Passive multi-factor access control with biometric and wireless capability
Described are systems and methods for providing an authorized user access to a restricted area using a combination of biometric identification factors, such as facial feature recognition, and wireless detection of a device associated with the authorized user.
1. A system for controlling access of a user to an area, the system comprising
an operable barrier to entry to the area;
a closure device configured to operate the barrier to prevent or allow entry of the user to the area;
a detector configured to wirelessly detect a device associated with an authorized user;
a biometric capture device configured to capture a biometric characteristic of the user;
a memory; and
a processor configured to
receive data associated with the detection of a device associated with the authorized user from the detector and the biometric characteristic of the user from the biometric capture device;
determine the proximity of the device associated with the authorized user to the detector and the time of detection of the device associated with the authorized user;
compare the captured biometric characteristic to a stored characteristic of the authorized user stored in the memory; wherein the stored characteristic of the authorized user comprises an encoded and encrypted data string transformed by a facial feature mapping template and algorithm from an image of the authorized user;
determine that the captured biometric characteristic matches that of the authorized user;
determine that the proximity of the device associated with the authorized user to the detector and the biometric characteristic of the authorized user indicate the presence of the authorized user at the operable barrier; and
instruct the closure device to operate the barrier to allow the authorized user to access the area.
2. The system of claim 1 wherein the biometric characteristic of the user comprises facial features of the user.
3. The system of claim 1 wherein the captured biometric characteristic of the user comprises an encoded and encrypted data string transformed by a facial feature mapping template and algorithm from an image of the user.
4. The system of claim 3 wherein the captured biometric characteristic is compared to the stored characteristic of the authorized user stored in the memory.
5. The system of claim 3 wherein the data string transformed by the facial feature mapping template and algorithm from the image of the authorized user is encoded, encrypted and stored in memory on the device associated with the authorized user.
6. The system of claim 5 wherein the data associated with the detection of a device associated with the authorized user comprises the encoded, encrypted data string.
7. The system of claim 1 wherein the data associated with the detection of a device associated with the authorized user comprises a security code assigned to the authorized user.
8. The system of claim 1 wherein the processor is further configured to determine that the presence of the authorized user at the operable barrier is at a time at which the authorized user is permitted to access the area.
9. The system of claim 1 further comprising machine learning algorithms to improve efficacy of the determination that the captured biometric characteristic matches that of the authorized user.
10. The system of claim 1 wherein the processor is further configured to determine that adverse conditions prevent accurate capture of the biometric characteristic of the user and provide output to instruct the access control point to notify the user that the biometric characteristic was not captured.
11. A method for controlling access of a user to an area, the method comprising
detecting a device associated with an authorized user;
capturing a biometric characteristic of the user;
determining the proximity of the device associated with the authorized user to the detector and the time of detection of the device associated with the authorized user;
comparing the captured biometric characteristic to a characteristic of the authorized user stored in the memory, wherein the stored characteristic of the authorized user comprises an encoded and encrypted data string transformed by a facial feature mapping template and algorithm from an image of the authorized user;
determining that the captured biometric characteristic matches that of the authorized user;
determining that the proximity of the device associated with the authorized user to the detector and the biometric characteristic of the authorized user indicate the presence of the authorized user at the operable barrier; and
instructing a closure device to operate a barrier to allow the authorized user to access the area.
12. The method of claim 11 wherein the biometric characteristic of the user comprises facial features of the user.
13. The method of claim 11 wherein the captured biometric characteristic of the user comprises an encoded and encrypted data string transformed by a facial feature mapping template and algorithm from an image of the user; and wherein the captured biometric characteristic is compared to the stored characteristic of the authorized user.
14. The method of claim 11 wherein the data associated with the detection of a device associated with the authorized user comprises a security code assigned to the authorized user.
15. The method of claim 11 further comprising the processor determining that the presence of the authorized user at the operable barrier is at a time at which the authorized user is permitted to access the area.
16. A non-transitory computer readable medium having computer readable instructions stored thereon, that when executed by a computer cause at least one processor to
receive data associated with the detection of a device associated with the authorized user from the detector and the biometric characteristic of the user from the biometric capture device;
determine the proximity of the device associated with the authorized user to the detector and the time of detection of the device associated with the authorized user;
compare the captured biometric characteristic to a stored characteristic of the authorized user stored in the memory; wherein the stored characteristic of the authorized user comprises an encoded and encrypted data string transformed by a facial feature mapping template and algorithm from an image of the authorized user;
determine that the captured biometric characteristic matches that of the authorized user;
determine that the proximity of the device associated with the authorized user to the detector and the biometric characteristic of the authorized user indicate the presence of the authorized user at the operable barrier; and
instruct the closure device to operate the barrier to allow the authorized user to access the area.
17. The non-transitory computer readable medium of claim 16 wherein the biometric characteristic of the user comprises facial features of the user.
18. The non-transitory computer readable medium of claim 16 wherein the captured biometric characteristic of the user comprises an encoded and encrypted data string transformed by a facial feature mapping template and algorithm from an image of the user; and wherein the instructions cause the processor to compare the captured biometric characteristic to the stored characteristic of the authorized user.
19. The non-transitory computer readable medium of claim 16 wherein the data associated with the detection of a device associated with the authorized user comprises a security code assigned to the authorized user.
20. The non-transitory computer readable medium of claim 16 further comprising instructions to cause the processor to determine that the presence of the authorized user at the operable barrier is at a time at which the authorized user is permitted to access the area.
