System and method for authenticating user based on path location

1. A passive authenticating system, comprising:

a multiple of locks, each of which includes a wireless transmitter; and

a mobile device in communication with at least one of the multiple of locks, the mobile device including a transceiver and a processor, wherein the mobile device processor and transceiver are configured to:

receive an emission map from one of the multiple of locks;

determine a path trajectory of a user in relation to the emission map of a security region to authenticate the user based at least in part on the path trajectory of the user wherein the mobile device determines the path trajectory via identification of signals received from the multiple of locks, then permit passive access to a particular lock of the multiple of locks in response to the authentication of the user, wherein emission data from the multiple of locks generates the emission map for a secure region, the path trajectory is associated with one or more of the multiple of locks

transmit authentication information to the one of the multiple of locks;

wherein the one of the multiple of locks is configured to permit passive access to the lock as the mobile device approaches the lock.

2. The system as recited in claim 1 , wherein the identification is performed by a magnetometer on the mobile device.

3. The system as recited in claim 1 , wherein the identification is performed by a sensor on the mobile device that determines a signal strength from one or more of the multiple of locks.

4. The system as recited in claim 1 , wherein the mobile device is operable to determine the path trajectory via an accelerometer on of the mobile device.

5. The system as recited in claim 1 , wherein the mobile device is operable to determine the path trajectory based at least in part on a received signal strength indicator (RSSI) on the mobile device.

6. The system as recited in claim 1 , wherein the mobile device is operable to determine the path trajectory at least in part on a Wi-Fi signal strength on the mobile device.

7. The system as recited in claim 1 , wherein the mobile device is operable to determine the path trajectory via a gyroscope on of the mobile device.

8. The system as recited in claim 1 , wherein the path trajectory is associated with a time.

9. The system as recited in claim 1 , wherein the mobile device is a smartphone.

10. A method of passively authenticating a user, comprising:

receiving, by a mobile device, an emission map transmitted wirelessly from a transceiver within one of a multiple of locks;

determining a path trajectory of a user in relation to the emission map of a security region, wherein the mobile device of the user determines the path trajectory via identification of signals received from one or more of a multiple of locks and the path trajectory is associated with one or more of the multiple of locks;

authenticating, by the mobile device, the user in response to the path trajectory;

transmitting, by the mobile device, authenticating information to the one of the multiple locks;

permitting, by the one of the multiple of locks, passive access to a lock in response to the authenticating information as the mobile device approaches the lock.

11. The method as recited in claim 10 , wherein determining the path trajectory of the user is performed at least in part by a magnetometer on the mobile device.

12. The method as recited in claim 10 , wherein determining the path trajectory of the user is performed at least in part by an accelerometer on the mobile device.

13. The method as recited in claim 10 , wherein determining the path trajectory of the user is performed at least in part by a received signal strength indicator (RSSI) on the mobile device.

14. The method as recited in claim 10 , wherein determining the path trajectory of the user is performed at least in part by a Wi-Fi signal strength on the mobile device.

15. The method as recited in claim 10 , wherein authenticating the user in response to the path trajectory comprises matching the path trajectory of the user with a predetermined path trajectory of the user.

16. The method as recited in claim 10 , wherein authenticating the user in response to the path trajectory comprises matching the path trajectory of the user with a predetermined path trajectory of the user within a particular time frame.

17. The method as recited in claim 10 , wherein permitting passive access to the lock in response to the authenticating comprises passively submitting a credential to an electromechanical lock to unlock it, and thereby gain access to a restricted area.
