Description
【Technical field】
The present invention relates to a kind of Anti-counterfeiting seal system and seal making methods, know more particularly to a kind of matching artificial intelligence auxiliary
Other system can anti-the 3D printing Anti-counterfeiting seal system and seal making method forged.
【Background technology】
Epoch in progress, fake also in progress.
At present, with 3D printer, especially laser three-dimensional scanning（It is widely used in mould applications.）, high-precision
The popularization of sweep optical square and high-precision 3D printer and widely available, the Yi Jiyong of frosting plating metal film technique
In the microscopic carvings electric tool of engraving, lapping tool can arbitrarily be bought, and the cad technique that scalar image turns vector image is general extensively
And.There is the case for the seal forged using the above method！Its exquisite and high emulator, allows existing security stamp
Failure.By analysis fake producer mainly make use of " 3D printer+metal coating thickens+printed circuit lithographic technique+microscopic carvings electricity
Power driven tools reparation ".These seals forged allow banking system to be unable to cope with, and result in many companies in deposit at bank, suddenly
It loses.（Mainly, forge cash on bank and the mode of check only for account transfers.Certainly, blank check is genuine that seal is false.
Too advanced, the basic None- identified of banking system that only these seals are forged.）And the case of falsification of seal loan, it forges
The legal case for occupying private company's property of seal is very startling.And on black market, this " fine work " security stamp,
Only 10,000 yuan one.Either with or without the falsification of seal that higher is imitated, we are unknown.Simply know, in the side that the later stage repairs
Respectively there are unique skill in face, each fraud clique.Its machining accuracy has been over 0.1 millimeter of rank.Error 0.02 is had reached
Within millimeter.（It is equivalent to after 10 times of amplification, also within 0.2 millimeter, people's naked eyes identification range！）, and identical seal,
On different papers, using different ink, how much it is stained with ink, 0.2 millimeter of error is just present between this！
Which results in your security stamp of security stamp and fake producer on hand on hand, the effect for covering out is completely the same, silver
The systems such as row, law court, basic None- identified.
As background technology, there has been the technology of substantial amounts of security stamp in the country, and according to quantity, it is big to be broadly divided into five
Class.
Wherein, the first kind prevents unauthorized use（Seal is genuine！）Class；This kind of background technology and the purpose of the present invention
It is unrelated.This is also security stamp, not as good as being referred to as, anti-unauthorized use seal, more properly.Its technical characteristic substantially with
It prevents to fake as purpose anti-counterfeiting behavior, no essence association.
Such as Granted publication： CN205970438U《A kind of remote control is by the Intelligent anti-counterfeit seal for printing the time》
Wherein, the second class is confused about anti-counterfeit measures are which kind of fraud pattern resisted.Namely increase chip class, I does not
Understand that overwhelming majority falsification of seal are provided to cover seal on paper, as long as the seal forged can allow key person（Such as bank
Personnel,）None- identified it is true and false can, do not understand fake producer why to forge the inside chip；Fake producer uses
During dummy seal, it is also necessary to supervised to use；When fake producer uses dummy seal, it is also necessary to put on record to bank.For fake producer,
This is something completely without forging meaning.It more does and does not understand, in what situations, fake producer can use the chip of the inside.Cause
For when enterprise opens an account with the bank, when leaving seal seal archives, bank is that requirement legal representative appears in person, and is difficult to understand for
Legal representative is opened an account with the bank this kind of event with dummy seal.This is a kind of, is not know the purpose classification for preventing fake producer or only limit
Dummy seal, which is manufactured, in confrontation legal representative itself gains this extreme event that opens a bank account by cheating；（If it is to fake to truly have legal representative
Person in itself, then involves that interests are centainly huge, and probably a chip is the cost that can't hold out against 100,000 U.S. dollars or even million U.S. dollars
's.In addition legal representative is that have method to forge the seal of oneself enterprise by legitimate channels or get around.Concrete mode is：
Legal representative of enterprises is first opened a bank account with the legal seal for having chip a certain；Formality to be finished, then all seals are reported the loss, then
New seal is handled, then is opened a bank account again other with new seal, the bank to have opened an account without informing this family replaces print
Mirror.This is a simple and unmatchable fraud thinking.In addition at this stage, using dummy seal, false license is done again, in bank
The event opened an account is too odd.But this is the standard configuration of the domestic security stamp applied at present.
This is also the thing that a worker for having 20 years or more anti-counterfeiting technology experiences does not understand.It is to be understood that increase and upgrade
Seal chip, wastes how many financial resources and material resources.）, increase chip and be the increase in forgery difficulty, it still, but must without what is forged
The property wanted, fake producer need not forge chip therein and just achieve the purpose that fake, and the improvement of this technology does not have with antifalse effect
There is direct relation.Hold reservations in one's own possession.

