In order to resolve the problem, a sensor is used first in the present invention to obtain the whole information of the paper money and then performing true-false determination by using the whole information in the prepared determining parts. Then one of the determining results is selected at one timing. Generally, the regions having received stumer and having refused real money are different due to the concluding methods. As a result, the problem can also be solved even the region having received stumer is approved, by changing the determination method at appropriate timing.
Description
Technical field
The surface information that the present invention relates to read securities, other article is judged the method and the device thereof of its true and false.
Background technology
It is more and more in vogue to utilize electronic money or credit card to carry out buying of article, but still in voguely at present utilizes bank note to carry out buying of article.This point is very clear and definite from the increase of emission of banknotes number.On the other hand, in recent years, also increase terrifically for the wrongful access of cash automatic processor, the number of packages that for example counterfeit money uses.And its method is also more and more ingenious.For example, forge the forgery certificate, counterfeit money of various kinds and it is put in the cash automatic processor, check forgery certificate, the counterfeit money accepted.Have and in next chance, forge forgery certificate, the counterfeit money of having been accepted on this basis in large quantities and put into the medium method of stealing money of cash automatic processor once more, more and more become problem.
In order to prevent such crime, more and more pay attention to the method for the reliability of raising cash automatic processor itself.For example, have bank note by the time make the collecting mode of working sensor by the bank note that in discriminating, uses of change prevent to forge certificate the method for collecting (for example, with reference to patent documentation 1: the spy opens flat 8-249512 communique).In this technology, its purpose is to prevent that the information of the specific part of forger's counterfeit note from coming show off to cross device.In addition, though in certificate storage encryption is arranged information and in automatic ticket checker, carry out suitably changing under the situation about reading corresponding the technology (for example, with reference to patent documentation 2: the spy opens flat 8-305904 communique) of enciphered message with it.
The method that has below illustrated is a feature with following 2: at the suitable moment (at random constantly), the information that (1) changes object reads the position, and (2) write enciphered message in object.But,, must consider following aspect for the judgement of the true and false that is applicable to the bank note that has been forged to heavens.(1) bank note that has been forged to heavens mostly is the front of having imitated bank note fine.Therefore, for example, even to read the possibility that the position has been forged at this place also high owing to change the information of object, so situation about can not deal with is a lot.In addition, under the situation of present bank note, because unequipped memory storage, so be difficult to write adaptively enciphered message.Moreover change information reads the position or makes moment of change enciphered message become the accuracy that in general way at random can differentiate low.
Summary of the invention
In order to solve such problem, in the present invention, utilize sensor to obtain the information of integral body of the scraps of paper of the securities of bank note etc., in a plurality of detection units that have been prepared, use this Global Information to carry out separately identification with different characteristics.Then, selecting of a plurality of result of determination sometime.
According to the present invention, for example, even exist the weakness part of certain decision procedure, i.e. existence to collect the determinating area of pseudo-certificate, by changing decision procedure in the suitable moment, even drop into the counterfeit money of having a mind to enter this determinating area and forging in large quantities, also can be refused.Moreover under the situation of so typical crime, the convict has lost the deciphering of characteristic of confidence judge to(for) the discriminating of the cash automatic processor of oneself considering, and the result has the effect of the number of packages that diminishes crime.

Embodiment
In the present invention, will make concrete form from the method that bank note etc. is obtained this physical message of Computer Processing of the sensor of various physical messages and microcomputer etc. with the code performance.
[embodiment 1]
On one side with reference to accompanying drawing, Yi Bian explain example of the present invention.At first, Fig. 3 shows the figure of the general survey of the cash automatic payment machine 31 of using an example of the present invention.In 31 framework, possesses CPU13.The 311st, the user puts into the deposit slot that cash is used, and the 312nd, be used for when not deposit and withdraw the keyboard of usefulness such as the necessary password of input or the amount of money, 313 and 314 is the bank card input port and the mouth of withdrawing the money.The 315th, be used for display device to user's display message.
Use Fig. 2 that basic principle of the present invention is described.In general, it generally is little value that the pseudo-certificate of detection unit is collected rate (collecting ratio in the auto levelizer mistakenly as true certificate) and true certificate reject rate (true certificate is judged to be pseudo-certificate or other scraps of paper shape and unaccepted ratio mistakenly), has not to be certain value of 0 on statistics.The example of several decision methods shown in Figure 2.21 of Fig. 2 shows the real distribution of the true certificate of the bank note of characteristic quantity the space that obtains from the information of scraps of paper integral body.But, because in general the real shape of this distribution is ignorant, so present situation is to use a large amount of samples to infer.22 of Fig. 2 has been dotted line shows the decision boundary of being inferred with certain deduction method 1.In general, the bias or the number of the sample of having collected are limited, so have zone 221 of having collected pseudo-certificate and the zone 222 of having refused true certificate.It is quite difficult that the criminal plans to make the pseudo-certificate that enters this zone 221 with general means.Therefore, it is more recently to seek the situation of the pseudo-certificate that enters this zone 221 with method a little by force.That is, prepare the pseudo-certificate of very various kind in advance, once it has been put into the pseudo-certificate of also checking the kind of collecting in the cash automatic processor.Secondly then, prepare the pseudo-certificate of the kind collected in large quantities, put in the cash automatic processor.Usually, Cancel Transaction thereafter, accept to be equivalent to the return of true certificate of the number of collecting of pseudo-certificate.As preventing such crime or eliminate the method for convict's energy, in the present invention, taked to prepare in advance the detection unit of a plurality of different qualities and selected method from the result of detection unit in certain suitable timing place.23 of Fig. 2 has been dotted line shows the decision boundary of inferring with certain deduction method 2.Similarly there are zone 231 of having collected pseudo-certificate and the zone 232 of having refused true certificate in this case.In addition, 24 of Fig. 2 be dotted line shows the decision boundary of having inferred with certain deduction method 3.Similarly there are zone 241 of having collected pseudo-certificate and the zone 242 of having refused true certificate in this case.In general, the zone of having collected pseudo-certificate usually has nothing in common with each other because of the different of deduction method that distribute with the zone of having refused true certificate.Thereby, for example, approved even collect the zone 221 of pseudo-certificate, in timing place of the input of accepting next, if change decision procedure (in the mode of the inside and outside judgement true and false of the dotted line that utilizes decision procedure to obtain) then also can be disposed counterfeit note utilization as described above.Underlapped from zone 221,231,241, this point knows better, in this application, and by use that the slightly different decision method of characteristic in the true certificate judgement is combined, the effect that can obtain.As the timing of the stored a plurality of modes of conversion,, then when transaction rarenesses such as next one when beginning transaction that has caused a large amount of refusals or night service, be decided to be each transaction and be with effectively if consider above-mentioned typical crime.
Secondly, use the flow process of processing of the flowchart text integral body of the block diagram of an example of the real structure of identification in this example that Fig. 1 is shown and Fig. 4.In the present invention, will be transported to discriminating portion, and utilize sensor part 111 in flow process 411, to obtain the physical message of the scraps of paper integral body of bank note etc. from the bank note that gathering mouthfuls 311 has been put into.At this, so-called physical message for example is a color image information etc.In addition, so-called bank note integral body, mean object that the specific subregion that has not been only will preestablish is decided to be information and obtains, the roughly whole of bank note be decided to be the object that information obtains, even so that also can over sight (OS) under the situation of only certain privileged site being carried out retrofit.This be because, if only that certain is specific subregion is decided to be object, then certainly can only be corresponding with specific counterfeit note.Thereafter, in characteristic quantity product process 416, according to the physical message that has been obtained generating feature amount in characteristic quantity generating unit 116.In characteristic quantity generating unit 116, generate the characteristic quantity that physical quantity is carried out the combined feature amount, for example showed in the composition of principal component analysis (PCA) etc.Usually, owing to need complicated processing, so generate these characteristic quantities with software processes.Secondly, in a plurality of detection units 112,113,114 of having prepared, use this characteristic quantity to carry out identification 412,413,414 respectively.Use on one side the characteristic quantity that has utilized the identical physical quantity that obtains from sensor 1, with different mode these identifications carried out software processes on one side.So, can carry out complicated processing easily, can possess various processing means simultaneously.In addition, for in the processing of hardware, because the cause of the burden of physics,, be good aspect reliability, the processing speed for the problem that breaks down etc.As mentioned above, in this application, will possess a plurality of determination processing this point about identification and be decided to be feature with different characteristics.
Whether enter with this characteristic quantity and to judge to distribute with the true certificate shown in the dotted line of the decision procedure 1,2,3 that has illustrated among Fig. 2 and 22,23,24 judge the true and false.For example, true certificate judged distribute and 22,23,24 be decided to be with each characteristic quantity group of having obtained from a plurality of true certificates as the zone of input by being determined with the stratiform neural network learning.At this moment, by preparing the different neural network of 3 neuron numbers or structure and learning, can obtain true certificate and judge distribution 22,23,24.Perhaps, also can make neuron number or structure identical, the initial value when learning by changing is obtained 3 different zones.In addition, also can not use 3 neural networks, and be to use different types of decision method to use the judgement of 1 neural network like that, as utilizing judgement, utilizing judgement according to the size of the true the shortest Europe of certificate sample distribution a few reason moral distance according to Mahalanobis (Mahalanobis) distance of true certificate sample distribution.Having, about such decision method, for example is the existing method of having put down in writing in Tokyo University's publication meeting " graphical analysis handbook " (publish day on January 17th, 1991, that high wood is done is male, Tianyang County writes " classification " 641 pages, " neural network " 190 pages for a long time down) again.And, utilize the selection signal that has carried out control by CPU13, in selection portion 115 (Fig. 4 415) one of a plurality of result of determination of selection.At this, the number of decision procedure is not limited to 3, so long as get final product more than or equal to 2.In addition, also can be based on a plurality of detection units of selecting signal to select in advance to prepare some, only carry out the processing in this detection unit.
Handle the bank note of being differentiated based on result of determination.That is, under the situation of true certificate,, be stored in money collecting box, on display device 315, show and drop into the amount of money, the processing of depositing or remit money as in order to deposit or to remit money and be counted by the bank note that dropped into.On the other hand, be judged to be under the situation that is not true certificate, in general be rejected and the gathering that turns back to Fig. 3 withdraws the money mouthfuls 311.Have, under the many situations of refusal number, the unusual alert message of display notification device conveys to the relevant personnel with information simultaneously on display device 315 again.
Have again, in the present embodiment, made and carried out whole 3 decision procedures structure of selection result afterwards, even but select 1 decision procedure and use its result, also can obtain identical result.Select signal to carry out the switching of door 122 with the timing of in by the selection timing generating unit of CPU13 control, being put down in writing as rule.As rule, for example can be decided to be in the next one transaction beginning that has caused a large amount of refusal that surpasses treating number.This is to have utilized the phenomenon that a large amount of refusals begins to take place under the situation of checking the counterfeit money of unaccepted kind not having narrated in the background technology after dropping into multiple a large amount of counterfeit moneys.So, set in advance the reference value of the rejection number in the given time, utilize with its relatively decide conversion timing.In addition, in the time of also can being each transaction beginning when the transaction at night is rare.This is because use counterfeit note to be target few night with the people mostly.Perhaps, also can specific rule be set especially, utilize random number to decide change regularly.If make carrying refusal information, Transaction Information in from the control signal of CPU13, just can realize regularly judging.
As the specific embodiment of above-mentioned rule, carried out a transaction during in accumulate result of determination from detection unit 11, in advance the number that is judged as refusal is within a certain period of time counted.Then, under the situation of this value, change to the decision method of transaction thereafter more than or equal to certain threshold value.In addition, in the 2nd rule, in advance the time of concluding the business is counted, under this is worth than the big situation of certain threshold value, perhaps based on the number of the securities of having judged within a certain period of time or the number of transaction, under this number situation littler, change to the decision method in the transaction thereafter than threshold value.Can implement these rules with above such program.
On the other hand, the selection mode signal generation 123 that the selection signal of which result of determination of indication selection takes place is a trigger pip with the control signal from CPU13, do not determine 1 in 3 result of determination with not selecting the same way as result randomly, or sequentially periodically select.Perhaps, also can be following method.Detect at each decision method in advance and judge the number of times that is adopted.Then, select the result of determination of this least number of times.By doing like this, do not have deflection ground and select specific result of determination.
Have again, prepared 3 kinds of modes in the present embodiment, but so long as multiple mode then also can be the mode of number in addition.In addition, in detection unit 11, also can be provided with and prepare a plurality of characteristic quantity generating units.That is, prepare a plurality of characteristic quantity generating units that generate different characteristic quantities from physical quantity of sensor.Can handle in the detection unit corresponding with each characteristic quantity generating unit in advance, also available selection circuit is selected characteristic quantity generating unit and detection unit respectively, judges the true and false with a plurality of characteristic quantities and multiple decision procedure.Then, from the result of determination of integral body, select a result.Utilize this structure, and then can carry out the different judgement of characteristic, improved effect.
In addition, the present invention is not limited to above-mentioned objective for implementation, is the securities of bank note etc., can use widely.As long as can obtain the information of the surface of object or shape etc., for example available structure identical with the present invention judged the true and false of name brands etc.
As above illustrated, according to the present invention, prepare the method for the identification of the multiple physical message of having used object integral body, select a kind of result of determination of method in the suitable moment.By doing like this, even for example known the weakness of certain decision method, owing to being other decision method, so have the effect of prior delinquency prevention at next time changing because of the counterfeit that has dropped into a plurality of kinds.The present invention can be applicable to the discriminating portion of automat of the securities of the processing bank note of cash automatic processor, automatic vending machine etc. etc., and is very big to the contribution of the further developing of industry, delinquency prevention in advance etc.
