EP3074959B1 - Method for detecting data of an identification document - Google Patents

Description

In the private, non-sovereign environment, personal data is required for various business transactions. It is possible to electronically or mechanically read out this data from an identification document such as an identity card or passport. However, machine data collection is often not legally permitted due to existing or expected data protection regulations.

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

However, manual collection of personal data is error-prone, so that it is necessary to check data collected in this way. This is often carried out by one person, but this is time-consuming and also error-prone. The DE102009057360A1 discloses the preamble of main claim 1.

The identification document 101 includes, for example, a first data field 105 with personal data, which indicate a name of the person, for example, and a second data field 107 with personal data, which is arranged, for example, in the machine-readable zone.

The personal data of the identification document 101 are, for example, manually entered using an in 1 entered keyboard not shown. A document template 109 is assigned to the identification document 101 on the basis of the data entered. This assignment can take place, for example, by means of a verification program or verification software, with a document type of the identification document 101 being recognized on the basis of the data entered.

The document template 109 takes up the external appearance of the identification document 101, for example, and includes data fields 110 and 112, which correspond to the data fields 105 and 107.

The document template 109 or a selection of document templates can then be shown to a user on a display. After a confirmation or a selection of the document template 109, the optical detection or image recording of the identification document 101 can be prompted or initiated. However, the optical recording or image recording of the identification document 101 can also be prompted or initiated automatically after the automatic assignment of the document template 109 to the entered data.

In a subsequent step, the identification document 101 is optically recorded or read in, as a result of which a document image 111 with images 113 and 115 of the data fields 105 and 107 is created. The document image 111 can be present as a digital image file, for example. The document image 111 is then used, for example, for an image comparison.

A test image 117 with images 119 and 121 of the data fields 110 and 112 is created from the document template 109 in parallel or in any temporal sequence. The test image 117 can also be provided by a digital image file. The test image 117 looks like the personalized identification document 101, for example.

An optical image comparison between the document image 111 and the test image 117 then takes place, for example using the aforementioned verification software. Here, the software can visually compare the extent to which the images 111, 117 are congruent. Image differences can be visually displayed on a display. According to one embodiment, slight deviations between the document image 111 and the test image 117 can be tolerated up to a certain threshold value.

If an image difference is found, according to one embodiment, this is optically displayed or highlighted. in the in 1 In the exemplary embodiment shown, the optical difference can be caused, for example, by a deviation of a region 123 in the image 121 of the data field 107 compared to a region 125 in the image 115 present. The error can result, for example, from accidentally entering the letter "C" instead of the letter "D" when entering the data of the identification document 101. However, according to one embodiment, textual differences are not detected.

Here, for example, only the faulty regions can be displayed without detecting textual differences.
