摘要： A method for checking a value document of a specified value-document type has a window which has a foil region. 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.

摘要： A method includes checking a specified security feature of a value document which is present in a specified security-feature region of the value document. The security feature includes captured pixel data which describe spatially resolved with a specified optical spatial resolution, an optical image at least of the security-feature region of the value document, and there are captured ultrasound data which describe an ultrasonic property of the value document at least in the security-feature region, spatially resolved with a specified ultrasonic spatial resolution. The ultrasonic spatial resolution is lower than the optical spatial resolution. From the pixel data there are established first reduced-resolution pixel data for reduced-resolution pixels of the first reduced-resolution image which describe a reduced-resolution optical image at least of the security-feature region of the value document, whose optical spatial resolution corresponds to the ultrasonic spatial resolution.

摘要： 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.
