Wherein, obtaining meeting after the image in 2 D code of grey level, adopting standard algorithm to convert the Quick Response Code in effective Quick Response Code figure to character string information corresponding thereto.Wherein, standard algorithm is the one in Data Matrix, MaxiCode, Aztec, QR Code, Vericode, PDF417, Ultracode, Code49 or Code16K.
After character string after being resolved, send it to image primitive coded system, by image primitive coded system, the character string of generation is defined as to corresponding dot pattern ID.
Dot pattern ID extraction module, for placing buffer memory by the dot pattern ID corresponding with Quick Response Code obtaining after resolving.
Wherein, Quick Response Code scanning module and dot pattern scanning module are in the same plane.
By by resolve after obtain the dot pattern ID corresponding with Quick Response Code, with dot pattern by resolve after dot pattern ID contrast, whether corresponding to judge the two, if the determination result is YES, in database, search content corresponding thereto, if judged result is no, feed back abnormal information.
Wherein, in database, search simultaneously corresponding with character string dot pattern ID and the content information corresponding with the corresponding dot pattern ID of dot pattern, if lookup result is yes, by calling module, this content information is called, if lookup result is no, feed back abnormal information.
In addition, database is also provided with for the interface content information of its storage inside being upgraded and relevant setting is upgraded to database.
Calling module 7 is for calling while and two content informations that dot pattern ID is corresponding at database.In database, call simultaneously corresponding with character string dot pattern ID and the content information corresponding with the corresponding dot pattern ID of dot pattern.
Wherein, if this content information is audio file, by loudspeaker, this audio file is play.
If this content information is video file, by display screen, this video file is play.
If this content information is text, by display screen, text file is play.
In the present invention, the antifalse being formed by dot pattern and Quick Response Code identifies, by organize dot pattern and Quick Response Code forms more, organize dot pattern more and be distributed in the outside of Quick Response Code, or Quick Response Code is arranged on by organizing dot pattern more and arranges in order and form in a dot pattern frame.
The information point that dot pattern is 30～40 microns by least one group of diameter rearranges, and with the shape of specifying.Because the diameter of information point is small, and be preset with corresponding spacing distance between two adjacent information points, after the mode that is copied or scans copies, distance between adjacent two information points can be found deviation, the shape of specifying also can change, thereby form the invalid code that cannot be identified, therefore, the position of information point and the distance between the two can improve the anti-counterfeiting performance of dot pattern.In two adjacent information points, the spacing between the center of center to the second information point of being put by the first information is 80 microns.Information point in this dot pattern comprises direction reference point, center reference point and check code-point.
Dot pattern adopts the coating that can be identified by naked eyes invisible light to be attached on the white space of carrier, one in the visible coating that the coating that can be identified by naked eyes invisible light is carbon containing or the invisible coating of carbon containing, visible ink or ink that the visible coating of carbon containing is carbon containing, the colorless ink that the invisible coating of carbon containing is carbon containing or ink.Due to visible ink or the ink of carbon containing, and the colorless ink of carbon containing or ink can absorb the infrared ray of specific band, therefore, only has infrared ray recognition device to identify the information in label layer.
Only as described above, be only preferred embodiment of the present invention, such as professional who are familiar with this art.After understanding technological means of the present invention, natural energy, according to actual needs, is changed under instruction of the present invention.Therefore all equal variation and modifications of doing according to the present patent application the scope of the claims, once should still remain within the scope of the patent.
