Abstract

A counterfeit detection method includes electronically reading a label on a desired item in a store, transmitting an item identification code encoded in the read label to an authentication unit, receiving an indication from the authentication unit whether or not the item identification code is registered to the store and if the indication is positive, generating a certificate of authenticity for the desired item.

Claims

1. A counterfeit detection method comprising:

reading a label attached to a manufactured item, said label incorporating a manufacturer-controlled identification number;

with said identification number, querying a third party authority to verify that a retailer of said item received title to said item from a chain of non-consumer owners beginning with its indicated manufacturer; and

indicating that said item is not counterfeit if said retailer received title to said item from said chain.

2. The method according to claim 1 and wherein said reading comprises scanning said label with a bar code reader.

3. The method according to claim 1 wherein said identification number is encoded in said label and wherein said encoded number is one of the following code types:

one-dimensional bar code, two-dimensional bar code, RFID tag and a magnetic tag.

4. A method according to claim 1 and wherein a database maintained by said third party authority stores identities of commercial entities to whom said items are sold from manufacture until point of sale.

5. A point of sale unit in a store, the unit comprising:

a reader to read a label attached to a manufactured item, said label incorporating a manufacturer-controlled identification number;

a verifier to query a third party authority with said identification number to verify that said store received title to said item from a chain of non-consumer owners beginning with its indicated manufacturer; and

a printer to indicate that said item is not counterfeit if said retailer received title to said item from said chain.

6. The unit according to claim 5 and wherein said reader comprises one of the following readers:

a one-dimensional bar code reader, a two-dimensional bar code reader, an RFID tag reader, and a magnetic tag reader.

7. A counterfeit detection method comprising:

maintaining a database for cataloguing;

manufactured items identified by manufacturer-controlled identification numbers; and

commercial entities to which said items are sold from manufacture until point of sale;

receiving a query from a store regarding a particular one of said identification numbers wherein said particular identification number is associated with a particular one of said items; and

indicating that said item is not counterfeit if said store is recorded in said database as owning said particular item.
