Description
Technical field
The present invention relates to anti-counterfeiting technologies, and in particular to it is a kind of can by commodity packaging, include the anti-fake of commodity counterfeit prevention information
Sealing is sprayed at random as a whole, forms anti-counterfeiting information figure, and anti-counterfeiting information figure is acquired, is handled, and is uploaded
To anti-counterfeit server, mobile client can judge the true and false of the commodity using this anti-counterfeiting technology by anti-counterfeit software.
Background technology
Since the extensive transaction of commodity starts, anti-pseudo problem is just taken seriously along with commodity transaction.Briefly, prevent
Pseudo- technology is to ensure the technological means of certain commodity authenticities, and authenticity is the premise of the sustainable transaction of commodity.
Anti-counterfeiting technology is finally necessarily applied on commodity, using specific anti-counterfeiting technology commodity the characteristics of be by that can inquire
Mode ensures the authenticity of commodity to be purchased, and ensures commodity authenticity and seek to ensure the uniqueness of commodity itself, can test
Card property, authenticity.
The development of anti-counterfeiting technology is a very long history, but forges technology but also can find the leakage of anti-counterfeiting technology
Hole.Therefore, there is presently no fundamentally solve efficient anti-counterfeiting technology problem.
Efficient anti-counterfeiting technology has to meet following four " anti-fake four rules "：Easy anti-pseudo-operation；Easy is anti-
Dummy check mode；Anti-counterfeiting technology can protect end article；Anti-counterfeiting cost is no more than the 2% of commodity price.This four rule is mutual
Supplement is eventually exhibited as forging the cheap namely anti-fake efficient of the high and anti-counterfeiting cost of cost.
Anti-counterfeiting technology of today is much developed, and mainstream anti-counterfeiting technology classification mainly has three classes：Information technology is anti-fake, material
Material technology is anti-fake, mechanical technique is anti-fake.
The anti-fake mode of information technology mainly has：Traceability anti-fake system, electronics verification are anti-fake.Material technology is anti-fake mainly to be had：
Physics optothermal material is anti-fake, chemical material is anti-fake.Mechanical technique is anti-fake mainly for the anti-fake of the particular envelopes such as such as bottle packaging.
The anti-fake mode of information technology is to pass through this commodity sign code to every unique commodity sign code of commodity one
The information of commodity can be retrieved and be corresponded to, examines end easy to operate.Traceability system is capable of providing commodity from raw material, production, stream
All information during logical, these information constitute effective evidence of commodity authenticity.But traceability system needs manufacturer, sells
Quotient provides a large amount of information, and link is more in the collection of information, generalization procedure, contains much information and miscellaneous, leads to anti-counterfeiting cost
Amplification, anti-fake efficiency are low.Electronics investigates the anti-fake scaled down version that can be regarded as traceability system, can only provide whether commodity are detected
It the basic information such as crosses, has been phased out.It askes and causes it is emphasized that the anti-fake mode of information technology is susceptible to false drop
Anti-fake failure is easy to be imitated since the anti-fake technical threshold of information technology is very low.
It is the mainstream of anti-fake mode all the time that material technology is anti-fake.Material technology is anti-fake to be easy to when manufacturer carries out anti-fake
Operation, but the inspection knowledge for having certain is needed when customer checking.Different commodity are due to the use of different anti-fake materials, so leading
Cause the anti-fake check experience of consumer excessively poor.On the other hand, once material technology is hacked, antifalse effect fails immediately.
The anti-fake application surface of mechanical technique is very narrow, can only often play anti-without role of inspection.Meanwhile machinery
Technology is easy to be hacked, and antifalse effect is easy failure.Other forms anti-counterfeiting technology can only be coordinated to use.
Picture it is anti-fake can extensive use, but in the prior art, because of factors of the figure in gatherer process, such as
The factors such as lens distortion of the torsional deformation of picture, the difference of picture collection equipment pixel, picture collection equipment, so in picture
The comparison technology of element also becomes the technical issues of restricting anti-counterfeiting technology development.
In view of the foregoing, invent it is a kind of it is simple and practicable, at low cost, easy to operation, convenient for commodity true and false verification it is anti-fake
Method is with regard to particularly important.
Applicant had submitted on May 16th, 2017 application No. is：201710340652.3 entitled：A kind of overlay code is anti-
The system of fake method and application this method, the random pattern that this application is just researched and developed are formed by overlay code anti-counterfeiting technology and have carried out in detail

Some, so, to further increase the comparison technology of random pattern, reducing anti-counterfeiting cost, applicant carried on January 17th, 2018
Handed over application No. is：201810045811.1 entitled：" utilize the anti-fake side of random sprinkling figure and digital picture correlation technique
The patent application of method and application ", in this way, introducing the concept of wide ratio, the letter to the commercial product identification represented based on bar code
For breath in conjunction with pixel technology, can more accurately determine sprinkling spot includes central point transverse and longitudinal coordinate, realization precise value（It is wide
Than being added）The information collection of random speckle is perfectly become the anti-counterfeiting information of number by the computational methods of+estimated value, to real
The digitlization comparison of existing random figure.But in 201810045811.1 patent applications, because random pattern is to be sprayed at representative
It, can be to follow-up if the pattern then sprayed covers the identity information of commodity on the encoded information layer of commercial product identification
Verification process formed obstacle, although the optimal technical scheme of the patent application document uses body of the bar code as commodity
Part information can evade this problem, but with the development of commercial product identification information technology, the new representative commercial product identification such as Quick Response Code
The coding mode of information can continue to bring out, then the technology in second part of patent application document there is lacking in terms of applicability
It falls into, applicant carried out further research and development thus.In addition, color is very heavy, the drying hardening problem of the prodigious spot of thickness is
Restrict a great problem in random speckle forming and hardening in random spray application.
