Description
One, affiliated technical field:
The present invention relates to a kind of encryption and method for anti-counterfeit of ticket, particularly a kind of ticket based on sign fiber stochastic distribution is encrypted and verification method.
Two, background technology
Various bills (for example check, draft, cashier's cheque, banknote, stock, tax invoice, customs declaration list, savings centificate etc.) all are the important evidence that has important economic worth and be used to confirm individual or unit identity with certificate (for example I.D., employee's card, officer's identity card, diploma, passport etc.), and these tickets are using widely in China and countries in the world.Because this class ticket is in the vital role in economic and social life field, the criminal activity that forgery of negotiable instrument carries out various swindles exists always and grows in intensity, become a big hidden danger of financial security of the country and social stability, so ticket anti-pseudo becomes current research topic with great economy and social benefit.
The ticket anti-pseudo major technique is both at home and abroad at present: (1) prints additional the watermark of various patterns on ticket, (2) add a cover entity and individual's seal in the specific region of ticket, (3) add the artificial password that generates and it is write on the ticket, in order to checking, take measures on the printing technology of ticket (4), for example adds tinsel, adopt magnetic ink etc., (5) it is false proof to utilize optical principle to carry out, and for example utilizes the specific secret mark of UV-irradiation, utilizes laser antifalsification technology etc.
Though above-mentioned anti-counterfeiting technology can suppress the generation of forgery of negotiable instrument phenomenon to a certain extent, can not fundamentally stop the problem of forgery of negotiable instrument.This is because all anti-counterfeiting characteristics of bill that utilize above-mentioned anti-counterfeiting technology to generate are all determined.For example, be extensive use of the watermark anti-counterfeiting technology in banknote, important securities and certificate, with a kind of banknote of face amount or with a kind of certificate, these watermarks not only pattern are identical, and the position that occurs is also identical, does not have individual difference.Beginning to add colored fine fibre in the high face amount banknote of China and some country is used for preventing forging.
Up to the present, no matter be to adopt digital watermark and other the relevant anti-counterfeiting technologies that does not have individual difference, also be to use the colored fine fibre anti-counterfeiting technology of individual difference, their starting point all is to use watermark, the difficulty of colored fine fibre on making prevents to forge.In science and technology highly developed today, forging (clone), to go out various bills and the certificate that can mix the spurious with the genuine be not very difficult something.Therefore, it is false proof more and more difficult to only depend on the difficulty that increases manufacturing technology to carry out.The key that prevents forgery of negotiable instrument is invention and realizes that a kind of new method for anti-counterfeit and technology, his core are that selected anti-counterfeiting characteristic is a stochastic distribution, can't duplicate again simultaneously.Security in order to ensure ticket, except ticket itself needs to adopt the reliable anti-counterfeiting technology, also must be to the important content on the ticket, for example the amount of money of bill, seal, signature, date etc. take to prevent effectively to prevent the measure of altering, reaching not only ticket itself can not forge, and the ticket content also can not alter, and only in this way, just can guarantee the safe handling and the circulation of ticket.
Three, summary of the invention
The object of the present invention is to provide a kind of great primitive character of the randomness that forms in the bill manufacture process that utilizes as encrypting and false proof key element, formation (is included in the ticket carrier by the inherent feature of ticket own, promptly make the feature in the paper of using in the ticket process) and by the ticket content (amount of money for example, seal, signature, date, number etc.) the common ticket fingerprint of forming of the feature of mentioning in, differentiate by the inherent feature of checking bill whether ticket itself is forgery, whether differentiate ticket contents through correction by the content characteristic of checking bill, thereby the ticket based on sign fiber stochastic distribution of guaranteeing ticket safe handling and circulation is encrypted and verification method.
