Description

The method for anti-counterfeit of banknote, securities

Technical field

The present invention relates to a kind of method for anti-counterfeit, the method for anti-counterfeit of especially a kind of banknote, securities.

Background technology

China's anti-counterfeiting technology is under the condition of developing socialist market economy, and progressively formation and development is got up.Because legal system is still unsound at present, market is also lack of standardization, some lawless persons are in order to seek exorbitant profit both at home and abroad, special counterfeit famous-brand and high-quality and best-selling product, even a large amount of forged banknotes, stamp, various securities, resident identification card, residence booklet, diploma, official seal etc. have seriously been upset social economic order, become to hinder one turbidity current that China's economy develops in a healthy way.

Be example with the banknote wherein, existing anti-counterfeiting technology mainly comprises following several:

1. watermark: on copper mesh, carve out portrait or various figure during papermaking, when paper pulp flows into copper mesh, because the corresponding position of copper mesh depth difference has just formed the various figure watermarks of fibre density difference or depression after the pressurization.The bank note of the different denominations in various countries, the position that watermark distributes is not quite similar, and is divided into three kinds: the one, the fixed position watermark, promptly the position of watermark recovery on banknote fixed; The 2nd, the semi-fixed location watermark, promptly every group of mutual position of watermark recovery fixed, and each is organized on the nominal value of watermark and is continuous arrangement shape; The 3rd, the watermark of indefinite position is meant the full version watermark that is distributed in nominal value.The form of watermark has personage or animal picture, geometric figure and character pattern etc.It is high-visible, vivid true to nature that printing opacity is observed watermark, levels are rich, and stereoscopic sensation is strong, and good antifalse effect is arranged.Various countries' currency generally uses this anti-counterfeiting technology of watermark.

2. filament and color point: in paper pulp, mix special colored fiber silk during papermaking, or mix the sequin made from metal, plastics, what also have, is sprinkling upon filament on the paper not before the moulding at paper, makes paper be loaded with certain special material and plays anti-fake effect.Filament on the various banknotes, degree is revealed in its color, length, thickness, embedding and distributing position is had nothing in common with each other.As the U.S. dollar that the U.S. printed after nineteen twenty-eight, whole nominal value of reddish blue filament dispersed then only is distributed in the strip that nominal value hits exactly before this from top to bottom.The country that has also is added with radioelement on these materials of the color point of filament, visible fluorescence reflection under ultraviolet light.As banknotes such as Swiss franc, Danish Krone, ATS, Dutch guilders the fluorescent fiber silk is arranged all.

3. safety line: when copying paper, copy in the paper in the paper-making process, become the ingredient of paper money paper structure.The safety line material therefor develops into used opaque plastics line, photoluminescence line, micro track at present by the metal wire that adopts the earliest.The making of safety line needs higher paper technology, especially is interrupted and exposes safety line.This safety line is embedded in the paper for one section, and one section is exposed at paper, and the part of exposing is silvery white.As 20 pounds of paper money of sterling new edition denomination is to be changed into being interrupted by the metal safety line exposing safety line.

But however, still there is the lawless person to make a desperate move.Modern times make counterfeit money and often indiscriminately imitate to printing a complete set from paper, the lawless person has used high performance printing equipment, through complex processes such as offset printing, gravure and glue quadruplet seals, even can in paper, bury safety line underground, make the concave-convex sense of papery, printing ink of counterfeit money all very close with genuine piece, Hong Kong one counterfeit money group utilizes the equipment and the raw material in Japan and Taiwan as nineteen eighty-two, forges surplus ten yuan of denomination Renminbi 60,000, and 2,500,000 of U.S. dollars have been forged by Thailand one counterfeit money group in Bangkok.In recent years found the counterfeit money of fifty yuan and 100 yuan of face amounts in each province, China south, its papery is thin soft, the clear patterns degree is relatively poor, but very easy carelessness is taken under the low light level.The manufacturing technology of modern counterfeit money is very high, and its duplicity and harmfulness are also big more.

Summary of the invention

The objective of the invention is to overcome above-mentioned prior art defective, a kind of high reliability and safety anti-fake, banknote simple to operate, the method for anti-counterfeit of securities are provided.

