Abstract

An access control system comprising a reader configured to make an ingress or egress determination using information received from one or more mobile devices is described. The reader may be further configured to store information about ingress and egress events for analysis by a system administrator.

Claims

1. A method, for use in an access control reader controlling access to a protected physical asset, for making an ingress or egress determination with an access control system, the method comprising:

identifying, with a processor and based on information received via a wireless interface of an access control reader, a plurality of mobile devices within communication range of the access control reader;

receiving first information from at least one of the plurality of mobile devices, the first information corresponding to a first distance between at least two of the plurality of mobile devices;

receiving second information from at least one of the plurality of mobile devices, the second information corresponding to a second distance between at least two of the plurality of mobile devices; and

making an ingress or egress determination for a user of at least one of the plurality of mobile devices with respect to the protected physical asset based on the first information and the second information.

2. The method of claim 1, further comprising:

storing the ingress or egress determination in a memory of the access control reader;

generating an access point profile based on a plurality of stored ingress or egress determinations from the memory of the access control reader; and

transmitting the access point profile from the access control reader.

3. The method of claim 1, wherein making the ingress or egress determination comprises comparing the first distance with the second distance.

4. The method of claim 1, wherein making the ingress or egress determination comprises calculating a change in distance over time based on the first distance and the second distance and comparing the change in distance over time to third information stored in a memory of the access control reader.

5. The method of claim 1, wherein the first information comprises RSSI information or time-of-flight information.

6. The method of claim 1, wherein making the ingress or egress determination is further based on information corresponding to muscle expansion or contraction.

7. An access control reader controlling access to a protected physical asset, comprising:

a processor;

a wireless communication interface; and

a memory storing instructions that, when executed by the processor, cause the processor to;

identify, with the processor and based on information received via the wireless communication interface, a plurality of mobile devices within communication range of the wireless communication interface;

receive first information from at least one of the plurality of mobile devices, the first information corresponding to a first distance between at least two of the plurality of mobile devices;

receive second information from at least one of the plurality of mobile devices, the second information corresponding to a second distance between at least two of the plurality of mobile devices; and

make an ingress or egress determination for a user of at least one of the plurality of mobile devices with respect to the protected physical asset based on the first information and the second information.

8. The access control reader of claim 7, wherein making the ingress or egress determination comprises evaluating, based on the first information and the second information, a variation over time of a distance between two of the plurality of mobile devices.

9. The access control reader of claim 7, wherein at least one of the first information and the second information comprises RSSI or time-of-flight information.

10. The access control reader of claim 9, wherein the memory stores additional instructions that, when executed by the processor, cause the processor to:

calculate at least one of the first distance and the second distance using the RSSI or time-of-flight information.

11. The access control reader of claim 7, wherein making the ingress or egress determination is further based on information about muscle expansion or contraction.

12. The access control reader of claim 7, wherein at least one of the first information and the second information further comprises acceleration information.

13. The access control reader of claim 7, wherein making the ingress or egress determination comprises comparing the first information or the second information with other information stored in the memory.

14. The access control reader of claim 13, wherein the other information stored in the memory comprises information about a relative distance between at least two of the plurality of mobile devices during an ingress event.

15. The access control reader of claim 7, further comprising a wired or wireless transmitter, and wherein the memory stores additional instructions that, when executed by the processor, further cause the processor to:

store the ingress or egress determination in the memory; and

send the ingress or egress determination to a predetermined computing device via the transmitter.

16. The access control reader of claim 7, wherein making the ingress or egress determination comprises comparing the first distance with the second distance.

17. The access control reader of claim 7, wherein the reader further comprises a lock control mechanism, and the memory stores additional instructions that, when executed by the processor, further cause the processor to:

operate the lock control mechanism based on the ingress or egress determination.

18. A system for controlling access to a protected physical asset, comprising:

a first mobile device;

a second mobile device; and

an access control reader, the access control reader comprising;

a processor;

a wireless communication interface;

a memory storing instructions that, when executed by the processor, cause the processor to;

verify, with the processor and based on information received via the wireless communication interface, that the first mobile device and the second mobile device are within communication range of the wireless communication interface;

receive first information from at least one of the first mobile device and the second mobile device, the first information corresponding to a first distance between the first mobile device and the second mobile device;

receive second information from at least one of the first mobile device and the second mobile device, the second information corresponding to a second distance between the first mobile device and the second mobile device; and

make an ingress or egress determination for a user of at least one of the first mobile device and the second mobile device based on the first information and the second information.

19. The mobile device of claim 18, wherein at least one of the first information and the second information comprises RSSI information or time-of-flight information.

20. The mobile device of claim 18, wherein the first information is received from the first mobile device, and the first information comprises sensor information from a sensor of the first mobile device.