CN202702908U《The metallic security seal of electronic label》
CN202319316U《A kind of security stamp with information-storing device》
Wherein, three classes increase random info class；（Such as number, such as changing patterns）This is a kind of.I do not understand really how
Accomplish to allow long-range identification person, identification is true and false.Your change information every time；（The apparently people of bank will also make a phone call to verify every time
The pattern of variation or the content of number；）Difficulty except increasing identification person, it is difficult to which new trouble can be brought to fake producer.It is this
The improvement of technology, it is therefore an objective to it is good, do not improve its antifalse effect, but add cost.It adds simultaneously, in data falsification storehouse
The weakness that the new needs of verification characteristics are taken precautions against.And the manufacture difficulty of the print protected face part is really needed not increase.

Wherein, the 4th class is the technological invention for resisting fake producer's falsification of seal behavior.Application after we select 2010,
Applied before 2010, fake producer hardly knows 3D printing.
Such as Patent application Publication, CN204641108U《A kind of security stamp》It is described, by the use of random point as anti-counterfeiting characteristic.
Simple pit is easy to artificial " drawing " out on the CAD software of 3D；Using " metal coating thickens+throw flat " pit
Natural edge is even more " clear, natural ".Moreover, the processing technology of pit, seems simple, it is in fact very complicated！It is very without instrument
Hardly possible realizes the making of the pit.And using instrument, then it is easy to by identical instrument or alternative instrument, Clonal forgery
's.This point is especially apparent especially on metal material seal.How natural " pit ", obtain and manufacture, inherently
A technical barrier！And mechanicalness " pit ", then it is easily cloned.
Such as Patent application Publication, CN103802512B《A kind of production method of security stamp and its anti-counterfeiting technology》It is described,
By the use of anti-fake, figure Quick Response Code of micro text and pattern etc. as anti-counterfeiting characteristic.After 3D printing is used to forge, then paste " printing
The print face problem that circuit lithographic technique " is forged；In addition for the counterfeit of high value, purchase micro text and pattern tools,
It is also easy thing to rent electric spark.
Wherein, the technological invention of the 5th class and confrontation fake producer's falsification of seal behavior.The technological improvement of selection but more
Route is increase ink or carries various ink（Ink paste）Etc. the print face structure and production method of non-improvement seal.This is a kind of,
Style is numerous and diverse.The shortcomings that common, is, once the print face of seal is forged successfully by fake producer, the various skills of increased patent application
Art means are all easily found interim replacement solution.For example, manually finding similar ink, manually addition is in print face
On.When forging seal anyway, only at the scene, nobody supervises fake producer oneself.

In conclusion for the direct forgery in print face, it is where the final purpose of fake producer, is needed most in itself also for seal
Anti-fake part.And can resist " 3D printer+metal coating thickens+and printed circuit lithographic technique+microscopic carvings electric tool repaiies
It is multiple " mode of new generation directly fake the technological improvement in print face, be blank.
The purpose of the present invention is：By establishing system, solving fake producer's use, " 3D printer+metal coating thickens+printed circuit
The fraud technology of new generation of lithographic technique+microscopic carvings electric tool reparation ", the anti-counterfeit of seals that Direct Cloning type copys false print face are asked
Topic.Allow fake producer skillful craftsman fake product, in face of the integrated anti-counterfeit power of system, reveal original shape or can not copy at all

It is metal stainless steel and ferroalloy, duroplasts, animi resin and resinous product, hard rubber, horn or tooth, stone, jade, hard
The materials such as wood, bamboo, crystal glass, ceramics.
It is further characterized in that：It is the coordinate point feature that " punching, tapping, the turn of the screw " makes that the seal, which increases anchor point,
Screw is metal, can be different from seal material, and screw is（With screwdriver class, internal angle wrench class instrument）It is connected and is fixed on seal
, adhesive or curing agent can be used when affixed, include but not limited to be lead oil, AB glue, epoxide-resin glue, curable sealing
Glue.
It is further characterized in that：The screw is fixed on the broadside of seal；Cap nut can protrude from the broadside of seal；Number
Amount can be one or more, and the diameter of cap nut can be different, can vary.
It is further characterized in that：The seal increase with steel seal get pit or with steel seal get pit dispatch from the factory number or letter
Number；Due to the feature difference cut of steel seal, and new manufacture difficulty is added, add the new elements of a fix.
It is further characterized in that：Also increase the two-dimension code pattern of useful mechanical stamping or laser engraving on the seal；Or gold
Belong to scriber mark, hard metal shocks, laser engraving, with 3D printer part（Metal）Printing, electric spark locally carve manufacture
Word, pattern, symbol, figure, lines.
The seal making method, it is characterised in that：
The first step is to make seal material；
Second step is punched in chapter material plane, tapping；
3rd step is in screw hole plus glue and is connected fixed screw；
4th step, with slightly frustrating chapter material plane；
5th step carves characters in chapter material plane, seal is made；
Or implementation steps in proper order reverse.