The technical scheme that the present invention proposes is the method for anti-counterfeit of a kind of banknote, securities, it is characterized in that: contactless smart IC-card chip and coil are made miniature or ultra-thin card, also can not be packaged into card, in this contactless smart IC-card chip, write the particulars of banknote or securities, when making banknote or securities in miniature or ultrathin contactless smart IC-card or contactless smart IC-card chip and coil embedding paper money paper or the securities, become the ingredient of paper money paper, securities structure, to reach false proof way;

Described securities can be banker's bill, the letter of credit, check, stock, cashier's check.

Because in advance in contactless smart IC-card chip with the particulars of this banknote or securities, such as enciphered messages such as amount of money size, printing producer, the bank of issue, date of manufacture, banknote code, entry times, the enciphered message that reads the card stored by non-contact reader-writer during checking can be told truth from falsehood.At first, because between contactless smart IC-card and the read write line is the wireless frequency mode, but it is the parameter mode that adopts, and promptly each communication process has a variable function at random, thereby the external world wants that it will be extremely difficult coming the parameter of analytic system by radio receiver; Secondly, and any a slice non-contact type smart card and and any read write line without the mandate at hair fastener center, card and read write line all can not be worked, the card and the read write line that provide by the goods producer, after the specific authorisation card or other authorization mandates that must hold through the hair fastener center of national appointment, the use that just can put goods on the market, the information that so any disabled user wants to obtain in the card almost is impossible; Once more, because each contactless smart IC-card all has an independent card number, this card number is to form in the process of chip, be unique constant, also has certain memory headroom reading/writing document simultaneously, can utilize some support equipment that (as the present stored Bank Name or the code name of bank note) read and write and revised to some data, also some data can be made as and revise (as the amount of money of bank note, the date of production, printing producer, various information such as the time of making the product), and system region has the cryptographic algorithm verification in the card, therefore, it also almost is impossible forging card.So the false proof coefficient of banknote or securities increases greatly, and because read write line can read many banknote or the securities that embedded contactless smart IC-card chip and coil simultaneously, improved the concurrency of using, improved system works speed virtually, to bank, its work efficiency can improve undoubtedly greatly in the paper money paper working mechanism that needs points such as stock exchange are got huge quantity, because when checking, need many inspections hardly, currency examine only needs a bundle bundle to be put on the read write line, according to data volume that reads and reading/writing distance, read write line can be chosen different read-write chip, and demonstrates information such as quantity and counterfeit money quantity by computing machine or on read write line immediately.

Embodiment

The present invention is based on radio frequency identification (RFID) technology, this technology basic methods be:

Radio frequency identification (RFID) is a kind of contactless automatic identification technology, and it is by the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention.The RFID technology has waterproof, antimagnetic, high temperature resistant, long service life, read that distance is big, data can encrypt, store that data capacity is bigger, the canned data change waits advantage freely on the label.

The most basic rfid system is made up of three parts:

1. contact type intelligent card (radio-frequency card): form by coupling element and chip and built-in aerial, built-in aerial be used for and radio-frequency antenna between communicate.

2. read write line: the equipment that reads (in read-write card, can also write) label information.

3. antenna: between contact type intelligent card and read write line, transmit radiofrequency signal.

Read write line is connected with outer computer (host computer main system) by RS232 or communication interfaces such as RS485, bluetooth, carries out exchanges data.

The groundwork flow process of system is: read write line produces induction current by the radiofrequency signal of emitting antenna transmission certain frequency when radio-frequency card enters the emitting antenna perform region, radio-frequency card obtains energy and is activated; Radio-frequency card sends information such as self coding by blocking built-in transmitting antenna; System's receiving antenna receives the carrier signal of sending from radio-frequency card, be sent to read write line through the antenna adjustments device, read write line carries out the demodulation sign indicating number is judged this card according to logical operation legitimacy to the signal that receives, make corresponding processing and control at different settings, send the action of command signal control executing mechanism; Read write line also can carry out the demodulation sign indicating number to the signal that receives and deliver to the backstage main system then and carry out relevant treatment; Main system is judged the legitimacy of this card according to logical operation, makes corresponding processing and control at different settings, sends the action of command signal control executing mechanism.Also can judge the legitimacy of this card according to logical operation according to the independent read write line of designing requirement

In coupling scheme (inductance-electromagnetism), communication process (FDX, HDX, SEQ), snap into aspects such as the data transmission method (load-modulate, backscattering, higher hamonic wave) of read write line and frequency range from radio frequency, different non-contact transmission methods have basic difference, but all read write lines are on the principle of work and power, and all very similar on the design structure of decision thus, all read write lines all can be reduced to high frequency interface and two basic modules of control module.The high frequency interface comprises transmitter and receiver, and its function comprises: produce high-frequency emission power to start radio-frequency card and energy is provided; Modulate transmitting, be used for sending data to radio-frequency card; Receive also demodulation from the high-frequency signal of radio-frequency card.The high frequency Interface design of different radio frequency recognition system has some differences.

