Fig. 2 is a block diagram of a bar code system.

1 to 6, the anti-falsification bar code 100 according to the first embodiment of the present invention is directly attached to the curved surface or the irregular surface (hereinafter referred to as " surface 20a " Is printed.

Here, the object 20 may be a bottle, a container case or the like made of glass or transparent plastic made of silicon dioxide (SiO 2), aluminum oxide (Al 2 O 3) or the like.

However, the material and the type of the object 20 are not limited thereto, and the object 20 may be made of metal, paper, fiber, synthetic resin, or the like.

The anti-fake bar code 100 may include a plurality of bars 110, a cord 120, and a detachable piece 130.

The plurality of bars 110 include code information corresponding to management information such as a producer country, a manufacturer, a product type, and a distribution route stored in the main server 14.

The code 120 may display the code information using letters, numbers, symbols, graphics, and the like.

The code information of the anti-falsification bar code (100) includes a scanner (11) for emitting light to the plurality of bars (110) and absorbing light reflected from the plurality of bars (110) A decoder 12 for converting the information about the intensity of the light reflected from the display unit 110 into a digital signal and an information processing unit 13 for transmitting the digital signal transmitted from the decoder 12 to the main server 14 Can be managed by one barcode system 10.

The plurality of bars 110 may be printed directly on the surface 20a of the article.

The cord 120 may also be printed directly on the surface 20a of the article adjacent to the bar.

The detachable piece 130 may be attached to the surface 20a of the object to be positioned on the upper side of the plurality of bars 110 or between the plurality of bars 110 and the surface 20a of the object .

The detachable piece 130 is not limited to the material as long as it can be detached from the surface 20a of the object by tape, thread, string, or the like.

When the detachable piece 130 is removed from the surface 20a of the object, the detachable piece 130 can remove a part of the respective bar 110 from the surface 20a of the object 20a Reference).

For example, when the removable piece 130 is removed when the object 20 is sold, a portion of each bar 110 is damaged, so that the anti-falsification bar code 100 can not be reused.

When the detachable piece 130 is removed in the longitudinal direction of the bar 110, at least one of the plurality of the bar 110 is removed, Counterfeiting of the anti-falsification bar code 100 becomes virtually impossible (see Figs. 2C, 2D, and 5B).
