Abstract

A system and method of marking goods for authentication and tracking purposes is described. The system and method include a central control which enables the system. The method and system are accomplished in real time affording manufacturers the ability to eliminate problems associated with counterfeiting and diversion which begin at the manufacturing site. A central control unit enables the system by providing an allotment of marks to a host unit. The host unit directs marking terminals to mark particular goods or documents with specific information encoding symbols. Goods or documents are either marked directly, or are identified by means of affixed fixtures which are marked with encoding symbols either prior to, or subsequent to, affixing to the goods. Following marking, documents, goods or fixtures are scanned to insure proper marking and then packaged for shipment. Following marking, the documents, goods or affixed fixtures can be checked by illuminating the symbols marked thereon and cross referencing this data with the host database by using a field reading unit, or alternately decoded into clear text at the field reader for analysis.

Claims

1. A method of coding cloth to enable subsequent identification in counterfeit prevention wherein the method comprises the steps of:

a) placing an identifying pattern on a bolt of cloth prior to utilizing the cloth in making a garment;

b) encoding the pattern on the cloth using a cloth impregnating material having an air dried solvent and a single dye wherein the dye forms the encoded pattern and responds to light in one selected frequency range;

c) forming the pattern on the cloth in accordance with a pattern unique to the cloth so that cloth specific encoding is accomplished and wherein the pattern can be subsequently captured with a single scan; and

d) utilizing the cloth in fabrication of the garment.

2. The method of claim 1 including the step of forming the cloth specific pattern along the length of a bolt of cloth.

3. The method of claim 2 including the step of forming the cloth specific code of a washable dye on the back face of the cloth.

4. The method of claim 3 including the step of inspecting the cloth in the finished garment with a light source having a specified frequency range to illuminate the pattern and reading the illuminated pattern.

5. The method of claim 1 including the step of reading the pattern which determines a form of the pattern and comparing the read pattern with a list of permissible pattern forms indicative of genuine garments.

6. The method of claim 5 further including the step of making garments with lot numbers, collecting a list of lot numbers, and circulating the list of lot numbers to authorized inspectors to enable remote counterfeit inspection.

7. The method of claim 6 including the step of inspecting inner surfaces of the garment with ultraviolet light.

8. The method of claim 7 including the step of inspecting the inside of a pants leg for a garment number tracing a lot number for garment manufacture.

9. The method of claim 6 wherein the inner surface of assembled garment is marked at two places.

10. The method of claim 6 wherein the pattern is marked by the UPC code.

11. The method of claim 6 wherein the code is marked with meaningless symbols and symbols marked in a predetermined pattern.

12. The apparatus of claim 11 wherein said pattern reading device is a portable computer.

13. The apparatus of claim 12 wherein said portable computer has a memory input of at least one acceptable pattern number.

14. A method of coding cloth to enable subsequent identification in counterfeit prevention wherein the method comprises the steps of:

a) placing an identifying pattern on a bolt of cloth prior to utilizing the cloth in making a garment;

b) encoding the pattern on the cloth using a cloth impregnating material having an air dried solvent and a single dye wherein the dye forms the encoded pattern and responds to light in one selected frequency range;

c) forming the pattern on the cloth in accordance with a pattern unique to the cloth so that cloth specific encoding is accomplished and wherein the pattern can be subsequently captured with a single scan;

d) defining genuine cloth by verifying that the formed pattern has been properly applied to the cloth by comparing said formed pattern with a stored list permissible pattern forms; and

e) after said verification, utilizing the genuine cloth in fabrication of the garment.

15. The method of claim 14 including the steps of:

a) reading the pattern after fabrication of said garment; and

b ) comparing the read pattern with-the-list of permissible pattern forms to determine if the garment is fabricated from genuine cloth.

16. The method of claim 15 including the step of forming the cloth specific pattern along the length of a bolt of cloth.

17. The method of claim 16 including the step of inspecting the cloth in the finished garment with a light source having a specified frequency range to illuminate the pattern and reading the illuminated pattern.

18. The method of claim 17 including forming the cloth specific code of a washable dye on the back face of the cloth.
