Definitions

  • the invention relates to a method and a device for recognizing and / or testing of securities, the security being scanned in a predetermined grid is identified and checked for authenticity by a pattern comparison.
  • a simple device for checking banknotes is e.g. from US 5,607,040 known.
  • the banknote is drawn lengthways between two scanner units.
  • a bank note checking device which the Banknotes can also be recognized in an inclined position. Depending on the position of the banknote, they are added line by line scanned pixels in a certain way in a test data memory written so that the image of the banknote in the memory is always the normal position occupies. During the test, the image data with a predetermined pattern compared. With the specified algorithm for storing the test data, the Determination of the angle of the inclination and rotation of the image in the memory be avoided.
  • DE 195 17 194 A1 discloses a device for checking banknotes, in which the banknote is evenly distributed over the entire width using mirrors is illuminated. For example, two to four linear, parallel to each other arranged CCD arrays used, with a filter for a certain wavelength is arranged. For the evaluation the are in a Column values of the different CCD arrays combined. For note recognition is not only in the visible but also in the non-visible spectral range measured.
  • a method of checking the authenticity of money is e.g. in US 5,615,760.
  • a multi-dimensional space (which is determined by the measured parameters is established) it is determined whether a combination of parameter values within or lies outside an n-dimensional ellipsoid.
  • the object of the invention is to provide a method of the type mentioned at the outset, that reliable identification and authenticity check with relatively little Hardware effort enables.
  • the solution to the problem is defined by the features of claim 1.
  • the samples arranged in rows and columns of a representative Area with simple mathematical operations on a line vector pictured. An area that is a characteristic identifier is therefore reduced to a line in such a way that all samples are taken into account in terms of content are.
  • the sections are chosen in advance so that - in terms of area - the most of the surface of the security is taken into account. If not all cutouts This fact can have the same meaning for the authenticity of the security if necessary e.g. be taken into account by appropriate weighting.
  • a single contiguous section can suffice.
  • the sections are advantageously defined in such a way that more elements or samples per line are present as per column. If the data reduction is too strong, detection performance may be undesirably throttled.
  • the part of the image taken into account for the recognition and authenticity check should be a predetermined one minimum distance (e.g. 5 mm) from the edge of the security. Namely the edge is heavily worn on older banknotes and rather for analysis annoying as helpful.
  • Other calculations would also be possible.
  • Tailored to that recognizing image could e.g. certain line values added up and others subtracted so that the total value reflects a difference value.
  • Weighted averages are also generated (with the choice of weights based on those Can turn off image characteristics which are important or which are all recognizable Securities are common).
  • the hardware scanning area is advantageously larger than the dimension of the Securities.
  • a particularly simple and quick method to compensate for the angle dependency of the line vector according to the invention consists of several angular ranges are given with their own reference vectors.
  • the security is first determined in which angular range the security lies, to then simply access the corresponding reference.
  • the reference vectors are permanently stored in a memory.
  • the invention is based on a surface scanning of the security. It in principle, it does not matter what type of sensors are used to record the samples become. Optical scanning is common. Banknotes are used, for example, at a certain wavelength in the visible range of the spectrum.
  • the samples can also be difference values. For each sampling point e.g. the Subtracted intensity in red from that in green.
  • the method according to the invention can be implemented using known methods Units.
  • the processing is typically implemented in software.
  • Fig. 1 shows a banknote 1. This is completely scanned so that the edge software can be determined.
  • the scanning area 14 is larger than the one to be processed Banknote 1.
  • two cutouts 2.1, 2.2 are defined for banknote 1. Together, these cover the essential area of banknote 1 (e.g.> 50% of the area). You have e.g. the shape of elongated rectangles. A given one Edge area 3 of the banknote is deliberately not taken into account.
  • a scanning area (and thus each partial section thereof) can be understood as a matrix of samples.
  • the matrix of a section 2.1, 2.2 has a predetermined number n of columns S1, ..., Sn and one (in generally smaller) number m of lines Z1, ..., Zm.
  • the samples correspond e.g. the intensity of a particular color at the scanning location or the difference of different color intensities. Other combinations can also be used of physical measurements.
  • all samples a column summed up to a component of a row vector According to the existing number n of columns becomes a row vector ZV with n Components created.
  • One line vector results for each section 2.1, 2.2.
  • Each line vector ZV can then use a known pattern recognition method are analyzed (cf. the prior art mentioned at the beginning, e.g. US 5,615,760).
  • An important aspect of the invention is that the banknote is not currently being read must become. If the banknote is read in obliquely as shown in FIG. 3, then the angle ⁇ can be determined on the basis of the course of the edge 4. The cutout 5 is rotated accordingly with respect to the edge 4 of the banknote.
  • different angles ⁇ differ in advance Reference vectors generated and saved. Each reference vector applies to a specific one Angular range.
  • the bank note 6 is preferably transverse to the conveying direction with its longitudinal direction 7 past a reader 8.
  • the reader 8 has a length greater than that Banknote 6 is. The bank note 6 can thus be read in regardless of the position.
  • the reader e.g. an optical scanner unit
  • This can be designed so that it scanned the whole Can take picture. But it is also conceivable that the lines in the same necessary evaluation (detection of the edge and the angle, Generation of a running total of the columns).
  • the samples of the predetermined sections become passed on to the column summer 10. This generates the characteristic ones Row vectors ZV.
  • the Line vectors compared with the reference vectors. The result is e.g. a probability value for correct identification or for the authenticity of the banknote.
  • the angular position ⁇ is also extracted from the preprocessing unit 9. She will be in the selection circuit 12 used to store the relevant reference vector from the reference vector 13.1, ..., 13.4 for pattern recognition.
  • Reader 8 can by several different scanning units in different wavelength ranges be supplemented.
  • a unit for measuring capacitance be used in a predetermined grid.
  • the samples must thus do not necessarily correspond to optical pixels.
  • the invention proposes a method which Reliable and location-independent testing and detection with simple means of characteristic features.
