Description

QR Code Preventing Forgery and Falsification Comprising Photonic Crystal Materials and Method Using there of}

The present invention relates to a QR code for preventing forgery and alteration including a photonic crystal material and a method for manufacturing the same, and more specifically, to check whether the color changes with the QR code and the naked eye which implements an authentication procedure for forgery or alteration with a computer or a mobile device. The present invention relates to a forgery prevention QR code including a shape printed by using an ink containing a photonic crystal material and a method of manufacturing the same.

Various techniques have been introduced to prevent counterfeiting and tampering of expensive goods or products that require authenticity of contents. Conventionally, technologies using fine patterns, braille, hologram, RFID, and the like have been used to prevent counterfeiting and tampering of goods, but this conventional technology has a limitation that it is not easy for ordinary users to discriminate between forgery and tampering of goods. Has the problem that it is expensive or expensive to manufacture counterfeit and tamper resistant means.

Meanwhile, a representative example of various next generation displays may be electronic ink. Electronic ink is a display that expresses a specific color by applying an electric field to a capsule containing particles of a specific color (for example, black and white, respectively) having negative and positive charges, respectively, to reduce power consumption and to be flexible. There is an advantage to enabling the display. However, the electronic ink has a limitation in that it is difficult to express various colors because the color of the particles is fixed to a specific color, and there is a limitation that the display switching speed is not suitable for expressing a moving image.

Various methods have been proposed to fundamentally solve the problems of the conventional next generation display, and among them, a method using a color nanocomposite such as a photonic crystal has been proposed.

Photonic crystal refers to a material or crystal having a characteristic of having a color corresponding to a specific wavelength by reflecting only light of a specific wavelength of the incident light and passing the light of the remaining wavelength. Representative examples of the photonic crystal include a wing of a butterfly and a beetle. Shells; Although they do not contain a pigment, they contain a unique photonic crystal structure, and thus they can give a unique color.

According to a recent study on photonic crystals, in the case of photonic crystals artificially synthesized including a predetermined material, the photonic crystals are crystallized by various external stimuli, in contrast to conventional photonic crystals in nature, which reflect only light of a specific wavelength. 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 back to the ultraviolet or infrared region as well as the visible region can be freely adjusted.

The QR code, on the other hand, is a two-dimensional barcode in matrix format representing information in a black and white plaid pattern. QR code has been widely used in various fields due to the advantage that it can store data of a size larger than a general barcode which stores unidirectional or numeric information.

In general, the QR code may read stored data through image capturing 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 view the data in the QR code.

Looking at the patent and utility model literature for the anti-counterfeiting means using the photonic crystal material and the QR code, KR Patent Application No. 10-2016-0054563 (name of the invention: printed material for preventing the forgery containing the optically variable material and its manufacturing method) Is a forgery prevention printed material comprising an information transfer layer printed with an image for preventing forgery and alteration on the substrate, the information transfer layer is an optically variable pigment (OVP), thermosensitive ink, UV ink, fluorescent ink or hologram Disclosed is a forgery-inhibiting printed material comprising a first variable layer formed by any one or a combination thereof, and a second variable layer formed by a magnetically color turnable photonic crystal (MTX).

However, in the case of the above-described forgery and alteration prevention printed material, there is an advantage that the forgery of the printed material is difficult, but there is a disadvantage that an excessively expensive printing production cost is required.
