Definitions

  • the invention relates to a method for verifying the authenticity of a value or security document and to a value or security document.
  • a method for detecting manipulation of a value or security document is known. At least one image, which consists of a large number of pixels, is applied to a data carrier by means of a laser device. These applied image points are optically detected and compared with at least one security feature in an evaluation unit, which was also applied when the image was applied for the production of the data carrier. As soon as a laser structure deviating from the stored laser structure, which corresponds to the original image to be applied, is evaluated, a manipulation can be determined.
  • the invention is based on the object of creating a method for verifying the authenticity of a value or security document as well as a value or security document, whereby manipulations are further made more difficult or prevented.
  • This object is achieved by a method for verifying the authenticity of a value or security document, in which the at least one document-specific feature of the data carrier is recorded with a data processing device and a data record is formed from the at least one document-specific feature that contains at least one additional piece of information using an algorithm and a modified data record is generated together with the data record, and at least one anonymized security feature provided on the data carrier of the value or security document is recorded by the data processing device, which is formed from at least one document-specific feature and the algorithm, and in which by a comparison of the modified Dataset and the anonymized security feature, the authenticity of the data carrier is checked in a computing device separately from the data processing device.
  • This method can be used to create a comparison of at least one document-specific feature with at least one anonymized security feature, both of which are applied or present on the data carrier, the at least one document-specific feature being additionally modified by an algorithm for the comparison to verify authenticity only then to carry out the comparison with the anonymized security feature.
  • the replacement, alienation or exchange of at least one document-specific feature may not be optically visible in the event of manipulation, but the method for verifying authenticity can be used to check whether the at least one document-specific feature present on the data carrier corresponds to the anonymized security feature.
  • the comparison can be carried out and the manipulation to be established.
  • a manipulation of the anonymized security feature as well as the at least one document-specific feature can be determined if the modified data record formed from the at least one document-specific feature does not match the recorded data record of the anonymized security feature.
  • the result of the verification is output by the data processing device. This can for example, by outputting information in a display of the data processing device.
  • acoustic signals and / or optical signals in particular by means of different colors, which describe the respective status “real” or “fake”, can occur.
  • the computing device and the data processing device communicate with one another via a wireless and / or wired network.
  • a wireless and / or wired network In particular in the case of a preferably stationary computing device spatially separated from the data processing device, in particular in a building, increased security can be achieved.

  • Personalized features such as the name and / or the date of birth and / or biometric data of the document owner, can also be provided redundantly on the data carrier and are present both optically and electronically and are read out optically and electronically.
  • only a first part of the personalized features can be stored optically and a further part of the personalized features can only be stored electronically, so that both optically recorded and electronically read features are combined as a data set in the data processing device and forwarded to the computing device. From the combination of the recorded data, additional information is generated in the computing device by means of the algorithm in order to generate the modified data record. This can provide a further increase in security against forgery.
  • the at least one production-specific feature preferably includes data relating to the size of the data carrier, a zero point through two intersecting and adjacent edge lines of the data carrier, a center point between two eyes in an image of the document holder, a status of a background print on the data carrier and / or a position a letter, a number and / or a symbol on the data carrier.
  • the large number of these production-specific features which can be selected in any number, can in turn increase the security against forgery.
