Example Embodiment

[0020] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0021] See figure 1 , figure 1 It is a schematic flow chart of an embodiment of the method for authenticating the visual graphic symbol encoding according to the present invention, such as figure 1 As shown, including the following steps:

[0022] S11: Obtain a password used to verify the authenticity of the visual graphic symbol code, where the password is a password corresponding to the visual graphic symbol code used to identify the object.

[0023] When the user of the article needs to verify the authenticity of the visual graphic symbol code on the object, the query can be made through a password. Specifically, the client for query obtains a password for verifying the authenticity of the visual graphic symbol encoding. Among them, the way to obtain the password is to input or scan a QR code by the user. The user input method is specifically that the password is set...

Abstract

The invention discloses a visual graphic symbol code authenticity checking method. The method comprises the following steps: obtaining passwords for checking visual graphic symbol code authenticity, wherein the passwords are passwords corresponding to a visual graphic symbol code for identifying an object; sending the passwords to a server; and receiving the visual graphic symbol code fed back by the server according to the passwords to check the authenticity of the visual graphic symbol code for identifying the object, wherein the visual graphic symbol code for identifying the object locates on the object, the generation process of the visual graphic symbol code is characterized by enabling relevant information of the object to be generated into the passwords and enabling the passwords to be generated into the PDF visual graphic symbol code, and the visual graphic symbol code is formed by graphic elements. The invention also discloses a visual graphic symbol code authenticity checking device. Through the mode above, the authenticity can be identified visually, and an anti-counterfeit effect can be improved.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a method and device for authenticity checking of visual graphic symbol coding. Background technique [0002] Visual graphic symbol coding is mainly used for the coding of items, such as one-dimensional codes, two-dimensional codes, etc. Barcodes are a plurality of black bars and blanks of different widths arranged according to certain coding rules to express a set of graphical symbols for information symbol. Bar codes can identify information such as the country of manufacture, manufacturer, commodity name, and production date of the item, so they are widely used in many fields. [0003] Since the barcode needs to meet a wide range of scanning and identification, its coding program and application tool software are not controlled, and the entire system is transparent and has no anti-counterfeiting function. How to make the visual graphic symbol coding have anti-cou...
