Abstract
The invention relates to a merchandise anti-counterfeiting method and a merchandise anti-counterfeiting information reading device, which relates to the anti-counterfeiting technology. The merchandise anti-counterfeiting method comprises a coding step and a decoding step, and is characterized in that the coding step comprises the steps: coding product information as a dot matrix image, arranging the dot matrix image on the surface of a merchandise packaging article, wherein the edge length of an equivalent square of a single pixel forming the image is less than 0.05mm. The method has beneficial effects that the anti-counterfeiting pattern is formed by micro dot matrix which is invisible to eyes, a special anti-counterfeiting code reading device is adopted, the counterfeiting difficulty and the counterfeiting cost can be increased, and the anti-counterfeiting effect can be improved. Moreover, a coding rule adopts a private rule, and a decoding device has an encryption means which is difficult for a counterfeiter to decrypt.
Description
Technical field
The present invention relates to anti-counterfeiting technology.
Background technology
Existing printing-type commodity counterfeit prevention information mostly is and arranges security code on commodity package surface, as printed bar code, Quick Response Code etc., because bar code, Quick Response Code are less demanding to printing technology, slavish copying is not difficult, on the other hand, the reading instrument of bar code and Quick Response Code is general device, all have impact on antifalse effect.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of antiforge method for commodities and commodity counterfeit prevention information read device, has stronger antifalse effect compared with prior art.
The technical scheme that the present invention solve the technical problem employing is, antiforge method for commodities, comprise coding step and decoding step, it is characterized in that, coding step comprises: so that product information is encoded to dot matrix image, and dot matrix image is arranged at commodity package surface, the foursquare length of side of equivalence of the single pixel of composing images is less than 0.05mm.
Further, decoding step comprises: scanned as data file by CCD after dot matrix image optical amplifier again, and decodes according to coding rule, then exports.Described dot matrix image comprises the string diagram that pixel is formed, and product information is encoded to lines arrangement mode.Described dot matrix image adopts digital watermark to be printed on commodity package surface.In described string diagram, have at least the width of effective lines to be less than or equal to the twice of the single pixel length of side, the distance between lines is less than or equal to three times of the single pixel length of side.
The present invention also provides a kind of commodity counterfeit prevention information read device, it is characterized in that, comprise optical amplifier unit, CCD, processor unit, storage unit and output unit, optical amplifier unit is arranged at the light path front of CCD, CCD is connected with processor unit, processor is connected with storer, and processor is also connected with output unit, and described cell stores has product information to encode.
Described output unit comprises voice output module.Described storage unit comprises portable memory storage, such as SD card.
The invention has the beneficial effects as follows, the present invention adopts naked eyes visible small dot matrix formation security pattern hardly, and adopts special security code reading device, adds difficulty and the cost of false making, improves antifalse effect.Particularly, coding rule of the present invention adopts privately owned rule, and decoding device has encryption measures, and counterfeiter is difficult to crack.

Embodiment
See Fig. 1.
Antiforge method for commodities, comprise coding step and decoding step, it is characterized in that, coding step comprises: so that product information is encoded to dot matrix image, and dot matrix image is arranged at commodity package surface, the foursquare length of side of equivalence of the single pixel of composing images is less than 0.003mm.
Pixel cell of the present invention refers to the elementary cell forming pattern, and for the Quick Response Code shown in Fig. 3, namely the black squares in the circle of arrow indication is a pixel cell.For other dot matrix string diagram, namely effective line thickness (width that namely can be identified) minimum value is the width of a pixel cell.Because its size is less, actual pixel likely can not form the square of standard, then using its equivalent foursquare size as criterion, equivalent square of the present invention refers to the maximum square that a geometric figure can hold, as shown in Figure 2, the part beyond geometric border is not included in equivalent square interior.
Described dot matrix image comprises the string diagram that pixel is formed, and product information is encoded to lines arrangement mode.
In string diagram, have at least the width of effective lines to be less than or equal to the twice of the single pixel length of side, the distance between lines is less than or equal to three times of the single pixel length of side.Described effective lines refer to the lines as information carrier, can be read device identification.
The dot matrix image of present embodiment adopts digital watermark to be printed on commodity package surface, can need identify during reading by ultraviolet.
Encoding of graphs of the present invention adopts self-defining coding rule, and the simplest example directly adopts one-dimension code or Quick Response Code, and it is miniature, and prints with digital watermark.
Decoding step comprises: scanned as data file by CCD device after dot matrix image optical amplifier again, and decodes according to coding rule, then exports in the mode of voice broadcast, or outputs to outer computer with data transfer mode.
