Abstract

Methods and systems for authentication of a device are disclosed. An exemplary method includes transmitting an energy towards the device including a material, monitoring a response of the device to the transmitted energy, generating a signature of the device based on the response of the device to the transmitted energy, comparing the device signature to an enrolled signature for the device, and indicating that authentication of the device is successful when the generated signature matches the enrolled signature. An exemplary system includes a transmitter configured to transmit an energy towards the device, a receiver configured to monitor a response of the device, and a processor configured to generate a signature of the device based on the response of the device, compare the device signature to an enrolled signature for the device, and indicate that authentication of the device is successful when the generated signature matches the enrolled signature.

Claims (61)

1. A method for authentication of a device comprising:

transmitting energy towards the device at an angle of incidence;

monitoring a response of the device to the energy transmitted towards the device at the angle of incidence;

generating a signature of the device based on:

the response of the device to the energy transmitted towards the device at the angle of incidence; and

an inclination of the device relative to a horizontal axis when the device is exposed to the energy transmitted towards the device at the angle of incidence;

comparing the device signature to an enrolled signature for the device; and

indicating that authentication of the device is successful when the generated signature matches the enrolled signature.

2. The method of claim 1 , wherein transmitting the energy towards the device comprises:

illuminating a surface of the device with a laser beam.

3. The method of claim 2 , wherein monitoring the response comprises:

capturing an image of the surface of the device.

4. The method of claim 1 , wherein transmitting the energy towards the device comprises:

emitting an electromagnetic signal.

5. The method of claim 4 , wherein monitoring the response comprises:

capturing an image of the surface of the device.

6. The method of claim 4 , wherein monitoring the response comprises:

receiving a resistance measurement from the device.

7. The method of claim 1 , further comprising:

receiving identification information for the device;

sending a request for the enrolled signature for the device to a database; and

receiving the enrolled signature from the database.

8. A system for authenticating a device comprising:

a transmitter configured to transmit energy towards the device at an angle of incidence;

a receiver configured to monitor a response of the device to the energy transmitted towards the device at the angle of incidence; and

a processor, coupled to the transmitter and the receiver, configured to:

generate a signature of the device based on:

the response of the device to the energy transmitted towards the device at the angle of incidence; and

an inclination of the device relative to a horizontal axis when the device is exposed to the energy transmitted towards the device at the angle of incidence;

compare the device signature to an enrolled signature for the device; and

indicate that authentication of the device is successful when the generated signature matches the enrolled signature.

9. The system of claim 8 , wherein the transmitter comprises a laser and the receiver comprises an image capture device.

10. The system of claim 8 , wherein the transmitter comprises an electromagnetic signal transmitter and the receiver comprises an image capture device.

11. The system of claim 8 , wherein the transmitter comprises an electromagnetic signal transmitter, and wherein the receiver is further configured to receive a resistance measurement from the device.

12. The system of claim 8 , further comprising:

a user interface module configured to receive identification information for the device.

13. A method for authentication of a device, the method comprising:

transmitting energy towards the device;

monitoring a response of the device to the transmitted energy at each of a plurality of angles of incidence;

generating a signature of the device based on:

the response of the device to the transmitted energy at each of the plurality of angles of incidence; and

an inclination of the device relative to a horizontal axis when the device is exposed to the transmitted energy;

comparing the device signature to an enrolled signature for the device; and

indicating that authentication of the device is successful when the generated signature matches the enrolled signature.

14. The method of claim 13 , wherein transmitting the energy towards the device comprises:

illuminating the surface of the device with a laser beam.

15. The method of claim 14 , wherein monitoring the response comprises:

capturing an image of the surface of the device.

16. The method of claim 13 , wherein transmitting the energy towards the device comprises:

emitting an electromagnetic signal.

17. The method of claim 16 , wherein monitoring the response comprises:

capturing an image of the surface of the device.

18. The method of claim 16 , wherein monitoring the response comprises:

receiving a resistance measurement from the device.

19. The method of claim 13 , further comprising:

receiving identification information for the device;

sending a request for the enrolled signature for the device to a database; and

receiving the enrolled signature from the database.

20. The system of claim 8 , wherein the processor is further configured to generate the signature of the device based on:

an intensity of the incident energy in the response, and

a type of the incident energy in the response.
