Abstract

Embodiments provide devices (10), a substance measuring device (100), a method and a computer program for unambiguously assigning a measurement of a substance measuring device (100) to user-specific data of a subject of the substance measuring device (100). The user-specific data will be stored together with information about the measurement of the substance measuring device so that a subsequent change is recognizable.

Description

Embodiments relate to devices, a substance measuring device, a method and a computer program for uniquely assigning a measurement of a substance measuring device to user-specific data of a subject of the substance measuring device, in particular, but not exclusively, wherein the user-specific data are stored together with information about the measurement of the substance measuring device in that a subsequent change is recognizable.

Today's common breath alcohol analyzers are, in their majority, hand-held instruments that have a reduced user interface to reduce complexity and operator safety for the sampler. This means in practice that many devices have one to three button operation and a graphic display. These operating functions not only switch the devices on and off, but also perform more complex processes such as calibration or the encoded input of test reasons. A particular challenge may arise when personal data is to be entered into the device. This applies to both police and workplace-related measurements. A way out of the cumbersome use of two-button or three-button systems is the coupling of an external keyboard. Although this greatly simplifies the input, it is then immediately a significant increase in the total system volume as well as a departure from the compact hand-held measuring device that is actually kept. Using a touch screen solves the input problem with a screen keyboard, but it does not help with documentation or error prevention.

The US patent application US 2014/0335905 A1 shows a hand-held alcohol meter that is connected to a mobile device, such as a smartphone. On the mobile device can be displayed as a result of the measurement of breath alcohol. Furthermore, a camera of the mobile device can take and store a photo or a video of the subject during the measurement.

The European patent application EP 2 637 128 A1 shows different ways to enter text for a mobile device. In this case, for example, a keyboard or a text recognition via a camera can be used.

There is therefore a need to provide an improved concept for inputting user-specific data into a substance meter.

This need is reflected in the pending independent claims.

Exemplary embodiments are based on the recognition that it may be desirable to store user-specific data of a test person together with his test results in such a way that a subsequent change becomes recognizable and / or comprehensible. Thus, the user-specific data can be managed in a common closed record with the measurement result. The integrity of the data may be important and necessary for data security reasons. In the case of evidence-aware applications and devices in some places, the accuracy of the data, such as the date of birth and thus the age or gender of the subject or subjects, important because it has there influence on the assessment of the measured value. In the literature (compare, for example: Mußhoff F (2014) Blood alcohol determination - evidence security and equal treatment in criminal proceedings, Blutalkohol 51, 305-320), in some cases even the certainty of proof of breath alcohol measurements is questioned due to the possibility of incorrect entries.

At least some embodiments relate to a hand-held breath alcohol meter with at least one electronic module with digital electronics and digital memory, at least one alcohol sensor, at least one gas supply to the alcohol sensor (eg pump or bellows), a mouthpiece or a blower, a Messauswerte and processing algorithm, a camera and an image processing algorithm. For example, the camera takes a picture of the ID documents. As such documents are usually in question: passport, identity card, driver's license, corporate identity card or similar, which provide the important data for each application.

Exemplary embodiments therefore provide a device for unambiguously assigning a measurement of a substance measuring device to user-specific data of a subject of the substance measuring device. The user-specific data are stored together with information about the measurement of the substance measuring device that a subsequent change is recognizable.

Thus, for example, a subsequent manipulation or a subsequent falsification of measurement or user-specific data can be detected. This can improve the production of evidence-proof measurements that can be used in legal proceedings, for example.

In at least some embodiments, the substance measuring device is a Alcohol meter for measuring an alcohol content in the air. For example, the substance meter may be a hand-held substance meter. Especially with hand-held alcohol measuring devices, which are used in traffic controls for measuring an alcohol content in the breath, the evidence-safe assignment of user-specific data of a sample to his measurements may be relevant because these measurements may be used in court.

