Description

Procedure for drafting and auditing securities

The present invention relates to a method for drafting and auditing securities.

To prevent counterfeiting, securities, such. As banknotes and others, printed on special printing machines and verse¬ hen hen, which usually differs from the design of other printed products, as securities have for the most part fine, more or less curved lines in many different colors. The colors used for this purpose may have special properties with regard to the reflection or absorption of infrared light. Other printing inks have special magnetic properties. In addition, the design is strongly influenced by the paper used, which can have security elements such as watermarks, security threads, holograms, kinegrams, etc., to further increase the security against counterfeiting.

Some or all of the appearance or design of the securities embossing features, such as the described security elements and the special printing, are detected and evaluated by suitable sensors, in particular for automatically detecting and / or checking the authenticity of the securities by means of processing machines , In this evaluation, however, problems may occur because the features of the processing machines due to the type of processing reasons can not or only incompletely detected by the sensors. Further problems may arise if similarities exist for all or some of the features of different types of securities, which do not allow or at least hinder accurate automatic recognition and / or verification of authenticity. It is therefore an object of the present invention to specify a method for drafting and checking securities, which makes it possible to optimize the features used for various securities and permits reliable identification and / or checking of the authenticity of the securities.

This object is achieved by the features of claim 1.

The invention is based on a method for the design and testing of securities, in particular banknotes, in which it is intended that a design for a security is designed by means of CAD, which has several features that the CAD data of the design of Wertpa Be provided, wherein the CAD data of the design of the security papers are checked for suitability of the features contained in the design for an automati¬ cal test.

The invention thus has the particular advantage that the method for the design and testing of securities ensures that correspondingly created designs of securities have features which are particularly well suited for automatic testing of the securities thus designed by means of processing machines. This ensures that the recognition of such securities and / or the verification of the authenticity of such securities can be carried out in a particularly reliable and secure manner.

In an advantageous embodiment, it is provided when reviewing the CAD data of the design of the security on suitability of the features contained in the design for an automatic test properties of the to take into account automatic testing of pre-processing machines and / or sensors.

In this way, it is ensured that constructive properties of the automatic testing undertaking processing machines and / or sensors, eg. For example, a transport system of the processing machine, which has transport belts that cover parts of the securities to be tested, or the resolution of the sensors that can not interfere with automatic testing.

In a further advantageous embodiment, it is envisaged that when checking the CAD data of the design of the security on the suitability of the features contained in the design for an automatic check properties of known securities are taken into account.

This offers, in particular, the advantage that newly designed securities do not contain features which are similarly constructed to features of known securities and / or are arranged similarly on the newly designed security. This avoids problems in examining and recognizing the newly designed securities, which can result from confusion with known securities if they have similar characteristics.

Further advantages of the present invention will become apparent from the dependent claims and the following description of a Ausführungs¬ form based on figures.

It shows: Figure 1 is a schematic representation of a basic structure of an arrangement for the design and examination of securities, and

Figure 2 is a schematic representation of a basic procedure of a draft of a security.

Figure 1 shows a schematic representation of a basic structure of an arrangement for the design and examination of securities, especially banknotes, but also checks, shares, tickets, etc.

The arrangement has a design device 50, the z. B. can be formed by a computer, the computer software for CAD (Computer Aided Design) performs. Software for CAD is to be understood on the computer executable programs, with the help of which designs of securities can be designed. In particular, it allows the use of CAD features that are used for the design of the design of the securities to design or to use within CAD stored, ready-made features. These features are incorporated into the design of securities to be redesigned using CAD. The term "features" should be understood to mean, in particular, security elements that enhance security against counterfeiting, such as watermarks, security threads, holograms, kinegrams, etc., but also the special printing used for the printing of securities.

As shown in FIG. 2, when designing a new security by means of the design device 50, a design of the security 61 is created by means of CAD. The CAD data of the design of the security produced in this case are then checked to see whether the features contained in the design of the security are suitable for a later automatic check 62. In particular, it is checked whether the CAD data of the design of the security contain features that cause problems in an automatic test, because the features can not be optimally evaluated by certain properties of the automatic testing machine tools and / or sensors , Such problems may arise, for example, when the processing machine has a transport system for transporting securities to be checked, which features completely or partially hidden, z. This is because, for example, the securities are held between transport belts for transport with the transport system. Other problems can be caused by the sensors used for the test, because they have a limited resolving power. As a result, features that are smaller than the resolution can not be reliably detected and evaluated for automatic testing.

For the verification of the CAD data, corresponding data from the automatic testing performing processing machines and / or sensors can be collected in a database, the z. B. in which the Ent- throw means 50 forming computer is stored. The data contained in the database is then used for the described review.

In addition to or instead of checking the properties of the automatic machines and / or sensors performing the automatic test, it may be provided that the CAD data of the design of the security are suitable for the features contained in the design for an automatic check with already existing securities to compare known properties. For the already known securities another database, z. In the computer constituting the design means 50, which contains the designs of the known securities. For this example, the CAD data of the known securities can be used, which show the nature and position of the features used within the known securities.

