RFID Tag Preventing Forgery and Falsification Comprising Photonic Crystal Materials and Method Using there of}

The present invention relates to an electronic tag for preventing forgery and alteration, including a photonic crystal material, and more specifically, a photonic crystal material capable of confirming whether the color is changed visually with an electronic tag and a naked eye for which an authentication procedure for falsification is implemented by a computer. It relates to an electronic tag for preventing forgery and alteration including a shape printed using an ink containing a.

Conventionally, a one-dimensional code reader or reader such as a barcode has been used for optical code reading. Barcodes are used to indicate the type of product that complies with the World Product Code (UPC) or to manage sales information (POS: point of sales) in supermarkets.

Recently, a two-dimensional code reader represented by a QR (quick response) code that uses a plaid on a flat surface has been used to contain more information than a one-dimensional code. QR code is a two-dimensional barcode in matrix format that displays information in a black and white plaid pattern. QR code is widely used in various fields due to the advantage of being able to store data of a larger size than a general barcode that stores numeric or character information in one direction.

In general, QR codes can read stored data through image capture through a camera or a device equipped with a separate reader. That is, anyone who has the means to read the standard QR code can access the data in the QR code.

However, in the case of QR code, the problem of sensitive lighting and focal length occurs during the code recognition process, and recently, NFC has been increasingly used as an area of RFID technology. NFC is a technology that can exchange data between terminals at short distances (approximately within 10 cm) using a 13.56 Mhz frequency band and is non-contact, but is often used as a payment method, but it can exchange information such as travel information, traffic information, and personal information. It is becoming a means to be able to.

On the other hand, various techniques have been introduced to prevent counterfeit and tampering of expensive products or products requiring authenticity of contents. Conventionally, techniques using fine patterns, braille, hologram, RFID, etc. have been mainly used to prevent counterfeiting and tampering of products, but these prior arts have limitations that it is not easy for ordinary users to discriminate whether products are counterfeit or tampering. It has the problem of having a high cost in manufacturing counterfeit or tamper-evident means.

Various methods have been proposed to fundamentally solve the aforementioned problems of the forgery and tamper- evident means, and among them, a method using a color nanocomposite such as a photonic crystal has been proposed.

Photonic crystal refers to a substance or crystal having a property that has a color corresponding to a specific wavelength by reflecting only light of a specific wavelength among incident light and passing through light of the other wavelength. Representative examples of the photonic crystal include butterfly wings and beetles. And back skin. Although they do not contain a pigment, they can have a characteristic color because they contain a unique photonic crystal structure.

According to a recent study on photonic crystals, in the case of an existing photonic crystal existing in nature, only a specific wavelength of light is reflected, whereas in the case of an artificially synthesized photonic crystal containing a predetermined material, crystals of the photonic crystal by various external stimuli It has been found that the structure (for example, the interlayer thickness constituting the photonic crystal) can be arbitrarily changed, and as a result, the wavelength of light reflected not only in the visible region but also in the ultraviolet or infrared region can be freely adjusted.

Looking at the patent and utility model literature on the forgery prevention method using RFID, the EPC standard in KR Patent Application No. 10-2010-0030842 (invention name: RID tag for copy protection, copy protection system and method using the same) An RFID tag including a plurality of memory banks for storing predetermined information therein, comprising: a first memory bank in which information input by a user is stored; A second memory bank in which tag ID information for the corresponding tag is stored; A third memory bank in which electronic product code (EPC) information for an object to which the tag is attached is stored in association with the tag ID information; And an access password area in which an access memory for controlling access to the tag is stored, and accessible through the access password, and assigned in association with the EPC information of the object, thereby determining the uniqueness of the RFID tag. Disclosed is an RFID tag for copy protection that includes a fourth memory bank having a kill password area in which secret information is stored.

However, in the case of the RFID tag for preventing the above-described copying, it is possible to determine whether or not the forgery is falsified only through the RFID reader, and there is a problem that cannot be confirmed through the naked eye.
