Abstract

A system includes a memory for storing a predetermined path through a plurality of data reading points in a auto-ID system, a plurality of auto-ID tracking devices operable to track an asset at the data reading points, and a processor. The processor is operable to receive data provided from the tracking devices about progress of the asset through the auto-ID system and operable to determine, based on received data indicating that the asset has passed through fewer than all of the plurality of data reading points in the predetermined path, whether or not the progress of asset through the auto-ID system has followed the predetermined path.

Claims

1. A system comprising:

a memory for storing a predetermined path through a plurality of data reading points in an auto-ID system;

a plurality of auto-ID tracking devices operable to track an asset at the data reading points; and

a processor operable to receive data provided from the tracking devices about progress of the asset through the auto-ID system and operable to determine, based on received data indicating that the asset has passed through fewer than all of the plurality of data reading points in the predetermined path, whether or not the progress of asset through the auto-ID system has followed the predetermined path.

2. The system of claim 1, wherein the asset is a physical object.

3. The system of claim 1, wherein the asset is associated with an identifier that is identified by the tracking devices.

4. The system of claim 1, wherein the identifier is an RFID tag.

5. The system of claim 1, at least one tracking device is operable to track a time at which the asset is identified with a data reading point within the auto-ID system.

6. The system of claim 1, further comprising an auto-identification device in communication with at least one tracking device, and operable to receive data provided from the tracking devices about progress of the asset through the auto-ID system.

7. The system of claim 1, further comprising a user interface operable to receive an identifier of the asset.

8. The system of claim 1, further comprising an object status database operable to provide a current status or location of the asset with respect to the data reading points.

9. The system of claim 1, further comprising:

a user interface operable to receive an identifier of the asset; and

an object status database operable to provide a current status or location of the asset with respect to the data reading points.

10. A method comprising:

defining a path through an auto-ID system at a plurality of data reading points in the auto-ID system;

receiving tracking data from tracking devices associated with fewer than all of the plurality of data reading points indicating that an asset has been associated with the fewer than all of the plurality of data reading points; and

determining, based on the received data, whether or not progress of the asset through the auto-ID system has followed the predetermined path.

11. The method of claim 10, wherein the asset is a physical object.

12. The method of claim 10, further comprising associating the asset with an identifier that is identified by the tracking devices.

13. The method of claim 12, wherein in the identifier is an RFID tag.

14. The method of claim 10, further comprising:

receiving timing data about a time at which the asset is identified with a data reading point within the asset movement; and

determining, based on the received tracking and timing data, whether or not progress of the asset through the auto-ID system has followed the predetermined path.

15. The method of claim 10, further comprising:

receiving status data from one or more tracking devices associated with a data reading point; and

determining, based on the received tracking and status data, whether or not progress of the asset through the auto-ID system has followed the predetermined path.

16. The method of claim 10, further comprising:

monitoring passages of a plurality of assets following the predetermined path though the auto-ID system with a plurality of tracking devices;

generating statistical data about the passage of an asset through the auto-ID system from data about the monitored passages; and

determining, based on the statistical data and the received tracking data, whether or not progress of the asset through the auto-ID system has followed the predetermined path.

17. The method of claim 10, further comprising:

receiving timing data about a time at which the asset is identified with a data reading point within the auto-ID system;

receiving status data from one or more tracking devices associated with a data reading point;

monitoring passages of a plurality of assets following the predetermined path though the auto-ID system with a plurality of tracking devices;

generating statistical data about the passage of an asset through the auto-ID system from data about the monitored passages; and

determining, based on the timing data, the status data, the statistical data and the received tracking data, whether or not progress of the asset through the auto-ID system has followed the predetermined path.

18. The method of claim 10, further comprising detecting the presence of counterfeit goods in the auto-ID system based on a determination that progress of the asset through the auto-ID system has not followed the predetermined path.

19. The method of claim 10, further comprising sending an alert in response to a determination that progress of the asset through the auto-ID system has not followed the predetermined path.

20. A method of detecting non-counterfeit goods, the method comprising:

defining a path through a auto-ID system at a plurality of data reading points in the auto-ID system;

receiving tracking data from tracking devices associated with fewer than all of the plurality of data reading points indicating that goods have been associated with the fewer than all of the plurality of data reading points; and

determining, based on the received data, that the goods have followed the predetermined path through the auto-ID system and are not counterfeit goods.