Realize that technical solution of the present invention is: a kind of ticket based on sign fiber stochastic distribution is encrypted and verification method, it is characterized in that: it is encrypted by ticket and the ticket proof procedure is formed, the ticket ciphering process is: 1. the operator signs and issues the ticket that contains colored marking fiber inherent feature, fill in the ticket content, form the ticket content characteristic; 2. the ticket that will sign and issue is put into the Color Image Acquisition device scan; 3. the ticket process computer extracts ticket inherent feature and content characteristic; 4. with inherent feature and synthetic ticket fingerprint of content characteristic and coding; 5. the ticket finger-print codes is converted to two-dimensional bar; 6. two-dimensional bar is printed on a certain zone of predetermined ticket; The ticket proof procedure is: 1. the ticket that is verified is put into Color Image Acquisition equipment and scan; 2. in the ticket image, detect two-dimensional bar; 3. two-dimensional bar is decoded; 4. according to decoded information, verify the inherent feature in the ticket image; 5. according to decoded information, verify the content characteristic in the ticket image; 6. forgery of negotiable instrument and correction ticket content are carried out comprehensive distinguishing and analysis, provide the comprehensive distinguishing result.
The bill inherent feature is to be used for preventing the key feature that bill itself is forged, therefore, in bill carrier manufacture process, just use in the manufacture process of paper at bill, mix into colored marking fiber in paper pulp artificially, this colored marking fiber can be used making such as vegetable fibre, plastic optical fibre, tinsel.Parameter such as the diameter of this colored marking fiber, length, color and at one page ticket with the shared area ratio of colored marking fiber in the paper, in production technology, can control and regulate fully, each page ticket with paper in the orientation of the distribution of colored marking fiber and each root colored marking fiber then be at random fully, unrepeatable.
Extraction and processing in order to ensure inherent feature are carried out easily, and the diameter range of the colored marking fiber that uses is the 0.3-1 millimeter, and colour is red, blue, green, yellow, black.After the bill carrier that contains the colored marking fiber is made, can print various blank tickets by special enterprise.After ticket was signed and issued out by applying unit, this ticket just became both to have included inherent feature, has also included the spendable ticket of content characteristic.
The inherent feature of extracting ticket is exactly position and the parameter that the colored marking fiber that will contain in the ticket detected and extracted every colored marking fiber.For this reason, can be with the Color Image Acquisition equipment of any resolution more than 200DPI, color scanner for example, colour TV camera are gathered the ticket image and with its input computer for further processing.
In order to improve the intensity that ticket is encrypted, the four corner of ticket is not carried out the extraction of inherent feature usually, but leave a rectangular window as the inherent feature pickup area selecting on the ticket artificially with mouse.Window is once selecting the size in the position of the automatic record window of system and zone.In order to ensure the reliability of secret, should comprise the colored marking fiber of non-solid color more than five in the common selected window.System accesses the part bill image corresponding with window, and this parts of images is carried out the processing and the analysis of bill inherent feature according to selected window in the bill image.
The edge detection algorithm that to the effect that utilizes image and the edge track algorithm of Flame Image Process and analysis in selected zone, extract all colored marking fibers and calculate the parameter of each root colored marking fiber.These parameters comprise reference position (coordinate), diameter, direction (coordinate point sequence with the colored marking fiber is represented), color of each root colored marking fiber etc.These parameters identify the existence form of fiber characteristics with regard to having represented that uniquely ticket carrier (paper) is enameled, be after the ticket carrier completes and the actual ticket inherent feature of using (signing and issuing) preceding existence, this feature generates in making ticket carrier process at random.It almost is impossible generating identical two the ticket carriers of inherent feature, and this characteristic also of the present invention has just guaranteed that the ticket with this feature has very high anti-counterfeiting performance.
The formation of ticket content characteristic and extraction.Can not forging of ticket (sign and issue use before blank ticket) itself can not be guaranteed ticket security in use fully, and this is to remain dangerous in the staff that the swindle attempt is arranged because blank ticket or the ticket signed and issued have been fallen.They can interiorly perhaps revise the purpose that the legal content of having signed and issued on the ticket reaches swindle by what add to need on blank ticket, such as, can scribe the signature of required seal of adding a cover on the ticket, imitation signed by, the account number that reaches out for legal account holder, the related content (for example amount of money) of altering the issuance of a note voluntarily and wait the purpose that reaches swindle.For the real ticket safety problem that solves, also must encrypt with false proof the content of ticket.
