computer, an indication of the estimated achievable level of privacy.

17. The method of claim 16 , wherein the flight privacy enhancement opportunity is located in one of the one or more airspaces.

18. The method of claim 17 , wherein the one or more privacy enhancement techniques comprise a technique that includes updating an identifier of the aircraft in the one of the one or more airspaces.

19. The method of claim 16 , wherein predicting the flight privacy enhancement opportunity comprises predicting a plurality of flight privacy enhancement opportunities located along or near the flight route.

20. The method of claim 16 , further comprising:

displaying the flight route overlayed on a representation of a geographical area; and

displaying the flight privacy enhancement opportunity overlayed on the representation of the geographical area.
