Abstract

The present disclosure relates to systems, methods, and computer-readable media for securely verifying an identity of a user of a client device based on a signal transmitted by the client device. For example, systems disclosed herein include registering a client device and facility device via a cloud computing system to enable the client device and facility device to securely communicate a signal via a wireless connection. The systems disclosed herein additionally include determining whether a trigger condition applies based on a position of the client device relative to the facility device. The systems disclosed herein further include maintaining and updating a subset of user verification information to include personal verification of a registered user of the client device. Using the subset of user verification information, a biometric scanning device may efficiently and accurately verify an identity of an individual associated with the client device.

First claim

1 . A method, comprising:
transmitting, from a first computing device, a beacon signal; receiving, by at the first computing device, a signal generated and broadcast by a second computing device in response to receiving the beacon signal from the first computing device, the signal including a value associated with the second computing device; detecting a trigger condition associated with proximity and direction of movement of the second computing device relative to the first computing device based on the signal transmitted by the second computing device; and based on detecting the trigger condition, decrypting the value from the signal using decryption information associated with the second computing device.

2 . The method of claim 1 , wherein the second computing device is a portable device transportable by a user carrying the second computing device.

3 . The method of claim 1 , wherein detecting the trigger condition includes determining that the second computing device is within a threshold distance of the first computing device, the threshold distance being determined based on a configured transmission power of an antenna on the first computing device.

4 . The method of claim 1 , further comprising receiving, at the first computing device, a second signal generated and broadcast by the second computing device in response to receiving the beacon signal, and wherein detecting the trigger condition includes determining a change in position between the first computing device and the second computing device based on differences in signal characteristics between the signal and the second signal.

5 . The method of claim 1 , wherein transmitting the beacon signal includes one or more of:
broadcasting the beacon signal to any of a number of computing devices within receiving distance of the first computing device: or broadcasting instances of the beacon signal at fixed intervals.

6 . The method of claim 1 , wherein detecting the trigger condition includes determining that the second computing device is both within a threshold distance of the first computing device and moving towards the first computing device.

7 . The method of claim 6 , further comprising receiving, at the first computing device, a second signal generated and broadcast by the second computing device in response to receiving the beacon signal, wherein detecting the trigger condition includes determining that a distance between the second computing device and the first computing device is decreasing based on differences in determined angles of arrival of the signal and the second signal transmitted by the second computing device.

8 . The method of claim 1 , wherein the decryption information is received at the first computing device when registering the second computing device with the first computing device.

9 . The method of claim 8 , wherein the decryption information is received from a cloud computing system acting as a broker between the first computing device and the second computing device.

10 . The method of claim 2 , further comprising, in response to detecting the trigger condition, causing the second computing device to engage an active state in which the second computing device transmits a plurality of signals at an elevated frequency relative to a frequency in which signals are transmitted prior to detecting the trigger condition.

11 . A system, comprising:
a processor; memory in electronic communication with the processor; and instructions stored in the memory, the instructions being executable to:
transmit, from a first computing device, a beacon signal;
receive, at the first computing device, a signal generated and broadcast by a second computing device in response to receiving the beacon signal from the first computing device, the signal including a value associated with the second computing device;
detect a trigger condition associated with proximity and direction of movement of the second computing device relative to the first computing device based on the signal transmitted by the second computing device; and
based on detecting the trigger condition, decrypt the value from the signal using decryption information associated with the second computing device.

12 . The system of claim 11 , wherein the second computing device is a portable device transportable by a user carrying the second computing device.

13 . The system of claim 11 , wherein detecting the trigger condition includes determining that the second computing device is within a threshold distance of the first computing device, the threshold distance being determined based on a configured transmission power of an antenna on the first computing device.

14 . The system of claim 11 , further comprising instructions being executable to receive, at the first computing device, a second signal generated and broadcast by the second computing device in response to receiving the beacon signal, and wherein detecting the trigger condition includes determining a change in position between the first computing device and the second computing device based on differences in signal characteristics between the signal and the second signal.

15 . The system of claim 11 , wherein transmitting the beacon signal includes one or more of:
broadcasting the beacon signal to any of a number of computing devices within receiving distance of the first computing device: or broadcasting instances of the beacon signal at fixed intervals.

16 . The system of claim 11 , wherein detecting the trigger condition includes determining that the second computing device is both within a threshold distance of the first computing device and moving towards the first computing device.

17 . The system of claim 16 , further comprising instructions being executable to receive, at the first computing device, a second signal generated and broadcast by the second computing device in response to receiving the beacon signal, wherein detecting the trigger condition includes determining that a distance between the second computing device and the first computing device is decreasing based on differences in determined angles of arrival of the signal and the second signal transmitted by the second computing device.

18 . The system of claim 11 , wherein the decryption information is received at the first computing device when registering the second computing device with the first computing device, and wherein the decryption information is received from a cloud computing system acting as a broker between the first computing device and the second computing device.

19 . The system of claim 11 , further comprising instructions being executable to, in response to detecting the trigger condition, cause the second computing device to engage an active state in which the second computing device transmits a plurality of signals at an elevated frequency relative to a frequency in which signals are transmitted prior to detecting the trigger condition.

20 . A non-transitory computer readable medium storing instructions thereon that, when executed, cause a first computing device to:
transmit, a beacon signal; receive a signal generated and broadcast by a second computing device in response to receiving the beacon signal from the first computing device, the signal including a value associated with the second computing device; detect a trigger condition associated with proximity and direction of movement of the second computing device relative to the first computing device based on the signal transmitted by the second comp
