Abstract

A method of identifying an object having coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data. The random pattern defines a fingerprint for the object. The method includes the steps of: receiving, in a computer system, fingerprint data from a data reader interacting with the surface, the fingerprint data identifying some of the random pattern and a fiducial; using the fiducial to identify a portion of the random pattern; and identifying, using the identified portion of the random pattern, an object identity.

Claims

1. A method of identifying an object, said object comprising coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data, said random pattern defining at least one fingerprint for the object, wherein said method comprises the steps of:

receiving, in a computer system, fingerprint data from a data reader interacting with the surface, said fingerprint data identifying at least some of the random pattern and at least one fiducial;

using the at least one fiducial to identify a portion of the random pattern; and

identifying in the computer system, using the identified portion of the random pattern, an object identity.

2. The method of claim 1, wherein the object identity identifies a unique serial number.

3. The method of claim 1, wherein the object identity identifies an Electronic Product Code (EPC).

4. The object of claim 1, wherein the coded data further identifies a layout of at least one interactive element associated with the surface.

5. The method of claim 4, wherein the layout is identified by a layout number, and one layout number is associated with a plurality of objects.

6. The method of claim 1, wherein the object is a consumer product item and the coded data further identifies a product class.

7. The method of claim 6, wherein the product class is identified by a Universal Product Code (UPC).

8. The method of claim 1, wherein the coded data further identifies the object identity.

9. The method of claim 1, wherein the object identity is identified by comparing the identified portion of the random pattern with a reference fingerprint, said reference fingerprint being indexed with the object identity.

10. A method of interacting with an object, said object comprising coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data, said random pattern defining at least one fingerprint for the object, wherein said method comprises the steps of:

sensing at least some of the coded data;

sensing at least some of the random pattern;

generating fingerprint data using the sensed coded data and the sensed random pattern, said fingerprint data identifying at least some of the random pattern and at least one fiducial; and

communicating the fingerprint data to a computer system.

11. A method of recording at least one reference fingerprint for an object, said object having a unique object identity and comprising coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data, said method comprising the steps of:

sensing and recording the coded data and the random pattern;

determining at least one reference fingerprint for the object, the or each reference fingerprint comprising at least a portion of the recorded random pattern and at least one fiducial corresponding to said portion;

associating the object identity with the or each reference fingerprint.
