Definitions

  • the invention relates to the construction of security elements for documents and Devices for checking documents with such security elements and methods for the application of these security elements and devices.
  • the object of the invention is to eliminate the disadvantages of the prior art and in particular to complete the structure of security elements for documents with further security elements and to propose devices for testing such security elements and a new method of using security elements and devices which are essential to the counterfeiter make it difficult, if not impossible, to deduce the functioning of test methods and devices from the security elements to be tested, in order to then produce falsified documents which are so similar to the originals that they are not detected by test devices. It is also an object of the invention to propose safety elements and features or OVDs which have an optical diffraction effect and which can be checked quickly, independently of the person and with little effort and precisely.
  • the associated devices for testing security features are to be used both in high-speed document processing machines and in manual testing devices.
  • the task is solved by the following description of the invention.
  • the construction of security elements with a metallic reflective layer for documents to be checked provides for a new design that is not primarily based on visual inspection, but on test methods.
  • This design - hereinafter referred to as functional design - is the combination of electrically conductive and insulating structures of the same or different sizes, in the same or different planes to one another, with the same or different conductivities, and is produced from metallized structures and / or conductive inks or printing inks.
  • the functional design has a coding function in all distinguishable security elements and is therefore encrypted and can be checked.
  • the functional design can be a diffraction-optically effective security element or consist of electrically conductive colors or inks. If it is designed as a diffractive optically effective security element, it can match the optically, ie visually perceptible design and even support it in its optical design. Testable structures of metallizations and electrically conductive paints or inks in the form of lines, dots and Figures referred to. Such security elements are arranged on documents individually or in combination.
  • a security feature consists of at least one security element, preferably an accumulation of security elements of the same or different arrangement, size, color and / or conductivity.
  • diffraction-optically effective security elements are produced according to the invention from metallized structures instead of previous demetallization of individual structures.
  • metallized security elements are produced with a very close approximation to the desired metallized structure and steep edges to neighboring insulating structures. The steepness of these edges means that microstructures can be produced and checked.
  • the demetallized zones have been produced, for example by means of chemical etching processes, according to customary practice hitherto. As is known, these processes do not allow any steepness of the edges or an exact course of the desired structures.
  • the device for testing described security elements according to the invention has a capacitive scanner.
  • This scanner consists of a plurality of transmitting electrodes lying next to one another in one or more rows and a receiving electrode lying parallel to this series.
  • the scanner with small electrode areas has the advantage over sensors with large-area electrodes that there is less capacitive coupling between the individual electrodes.
  • the scanner is arranged in a document processing machine in such a way that the optical or mechanical sensors present in conventional document processing machines activate the test device according to the invention.
  • a sensor carrier is preferably used, which receives all sensors for testing. The distances between the sensors are minimized.
  • the device according to the invention has a pressure device which represents a very low resistance for the document.
  • This pressure device guides the document parallel to the transmitting and receiving electrodes or presses the document to be checked preferably onto the scanner. Furthermore, the axes of the transport rollers are connected to earth by means of sliding contacts. These additional shields and the pressure device guarantee repeatable test requirements with an even document spacing or contact and the functionality of the sensor is significantly improved.
  • the control of the individual transmitter electrodes with electrical energy is carried out with a time delay by means of control electronics with a switching frequency in the kHz range and beyond.
  • the main components of the control electronics in addition to the power supply are a multiplexer, an oscillator for providing the energy for the transmitting electrodes and an oscillator for controlling the multiplexer.
  • the energy of the respective controlled transmission electrode is capacitively coupled between this transmission and the reception electrode.
  • the signal curve at the receiving electrode is converted into a corresponding signal image.
  • the signal pattern depends on the metallized structure of the diffractive optical security element.
  • An evaluation electronics following the receiving electrode compares the signal image of the test document with corresponding reference signals.
  • the evaluation electronics essentially consist of a power supply, an amplifier, a demodulator, a comparator, a microprocessor with memory and filters to suppress external and interference signals.
  • reference signal images are stored in the memory and, depending on the security elements to be tested, are compared with the scanned signal image of the test document.
  • each electrically conductive security element is detected using the device according to the invention.
  • the comparison with the reference signal images provides a classifying signal for further processing. Accordingly, for example, a document recognized as a false certificate could be sorted out by stopping the checking device or redirecting the document transport route.
  • the sensor carrier is compactly connected to a circuit board that carries the control and evaluation electronics.
  • the other evaluation electronics correspond to those already described.
  • a further embodiment of the transmitting and receiving electrodes is characterized in that a plurality of transmitting and receiving electrodes are arranged next to one another and / or in series. Both the control and the reception of the signals are processed using the multiplex or demultiplex method.
  • these contain corresponding devices for transporting the document or the scanner, the function of which is similar to that of the transport devices in copiers, optical image feed scanners or fax machines.
  • a device is provided which defines the position of the capacitive scanner of the inventive test device in relation to the document by means of stop elements.
  • the device For the targeted testing of a defined number of security elements of a document, the device has a different number of transmitting or receiving electrodes lying next to one another. The greater the resolution achieved in this way, the more security elements and encodings with an increased level of difficulty in counterfeiting can be checked. As a result, simple hand-held devices, for example for everyday use, can be produced simply, easily handled and inexpensively, in which the presence of security features, for example a simple security thread, is checked. Devices with a higher resolution allow the testing of additional security elements, but without being able to recognize all the security elements. This is implemented using simple microprocessor software that is only sensitive to certain security features and is not public. A higher resolution with correspondingly designed software for the microcontroller allows all security features to be checked.
  • the invention also includes carrying out an image recognition and a status check of the documents.
  • image recognition via the coding is possible, namely an independent coding or as a supporting aid for sorting purposes, a coding for value level determination and a coding for authenticity determination.
  • an independent coding no further security element is present and the electrically conductive security element must be clearly identifiable, e.g. For example, the position on the document to minimize the incorrect rejection rate.
  • the coding then serves as a reference means in the event that an incorrect rejection has been detected.
  • a condition check is carried out with the aid of the test device according to the invention in the form that the conductivity of a security element allows conclusions to be drawn about the condition of the document, because experience has shown that a heavily used document also leads to wear on the electrically conductive structures and thus changes in the electrical conductivity.
  • the individual degrees of wear are classified using software. In this way, defined documents with a certain degree of wear can be sorted out. This degree of wear is expressed, for. B.
  • the security elements according to the invention are provided with codes which, in a mathematical relationship to one another - for example as a sum formation - result in a main code, which in turn contains a signal or code from the Simultaneous authenticity check of a metallic security thread and / or an equally synchronous check of an OVD determines the authenticity, the condition or the type of a certain document.
  • FIGS. 1 to 5 each show documents with security elements according to the invention, each of which contains a targeted electrical coding.

Very heavily worn paper will minimize the electrical conductivity very much.