The implementation steps in proper order reverse, is that the order of above-mentioned procedure of processing can be upset, precedence can overturn, generally
Its processing result is not changed, simply implementation cost is slightly different.
It further illustrates：
Traditional process equipment.Such as drilling machine punching, the deviation in the random margin of tolerance may be caused；Exactly anti-counterfeit measures it
One.
The screw surface manually to tighten the screw, the surface for being rugged or even indivedual screws is " crooked "（Drilling
Deviation occurs for not fully vertical or manual tapping.）；And " trace " of the individual style formed；（Screw is screwed on, in screw hole
Fluid sealant as the leading oil of side；）Dynamics differs, and the depth of screw is inconsistent, and the direction of notch, groove on cap nut is not yet
Together.Exactly one of anti-counterfeit measures.
Multiple screws, multiple apertures, screw are manually tightened up a screw；Very round thin side is left at screw hole！The sharp figure formed
Shape；Non-concentric is formd between screw and screw hole；With being examined after amplification, " edge roughness, an edge are tough and tensile
Clearly." specific characteristic.（Brass processing after, edge " soft " and it is coarse and CARBURIZING FURNACE FOR STAINLESS FASTENER edge " hard " and it is careful.）Exactly
One of anti-counterfeit measures.
Row frustrates process, it is of course possible to use special machinery.
But it is difficult to be consistent manually to frustrate flat dynamics；In addition " flat to frustrate " natural defect for frustrating tooth of itself, causes to frustrate
The section of trace is not the circle section of complete " semicircle ".But as " gully ", internal " bumps " injustice, be " more
The special track of the parallel propulsion of winding displacement item, the common depth "；Be have " row frustrate direction " by deep and shallow gradual change, this gradual change is
It can be seen that the processing stand of processor and terminating point at that time, are exactly one of anti-counterfeit measures.
During the teeth of " flat to frustrate " promote, brass and stainless steel are run into when soft or hard metal transfer, can be generated bright
" jump " of the aobvious trace depth；And the trace is " coherent " feature；Human eye can clearly differentiate, be " line "；
Since every is frustrated trace, have surrounding as " processing of screw hole, the groove of the turn of the screw of screw surface, screw surface squeezes flower
Line " other " frustrating trace " is used as object of reference；The forgery deviation of a little；It will be under magnifying glass " clear and legible ".
And " punching, tapping, the turn of the screw " makes coordinate points and can leave " manually flat to frustrate " of " complexity frustrates trace "；It is formed
Trace " track ", be controllable！In terms of macroscopic view, " row frustrate " direction and the angle of processor can be controlled；It is formed special
Different " path "；The new trace information features such as lines confusing cognizable special " figure, word " can be formed.
The above-mentioned fine and processing of the machine tool of gradual change natural vector 3D features；The reason is that 3D printer " simulate by scalar
The essential processing technology of vector " can not be simulated and.If simulate this natural vector 3D features；Machinery must be used
Instrument is processed！And these fake producers can not arrive.
The depth that the coordinate point feature and " manually flat to frustrate " made by " punching, tapping, the turn of the screw " leaves is uneven but continuous
Numerous " complexity frustrates trace " formed linear feature；Form the feature for being difficult to replicate.And these features, all can with stamp-pad ink and
It is transferred on paper！Want shallow all shallow, deeply all deep.And regular it can differentiate.Namely " there is identifiability ".In addition
Other feature, the comprehensive print face formed, being can not be exquisite imitated.
In terms of amplification pattern, the feature of processing technology is apparent, especially some of which " details ".
Certainly, traditional manufacturing process is also what is included, such as the operations such as laser boring or cutting, hemisect edge.
The material of screw and copper Zhang Butong；Such as stainless steel；The deep mixed cause of trace is so frustrated, forms new anti-counterfeiting characteristic.No
The material of same screw is also different；Have it is hard some such as stainless steel；There are copper, soft such as aluminum screw, material difference is similary
Cut under pressure frustrates trace, hence it is evident that different.
Impression is since the stubborn elastic difference of screw and the depth of screw hole are different；Screw perpendicularity is different；And it is formed
Different high points；These high points naked eyes may differentiate unclear；And on amplification pattern；It can be seen that its difference.
The security stamp of manufacture forms system for the identification facility of core with artificial intelligence, matches use.It can be only achieved the present invention
Desired effect.
At standard conditions（Use identification terminal equipment）, the picture of the amplification of acquisition is uploaded to long-range artificial intelligence
Identification center；Even if very tiny difference, and in larger disturbing factor, such as have signature, the original pattern of paper background, lid
The depth of chapter is different, under stamp-pad ink how many difference etc. environment.Also can be identified clear.The purpose of the present invention is reached.
