Patent number: 11823522Abstract: The present invention relates to a method, a sensor, a sensor unit and a bank-note processing machine for checking the completeness and/or authenticity of value documents. A value document comprises at least one machine-readable feature substance in at the least two locations. According to the method, the value document is excited at least locally at measuring locations. Furthermore, a feature intensity with respect to the machine-readable feature substance is captured location-resolved at several different locations of the value document. The location-based feature intensities are classified location-based with the help of a threshold value. Furthermore, location-based limits of a location distribution to be expected of the machine-readable feature substance are determined. Finally, a location-based distribution of the classified feature intensities is assessed.Type: GrantFiled: December 21, 2016Date of Patent: November 21, 2023Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Wolfgang Rauscher, Erich Kerst, Thomas Happ

Publication number: 20230274599Abstract: A sensor and a method for checking value documents are provided, each having a luminescent sheet-like substrate and a luminescent feature applied to a partial surface of the substrate, and to a value document processing apparatus. From the spectral vectors obtained for a plurality of measurement points and characterizing the intensity of the luminescent radiation of the value document detected in at least two spectral ranges, substrate intensity values and feature intensity values are determined, based on which a pure substrate mask is determined, which contains only those measurement points which reliably lie outside the feature. From the spectral vectors of the measurement points contained in the pure substrate mask, a mean substrate vector is determined, based on which corrected substrate intensity values and corrected feature intensity values and/or a spectral signature of the substrate and/or of the feature are or is, respectively, determined from the spectral vectors.Type: ApplicationFiled: July 8, 2021Publication date: August 31, 2023Inventors: Wolfgang RAUSCHER, Wolfgang DECKENBACH, Julia DANHOF, Thomas HAPP

Sensor and method for checking authenticity of valuable documents with a luminscent security feature
Patent number: 9989411Abstract: The invention relates to a method and a sensor for checking a value document which is moved relative to the sensor. The sensor is arranged to detect the luminescence of the value document in two different spectral regions at the same location of detection simultaneously. The two temporal intensity patterns of the first and second luminescences detected in different spectral regions are evaluated relative to each other. This eliminates the motion effects which distort the two intensity patterns in the same or at least very similar manner.Type: GrantFiled: December 18, 2013Date of Patent: June 5, 2018Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Wolfgang Deckenbach, Wolfgang Rauscher, Peter Kersten -

Patent number: 9418499Abstract: The invention relates to a method for checking value documents by which the similarity of the intensity spectrum of a value document to be checked to a reference spectrum can be tested. To check the similarity of the intensity spectrum recorded from the value document to be checked to the reference spectrum, not the recorded intensity spectrum itself is compared with the reference spectrum, but rather a corrected intensity spectrum adapted to the reference spectrum, which arises from the recorded intensity spectrum by a linear correction. The correction parameters of the linear correction function are ascertained by adapting the linearly corrected intensity spectrum to the reference spectrum. Through the adapting it is achieved that fluctuations of the recorded intensity spectrum that are due to measuring technology are compensated at least partly.Type: GrantFiled: April 4, 2012Date of Patent: August 16, 2016Assignee: GIESECKE & DEVRIENT GMBHInventors: Wolfgang Rauscher, Jorg Frankenberger