When reviewing the CAD data of the design of the newly designed security, overlaps or similarities with already known securities are identified by, for example: For example, the individual features of the design of the newly designed security can be compared with features from already known bank notes. For example, for a kinegram included in the design of the newly designed security, it can be checked whether there are kinegrams in already known securities which are similar in terms of pattern or size and / or which are attached to a similar position within known securities.

If such problems are found 63 in the review of the design of the newly created security, a warning 64 is issued to a person operating the design device 50. For this purpose, for example, the relevant feature can be identified and / or the nature of the problem can be indicated, for B. that a certain feature of transport belt is covered or a similar or the same feature is already used in a known security.

Likewise, it is possible that upon detection of problems 63, an alternative suggestion 64 is additionally generated as to how the identified problem can be avoided. For this purpose, for example, a position for the feature can be given, in which it is not covered by the transport belts or a modification of the feature similar to known features will be proposed.

If the proposed changes to the feature (s) are accepted, they are automatically incorporated into the design of the newly designed security depository. However, it can also be provided that the operating person makes deviating changes to the feature or features.

After a modification 61 of one or more features, provision may be made for a new check 62 to be made as to whether the changes made were sufficient to eliminate the identified problems of the features with respect to the suitability for the automatic test. This can be done until no more problems are detected.

If there is a design for the newly designed security in which the Über¬ examination no problematic for an automatic examination of the securities problematic features are recognized, the CAD data of the design of the newly designed security can be converted by the design device 50 into data 65, as used by the automatic testing vorhe- molding processing machines 10 and / or sensors 30 wer¬ the.

FIG. 1 shows a possible construction of a processing machine 10, with an input compartment 20 for the input of securities 21 to be processed, in which a singler 22 engages. The Vereinzeier 22 detects each one to be processed security 21 and transfers it to a transport system 23, which transports the single security through sensors 30. In the sensors 30, features of each individual banknote are detected, which are used, for example, for assessing the authenticity, the type (eg currency and denomination of banknotes), the state, etc. of the security are rele¬ vant. The features can be detected, for example, optically, electrically, magnetically, acoustically, mechanically, etc. For this purpose, detect the sensors 30, of which z. If, for example, only a single one can be arranged on one side of the transport system 23, the security or parts of the security with a certain resolution capacity results in a pixel size with which the security is scanned and recorded. From the detected pixels of the security, a sensor data set representing the security is formed by the sensors and / or a control device 40.

In the control device 40, the sensor data set is compared with reference data stored in the control device 40 in a memory 42, which detects the detection of genuine or counterfeit and / or counterfeit securities, the type of securities, the state of the

Securities and so on. As indicated in FIG. 1 by the dashed line, the reference data can originate from the design device 50 and be transmitted to the processing machine 10 via an interface 41, for example, and stored in the memory 42. The reference data corresponds to the above-described data generated by converting the CAD data of the design of the newly designed security.

On the basis of the check carried out by the control device 40 of the respective banknote, switches 24, 26 arranged in the transport system 23 are actuated, for For example, to deposit certain securities in an output tray 25, whereas other securities can be deposited in an output tray 27 or fed to a further processing 28 via the transport system 23. By means of an input / output device 43, the z. B. can be formed by a display and a keyboard, the processing machine 10 is controlled by the operator. For example, the above-described transfer of the reference data from the design device 50 to the memory 42 of the processing machine 10 may thus be initiated and controlled.

In order to be able to take account of effects occurring in the case of real securities, such as printing tolerances, aging, contamination, etc., it is possible to modify the CAD data or the reference data converted therefrom already in the design device 50 by simulation.

It is also possible to initiate and control further processing of the reference data by means of the input / output device 43. This is a certain number, z. B. 100 to 1000 pieces of securities of the newly designed security used and works with the processing machine 10.

A corresponding processing mode can be started, for example, by means of the input / output device 43 by the operator after the specific number of securities has been inserted into the input tray 20. The sensor data generated thereby by the sensors 30 for the number of securities are used for the modification of the reference data. Changes that result from the above-mentioned effects can be taken into account. The change in the reference data can be taken by the control device 40 of the processing machine 10. Likewise, it is possible to transmit the sensor data via the interface 41 to the design device 50 for further evaluation, in order to make corresponding changes there to the data resulting from the CAD data. wonnenen make reference data and the changed data again to the processing machine 10 to transfer.

It is obvious that the described reference data can also be used for any other processing machines and / or sensors that are identical in construction to the processing machine 10 and / or the sensors 30 for which the reference data were generated. Accordingly, it is also possible to derive other reference data from the CAD data, which are suitable for other types of processing machines and / or sensors.

It is also obvious that the above-described examination of the design of the security for suitability of the features contained in the design for an automatic test does not necessarily have to be carried out with CAD data. Rather, it is also possible to convert the CAD data beforehand into the data which are used by the automatic machines and / or sensors that perform the automatic checking, that is to say to convert the format to the sensor data or reference data described equivalent. It goes without saying that in this case the data required for the check, z. For example, the data of the known securities must be in the same format.
