Description

In the private, non-sovereign environment, personal data is required for various business transactions. Although it is possible to read these data from an identification document such as an identity card or passport electronically or machine. However, automated data entry is often not allowed by law due to existing or anticipated privacy laws.

For example, in the Federal Republic of Germany, personal data for private-sector purposes using the new electronic identity card (nPA) can only be entered automatically if an eID service (eID: electronic identification) is used. However, if the eID service is not available or if personal data is to be collected from foreign identification documents, the personal data must be collected manually.

However, the manual collection of personal data is prone to error, so it is necessary to review such data. This is often done by one person, but this is expensive and also buggy.

It is the object of the present invention to provide a concept for collecting data of an identification document, in which a check of the acquired data can be realized without a direct data comparison.

This object is solved by the features of the independent claims. Advantageous forms of further development are the subject of the description, the claims and the attached figures.

The invention is based on the finding that the above object can be achieved by an image comparison of an image of the identification document with an image of a document template, which electronically simulates the identification documents and is filled with the data of the identification document. The data is entered into a document template, which takes on the form of an identification document. The test image is generated by converting the filled-in document template into an image, in particular into an image file. In this way, the acquisition of data can be effected without a direct data comparison. In other words, only one image comparison takes place to check the acquired data. Electronic processing of the personal data is not performed according to one embodiment.

According to one aspect, the invention relates to a method for acquiring data of an identification document comprising: acquiring the data of the identification document, electronically inserting the acquired data of the identification document into an electronic document template associated with the identification document to obtain a comparison template, creating a test image from the comparison template, acquiring an optical image of the identification document by means of an image camera to obtain a document image, and electronically comparing the document image with the inspection image to check the acquisition of the data. According to one embodiment, the electronic comparison is carried out by means of an optical image comparison, in particular pattern comparison. In this way, a verification solution is provided in compliance with data protection regulations, which can also be integrated into the respective IT infrastructure.

According to one embodiment, the electronic comparison comprises optically comparing electronic image data of the test image and the document image. In this case, an optical image pattern recognition can be performed.

According to an embodiment, in the step of optically comparing, an image difference between the image of the identification document and the test image is displayed on a display.

According to one embodiment, the image difference is compared with a threshold value, wherein the image difference is displayed when a difference threshold value is exceeded. In this way, an image deviation and thus a data deviation can be detected and displayed. If the threshold value is undershot, either an image match and thus data match are indicated, or an indicator remains off.

According to one embodiment, the optical image of the identification document is present in an electronic image format, wherein the comparison template is converted into the electronic image format in order to obtain the test image. The electronic image format may be a digital image format such as JPEG format, PNG format or TIFF format.

According to one embodiment, the acquisition of the data is performed by means of an input interface, in particular by means of a keyboard.

According to one embodiment, in the electronic insertion step, the acquired data is electronically inserted into data fields of the electronic document template. This can For example, by means of an input mask or automatically supported.

According to one embodiment, the electronic insertion comprises automatically detecting a type of document based on the acquired data and selecting the document template associated with the type of document. Document types can be ID cards or passports.

According to one embodiment, the document template is a replica of the identification document. The replica can be digital and graphically emulate the external appearance of the identification document.

According to one aspect, the invention relates to a data acquisition device for acquiring data of an identification document, comprising: an input interface for acquiring the data of the identification document, an image camera for acquiring an optical image of the identification document to obtain a document image, and a processor which is configured insert the captured data of the identification document into an electronic document template associated with the identification document to obtain a comparison template, create a test image from the comparison template, and compare the document image with the test image to verify the acquisition of the data.

According to one embodiment, the processor is configured to compare electronic image data of the test image and of the document image or to perform an optical image comparison, in particular a pattern comparison, in order to compare the test image with the document image.

According to one embodiment, the data acquisition device is program-technically configured to perform the inventive method for acquiring data.