The function of the control module of read write line comprises: communicate with application systems software, and carry out the order that application systems software is sent; The communication process (MS master-slave principle) of control and radio-frequency card; The encoding and decoding of signal.Some special systems are carried out anti-collision algorithm in addition, the data that will transmit between radio-frequency card and read write line are carried out encryption and decryption, and carry out the additional functions such as authentication between radio-frequency card and read write line.

Fig. 1 is a contactless smart IC-card read-write system block diagram.Non-contact IC card consists predominantly of: chip, antenna and electric capacity; Read write line then generally is made up of single-chip microcomputer, intelligent object and antenna, and is furnished with the PORT COM with PC, LPT, and I/O mouths etc. are so that be applied to different fields; To the read write line energize, during the beginning read-write operation, the signal that read write line sends is made up of two parts stack: a part is a power supply signal, after this signal is received by clamping, supplies with chip operation with the transient energy of L/C generation of itself.Another part then is instruction and data-signal, and commander's chip is finished the reading of data, revised, storage etc., and return signal is given read write line.

The present invention can realize like this: contactless smart IC-card chip and coil are made miniature or ultra-thin card, also can not be packaged into card, in this contactless smart IC-card chip, write the particulars of banknote or securities, when making banknote or securities in miniature or ultrathin contactless smart IC-card or contactless smart IC-card chip and coil embedding paper money paper or the securities, become the ingredient of paper money paper, securities structure, to reach false proof way.

Because the cost of this technology own is higher relatively, if forge subsidiary false proof banknote or the securities that this technology is arranged, at first chip will be arranged, and this chip is the special chip of being supervised by the Ministry of Public Security or national financial supervision office (the People's Bank), the counterfeiter has no way of obtaining; If begin to copy from chip, its cost is big to be that small-scale, individualized production are inconceivable by main counterfeiter.So after such banknote or securities were general, most of fake producer was when making no public appearances.

The bank note that contains chip is read and write, is judged with the read write line that this bank note is supporting it can divide three kinds: a kind of be ground such as national treasury use not with the read write line of conventional false proof, it should possess the more ability that embeds chip bank note that reads while write is arranged.Possesses extraordinary reading/writing distance simultaneously, all passed through anti-dummy check warehouse-in because enter the bank note etc. of national treasury usually, here only as one count and chip false proof and stock's bank note is read and write modification some data wherein, as will going into the national treasury time, preserve the national treasury title and write, and the function that chip is activated or locks, as then locking of warehouse-in, then can not use without the usual channel outbound, then activate, can normally use through the usual channel outbound; Second kind, be that all functions of existing false proof counting instrument keep, and add a read-write card function thereon, as long as other false proof all confirmation the time, Card Reader is after collated correct, this bank note then gives by check, be judged to genuine note, otherwise, even other method for anti-counterfeit are all errorless, but read-write card is after check and correction is inconsistent with the check information of genuine notes, and then this bank note is judged to counterfeit money.Such read write line, the ability of read-write quantity must possess from one to the ability that reads while write hundreds of.The third then can be used as a kind of read write line that activates or lock chip and uses in transportation.As installing in armoured van or bank note transporting box, steal in this process as the people and rob.Handing-over without normal procedure, the read write line that then installs in containers such as armoured van or bank note transporting box locks wherein bank note automatically, then this bank note use that is under an embargo, the offender takes it and equals one in waste paper, can not consume anywhere, but also in use by complete monitoring, be easy to be found.

After having used this method, but the flow direction of every bank note of track of the whole process can be taken precautions against the activity of various money launderings and monitoring illegal private bank etc. effectively, reaches effectively to prevent to steal to plunder the bank or other financial institution's incidents generations, and the bank note of robbing for the robber carries out complete monitoring.

So, not only aspect false proof, and aspect currency management, contain the bank note of miniature contactless smart IC-card and have valency currency etc. can accomplish digital management; In a single day this method is applied, and not only plays an important role on false proof, E-Government, public safety, and more the management of informationized society is laid a good foundation.
