Personal monitor and tracking system

A method for tracking a worker in possession of a worker cellular telephone that includes a global positioning system module and for presenting tracking information about the worker to a supervisor employing a supervisor communication device, in which the worker cellular telephone and the supervisor communication device are in communication with a central monitoring server that employs a tangible memory storage device, comprising the steps of:

• (a) storing a voiceprint from the worker on the tangible memory storage device at the central monitoring server;
• (b) generating a set of predetermined location criteria for the worker and storing the predetermined location criteria on the tangible memory storage device at the central monitoring server;
• (c) receiving, at the central monitoring server, worker location data from the worker cellular telephone, the worker location data including an indication of a location of the worker cellular telephone and storing the worker location data on the tangible memory storage device;
• (d) receiving, at the central monitoring server, worker voice sample data from the worker cellular telephone;
• (e) retrieving the voiceprint from the tangible memory storage device and comparing the voice sample to the voiceprint and generating a voiceprint alert when the voice sample fails to match the voiceprint;
• (f) employing the worker location data to determine a worker location;
• (g) retrieving the predetermined location criteria from the tangible memory storage device and comparing the worker location to the set of predetermined location criteria for the worker and generating a location violation alert when the worker location is inconsistent with the predetermined location criteria;
• and
• (h) transmitting at least one of the voiceprint alert and the location violation alert from the central monitoring server to the supervisor communication device.

A personal monitoring system for monitoring a client in possession of a cellular telephone having a GPS capability in communication with a cellular telephone network, the cellular telephone including a tangible cellphone memory, the personal monitoring system comprising:

• (a) a central monitoring server in communication with the cellular telephone network, the central monitoring server including a nonvolatile memory and configured to:
• (i) store a voiceprint of the client on the nonvolatile memory;
• (ii) store a set of predetermined location criteria for the client on the nonvolatile memory;
• (iii) periodically transmit a query to the cellular telephone to request GPS location data and a voice sample from the client;
• (iv) receive, in response to the query, location data indicative of a current location of the cellular telephone and the voice sample;
• (v) compare the location data to the predetermined location criteria to determine if the location data is consistent with the predetermined location criteria;
• (vi) compare the voice sample to the voiceprint to determine if the voice sample is consistent with the voiceprint;
• and
• (vii) generate an alert if the location data is not consistent with the predetermined location criteria or if the voice sample is not consistent with the voiceprint;
• and
• (b) an application downloaded from the central monitoring server and stored on the cellphone memory of the cellular telephone, the application configured to cause the cellular telephone to:
• (i) notify the client of the query;
• (ii) record the voice sample from the client;
• (iii) detect a current location of the cellular telephone and generate location data indicative thereof;
• and
• (iv) transmit the voice sample and the location data to the central monitoring server in response to the query.
