Method and apparatus for enhanced privacy while tracking mobile workers

1. A method for tracking the location of a mobile worker, comprising:

determining that a worker with a wireless communication device having a location detecting component is assigned to be working on a work task by determining whether an acknowledgement of the work task has been received from the worker, wherein said determining that the worker is assigned to be working on the work task comprises:

assigning the work task to the worker;

receiving the acknowledgement of the work task from the worker; and

marking the worker and the wireless communication device as working on the work task;

receiving the location of the wireless communication device when the worker is assigned to be working on the work task at a first frequency;

receiving an indication from the worker via the wireless communication device that the worker is not working on the work task;

receiving a location of the wireless communication device at a second frequency that is longer than the first frequency in response to receiving the indication that the worker is not working on the work task;

receiving the location of the wireless communication device at a third frequency that is longer than the first frequency when the worker indicates that the worker is on the work task but is not actively working on the task;

generating a notification when the location of the wireless communication device is outside of an expected location of the wireless communication device when the worker is assigned to be working on the work task; and

discontinuing receiving the location of the wireless communication device upon completion of the work task.

2. The method for tracking the location of a mobile worker, as claimed in claim 1 , further comprising:

discontinuing a tracking of the location of the wireless communication device in response to receiving the indication.

3. The method for tracking the location of a mobile worker, as claimed in claim 1 , wherein the receiving the indication from the worker via the wireless communication device further comprises:

marking the worker and the wireless communication device as not working on the work task.

4. The method for tracking the location of a mobile worker, as claimed in claim 1 , wherein receiving the location of the wireless communication device comprises:

sending a location request to the wireless communication device;

receiving a reply from the wireless communication device containing current location information; and

repeating the receiving.

5. The method of claim 1 , wherein when the worker indicates that the worker is on the work task but is not actively working on the task further comprises:

receiving an acknowledgement from the wireless device that the worker is off task.

6. The method of claim 5 , wherein off task comprises a scheduled break.

7. A non-transitory tangible computer readable medium encoded with a computer program for causing a programmable device to perform:

determining that a worker is assigned to be working on a work task by determining whether an acknowledgement of the work task has been received from the worker, wherein said determining that the worker is assigned to be working on the work task comprises:

assigning the work task to the worker;

receiving the acknowledgement of the work task from the worker; and

marking the worker and the wireless communication device as working on the work task;

receiving location information related to the worker when the worker is assigned to be working on the work task at a first frequency;

receiving an indication from the worker that the worker is not working on the work task;

receiving the location information at a second frequency that is longer than the first frequency in response to receiving the indication;

receiving the location information at a third frequency that is longer than the first frequency when the worker indicates that the worker is on the work task but is not actively working on the task;

generating a notification when the location of the wireless communication device is outside of an expected location of the wireless communication device when the worker is assigned to be working on the work task; and

discontinuing receiving the location information upon completion of the work task.

8. The computer readable medium of claim 7 , wherein the determining comprises:

determining that the work task is assigned to the worker.

9. The computer readable medium of claim 7 , wherein the indication indicates that the worker has completed the work task.

10. At least one processor configured to track the location of a mobile worker, comprising:

a first module for determining that a worker with a wireless communication device having a location detection component is assigned to be working on a work task by determining whether an acknowledgement of the work task has been received from the worker, wherein said determining that the worker is assigned to be working on a work task comprises:

assigning the work task to the worker;

receiving the acknowledgement of the work task from the worker; and

marking the worker and the wireless communication device as working on the work task;

a second module for receiving a location of the wireless communication device when the worker is assigned to be working on the work task at a first frequency;

a third module for receiving an indication from the worker via the wireless communication device that the worker is not working on the work task;

a fourth module for receiving the location of the wireless communication device at a second frequency that is longer than the first frequency in response to receiving the indication that the worker is not working on the work task;

a fifth module for receiving the location of the wireless communication device at a third frequency that is longer than the first frequency when the worker indicates that the worker is on the work task but is not actively working on the task;

a sixth module for generating a notification when the location of the wireless communication device is outside of an expected location of the wireless communication device when the worker is assigned to be working on the work task; and

a seventh module for discontinuing receiving the location of the wireless communication device upon completion of the work task.

11. An apparatus, comprising:

means for determining that a worker with a wireless communication device having a location detection component is assigned to be working on a work task by determining whether an acknowledgement of the work task has been received from the worker, wherein said determining that the worker is assigned to be working on a work task comprises:

assigning the work task to the worker;

receiving the acknowledgement of the work task from the worker; and

marking the worker and the wireless communication device as working on the work task;

means for receiving a location of the wireless communication device when the worker is assigned to be working on the work task at a first frequency;

means for receiving an indication from the worker via the wireless communication device that the worker is not working on the work task;

means for receiving the location of the wireless communication device at a second frequency that is longer than the first frequency in response to receiving the indication that the working is not working on the work task;

means for receiving the location of the wireless communication device at a third frequency that is longer than the first frequency when the worker indicates that the worker is on the work task but is not actively working on the task;

means for generating a notification when the location of the wireless communication device is outside of an expected location of the wireless communication device when the worker is assigned to be working on the work task; and

means for discontinuing receiving the location of the wireless communication device upon completion of the work task.
