摘要: 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.

摘要: 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.
