Description
Technical field
The present invention relates to a kind of to anti-counterfeiting mark Antiforge recognizing method.
Background technology
The fast development of market economy, promotes the diversification of market product and rich, sufficiently full
Foot consumer demand.But meanwhile, imitation, fake products also substantial amounts of appearance, have a strong impact on
Consumer and the interests of user.Particularly with some famous brand name products, once occur that fake and forged commodity is produced
Product, will bring immeasurable loss to society and enterprise.The production of these famous brand name products, stream
Lead to, use and keep in repair, it is desirable to have safe and effective false proof and tracking safeguard.
Current bar code, Quick Response Code are extensively made, for commodity logistics, store in a warehouse, review, false proof etc.
Aspect, it has can be distinguished by mobile phone, it is easy to the characteristics such as consumers in general use, cheap, but
It there is also and is easy to imitated, the low feature of anti-counterfeiting power.And high-tech common in the market is false proof
Method, as fluorescence falsification preventing, retroreflecting is false proof for orientation, magnetic anti-counterfeit, antiforge laser holographic, watermark
False proof etc., it is required for specialty detection instrument or there is to consumer the identification skill set requirements of more specialty,
It is unfavorable for being accepted or used by consumers in general.Wherein, magnetic anti-counterfeit mainly passes through magnetic ink
Constitute character, pattern etc., use the special detection device detection specific magnetic signal authentication true and false, its drawback
It is owing to the environment of ours at one's side also existing substantial amounts of magnetic interference, such as earth magnetism, all kinds of electromagnetic interference
Deng the fixing quantity difficulty of therefore magnetic induction characteristic is higher, especially for the amount of low magnetic induction intensity
Fractional analysis.Magnetic induction characteristic is applied to anti-counterfeit field, especially on anti-counterfeiting mark, its magnetic induction material
The consumption of material is little, and magnetic induction intensity is very low, how to shield the magnetic interference of environment, correctly knows
Other feature magnetic induction signal, and identified by the public is false proof, just become anti-counterfeiting technology and be proved to be successful application
Key.

The magnetic induction numerical value B1 of anti-counterfeiting mark, record anti-counterfeiting mark magnetic induction signal reaches numerical value B1 institute's used time
Between H2；
And by the gyroscope components and parts in mobile phone, determine direction residing during mobile telephone scanning antifalsification label,
And choose the corresponding magnetic induction numerical value C1 of approximate direction therewith, by C1 and anti-counterfeiting mark magnetic induction numerical value
B1 is added, it is thus achieved that E, to carry out corresponding directional compensation；
One of the described approximate direction earth magnetism numerical value referring to all directions of measured in advance direction
Earth magnetism numerical value, residing when described direction and mobile telephone scanning antifalsification label direction approximation；
In step (1) and (2), numerical value C1, B1, A1 and H2, all false proof by mobile phone
Identify that software calculates accordingly, open anti-counterfeit recognition software consumer and use mobile phone sensing anti-
During pseudo-identification marking, cell phone software is automatically performed above-mentioned steps (1) and (2)；
(3) authenticity verification, verification method is as follows:
1., when A1 exceedes the setting interval numerical value D1 upper limit, illustrate that environment exists ferromagnetism interference, terminate
Detection program simultaneously points out user change detection environment or again detect；
2. E is within the interval numerical value D1 of setting, and H2 is positioned at the interval numerical value H1 of setting, i.e.
It it is believed that anti-counterfeiting mark is genuine piece, otherwise is then counterfeit product；
Sensing element device involved in above-mentioned recognition methods, gyroscope components and parts etc. are current intelligence
Mobile phone standard configuration, the judgement of above-mentioned condition value can be completed rapidly by cell phone software, consumer
Only needing starting hand-set corresponding anti-counterfeit recognition software, scanning anti-counterfeiting mark, cell phone software can quickly be distinguished
The true and false of other product, it is not necessary to consumer is more by virtue of experience or the detection instrument of specialty is distinguish true from false.
The present invention is a kind of by mobile phone sensor part sensing specific magnetic induced signal, and passes through certain
Method resolves the Antiforge recognizing method realizing a kind of low cost, being easy to detection, of the present invention anti-
Pseudo-recognition methods also can combine with the information technology such as bar code or Quick Response Code, by magnetic induction anti-counterfeiting information with
The information technology such as bar code or Quick Response Code is associated, and information technology is traced to the source for backstage and reviewed, magnetic induction skill
Art is cracked down on counterfeit goods for false proof.It by the first scanning barcode of mobile phone camera or Quick Response Code, is then turned on follow-up identification
Step, forms the bi-directional verification of information tracing and anti-counterfeiting technology, further improves anti-counterfeiting technology wall
Build, reach the purpose of multiple anti-fake.
