Systems and methods for authenticating a user using an image capture device
A user authentication system includes an image capture device and a controller communicatively coupled to the image capture device. The controller receives first image data associated with user identification information and generates a first set of biometric data based on the first image data. The controller also receives second image data associated with a first user action in response to the first set of biometric data approximately matching a first set of authenticated biometric data. The controller further generates a second set of biometric data based on the second image data and receives third image data associated with a second user action. The controller also generates a third set of biometric data based on the third image data. The controller further grant access to a user account in response to the second and third sets of biometric data approximately matching second and third sets of authenticated biometric data, respectively.

identify a second plurality of biomechanical points in a second frame of the plurality of frames, wherein the second plurality of biomechanical points comprises a second position of the digit, the appendage, the head, or combination thereof, associated with a second gesture in the video data captured by the image capture device;
receive an authenticated gesture sequence; and
grant access to a user account based on determining that the first gesture and the second gesture correspond to the authenticated gesture sequence.

4 . The user authentication system of claim 1 , wherein the one or more processors are configured to deny access to the user account based on:
the first gesture not correlating to a first authenticated gesture of the authenticated gesture sequence or the second gesture not correlating to a second authenticated gesture of the authenticated gesture sequence; and
determining that a threshold number of access requests has been exceeded.
5 . The user authentication system of claim 1 , wherein the first gesture is different than the second gesture.
6 . The user authentication system of claim 1 , wherein the one or more processors are configured to:
generate a set of biometric data based on the video data captured by the image capture device; and
grant access to the user account based on determining that the first gesture and the second gesture correspond to the authenticated gesture sequence and the set of biometric data correlates to authenticated biometric data.
7 . The user authentication system of claim 1 , wherein the one or more processors are configured to:
request authentication information; and
grant access to the user account based on determining that the first gesture and the second gesture correspond to the authenticated gesture sequence and the authentication information correlates to an authenticated user.
8 . The user authentication system of claim 7 , wherein the authentication information comprises a password, a personal identification number, or any combination thereof.
9 . The user authentication system of claim 1 , wherein the one or more processors are configured to request performance of a first body movement to define the first gesture.
10 . The user authentication system of claim 1 , wherein the one or more processors are configured to request performance of a second body movement associated with the second plurality of biomechanical points to define the second gesture.
11 . The user authentication system of claim 1 , wherein the one or more processors are configured to request confirmation of whether the video data is acceptable prior to attempting to determine that the first gesture and the second gesture correspond to the authenticated gesture sequence.
12 . A method comprising:
receiving, with one or more processors, video data captured by an image capture device, wherein the video data comprises a plurality of frames;
identifying, with one or more processors, a plurality of biomechanical points in a first frame of the plurality of frames, wherein the first plurality of biomechanical points is associated with a first gesture in the video data captured by the image capture device, wherein the plurality of biomechanical points comprises a first position of a digit, an appendage, a head, or any combination thereof;
identifying, with one or more processors, the plurality of biomechanical points in a second frame of the plurality of frames, wherein the second plurality of biomechanical points comprises a second position of the digit, the appendage, the head, or any combination thereof, associated with a second gesture in the video data captured by the image capture device;
receiving, with one or more processors, an authenticated gesture sequence; and
granting, with one or more processors, access to a user account based on determining that the first gesture and the second gesture correspond to the authenticated gesture sequence.
13 . The method of claim 12 , comprising:
prompting, with the one or more processors, the user to perform an action using an electronic display.
14 . The method of claim 13 , wherein the action comprises entering a keystroke on a keyboard, having a fingerprint read, drawing a pattern on a trackpad, speaking a code phrase, or any combination thereof.
15 . The method of claim 12 , comprising:
prompting, with the one or more processors, provision of the video data as a login identification and provision of the video data as a passcode.
16 . One or more tangible, non-transitory, machine-readable media comprising instructions configured to cause one or more processors to:
receive video data captured by an image capture device, wherein the video data comprises a plurality of frames;
identify a plurality of biomechanical points in a first frame of the plurality of frames, wherein the first plurality of biomechanical points is associated with a first gesture in the video data captured by the image capture device, wherein the plurality of biomechanical points comprises a first position of a digit, an appendage, a head, or any combination thereof, of the user;
identify the plurality of biomechanical points in a second frame of the plurality of frames, wherein the second plurality of biomechanical points comprises a second position of the digit, the appendage, the head, or any combination thereof, of the user associated with a second gesture in the video data captured by the image capture device;
receive an authenticated gesture sequence; and
grant access to a user account based on determining that the first gesture and the second gesture correspond to the authenticated gesture sequence.
17 . The one or more tangible, non-transitory machine-readable media of claim 16 , wherein the instructions are configured to cause the one or more processors to:
identify the plurality of biomechanical points of the position of the digit, the appendage, the associated with the second gesture in subsequent portion of the video data after identifying the plurality of biomechanical points associated with the first gesture.
18 . The one or more tangible, non-transitory machine-readable media of claim 16 , wherein the instructions are configured to cause the one or more processors to:
request authentication information indicating an identity of the user; and
grant access to the user account based on determining that the first gesture and the second gesture correspond to the authenticated gesture sequence and the authentication information correlates to an authenticated user.
19 . The one or more tangible, non-transitory machine-readable media of claim 18 , wherein the instructions are configured to cause the one or more processors to prevent a subsequent attempt to access the user account based on determining that a number of unsuccessful access requests is greater than or equal to a threshold number of unsuccessful access requests.
