Description

The invention relates to a method for verifying the authenticity of a value or security document and to a value or security document.

From the DE 10 2014 112 610 A1 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 recorded and compared with at least one security feature in an evaluation unit, which was also applied when the image was applied to produce 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 the authenticity of the data carrier is checked of the modified data record and the anonymized security feature. 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. Since the algorithm with which the data record is processed from the at least one document-specific feature and the modified data record is formed is not accessible, and the anonymized security feature consists of at least one document-specific feature that was modified with the algorithm, 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.

It is preferably provided that the result of the verification is output by the data processing device. This can be done, for example, by outputting information on a display of the data processing device. Alternatively, acoustic signals and / or optical signals, in particular using different colors, which describe the respective status “real” or “fake”, can occur.

Furthermore, the algorithm is preferably stored in the data processing device or in a computing device. In both cases, this algorithm is preferably stored in encrypted form, so that this algorithm cannot be read out. The storage of an algorithm in a computing device can have the advantage that increased security is made possible with regard to the storage and use of the data.

Furthermore, it is preferably provided that the computing device and the data processing device communicate with one another via a wireless and / or wired network. In particular, if the computing device is separate from the data processing device, increased security can be achieved.

Furthermore, it is preferably provided that the at least one data record, the at least one modified data record and / or information are exchanged with application software, in particular downloadable application software. Encrypted data transmission can preferably also be provided in order to enable secure data exchange.

The at least one document-specific feature on at least one data page of the data carrier is preferably optically provided by a camera and / or recorded electrically from a storage medium of a transponder module in the data carrier, preferably with a reader. Both can also take place at the same time. The reading device and / or a near-field communication device can advantageously be coupled to the data processing device or integrated in the data processing device.

Personalized features and / or production-specific features of the data carrier are preferably recorded as document-specific features. Any combination of personalized features and production-specific features is possible. This allows increased security in the design of the anonymized security feature.

The at least one personalized feature preferably includes data of the document owner, such as name, date of birth, biometric data of the document owner, a machine-readable zone on the data carrier, a portrait and / or encrypted information in the portrait. Individual or all features can be recorded by the data processing device. 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. Also, 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.

Furthermore, the at least one document-specific feature and / or the anonymized security feature can be stored in the transponder module and read from the storage medium of the transponder module in the data carrier by means of near field communication or through contact points on the storage medium.

When the value or security document is produced and the at least one personalized feature is applied to the data carrier, in particular to a data page of the data carrier, the at least one anonymized security feature is preferably applied. This anonymized security feature can be applied to the data carrier as a one-dimensional or multi-dimensional code separately from the further personalized features or other information. For example, a barcode or a QR code can be provided.

Alternatively and / or additionally, it can be provided that this anonymized security feature is integrated into a portrait or a picture of the document owner.

The anonymized security feature is preferably applied to the data page by an imaging process, in particular by printing, laser labeling or the like.

The object on which the invention is based is furthermore achieved by a value or security document which comprises a data carrier with at least one document-specific feature, in which at least one anonymized security feature is applied to the data carrier and / or is stored in a transponder module of the data carrier and the anonymous Security feature consists of a modified data record which is formed by a data record of the at least one document-specific feature and an algorithm. As a result, the value and / or security element includes an anonymized security feature applied and / or stored directly thereon, which is formed from document-specific features that are processed by means of an algorithm. This algorithm is encrypted and secret. When a data record is recorded from at least one document-specific feature and the algorithm is used, a modified data record is obtained which corresponds to that of the anonymized security feature and which cannot be traced due to the secret algorithm.

The at least one anonymized security feature is preferably applied to the data carrier as a one-dimensional or multidimensional code and / or in the personalized one embodied as an image Feature integrated and / or stored in the transponder module.

For verifying the authenticity of the value or security document 11 According to a first embodiment, the at least one document-specific feature 15th , 16 , 17th , 31 , 32 , 33 , 34 , 35 , 36 of the value or security document 11 recorded as this in 2 is shown schematically.

