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

What is claimed is:

1 . A method, comprising:
receiving, at a first device, registration information including a device identifier associated with a second device and decryption information, wherein the first device has access to a collection of entries including a plurality of device identifiers associated with a plurality of devices; transmitting, by the first device, a beacon signal to the second device that alerts the second device to a proximity between the first device and the second device; receiving, at the first device in response to the beacon signal, one or more signals transmitted by the second device, the one or more signals including a value associated with the device identifier, and wherein the decryption information enables the first device to decrypt the value from the signal and identify an entry from the collection of entries; and determining, based on the received signal transmitted by the second device, a trigger condition associated with the proximity between the first device and the second device.

2 . The method of claim 1 , wherein determining the trigger condition includes determining that the second device is within a threshold distance from the first device.

3 . The method of claim 1 , wherein the trigger condition is based on a directional position of the second device relative to a position of the first device.

4 . The method of claim 1 , wherein the trigger condition is based on movement of the second device relative to a position of the first device.

5 . The method of claim 1 , wherein determining the trigger condition includes determining that the second device is both within a threshold distance from the first device and that a distance between the first device and second device is decreasing.

6 . The method of claim 4 , further comprising determining that a distance between the first device and the second device is decreasing based on a determined angle of arrival of the one or more signals transmitted by the second device.

7 . The method of claim 1 , wherein the one or more signals includes multiple signals transmitted by the second device in response to the beacon signal, and wherein determining the trigger condition includes detecting a change in position between the first device and the second device based on differences in signal characteristics between subsequent transmissions of the multiple signals.

8 . The method of claim 7 , wherein the signal characteristics include one or more of:
signal strengths of the multiple signals transmitted by the second device; or angles of arrival of the multiple signals transmitted by the second device.

9 . The method of claim 1 , wherein transmitting the beacon signal includes broadcasting the beacon signal to any of a number of devices within receiving distance of the first device.

10 . The method of claim 9 , wherein transmitting the beacon signal includes broadcasting instances of the beacon signal at fixed intervals.

11 . The method of claim 1 , wherein the registration information is received from a cloud computing system based on registration of the first device and the second device.

12 . The method of claim 1 , further comprising causing, based on the trigger condition, the second device to engage an active state in which the second device transmits additional signals at more frequent time interval than one or more signals transmitted prior to engaging the active state.

13 . The method of claim 1 , further comprising, based on the trigger condition, identifying the entry from the collection of entries corresponding to the second device.

14 . The method of claim 13 , wherein the registration information includes user verification information, the user verification information including biometric data that may be compared to scanned biometric data obtained using a biometric scanning device to verify that a user of the second device corresponds to an identify of an individual associated with a corresponding value from the entry.

15 . A system, comprising:
one or more processors; memory in electronic communication with the one or more processors; and instructions stored in the memory, the instructions being executable by the one or more processors to cause a first device to:
receive registration information including a device identifier associated with a second device and decryption information, wherein the first device has access to a collection of entries including a plurality of device identifiers associated with a plurality of devices;
transmit a beacon signal to the second device that alerts the second device to a proximity between the first device and the second device;
receive, in response to the beacon signal, one or more signals transmitted by the second device, the one or more signals including a value associated with the device identifier, and wherein the decryption information enables the first device to decrypt the value from the signal and identify an entry from the collection of entries; and
determine, based on the received signal transmitted by the second device, a trigger condition associated with the proximity between the first device and the second device.

16 . The system of claim 15 , wherein the trigger condition is based on one or more of:
the second device being within a threshold distance from the first device; a directional position of the second device relative to a position of the first device; or movement of the second device relative to a position of the first device.

17 . The system of claim 15 , wherein the one or more signals includes multiple signals transmitted by the second device in response to the beacon signal, and wherein determining the trigger condition includes detecting a change in position between the first device and the second device based on differences in signal characteristics between subsequent transmissions of the multiple signals, the signal characteristics including one or more of:
signal strengths of the multiple signals transmitted by the second device; or angles of arrival of the multiple signals transmitted by the second device.

18 . The system of claim 15 , further comprising causing, based on the trigger condition, the second device to engage an active state in which the second device transmits additional signals at more frequent time interval than one or more signals transmitted prior to engaging the active state.

19 . A non-transitory computer readable medium storing instructions thereon that, when executed by one or more processors, causes a first computing device to:
receive registration information including a device identifier associated with a second device and decryption information, wherein the first device has access to a collection of entries including a plurality of device identifiers associated with a plurality of devices; transmit a beacon signal to the second device that alerts the second device to a proximity between the first device and the second device; receive, in response to the beacon signal, one or more signals transmitted by the second device, the one or more signals including a value associated with the device identifier, and wherein the decryption information enables the first device to decrypt the value from the signal and identify an entry from the collection of entries; and determine, based on the received signal transmitted by the second device, a trigger condition associated with the proximity between the first device and the second device.
