Substance Testing Systems and Methods with Test Subject Identification Using Electronic Facial Recognition Techniques
First Claim
1. A method for identifying a test subject being tested for consumption of a selected substance comprising:
- storing in a database of a facial recognition processing system a gallery of facial images of a set of individuals;
receiving with the facial recognition processing system a facial image of a test subject being tested for consumption of a selected substance;
comparing the received facial image with at least some of the facial images in the stored gallery using a facial recognition algorithm executed by the facial recognition processing system;
in response to a match between a facial image in the stored gallery and the received facial image having a predetermined level of match certainty, identifying the test subject with the facial recognition processing system; and
in response to a failure to obtain a match between a facial image in the stored gallery and the received facial image having a predetermined level of match certainty, flagging the received facial image with the facial recognition processing system for subsequent manual analysis.

Abstract
A method for identifying a test subject being tested for consumption of a selected substance includes storing in a database of a facial recognition processing system a gallery of facial images of a set of individuals. The facial recognition processing system receives a facial image of a test subject being tested for consumption of the selected substance and compares the received facial image with at least some of the facial images in the stored gallery by executing a facial recognition algorithm. In response to a match between a facial image in the stored gallery and the received facial image having a predetermined level of match certainty; the facial recognition processing system identifies the test subject. In response to a failure to obtain a match between a facial image in the stored gallery and the received facial image having a predetermined level of match certainty, the facial recognition processing system flags the received facial image for subsequent manual analysis.

8. A method of controlling a vehicle sobriety interlock system comprising:
-
taking a facial image of a vehicle operator with a camera forming a portion of a vehicle sobriety interlock system; comparing the facial image of the vehicle operator with a set of facial images stored in a database with a processing system executing a facial recognition algorithm; and in response to a match of a predetermined level of certainty between the facial image of the vehicle operator and a facial image of the set of images selectively activating a test device forming a portion of the vehicle sobriety interlock system for testing the vehicle operator for consumption of a selected substance. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for controlling operation of a vehicle having a vehicle sobriety interlock system comprising:
-
a camera forming a portion of a vehicle sobriety interlock system for taking a facial image of a vehicle operator; a database storing a set of facial images; and a processing system operable to; execute a facial recognition algorithm to compare the facial image of the vehicle operator with the set of facial images stored in a database; and in response to a match of a predetermined level of certainty between the facial image of the vehicle operator and a facial image of the set of images selectively activating a test device forming a portion of the vehicle sobriety interlock system for testing the vehicle operator for consumption of a selected substance. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method of controlling a vehicle sobriety interlock system comprising:
-
storing at least one first facial image in a database; taking a second image with a camera forming a portion of a vehicle sobriety interlock system of an object; executing a facial detection algorithm with a processor using the at least one facial image and the second image to determine if the object is a human face; in response to a determination that the object is a human face, enabling the vehicle sobriety interlock system for testing the vehicle operator for consumption of a selected substance; and in response to a determination that the object is not a human face, maintaining the vehicle sobriety interlock system in a disabled state. - View Dependent Claims (22, 23, 24)

25. A method of testing for the use of a selected substance by an individual comprising:
-
during a predetermined test time window, collecting an air sample through an intake of a breath testing unit capable of measuring an amount of the selected substance in the air sample; during collecting of the air sample, taking an image of an area proximate the intake of the breath testing unit with a camera; and with a processing system; processing measurement data received from the breath testing unit to determine whether the amount of the selected substance in the air sample exceeds a predetermined threshold; processing image data received from the camera with an algorithm capable of detecting a human face from the image data received from the camera with a predetermined degree of confidence; if the amount of the selected substance in the air sample exceeds the predetermined threshold, recording the substance test as failed; if the amount of the selected substance in the air sample does not exceed the predetermined threshold and a human face is not detected in the image data received from the camera, recording the test as failed. - View Dependent Claims (26, 27, 28, 29, 30, 31)

32. A system for testing an individual for consumption of a selected substance comprising:
-
a breath testing unit for measuring an amount of the selected substance in an air sample received at an air intake; a camera for taking an image of an area proximate the air intake during the collection of the air sample; and a least one processor operable to; process measurement data generated by the breath testing unit to determine whether the amount of the selected substance in the air sample exceeds a predetermined threshold; and process image data received from the camera with a facial detection algorithm capable of detecting a human face in the received image data with a predetermined degree of confidence; wherein the individual passes a test for consumption of the selected substance when the at least one processor determines that the amount of the selected substance in the air sample is below the preselected threshold and the at least one processor detects a human face in the image data received from the camera. - View Dependent Claims (33, 34, 35)
