Description
Technical field
The present invention relates to a kind of financial machine and tool, be called Apparatus for testing paper currency for genuineness, be applicable to the true and false of printings such as differentiating banknote, securities, ticket, certificate, trade mark.
Background technology
At present, there is special criminal gang to aim at the automatic teller machine of bank, technical parameters such as their watermark by forging banknote, safety line, thereby reach the parameter index of some automatic cash dispenser approvals, counterfeit money will deposit machine in as genuine note like this, money has also been thrown offender's bank account into, and What is more, and the counterfeit money that external offender can not have banknote denomination picture and text unexpectedly with having only the high emulation anti-fake mark exchanges genuine note for from automatic teller machine.
Causing this situation, is not that the genuine note anti-counterfeiting technology is advanced inadequately, neither the police administers ineffectively, and it is also unwise to scold that counterfeit money is usurped high-tech means emulation.Problem is authentication technique itself.Existing various authentication techniques and products thereof all fasten one's eyes on sight the anti-counterfeiting characteristic and the mark of genuine note on the market, and are absorbed in undying harmful competition with counterfeit money, cause counterfeit money to be put down repeatly and do not go out, and wildness has and adds.
In GB16999-1997 " Renminbi discriminating machine for fake RMB " national standard, stipulating just has eight kinds at anti-fake mark or feature in nine kinds of identification methods, and need possess two kinds simultaneously with upper type; In addition, rate is debated in the leakage that also allows below 1/5000.This explanation, even meet the Renminbi discriminating machine for fake RMB of GB16999 national standard, its identification result is not still had an authority of award in final.This standard formulation only was applicable to Renminbi in 1997.Since 97 years, huge advance made has taken place in world technology, and the counterfeit money manufacturing technology grows with each passing hour, and our standard in 97 years also this has upgraded.
Genuine note and counterfeit money all are chromatograps.Genuine note is the legal tender of government issued, belongs to extraordinary chromatograp.For false proof needs, government is inevitable secret formulate special-purpose, different fully with the common color printing and never together currency printing technology standards system and tight security monitoring system.Xiang Guan technology, technology, raw material, equipment can not be let out among the people therewith.This point, any country is not always the case.Genuine note printing micro-image has following " strain line structure " feature.Counterfeit money belongs to the common color printed matter, though its how to make, how fineness all is the product of common color printing technology international standard system.This international standard system contains: flat stamping, gravure, bite, flexo and electronic scanning, laser photo-typesetting, color photocopying, laser printing, digital color printing, digital photographing or the like.Its image is made up of pixel (being the site), thereby its printing micro-image has following " lattice point structure " feature.The offender is limited by disguise, ageing, practicality can only be utilized this type of common color printing technology and equipment crime.
The basic theory of common color printing technology is the printing colorimetry.Its studies how to describe (i.e. printing) coloured image in batches on physical supports such as paper: only need mix to show the various colors of occurring in nature in theory with blue or green, pinkish red, yellow three kinds of primary colors with addition, in the practice (being printing technology) to add black in addition just black to obtain, so claim four primary colours, simultaneously, be picture breakdown that pixel is that the site is with the implementation space colour mixture.Therefore, it is the most basic principle of common color printing technology.The fm screening new technology is used this principle too.
In sum, different colored printing technical standard systems are true just, the essential distinction between counterfeit money, the gross differences of micro-image architectural feature therebetween, the gene that can be compared to bion are the same, congenital intrinsic, can't evade forever.This is only the fatal key of counterfeit money.
I once had the patent of application number 03253229.6 " micro-money identifier " by name, belonged to the pure optical microscopy device of double image screen video picture.Its shortcoming is: 1, two optics picture screen distances are very near, are applicable in the bank counter and use that if place sales counter to allow client use, then the personnel of bank are difficult to know banknote who is real and who is false in client's hand, more can't realize monitoring synchronous video outward; 2, inconvenient law enfrocement official moves use; 3, optics picture screen dark images is light; 4, harsh to light source and each optical element technology parameter request.
Before this, invention was once arranged: 94212047.7; 94215271.9; 95245454.8 number patent.All do not touch the genus of colored printing technical standard and " strain line structure ", " lattice point structure " in these three patent specifications, but cooperate true and false coin characteristic feature identification collection of illustrative plates by graduated scale, grid calibrated dial, observe the sharpness of the interior lines of the every grid of same position on the true and false coin respectively, number of lines and line footpath or diameter are as the discriminating standard.This effect and magnifier are as good as, thus do not have advance, also impracticable.