Different tickets comprises different contents, and the cashier's cheque of signing and issuing with the maximum bank of content here is formation and the extracting method that example illustrates the ticket content characteristic.For cashier's check, the ticket content comprises two parts, and first's content is the anti-counterfeiting characteristic that adds in ticket manufacturing process, and the second portion content is to sign and issue the artificial information that adds in the process at ticket.In cashier's check, the anti-counterfeiting characteristic of first comprises watermark, filament, magnetic ink, ultraviolet band sensitivity pattern etc., though these anti-counterfeiting characteristics also can be thought foregoing inherent feature, essential difference is arranged with the colored marking fiber characteristics.The colored marking fiber is in ticket carrier manufacture process, adding colored fiber in paper pulp forms, the position that these colored marking fibers occur in the ticket carrier, direction, distribution all are at random, and any two blank ticket carriers do not have identical colored marking fiber characteristics.And the anti-counterfeiting characteristic of specially printing on the blank ticket, for example watermark, filament, magnetic ink, ultraviolet band sensitivity pattern etc. all are identical to any two similar tickets.The second portion content is included in cashier's cheque and signs and issues artificial seal, Chinese character and the arabic numeral amount of money, the date etc. that add in the process, this bank is understood in the correction of the amount of money in this partial content cause direct economic loss.
First's content in the ticket carrier, for example watermark, filament, magnetic ink, ultraviolet band sensitivity pattern etc. are compared with the present invention, and security is obviously on the low side, die and only it is verified, and need not generate the feature of the ticket fingerprint of the present invention's proposition.Second portion content on the ticket carrier, for example cashier's check is signed and issued the artificial seal that adds in the process, the Chinese character and the arabic numeral amount of money, date etc., it is the main foundation that generates the ticket content characteristic, cardinal principle and the process of extracting content characteristic are as described below: the definite range searching seal in the ticket coloured image of importing at first, the Chinese character and the arabic numeral amount of money, content informations such as date, then with the Chinese character that extracts and arabic numeral respectively to level and vertical direction projection;? the form that exists that these content informations have been represented in two projections truly, is to differentiate the important evidence of whether being altered.Then extract the positional information of seal image, extract the coordinate on four summits for the rectangle seal, extract the round center of circle and radius for circular seal, these parameters can be described the geometric position of seal image in ticket fully.The precise geometrical position that these ticket important content information appear in the ticket carrier is the key feature that prevents to forge and alter the ticket content, because no matter be to alter the ticket content, still the forgery of negotiable instrument content ticket that all can't accomplish to make position that these ticket contents occur and quilt to be copied is just the same.The minimum precision of the Color Image Acquisition equipment that uses is 200DPI, the lowest positioned precision is 1/8th millimeters, at present, the color scanner bearing accuracy of 600DPI is up to 1/32nd millimeter, and it is impossible that the adulterator wants to make ticket content information (for example amount of money or seal) just the same with the ticket of being copied with high like this bearing accuracy.
The coding of ticket enciphered message.After the extraction of having finished above-mentioned ticket inherent feature and content characteristic, adopt the bigger two-dimensional bar of information capacity.One-dimensional bar code is to represent information with chequered with black and white striped, and when the quantity of information that is expressed was big, this method for expressing needed bigger space.Two-dimensional bar then is that chequered with black and white square comes expression information, he only encodes unlike common bar code in one direction, but encodes on both direction, therefore, on area identical, the quantity of information that two-dimensional bar can be represented will be far longer than common bar code.The present invention has adopted the PDF-417 two-dimensional bar coded system of widely using in the world.At first various parameters and data order and the form in accordance with regulations that the inherent feature extracted and content characteristic are comprised encoded, be PDF-417 two-dimensional bar figure with this coded representation then, and this figure be printed on the fixed area of ticket carrier with laser printer.In order to increase the anti-counterfeiting performance of system, adopt off-gauge PDF-417 two-dimensional bar, general bar code reading device can't be understood, and has only system designed according to this invention correctly to understand.PDF-417 coded system with standard is the same, and the present invention has adopted the Read-Solomon error correction coding in two-dimensional bar, makes when system's existence is disturbed than very noisy, still can correctly separate and read two-dimensional bar.
