Abstract
Disclosed herein is an illegal copy prevention system and method. In short, an anti-copy prevention system of the present invention includes, a chipless RFID disk having a print layer distributed with metal fibers; an Optical Disk Drive (ODD) reading, recorded information when mounted with the chipless RFID disk; and a reader installed in the disk drive to sense whether metal fibers distributed at the printed layer exists and a unique ID contained in the metal fiber.
Claims9
An anti-copy prevention system, comprising:
- a chipless RFID disk having a print layer distributed with metal fibers;
- an Optical Disk Drive (ODD) reading recorded information when mounted with the chipless RFID disk;
- and
- a reader installed in the ODD to sense whether the metal fibers distributed at the printed layer exist and to sense a unique ID contained in the metal fibers,
- wherein the chipless RFID disk comprises:
- a substrate having a first region and a second region;
- a reflecting layer formed on the first region of the substrate;
- and
- a protective layer formed on the reflecting layer,
- wherein a central area of the substrate has a through hole formed therethrough,
- wherein the second region is a surrounding area of the through hole,
- wherein the print layer is formed on the second region of the substrate,
- wherein a first side surface of the print layer is in direct physical contact with a first side surface of the reflecting layer and a first side surface of the protective layer,
- wherein the first side surface of the print layer comprises a first part contacted with the first side surface of the reflecting layer and a second part contacted with the first side surface of the protective layer,
- wherein a second side surface of the print layer is exposed to an outside by the through hole,
- wherein a top surface of the print layer is exposed to an outside,
- wherein a bottom surface of the print layer is in direct physical contact with a top surface of the substrate,
- wherein the first region is a recorded region and the second region is an unrecorded region, and
- wherein the first side surface of the print layer, the first side surface of the reflecting layer, and the first side surface of the protective layer are a boundary line between the first region and the second region.

An anti-copy prevention method, comprising:
- mounting a chipless RFID disk having a print layer distributed with metal fibers, on a disk drive installed with a reader;
- reading the chipless RFID disk by the reader;
- determining, as a result of reading the chipless RFID disk, whether the metal fibers in the chipless RFID disk exist;
- recognizing an ID contained in the metal fibers of the chipless RFID disk, when the metal fibers exist in the chipless RFID disk;
- determining whether the contained ID is a lawful ID;
- and
- reading the disk using the disk drive when the contained ID is lawful,
- wherein the chipless RFID disk comprises:
- a substrate having a first region and a second region;
- a reflecting layer formed on the first region of the substrate;
- and
- a protective layer formed on the reflecting layer,
- wherein a central area of the substrate has a through hole formed therethrough,
- wherein the second region is a surrounding area of the through hole,
- wherein the print layer is formed on the second region of the substrate,
- wherein a first side surface of the print layer is in direct physical contact with a first side surface of the reflecting layer and a first side surface of the protective layer,
- wherein the first side surface of the print layer comprises a first part contacted with the first side surface of the reflecting layer and a second part contacted with the first side surface of the protective layer,
- wherein a second side surface of the print layer is exposed to an outside by the through hole,
- wherein a top surface of the print layer is exposed to an outside,
- wherein a bottom surface of the print layer is in direct physical contact with a top surface of the substrate,
- wherein the first region is a recorded region and the second region is an unrecorded region, and
- wherein the first side surface of the print layer, the first side surface of the reflecting layer, and the first side surface of the protective layer are a boundary line between the first region and the second region.