In some embodiments, the device includes a capture module for automated capture of the user-specific data. The user-specific data may include identity data. The apparatus may be configured to automatically capture at least parts of the identification data from an identity document via the detection module. This may allow faster and / or tamper-proof detection of user-specific data, such as badge data.

Exemplary embodiments furthermore provide a further device for unambiguously assigning a measurement of a substance measuring device to identification data of a subject of the measurement. The device further comprises a detection module for automated detection of at least part of the identification data. The device is designed to store the identification data together with information about the measurement of the substance measuring device. The following embodiments may relate to one or both devices.

In at least some embodiments, the user-specific data is based on image data. The acquisition module may be configured to receive the image data. For example, a large number of different documents with user-specific data of the subject can be automatically recorded. For example, the acquisition module may include a camera. The detection module can be designed to capture the ID data at least partially via the camera. For example, the camera may have a minimum focusing distance of less than 10cm. The camera, or the lens of the camera, for example, be designed so that so that sharp images at a small distance from the documents in question (see above) can be created and stored. This corresponds, e.g. the macro mode of conventional digital cameras. For example, the user-specific data can be recorded at close range, which can facilitate a simpler and error-free operation of the substance analyzer by a sampler and provide the identity document with as much of the image as possible.

Alternatively or additionally, the detection module may be configured to receive the user-specific data via a short-range radio communication transmission. This may allow the automated reading of the user-specific data, such as a passport document, a radio frequency identification (RFID) chip or a mobile device.

In at least some embodiments, the device further comprises a processing module. The processing module may be configured to perform image processing based on image data acquired by the detection module to recognize at least a portion of the identification data. For example, the processing module may be configured to perform a text recognition for recognizing the badge data based on the image data. This may allow, for example, the collection of ID data from a variety of different ID document formats. Alternatively or additionally, the device (such as the processing module) may be configured to automatically capture the user-specific data via a detection module from a coded optical identifier (such as a quick-response (QR) code or a barcode).

In at least some embodiments, the processing module is configured to recognize the badge data if the badge document has a format that is included in a plurality of formats of badge documents known to the processing module. For example, the processing document may associate recognized text of the badge document with data fields of the badge data.

In some embodiments, the apparatus is configured to store image data of the identification document together with recognized identification data of the identification document and the information about the measurement. This can further increase evidence security. For example, the device may be configured to store the image data as part of the user-specific information if the identification document has a format which is not included in the plurality of identification documents or if the device has not recognized all the identification data. For example, for a large number of documents, the automated recognition of the ID data can be supported, and in other cases, the storage of the pure image data can be used.

In at least some embodiments, the processing module is configured to detect edges of the identification document. The processing module may be configured to be based on the detected edges of the Identity document to provide evidence to a sampler of the substance meter about an orientation of the identification document for the detection of the ID data, such as a graphical output device or a light output module. The device may include, for example, a graphical output device. The device may be configured to output the image data via the graphical output device. Thus, for example, a check of the acquired image data and / or an aid with regard to the orientation of the identification document can be made possible.

In at least some embodiments, the graphical output device is a touch-sensitive screen. The apparatus may be configured to receive input from a sampler of the substance meter regarding a selection or restriction of a portion of the image data for acquiring the identification data via the touch-sensitive screen. For example, recognition of the badge data by the processing module may be facilitated by marking relevant data via the touch-sensitive screen. Alternatively or additionally, the device may be designed to provide a graphical representation of recognized text of the detected identification document to a sampler of the substance measuring device via the touch-sensitive screen. The apparatus may be configured to obtain an assignment of the recognized text to data fields of the ID data via the touch screen from the sampler. Thus, for example, in the case of identity documents whose format is not known to the processing module, a semi-automatic detection of the ID data can take place, which can avoid incorrect entry by the sampler or manipulation of the recorded ID data.

