Description
Technical field
The true and false the present invention relates to the method for anti-counterfeit of a Quick Response Code, for judging Quick Response Code, the false proof of Quick Response Code is realized, this
Invention further relates to a kind of anti-fake two-dimension code and antiforge method for commodities.
Background technology
With market economy and the development of globalization, counterfeit and shoddy goods are becoming increasingly rampant, not only disrupted the market, more endanger
The rights and interests of evil consumer.Therefore, using commodity packaging as carrier, effective counterfeit protection measures are added to reduce forgery risk, it has also become
Enterprise is preferred.And anti-counterfeit package must is fulfilled for three basic demands, i.e., easy to identify, inexpensive and difficulty is copied.At present, Quick Response Code is made
For widely used information carrier, have the characteristics that to contain much information, easy to identify, cost is low, being applied to that packaging is upper can conveniently consumption
Person quickly obtains merchandise news, while strengthens consumer and pack interactive between itself.But Quick Response Code is easily imitated,
Itself does not possess antiforge function.Quick Response Code commodity counterfeit prevention to be used as, its imitated hardly possible must be just improved using other technological means
Degree.
Quick Response Code be distributed in the two-dimensional direction according to certain rule according to specific geometric figure it is chequered with black and white
Graphic recording data symbol information, by image input device or scanning device with identify image and then read information.Profit at present
With VDP technology（Variable Data Printing, abbreviation VDP）The variable two-dimension code label tool generated at random
There is false proof function, and have begun to commercial applications.VDP technologies refer in the case of non-stop-machine, continuously printing figure message
Content needs the printing changed, can so generate the different pattern in 2 D code of content at random, realizes " one yard of a thing ", has ensured business
The uniqueness of product, but still suffer from the drawbacks of can copying duplication.The other common solutions for realizing two-dimension code anti-counterfeit be with it is other
Method for anti-counterfeit, physical security, digital watermarking, security coating etc. is combined, and forms packaging integrated anti-counterfeit system, such as
CN103465606A and CN105303959A, CN106935131A and CN105469132A, although false proof reliability improves, together
When also increase the anti-counterfeiting cost of packaging.
The A of CN 103955658, there is provided a kind of dimension code anti-counterfeit method and system, this method comprise the following steps：From having printed
System, with being selected at random among one or more Quick Response Codes of the caused specific random character of one or more during printing
One or more Quick Response Codes are selected as sampling Quick Response Code；One or more specific random characters of extraction sampling Quick Response Code；To every
Individual specific random character carries out the random character statistical value that statistics obtains each specific random character；Storage is each specific random special
The random character statistical value of sign and the threshold value of setting；Extract one or more specific random characters of Quick Response Code to be verified；It will carry
The random character statistical value of each specific random character for the Quick Response Code to be verified got and the specific random character stored
Contrast, and by comparing result compared with threshold value；Based on comparative result, it is true code or pseudo-code to judge Quick Response Code to be verified.This side
The anti-counterfeiting technology that VDP technologies generate variable two-dimension code at random is applied in case, but this scheme is only used for the anti-of variable two-dimension code
Puppet, the false proof of static two dimensional code can not to be used for.
Therefore, the reliability of two-dimension code anti-counterfeit, applicability and anti-counterfeiting cost etc. all need to be improved in the prior art.
The content of the invention
The method for anti-counterfeit of Quick Response Code provided by the invention, false proof reliability is high, and variable two-dimension code and static two dimensional code are suitable
