Abstract

Various embodiments provide systems and methods for determining the veracity of location data gathered about a monitored individual.

First claim

What is claimed is:

1 . A method for identifying questionable tracking data, the method comprising:
receiving a first location data from a user detached monitor device, wherein the first location data includes a first location of the user detached monitor device obtained at a first time, and wherein the user detached monitor device is configured to connect to a user attached monitor device; receiving a second location data from a third-party location service, wherein the second location data includes a second location of a non-associated device to which the user attached monitor device connected, wherein the second location was obtained at a second time; determining, by a processing resource, that a difference between the first time and the second time is within a defined period of time; determining, by the processing resource, that a distance between the first location and the second location is greater than an expected distance; and indicating, by the processing resource, a questionable location from the user detached monitor device based on the distance between the first location and the second location being greater than the expected distance.

2 . The method of claim 1 , wherein the user attached monitor device is configured to connect to the user detached monitor device within a first maximum distance; wherein the user attached monitor device is configured to connect to non-associated device within a second maximum distance.

3 . The method of claim 2 , wherein the first maximum distance is the same as the second maximum distance.

4 . The method of claim 2 , wherein the first maximum distance is less than five meters and the second maximum distance is less than ten meters.

5 . The method of claim 2 , wherein the expected distance is greater than or equal to a sum of the first maximum distance and the second maximum distance.

6 . The method of claim 1 , wherein the expected distance is user programmable.

7 . The method of claim 1 , wherein the period of time is user programmable.

8 . The method of claim 1 , wherein the first location data includes a time stamp indicating when the first location was obtained and a device identification of the user attached monitor device.

9 . The method of claim 1 , wherein the second location data includes a time stamp indicating when the second location was obtained and a device identification of the user attached monitor device.

10 . The method of claim 1 , wherein the processing resource is communicably coupled to a display, and wherein indicating the questionable location from the user detached monitor device includes displaying a message indicating the questionable location on the display.

11 . The method of claim 1 , wherein the user detached monitor device is a mobile phone.

12 . A monitoring system, the system comprising:
a user attached monitor device including:
a strap configured for attachment to a monitored individual;
a wireless transceiver configured to connect to a first wireless device within a first defined range and a second wireless device within a second defined range; and
a status indicator configured to detect a status of the user attached monitor device;
the first wireless device assigned to the monitored individual and including:
a first location subsystem configured to obtain a first location of the first wireless device;
a clock configured to time stamp the first location with a first time corresponding to obtaining the first location;
a central monitoring station configured to:
receive the first time and the first location directly from the first wireless device;
receive a second location of the second wireless device and a time stamp for the second location from a third party location service with which the second wireless device is associated;
determine that a difference between the first time and the second time is within a defined period of time;
determine that a distance between the first location and the second location is greater than an expected distance; and
indicate a questionable location from the first wireless device based on the distance between the first location and the second location being greater than the expected distance.

13 . The system of claim 12 , wherein the first defined range is the same as the second defined range.

14 . The system of claim 12 , wherein the first defined range is less than five meters and the second defined range is less than ten meters.

15 . The system of claim 12 , wherein the expected distance is greater than or equal to a sum of the first defined range and the second defined range.

16 . The system of claim 12 , wherein the expected distance is user programmable.

17 . The system of claim 12 , wherein the period of time is user programmable.

18 . The system of claim 12 , wherein the first defined range is less than the second defined range, and wherein a power of the wireless transceiver is increased to connect out to the second defined range based at least in part on the status of the user attached monitor device.

19 . The system of claim 18 , wherein the status of the user attached monitor device is selected from a group consisting of: occurrence of a timeout condition; detection of tampering with the user attached monitor device, and a change in proximity between the user attached monitor device and the monitored individual.

20 . A user attached monitor device, the user attached monitor device comprising:
a strap configured for attachment to a monitored individual; a wireless transceiver configured to connect to a first wireless device within a first defined range and a second wireless device within a second defined range, wherein the first defined range is less than the second defined range; and a status indicator configured to detect a status of the user attached monitor device, wherein the status of the user attached monitor device is selected from a group consisting of: occurrence of a timeout condition; detection of tampering with the user attached monitor device, and a change in proximity between the user attached monitor device and the monitored individual; and wherein a power of the wireless transceiver is increased to connect out to the second defined range based at least in part on the status of the user attached monitor device.