The ticket checking.1) adopt the Color Image Acquisition equipment (be generally plate color scanner) of resolution more than 200DPI will be tested the ticket image input note validating system of conclusive evidence; 2) the ticket verification system carries out space of a whole page topological analysis to the ticket coloured image of input, utilize the priori and the image Segmentation Technology of relevant ticket page format, from the ticket coloured image of input, be partitioned into the zone of having printed two-dimensional bar, and read this two-dimensional bar; 3) according to the coding rule of non-standard PDF-417 two-dimensional bar, the two-dimensional bar that reads is understood, thereby drawn the series of parameters and the data of ticket inherent feature and content characteristic; 4) according to separating the colored marking fiber collection district coordinate of reading, from the ticket image, read in the image of employed colored marking zone of fiber in the ciphering process; 5) image in colored marking district is analyzed and handled, detect colored marking fibers all in this zone, determine the parameter (origin coordinates, direction, diameter, color) of every colored marking fiber, think comparison with the parameter of given these colored marking fibers of two-dimensional bar then, see whether the two is consistent, thereby determine the true and false of ticket carrier itself; 6) from the two-dimensional bar sign indicating number that comprises of ticket coloured image of input, separate read every ticket content related parameter and data are arranged, determine the image-region at every ticket parameter place respectively according to separating the position coordinates of reading, and from these zones, utilize image processing techniques to try to achieve the parameter of response, to separate relatively consistance of the corresponding parameter of reading in the parameter of trying to achieve and the two-dimensional bar, thereby determine whether every ticket content is altered or forged; 7) consistance of comparison parameters is the process of a quantitative test, therefore, the quantitative identification standard must be arranged.Parameters used in the present invention is position coordinates, so the pixel of usable image is represented error.The real size that pixel is represented is relevant with the precision of the Color Image Acquisition equipment of use, and for example resolution is the image capture device of 200DPI, and the physical size of a pixel is 1/8th millimeters.Be used for differentiating the consistance quantitative criterion and be taken as 2 pixels usually.
The present invention compares with existing method, and its remarkable advantage is: utilize the colored marking fiber that adds in ticket carrier (paper) production run as the inherent feature of representing ticket carrier uniqueness, utilize the information processing technology to solve the false proof of ticket carrier; Utilize image acquisition and treatment technology from the ticket content, to extract content characteristic simultaneously and be used to prevent forgery and correction the ticket content, and above-mentioned two technology are combined, the content information that adds when ticket carrier itself (blank ticket) and ticket are signed and issued carries out false proof processing simultaneously, form each ticket exclusive " ticket fingerprint ", should " ticket fingerprint " can determine whether this ticket is that forgery or content are altered by checking, security is good, simple to operate, easy to use.Not to utilize the manufacture difficulty of ticket to improve the security and the anti-counterfeiting performance of ticket, but both utilized the inherent feature that forms in the ticket manufacture process, utilize the content characteristic that forms in the issue of bill process again.The inherent feature of ticket is the colored marking fiber of the stochastic distribution that forms in ticket carrier (paper) manufacture process, this colored marking fiber is stochastic distribution still not, can not occur fully accurately identical colored marking fiber on any two ticket carriers and distribute.Therefore, with the anti-counterfeiting characteristic of this ticket inherent feature, guaranteed that reliably the anti-of ticket carrier (blank ticket) itself is performance as the ticket carrier.Encryption to the ticket content, be to extract accurate position and shape description parameter in the content information the ticket after signing and issuing in essence, whether utilize these parameters to be easy to identify the ticket content is modified or forges, thereby guarantee the security of ticket content, not only guaranteed the not reproducible of carrier itself (blank ticket), also guarantee can not revising of ticket content, fundamentally guaranteed the security of ticket in using and circulating.
