Patent number: 10950080Abstract: A method for examining a value document includes emitting ultrasonic pulses onto several locations on the value document. An echo pulse arises by reflection of at least a portion of a respective ultrasonic pulse at the value document. The echo pulses are received while forming echo values, and from the echo values at least a characteristic value is established as to the wrinkledness of the value document. As apparatus is provided for carrying out the method.Type: GrantFiled: January 25, 2017Date of Patent: March 16, 2021Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Jan Domke, Hans-Uwe Moosler, Klaus Thierauf

Patent number: 10049522Abstract: A means and method for checking a value document of at least one irregularity of at least one specified type, in which an ultrasound data record is captured which describes in locally resolved fashion at least one ultrasound property, a deviation data record is ascertained which describes in locally resolved fashion a deviation between the ultrasound data record and a model and is ascertained such that the deviation described thereby is minimal with respect to the model. The model comprises a model for the location dependence of the at least one ultrasound property of reference value documents of the specified value document type without irregularities of the at least one specified type, and using the deviation data record, it is checked whether an indication of an irregularity of the at least one type is present on the value document.Type: GrantFiled: September 11, 2014Date of Patent: August 14, 2018Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Johannes Feulner, Jan Domke

Patent number: 9792750Abstract: There is described a method for checking a value document of a specified type for the suspected presence of a forgery, in particular of a pieced-together forgery, wherein at least one ultrasonic property of the value document is captured in a spatially resolved manner so as to form location-dependent measuring data, wherein while employing the location-dependent measuring data it is checked whether there are present in a specified checking region of the value document two areal regions whose ultrasonic properties deviate from each other according to a specified difference criterion, and wherein there is formed an authenticity signal which represents the result of the check. Further, a corresponding checking device is described.Type: GrantFiled: December 19, 2012Date of Patent: October 17, 2017Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Jan Domke, Ingo Scholz

Patent number: 9683972Abstract: A method is for examining a sheet-shaped or card-shaped value document with a security feature having one or more cavities configured in the value document. The width of the cavity or cavities is in at least one respectively specified direction exceeding 10 ?m. Transmission values are established in a locally resolved manner for the transmission of ultrasound in a specified frequency range. In employing the transmission values, it is checked whether a specified number of transmission values is greater than a specified transmission threshold value.Type: GrantFiled: October 25, 2012Date of Patent: June 20, 2017Assignee: GIESECKE & DEVRIENT GMBHInventors: Jan Domke, Stefan Kokrhoun, Patrick Renner, Andre Gregarek

The measurement values for an ultrasound transmission of the value document are established in a spatially resolved manner, and it is checked while employing the measurement values whether for a specified number of locations in a specified checking region the ultrasound transmission according to a specified criterion is greater than a specified minimum ultrasound transmission that is characteristic of a specified portion, lying outside the checking region, of at least one value document of the specified value-document type.Type: GrantFiled: December 19, 2012Date of Patent: March 21, 2017Assignee: GIESECKE & DEVRIENT GMBHInventors: Jan Domke, Ingo Scholz

Patent number: 9582953Abstract: A method is described for checking a value document, wherein measuring values of the value document are detected in spatially resolved fashion. The measuring value detected in the respective measuring point is allocated to a node corresponding to this measuring point, and a two-dimensional network of nodes is formed therefrom. A network is formed from the two-dimensional network of the nodes and a source node and a sink node. By means of the maximally possible flow through the network, the value document is classified as suspected of forgery or not suspected of forgery. The maximally possible flow through the network is a measure for the degree of probability of the value document having a continuous object along a direction transverse to the direction of the network, said object indicating a manipulation of the value document, such as e.g. an adhesive strip or a separating line of a composed forgery.Type: GrantFiled: September 11, 2014Date of Patent: February 28, 2017Assignee: GIESECKE & DEVRIENT GMBHInventors: Johannes Feulner, Jan Domke, Norbert Holl
