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 goods to a host unit. The host unit directs printing terminals to mark particular goods with specific information encoding symbols. Following marking, goods are scanned to insure proper marking and then packaged for shipment. Following marking, the goods can be checked by illuminating the symbols printed thereon and cross referencing this data with the host database by using a field reading unit.

Claims

1. A method of controlling the authentication and tracking of goods and locating counterfeit goods, the method comprising the steps of:

a) providing a control central processing unit to control and enable a host central processing unit by providing an allotment of prints to label an allotted number of goods to the host central processing unit;

b) enabling the host central processing unit to direct a printer central processing unit to print encoded symbols onto a line of goods;

c) scanning goods with at least one field reader to capture symbols imprinted thereon;

d) transferring the captured symbols to the host central processing unit;

e) comparing within the host central processing unit the captured symbols with a data base of encoded symbols; and

f) transmitting to the at least one field reader an indication of the result of the comparison.

2. The method of claim 1 wherein the step of comparing the captured symbols with a data base of encoded symbols further comprises storing the scanned symbols in a field central processing unit, transmitting the scanned symbols to the host central processing unit for comparison of the scanned symbols with the data base of encoded symbols entered at the host central processing unit, and transmitting from the host central processing unit to the field central processing unit an indication of the authentication of the scanned goods.

3. The method of claim 2 wherein the step of scanning goods comprises illuminating the goods with a light source having a specified frequency range to illuminate an encoded and imprinted symbol.

4. A system for marking and inspecting goods for use in counterfeit inspection, the system comprising:

a) a controlling device for enabling the system;

b) a host device in communication with the controlling device for directing marking of goods and providing a data base of encoded symbols;

c) a marking device directed by the host device, the marking device comprising

1) a material handling mechanism to present one face of a planar material for marking; and

2) a printer directing a print onto the face of the planar material;

3) a mechanism for moving the material relative to the printer to form a repeating identification pattern along the material; and

d) a pattern reading device at a location remote from the host device wherein said pattern reading device is in communication with the host device, the pattern reading device comprising

1) a lamp for illuminating the pattern on the material;

2) a pattern scanning device for reading the illuminated pattern; and

3) a pattern recognizing computer connected to the pattern reading device to enable capture and transmission of the illuminated patterns to the host device for comparison with a data base of printed patterns to obtain an indication of an acceptable pattern wherein a notice of the result of the comparison is transmitted to the location of the pattern reading device.

5. The apparatus of claim 4 wherein said pattern reading device is a portable computer.

6. The apparatus of claim 5 wherein said computer has a memory input of acceptable pattern numbers.

7. A system for marking and tracking the distribution of goods, comprising:

an enabling control central processing unit;

a host central processing unit in communication with the control central processing unit;

a printer central processing unit in communication with the host central processing unit;

a field reader central processing unit remote from the host central processing unit and which is in communication with the host central processing unit; and

a field reader in communication with the field reader central processing unit;

wherein said control central processing unit communicates with said host central processing unit through a coded communication to enable said host central processing unit to coordinate marking of goods by providing said host with an allotment of serialized prints;

and wherein said host central processing unit communicates with said printer central processing unit through a coded communication to enable said printer central processing unit to print an encoded symbol onto the goods; and

wherein the reader central processing unit communicates with said host central processing unit to compare scanned patterns with a set of patterns entered into a data base on the host central processing unit.

8. The system of claim 7 wherein said host central processing unit is programmed to encode a set of data into a symbol which is then decoded, transmitted to the printer central processing unit, encoded at the printer central processing unit, and printed onto the goods.

9. The system of claim 7 further comprising verification means, and said verification means scans the markings applied to the goods and cross references the scanned marks with the intended mark encoded at and stored in the printer central processing unit.

10. The system of claim 7 wherein said field reader central processing unit enhances said scanned patterns prior to said communication with said central processing unit.

11. The system of claim 10 wherein the field reader scans goods observed in the field and the field reader central processing unit transmits the scanned data to the host central processing unit for verification, said host central processing unit compares the scanned mark with the marks encoded and stored in its database and said host central processing unit transmits a signal to said field central processing unit indicative of results of said comparison.

12. A system for controlling and enabling a marking and tracking system, comprising:

a control central processing unit, said CPU being in electronic communication with a host central processing unit, and said host CPU being in communication with a printer central processing unit; and

wherein said control CPU provides an allotment of encoded and serialized prints to said host CPU and whereby said host CPU is enabled to direct a printer CPU to mark a plurality of items wherein each item is printed with a unique identifying symbol.

13. A method of controlling and enabling an authenticating and anti-counterfeiting system, comprising the steps of:

providing a control CPU;

providing a host CPU wherein said control CPU communicates with said host CPU and said control CPU provides an allotment of prints to the host CPU to be used by the host CPU in directing a printer CPU to mark an allotment of goods.

14. The method of claim 13 further comprising the steps of encoding a data set into a symbol at said host CPU, downloading the data set to said printer CPU, and printing the encoded symbol representing the data set onto an allotment of goods.

15. The method of claim 14 further comprising the step of verifying the printed symbol by passing the marked goods under a camera, capturing the printed symbols, comparing the printed symbols with a data set stored in the printer CPU.

16. A method of tracking an allotment of goods, comprising:

providing a host CPU with an allotment of prints for uniquely marking the allotment of goods from a control CPU;

providing a printer CPU with an allotment of prints for marking the allotment of goods from the host CPU;

transmitting an encoded symbol from said host CPU to said printer CPU;

directing said printer CPU to imprint said encoded symbol on the allotment of goods;

scanning said imprinted symbols and verifying valid marking;

scanning the allotment of goods for the imprinted symbol with a field reading unit thereby generating scanned symbolic data;

verifying scanned marks against a data base of encoded symbols in said host CPU by transmitting the scanned symbolic data from the field reading unit to the host CPU; and

comparing said scanned symbolic data and the encoded symbols.

17. The method of claim 16 further comprising securing the communication between the control CPU and the host CPU and between the host CPU and the printer CPU.
