Abstract

A gaming terminal includes an input device, an image sensor, and logic circuitry. The logic circuitry detects user input received at the input device and that is associated with a restricted action, receives, via the image sensor, image data that corresponds to the user input, applies at least one neural network model to the image data to classify pixels of the image data as representing human characteristics including at least one face and at least one pose model, compares, based at least partially on pixel coordinates of (i) the human characteristics within the received image data and (ii) a user input zone within the image data, each of the pose models to the user input zone and the faces, and permits, in response to one of the pose models matching (i) a face of the at least one face and (ii) the user input zone, the restricted action.

First claim

The invention claimed is:

1. A gaming terminal comprising:
an input device configured to receive physical user input from a user;
an image sensor configured to capture image data of a user area associated with the gaming terminal, the input device being at a predetermined location relative to the user area; and
logic circuitry communicatively coupled to the input device and the image sensor, the logic circuitry configured to:
detect user input received at the input device, the detected user input associated with a restricted action;
receive, via the image sensor, input image data of the captured image data, the input image data corresponding to the detected user input;
apply at least one neural network model to the input image data to classify pixels of the input image data as representing human characteristics, the human characteristics including at least one face and at least one pose model;
based at least partially on (i) pixel coordinates of the human characteristics within the input image data and (ii) pixel coordinates of a user input zone within the input image data and associated with the detected user input, compare each of the at least one pose model to the user input zone and the at least one face; and
in response to the comparison indicating suspicious behavior, prevent the restricted action.

2. The gaming terminal of claim 1 , wherein the gaming terminal includes a three-dimensional camera including the image sensor.

3. The gaming terminal of claim 2 , wherein each of the human characteristics has an associated depth detected by the three-dimensional camera, the logic circuitry configured to remove the human characteristics having the associated depth exceeding a depth threshold.

4. The gaming terminal of claim 1 , wherein, in response to preventing the restricted action, the logic circuitry is configured to present the user with an authentication challenge, and wherein, in response to the user successfully responding to the authentication challenge as an authorized user, the logic circuitry is further configured to permit the restricted action.

5. The gaming terminal of claim 1 , wherein the suspicious behavior is indicated by at least one of: (i) the comparison failing to match the user input zone to any face of the at least one face or any pose model of the at least one pose model, (ii) an absence of any face or pose model, or (iii) detecting a printed image or display device presenting one or more of the human characteristics.

6. The gaming terminal of claim 1 , wherein the input device is a touchscreen, the detected user input associated with touch coordinates indicating a location on the touchscreen of the detected user input, wherein the logic circuitry is configured to calculate the pixel coordinates of the input zone at least partially as a function of the touch coordinates.

7. The gaming terminal of claim 1 , wherein the logic circuitry transmits an alert to an attendant device associated with the gaming terminal in response to the indication of suspicious behavior.

8. The gaming terminal of claim 7 , wherein the alert is transmitted to the attendant device further in response to the user failing an authentication challenge.

9. A method for authentication a user at a gaming terminal of a gaming system, the gaming system including at least one image sensor and logic circuitry in communication with the gaining terminal and the at least one image sensor, the method comprising:
receiving, by an input device of the gaming terminal, physical user input from the user, the physical user input associated with a restricted action;
receiving, by the logic circuitry via the at least one image sensor, input image data that corresponds to the physical user input;
applying, by the logic circuitry, at least one neural network model to the input image data to classify pixels of the received image data as representing human characteristics, the human characteristics including at least one face and at least one pose model;
based at least partially on (i) pixel coordinates of the human characteristics within the input image data and (ii) pixel coordinates of a user input zone within the input image data and associated with the physical user input, comparing, by the logic circuitry, each of the at least one pose model to the user input zone and the at least one face; and
in response to the comparison indicating suspicious behavior, preventing, by the logic circuitry, the restricted action.

10. The method of claim 9 , wherein the at least one image sensor includes a three-dimensional camera, and wherein each of the human characteristics has an associated depth detected by the three-dimensional camera, the method further comprising removing, by the logic circuitry, the human characteristics having the associated depth exceeding a depth threshold.

11. The method of claim 9 further comprising, wherein, in response to preventing the restricted action, presenting, by the logic circuitry, the user with an authentication challenge, and, in response to the user successfully responding to the authentication challenge as an authorized user, permitting, by the logic circuitry, the restricted action.

12. The method of claim 9 , wherein the suspicious behavior is indicated by at least one of: (i) the comparison failing to match the user input zone to any face of the at least one face or any pose model of the at least one pose model, (ii) an absence of any face or pose model, or (iii) detecting a printed image or display device presenting one or more of the human characteristics.

13. The method of claim 9 , wherein the input device is a touchscreen, the physical user input associated with touch coordinates indicating a location on the touchscreen of the physical user input, and wherein the method further comprises calculating, by the logic circuitry, the pixel coordinates of the input zone at least partially as a function of the touch coordinates.

14. The method of claim 9 further comprising transmitting, by the logic circuitry, an alert to an attendant device associated with the gaming terminal in response to the indication of suspicious behavior.

15. A gaming system comprising:
a gaming terminal comprising an input device configured to receive physical user input from a user;
an image sensor configured to capture image data of a user area associated with the gaming terminal, the input device being at a predetermined location relative to the user area; and
logic circuitry communicatively coupled to the input device and the image sensor, the logic circuitry configured to:
