Description

The present invention claims the priority of the Chinese Patent Application No. 20101020007, filed on Jun. 08, 2010, which is incorporated herein by reference. Technical field

The present invention relates to the field of information and image technology, and in particular, to a ticket identification method and apparatus. Background technique

As a special medium to replace the general equivalent logistics, cash banknotes represent the highest level of anti-counterfeiting technology. The anti-counterfeiting technologies commonly used in banknotes include: color changing inks, invisible printing, watermarks, security lines, magnetic numbers, infrared features, special banknote papers, etc., correspondingly, for different banknote anti-counterfeiting technologies, using color-changing ink detection, invisible Printing detection, watermark detection, security line detection, magnetic number detection, infrared feature detection, banknote paper detection, etc., complete the detection of specific security features on the banknote. In order to achieve a higher level of detection, and in order to cope with the breakthrough of some anti-counterfeiting technologies by counterfeit molecules, an organic combination of multiple detection methods is usually used to solve various banknotes or other ticket authentication encountered in reality. The problem.

However, due to the development of the technical level, the counterfeit molecules will gradually master the production process of the corresponding banknote anti-counterfeiting technology. Even if the counterfeit molecules target specific machines, it is possible to study a combination of various anti-counterfeiting technologies. On the one hand, it is necessary to deal with fake counterfeit banknotes such as counterfeit currency and altered currency (pointing to the national currency using scrapbooking, digging, uncovering, alteration, shifting, reprinting, etc., to make the national currency change form), another In terms of the means of authentication and technology, the level of false detection of genuine banknotes is as low as possible, because a large number of counterfeit instruments are still facing the processing of real money. This makes it necessary for the counterfeiting industry to balance the level of missed detection of counterfeit currency and the level of misrecognition of genuine banknotes during system design.

In the existing point counterfeiting machine, when the system starts to move the banknotes, the banknotes sequentially pass through various detection modules, such as magnetic number detection, security line detection, invisible printing detection, watermark detection, infrared feature detection, etc., each module is based on The obtained anti-counterfeiting feature of the module is used to judge the authenticity of the banknote, and finally the authenticity of the banknote is comprehensively determined by the judgment result of each module. Happening. Each module performs the detection of specific security features on the banknote in parallel. In addition, various patent solutions for banknote serial numbers have been proposed in the industry to complete the identification of the unique ID-banknote serial number on the banknote.

It should be noted that the application of the banknote serial number in the traditional number identification system is mainly for some practical needs of the bank, and the inquiry function for completing the related information for the serial number in a specific case is mainly for the normal case, the real banknote The serial number management content, such as the corresponding archive of ATM machine deposit number and storage person identity, is limited in the extreme lack of terminal equipment (even on ATM machines and sorting machines, there are few serial number identification modules). It is even more unique on the money counter) and the unmanageable problems caused by the huge sample size of the real banknotes.

The existing banknote authentication system, its performance is directly dependent on the performance of a single module or the superposition of multiple module performance. For example, the color-changing ink is the anti-counterfeiting feature point with the highest anti-counterfeiting intensity used in banknotes, and the magnetic detection is a security feature with relatively low anti-counterfeiting strength. Therefore, the system using the color-changing ink detection scheme has far better authentication effect. For systems using magnetic ink detection solutions. In addition, the superimposed system performance of multiple detection modules is better than the performance of a single detection module system. However, the higher the anti-counterfeiting detection scheme, the higher the system design and complexity, and the higher the stability and robustness of the true banknote detection. Whether using a single detection module or a stack of multiple modules, the balance between the detection capabilities of counterfeit notes and the robustness and stability of true banknote detection must be considered. It is impossible to pursue high-performance detection without neglecting the robustness and stability of a large number of genuine banknotes.

In the process of counterfeiting specific banknotes, the type of counterfeit currency for the first inspection of the counterfeit machine (and the same type of counterfeit currency has not been tested by the counterfeit machine) must rely on the banknote authentication system and technology designed by the existing system. That is, the detection is performed by a single or combined scheme of the banknote anti-counterfeiting detection technology; and the counterfeit currency of the banknote counterfeiting machine is not the first detection (the same type of counterfeit currency has been detected by the counterfeit machine), the existing system design scheme makes This type of problem is still handled in accordance with the counterfeit currency of the first test (the same type of counterfeit currency has not been tested by the money detector). It not only wastes the detection ability repeatedly, but also because the real banknotes have different degrees of wear and tear in circulation, which makes the corresponding detection point features weakened, which weakens the difference from the counterfeit banknotes, because it takes into account the stability and robustness of the real banknote detection. To a large extent, the ability of the first test (and the same type of counterfeit currency has not been detected by the money detector) is limited. SUMMARY OF THE INVENTION In view of the above, the technical problem to be solved by the present invention is to provide a ticket identification method and apparatus, which can quickly and accurately identify a fake ticket.

1 is a flow chart of a banknote identification method according to an embodiment of the present invention; and FIG. 2 is a schematic diagram of a banknote identification device according to an embodiment of the present invention. detailed description

Generally speaking, the choice and layout of paper money, patterns and even security points of national banknotes (or other tickets) are different, but any country's banknotes have their own unique ID at the beginning of design— Banknote (or other ticket) serial number (or called banknote number, banknote identification number, etc.). The number of digits in the serial number and the encoding rules are different and are strictly confidential for the country. Taking banknotes as an example, the serial numbers of any two real notes in the circulation field cannot be the same. The serial number of the counterfeit currency is obtained by random printing or by copying a portion of the genuine banknote serial number, and the counterfeit banknotes of the same batch basically have the same serial number. Therefore, in theory, according to the serial number printed on the banknote, the authenticity of a banknote can be discerned. However, due to the huge amount of real money flow and the lack of terminal number collection and processing capabilities, the purpose of identifying counterfeit banknotes has been achieved through the real banknote database. At present, it is not operational. However, according to the obtained counterfeit currency serial number, dynamically load and retrieve the counterfeit serial number database, reconstruct the entire The banknote counterfeiting system is achievable and operable.

In the existing banknote (or other ticket) authentication system, the number extraction, identification, storage system and counterfeit serial number database dynamic loading and retrieval system in the dotted line box are added to identify non-first detection (cum same species) The type of counterfeit currency has been tested by counterfeit instruments. In addition, by adding a comprehensive judgment system, the first test (and the same type of counterfeit currency has not been tested by the money detector) has the characteristics of counterfeit currency and non-first detection (the same type of counterfeit currency has been tested by the counterfeit machine) After the counterfeit currency feature is comprehensively judged, the final identification function of the system is completed.

A method for identifying a counterfeit banknote according to an embodiment of the present invention is to identify and identify the banknote (or other ticket) to be detected by identifying the number of the banknote (or other ticket), and combining the existing counterfeit currency ( Or other tickets) verification means to quickly and accurately identify counterfeit currency.

In order to make the principles, characteristics, and advantages of the present invention clearer, the following description will be made by taking banknote identification as an example in conjunction with a specific embodiment. The described banknote identification method and apparatus are equally applicable to other tickets.

Referring to FIG. 1 , a method for identifying a counterfeit banknote according to an embodiment of the present invention includes the following steps:

501, loading or updating a counterfeit number database;

After the system is started, it first checks whether the local counterfeit serial number database information is updated. If there is no update, the local counterfeit banknote serial number database is loaded; if the counterfeit banknote serial number database information is updated, the updated fake is loaded. Bank serial number database.

502. Extract a number of the banknote to be detected.

Setting a number collecting device at a predetermined portion on the banknote conveying passage according to the layout position of the banknote number; the method includes:

When the banknote to be inspected reaches the predetermined position, the number area image of the banknote is collected; the number area is an area where the number may appear;

The collected number area image is detected to determine whether the number area image contains the paper currency number; if the banknote number is included, the number is extracted from the image containing the banknote number.

For the implementation of the method for obtaining the banknote serial number, the technical solution for obtaining the banknote serial number described in the patent application No. 201 01 01 042 34. 503. Query the counterfeit currency number database to see if there is a number that is the same as the extracted banknote number; the banknote to be detected is a suspected currency.

504, using existing banknote detecting means to identify the banknote;

Specifically, the banknote to be detected is detected according to at least one of the following manners to further identify the authenticity of the banknote:

505, comprehensively judge the authenticity of the banknotes.

The judgment result in the step S04 can be combined with the judgment previously made by recognizing the banknote number, so that the authenticity of the banknote can be quickly and accurately identified.

It should be noted that, in step S01, the loading and updating of the counterfeit banknote serial number database has different levels of real-time requirements, so different real-time updating strategies can be designed according to actual needs to meet the actual needs of differentiation. .

Specifically, for an environment with high real-time requirements, a wired network or a 2G/3G mobile internet network may be utilized, and even a conditional place may utilize a wireless wif i network to complete loading and updating of the counterfeit bank serial number database;

For environments with low real-time requirements, you can use the serial port upgrade or U disk upgrade to complete the loading and updating of the counterfeit serial number database during routine maintenance of the terminal.

In view of the importance of the counterfeit serial number database, personalized and highly secure encryption measures are required for data loading/updating.

For the update of the counterfeit banknote serial number database, we can fully draw on all the existing equipment and capabilities, whether it is a counterfeit machine, a large machine or even a counterfeit banknote identification result that is judged by experts, can be uniformly summarized into the counterfeit banknote serial number. In the database. Moreover, in the actual banknote circulation process, the counterfeit banknote information found at any link should be confirmed and aggregated into the unified counterfeit banknote serial number database.

Referring to FIG. 2, an embodiment of the present invention further provides a bill identification device 200, including: a loading module 210, configured to load or update the counterfeit currency number database;

a number extraction module 220, configured to extract a number of the banknote to be detected; The identification module 230 is configured to query a pre-set counterfeit currency number database, and determine whether the number of the banknote to be detected is a counterfeit currency number; and the module determines that the to-be-detected banknote is a suspected currency.

The banknote identification device 200 further includes at least one of the following detection modules:

The color changing ink detecting module 240a is configured to detect the color changing ink of the banknote to identify the true color of the paper currency;

The invisible printing detection module 240b is configured to detect an invisible printing mark of the banknote to identify the true meaning of the banknote;

The watermark detecting module 240c is configured to detect a watermark of the banknote to identify the authenticity of the banknote; the security line detecting module 240d is configured to detect a security line of the banknote to identify the authenticity of the banknote;

a magnetic detecting module 240e, configured to detect a magnetic characteristic of the banknote to identify the authenticity of the banknote;

The infrared or ultraviolet characteristic detecting module 240f is configured to detect infrared or ultraviolet characteristics of the banknote to identify the trueness of the banknote.

The banknote identification device further includes:

The communication module 250 is configured to receive a new counterfeit currency number and provide it to the loading module 210.

The comprehensive judgment module 260 is configured to determine the authenticity of the banknote to be detected according to the result of the identification module 230 and each detection module 240.

In the counterfeit banknote identification technical solution provided by the embodiment of the present invention, the banknote serial number and the recognition result are stored and managed (storage problem, in the case of not using any compression means, the 10-digit serial number of one banknote of RMB needs 10 pieces Byte's storage capacity, converted to 1MByte of storage capacity can store about 100,000 banknote serial numbers, storage costs are lower). In this way, in the case of the second or even the Nth time of the same kind of problem, the identification of the banknote can be completed only by the dynamic loading and indexing of the counterfeit serial number database.

In addition, in the case where the banknote serial number is partially blurred, the number of remaining digits that can be identified can be matched, and the recognition level of 4艮 can be achieved as well, and the uniqueness of the serial number does not change much.

It is estimated that in the real environment, the first test (cum the same type of counterfeit currency has not been tested The proportion of counterfeit coins detected by the machine is not even 10% (very conservative figures, the actual data may be much less than 10%), mostly non-first detection (cum the same type of counterfeit currency used to be a counterfeit machine Counterfeit money detected). Through such a system design, 90% of the problems can be solved at one time, and for the remaining 10% of the problems, the corresponding technical means can be solved. According to this ratio, even if the counterfeit currency feature of the first test (and the same type of counterfeit currency has not been tested by the money detector) can not be solved 100%, only 50% is solved, correspondingly the new system structure The actual detection rate should be 90% x 100% + 10% χ 50% = 95%. The comparison and the original all the problems are attributed to the first test (the same type of counterfeit currency has not been tested by the counterfeit machine) The recognition rate of 50% of the counterfeit currency features is undoubtedly a huge improvement! Even if the counterfeit currency feature of the first test (and the same type of counterfeit currency has not been detected by the money detector) is solved by 90% (far below the current technical level), the recognition rate of the system under the system structure is 90% χ 100% + 10% χ 90% = 99%, while the traditional way is only 90%, system optimization is close to an order of magnitude!

Now, for the non-first detection (and the same type of counterfeit currency has been tested by the money detector), the resolution of the counterfeit currency detection rate of 100% is explained, because the recognition rate of the number is unlikely to reach 100%. The new national standard GB16999-200X defines the misidentification rate of the RMB number as follows: RMB serial number One of the 10-digit numbers is misidentified, which is regarded as a misunderstanding. The same algorithm and hardware, if the two digits are mistaken at the same time as the misunderstanding, the recognition rate is about to increase the squared number, and the estimation is based on the conservative thousandth rate. The probability of two simultaneous errors is one in a million, unlimited. Close to 100%. Even considering the fault tolerance of two digits, the impact on the uniqueness of the banknote serial number is minimal.

The following is an explanation of the identification of the altered currency in the counterfeit currency. The counterfeit molecules use a partial true partial splicing method to make the altered currency, which causes the security point detected by the machine to be a problem that the genuine banknote can not be effectively detected. It has always been an insurmountable problem of the existing money detector. problem. However, regardless of whether the serial number of the banknote serial number is genuine or counterfeit, it will not cause trouble to the counterfeit database system. Because once a real coin number is used as a change currency, then this real currency number naturally enters the management of the counterfeit currency database, and it is impossible for another real coin of the same number to affect the dynamic management of the counterfeit currency database.

The management of the counterfeit currency serial number database is dynamic. Even if the fraudulent elements can learn the database information of counterfeit currency management, it will not help the fraud, because they can only do it. It is to avoid the number of the existing counterfeit currency bank, choose a new number or copy the number of the real banknote, which only increases the counterfeit currency of the first test of the counterfeit machine (the same type of counterfeit currency has not been tested by the counterfeit machine) The sample size has little impact on the overall performance of the system. The most important thing is that for the counterfeit currency solution that is not the first test (the same type of counterfeit currency has been tested by the money detector), the source of the counterfeit currency serial number database is no longer limited to one or a certain type. Specific money detector machine. It is the result of testing all kinds of machines in the financial equipment industry and in the banking system, and even the results of the final testing through expert experience can be included in the counterfeit currency serial number database for non-first detection (cum) Counterfeit money of the same type of counterfeit currency that has been tested by a money detector. The counterfeit banknote identification technical solution provided by the invention introduces a dynamic loading and retrieval system of the counterfeit currency serial number database, which is very easy to solve the non-first detection which exists in reality in reality (the same type of counterfeit currency has been detected by the money detector machine) The validity and stability of the counterfeit currency are greatly improved, which greatly improves the counterfeit currency recognition level of the overall system, and does not affect the stability and robustness of the real banknote recognition. System performance has increased dramatically by one or even several orders of magnitude, while system costs have not increased significantly. The present invention can be implemented or used by those skilled in the art in light of the disclosed embodiments. Various modifications to these embodiments are obvious to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the scope and spirit of the invention. The above-mentioned embodiments are merely preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalents, improvements, etc., which are included in the spirit and principles of the present invention, should be included in Within the scope of protection of the present invention.