The ones on the disk 12 Applied or existing data or features are recorded by an optical device 23 detected. This optical device 23 , in particular a camera, can be a component of a data processing device 21st his. The data processing device 21st is designed as a mobile telecommunications device or as a tablet, for example. The data processing device 21st and the optical device 23 physically separated from each other Communicate with each other wirelessly or by cable. Through the optical device 23 becomes at least one document-specific characteristic 15th , 16 , 17th , 31 , 32 , 33 , 34 , 35 , 36 detected. This at least one recorded feature 15th , 16 , 17th , 31 , 32 , 33 , 34 , 35 , 36 is in the data processing device 21st into a data set 22nd converted to a computing device 25th is forwarded. A communication network is used for this 24 used by which the record 22nd can be transmitted wirelessly and / or wired. The computing device 25th can be provided in a central administrative facility or decentrally.

The acquisition of the at least one production-specific feature 15th , 16 , 17th , 31 , 32 , 33 , 34 , 35 , 36 which is stored electronically can also be carried out by near-field communication of the data transmission device 21st with the disk 12 done so that information from the transponder module 18th can be read out. Alternatively or additionally, electrical contacts can also be made on the transponder module 18th of the data carrier 12 applied to the in the transponder module 18th read out stored data and to the data processing device 21st transferred to. A combined transmission, i.e. an optical and electronic transmission, of at least one personalized feature to the data processing device can also be used 21st be provided.

A link between at least two document-specific features is preferably provided, in particular a link between the image 15th and other data of the document owner 16 , 17th such as the name, date of birth or data in the OCR zone that are recorded together. The data set is made from this data 22nd formed, which to the computing device 25th is forwarded. This can also ensure that an exchange of the image 15th to the data of the document owner or vice versa can be checked.

In the computing facility 25th a mathematical algorithm is stored. After receipt of the data set 22nd in the computing facility 25th becomes from the to the computing device 25th transmitted data record of the data carrier 12 additional information is generated with the mathematical algorithm. From the additional information and the data set 22nd becomes a modified data set 26th generated.

To verify the authenticity of the value or security document, 3 the one in the computing device 25th generated, modified data set 26th over the communication network 21st to the data processing device 21st transmitted. In the data processing device 21st becomes this modified record 26th with the anonymized security feature 19th compared.

The data processing device 21st can preferably simultaneously with the detection of the at least one document-specific feature 15th , 16 , 17th , 31 , 32 , 33 , 34 , 36 also the anonymized security feature 19th capture. This can also be done in a separate process step. This anonymized security feature 19th is recorded optically and in the data processing device 21st saved.

If by the data processing device 21st a match of the modified data set 26th with the anonymized security feature 19th is established, the authenticity of the value or security document is 11 in front. If there is no match by comparing the modified data set 26th and the anonymized security feature 19th is determined, there is manipulation.

The result of the verification can be shown in a display 27 the data processing device 21st are issued. This can be done by means of written information and / or an optical symbol. Alternatively or additionally, an acoustic signal and / or different colored displays that indicate the authenticity or the manipulation of the value or security document can also be output.

That on the disk 12 applied anonymous security feature 19th corresponds to the modified data set 26th . The modified data set 26th however, it cannot be directly related to the features applied and / or stored on the data carrier 12 be derived. Rather, it is separate from the disk 12 by the computing device 25th generating additional information and linking this additional information with the data record 22nd to the modified data set 26th required. There is thus a link between personal and / or individual data with an algorithm for the security feature 19th instead, which is anonymized on the data carrier 12 is upset. The security feature 19th cannot be directly recognized visually and / or in the picture 15th be integrated, but for example with a data processing device 21st verifiable.

In 4th is a schematic view of an alternative embodiment for verifying the authenticity of the value or security document 11 shown. The data processing device 21st captured optically by the camera 23 document-specific characteristics 15th , 16 , 17th , 31 , 32 , 33 , 34 , 36 . Alternatively, document-specific characteristics 15th , 16 , 17th , 31 , 32 , 34 , 35 , 36 also from the Transponder module 18th through the data facility 21st can be read out. A combination is also possible. This becomes a data set 22nd educated. The algorithm differs from the embodiment according to FIGS 2 and 3 in the data processing device 21st saved or deposited. By linking the at least one document-specific feature 15th , 16 , 17th , 31 , 32 , 33 , 34 , 35 , 36 with the algorithm is in the data processing device 21st the modified data set 26th generated. This modified data set 26th with the anonymized security feature 19th , which is also carried out by the data processing device 21st was recorded. If they match, the authenticity of the data carrier becomes 12 detected. Provided a comparison of the modified data set 26th by the data processing device 21st was determined based on the link with the algorithm and that of the data carrier 12 recorded anonymized security features 19th does not match, an indication of manipulation is output.
