Abstract

The present teaching relates to method, system, medium, and implementations for detecting sensor tampering. Information is received from an inertial measurement unit (IMU) attached to a structure hosting at least one sensor. The information includes one or more measurements associated with the IMU. The at least one sensor is deployed on a vehicle for sensing surrounding information to facilitate autonomous driving. The one or more measurements are analyzed with respect to pre-determined criteria to detect tampering of the at least one sensor. When the tampering is detected, a response is generated to the event.

Claims (65)

1. A method implemented on at least one machine including at least one processor, memory, and communication platform for connecting to a network for detecting sensor tampering, the method comprising:

receiving, from an inertial measurement unit (IMU) attached to a structure hosting at least one sensor, information including one or more measurements associated with the IMU, wherein the at least one sensor is deployed on a vehicle for sensing surrounding information to facilitate autonomous driving;

analyzing the one or more measurements with respect to pre-determined criteria to detect tampering of the at least one sensor; and

generating, if the tampering is detected, a response to the tampering detected.

2. The method of claim 1 , wherein

the structure corresponds to a housing or a sensor rack with a plurality of sensors mounted thereon; and

the IMU and the structure are attached in such a way that they form a rigid integral structure.

3. The method of claim 1 , wherein the response is used to control performing at least one of:

triggering an alarm on the vehicle to produce a siren sound;

turning on selected sensors deployed on the vehicle to record information surrounding the tampering; and

transmitting signals to a remote site via network connection to report the tampering.

4. The method of claim 3 , wherein the signals transmitted to the remote site include an alert of the tampering and the information recorded by the selected sensors.

5. The method of claim 1 , wherein the step of analyzing comprises:

accessing a state of the vehicle;

determining whether a first of the one or more measurements is to be used to detect the tampering in the state of the vehicle;

comparing, if the first measurement is to be used to detect the tampering, the first measurement with the pre-determined criteria to detect the tampering.

6. The method of claim 5 , wherein

the state of the vehicle is one of a motion state and a parking state; and

the first measurement corresponds to a vibration measure set to be used to detect tampering if the vehicle is in a parking state.

7. The method of claim 6 , further comprising:

analyzing a second of the one or more measurements indicative of a pose of the IMU; and

determining the tampering based on the first and the second measurements.

8. Machine readable and non-transitory medium having information recorded thereon for detecting sensor tampering, wherein the information, when read by the machine, causes the machine to perform:

receiving, from an inertial measurement unit (IMU) attached to a structure hosting at least one sensor, information including one or more measurements associated with the IMU, wherein the at least one sensor is deployed on a vehicle for sensing surrounding information to facilitate autonomous driving;

analyzing the one or more measurements with respect to pre-determined criteria to detect tampering of the at least one sensor; and

generating, if the tampering is detected, a response to the tampering detected.

9. The medium of claim 8 , wherein

the structure corresponds to a housing or a sensor rack with a plurality of sensors mounted thereon; and

the IMU and the structure are attached in such a way that they form a rigid integral structure.

10. The medium of claim 8 , wherein the response is used to control performing at least one of:

triggering an alarm on the vehicle to produce a siren sound;

turning on selected sensors deployed on the vehicle to record information surrounding the tampering; and

transmitting signals to a remote site via network connection to report the tampering.

11. The medium of claim 10 , wherein the signals transmitted to the remote site include an alert of the tampering and the information recorded by the selected sensors.

12. The medium of claim 8 , wherein the step of analyzing comprises:

accessing a state of the vehicle;

determining whether a first of the one or more measurements is to be used to detect the tampering in the state of the vehicle;

comparing, if the first measurement is to be used to detect the tampering, the first measurement with the pre-determined criteria to detect the tampering.

13. The medium of claim 12 , wherein

the state of the vehicle is one of a motion state and a parking state; and

the first measurement corresponds to a vibration measure set to be used to detect tampering if the vehicle is in a parking state.

14. The medium of claim 13 , wherein the information, when read by the machine, further causes the machine to perform:

analyzing a second of the one or more measurements indicative of a pose of the IMU; and

determining the tampering based on the first and the second measurements.

15. A system for detecting sensor tampering, comprising:

an update controller configured for

receiving, from an inertial measurement unit (IMU) attached to a structure hosting at least one sensor, information including one or more measurements associated with the IMU, wherein the at least one sensor is deployed on a vehicle for sensing surrounding information to facilitate autonomous driving, and

analyzing the one or more measurements with respect to pre-determined criteria to detect tampering of the at least one sensor; and

a sensor special operation controller configured for generating, if the tampering is detected, a response to the tampering detected.

16. The system of claim 15 , wherein

the structure corresponds to a housing or a sensor rack with a plurality of sensors mounted thereon; and

the IMU and the structure are attached in such a way that they form a rigid integral structure.

17. The system of claim 15 , wherein the response is used to control performing at least one of:

triggering an alarm on the vehicle to produce a siren sound;

turning on selected sensors deployed on the vehicle to record information surrounding the tampering; and

transmitting signals to a remote site via network connection to report the tampering.

18. The system of claim 17 , wherein the signals transmitted to the remote site include an alert of the tampering and the information recorded by the selected sensors.

19. The system of claim 15 , wherein the step of analyzing comprises:

accessing a state of the vehicle;

determining whether a first of the one or more measurements is to be used to detect the tampering in the state of the vehicle;

comparing, if the first measurement is to be used to detect the tampering, the first measurement with the pre-determined criteria to detect the tampering.

20. The system of claim 19 , wherein

the state of the vehicle is one of a motion state and a parking state; and

the first measurement corresponds to a vibration measure set to be used to detect tampering if the vehicle is in a parking state.

21. The system of claim 20 , wherein a second of the one or more measurements indicative of a pose of the IMU is further analyzed and used, together with the first measurement, for determining the tampering.
