System and method for locating and determining substance use
View Patent ↗Levels of substance use, location, and vital signs are remotely monitored for a subject. In one embodiment, the system includes a testing device and a communication device. The testing device obtains a breathalyzer sample from a test subject and determines a substance level. The communication device reports the substance level to a remote monitoring station. In addition, location and camera functions of the communication device can report additional information for verification and system integrity. In other embodiments, the system can be incorporated into an ankle bracelet for monitoring movement of an individual or into a vehicle system to prevent operation while impaired.
1. A method for locating and determining substance use, comprising:
capturing, with a camera of a communication device, an image simultaneously containing (a) at least a portion of a face of a test subject providing a test sample to a testing device separate from the communication device, and (b) a display of the testing device displaying a unique serial number of the testing device;
sensing, within the testing device, a level of the substance within the test sample;
communicating, via an interface of the testing device, the unique serial number and the level of the substance within the test sample from the testing device to the communication device; and
sending the image, the unique serial number, the level, and a determined location of the communication device from the communication device to a remote server;
receiving, within the communication device and from the remote server, a security code generated as a pseudo random value by the remote server;
communicating the security code to the testing device; and
the captured image containing the display of the testing device further including the security code displayed on the display;
wherein the remote server validates use of the testing device by the test subject when the security code within the image matches the pseudo random value.
2. The method of claim 1 , further comprising physically coupling the communication device to the testing device to position the communication device relative to the testing device to capture the image.
3. A method for locating and determining substance use, comprising:
capturing, with a camera of a communication device, an image simultaneously containing (a) at least a portion of a face of a test subject providing a test sample to a testing device separate from the communication device, and (b) a display of the testing device displaying a unique serial number of the testing device;
sensing, within the testing device, a level of the substance within the test sample;
communicating, via an interface of the testing device, the unique serial number and the level of the substance within the test sample from the testing device to the communication device;
sending the image, the unique serial number, the level, and a determined location of the communication device from the communication device to a remote server; and
generating, within the testing device, a security code as a pseudo random value;
the captured image containing the display of the testing device further including the security code displayed on the display;
wherein the remote server validates use of the testing device by the test subject when the security code within the image matches a predicted next pseudo random value for the testing device.