In at least some embodiments, the apparatus may further include a light output module for providing alignment assistance for aligning the identification document for detection by the detection module. For example, the light output module may be configured to project a grid structure or a detection frame onto the identification document. A first color of a light output of the light emitting module may indicate a presumably sufficiently good orientation of the identification document and a second color of the light output may indicate a presumably insufficiently good orientation of the identification document. Thus, for example, a sufficiently good alignment of the identification document can be made possible without the sampler having to check the quality of the recording via a graphical output device. For example, the processing module may be configured to determine at least one element of the group of an orientation of the identification document in the image data, a focus of the image data and a sharpness of the image data, and to control the light output module based on at least one element of the group. As a result, it can be determined, for example, whether a sufficiently good orientation of the identity document exists.

In at least some embodiments, the apparatus is configured to collect the user-specific data and the information about the measurement together if a time interval between a detection of the user-specific data and the measurement is less than a time threshold. Thus, it may possibly be possible to avoid assigning a measurement from one subject to another person's ID data.

In at least some embodiments, the apparatus is configured to form a first control character sequence over the measurement and a second control character sequence over the user-specific data. The apparatus may be configured to store the first control character sequence together with the user-specific data and the second control character sequence together with the information about the measurement. The user-specific data can be stored, for example, together with information about the measurement of the substance measuring device, that a subsequent change of the user-specific data, the information on the measurement of the substance measuring device or the assignment of the user-specific data to the measurement of the substance measuring device can be seen. For example, the user-specific data can be stored in a one-to-one correspondence with the information about the measurement of the substance measuring device. In other words, the control sequences can be linked by a one-to-one correspondence by being stored in the other data set. Thus, for example, a subsequent change of the user-specific data, the information about the measurement and / or the assignment of user-specific data and measurement can be traced.

Alternatively or additionally, the apparatus may be configured to form a common control character sequence over the measurement and over the user-specific data and to store the common control character sequence together with the information about the measurement and together with the user-specific data. Thus, a subsequent change of the user-specific data, the information about the measurement and / or the assignment of user-specific data and measurement can be detected at least.

In at least some embodiments, at least one of the group of the first control character sequence, the second control character sequence, and the common control character sequence may be based on an element of the group of a checksum, a hash value, a random value, and a key , Thus, subsequent changes can be detected by tracing the calculation of the control mark sequence and identifying differences to stored control sequences.

In some embodiments, the device may be configured to store the information about the measurement and / or the user-specific data based on a first key so that they can be read out with a second key stored only outside the substance measuring device. In some cases this can prevent subsequent manipulation of the data in the device.

In some embodiments, the device may further be configured to store further user-specific data of a sampler of the substance measuring device together with the user-specific data of the subject and the information about the measurement of the substance measuring device that a subsequent change is recognizable. This may allow, for example, an assignment of the measurement to a sampler, for example for purposes of proof.

In at least some embodiments, the user-specific data includes at least one member of the group of a subject's name, a subject's gender, a subject's age, a subject's date of birth, the subject's ID data, and a subject's identification number.

In at least some embodiments, the device further comprises a triggering device for triggering the detection module. The triggering device can be designed to be triggered by a sampler of the substance measuring device. For example, the acquisition module can be triggered when the sampler has aligned the identification document.

By way of example, the detection module can be designed such that it can be connected to the device or separated from the device by a sampler of the substance measuring device. This may allow a modular design of the device.

Embodiments also provide a substance meter with the device. For example, the substance meter may include fewer than five control buttons. The substance measuring device may be a hand-held substance measuring device, for example. The substance measuring device may be an alcohol measuring device for measuring an alcohol content in the respiratory air. A substance measuring device with such a device, which can be used, for example, in traffic controls for measuring an alcohol content in the respiratory air, can enable, in at least some embodiments, an evidence-safe assignment of user-specific data of a sample to its measurements.

Embodiments also provide a method for unambiguously assigning a measurement of a substance measuring device to user-specific data of a subject of the substance measuring device. The method includes obtaining the user-specific data of the subject of the substance meter. The method further includes obtaining information about the measurement of the substance meter. The method further comprises storing the user-specific data together with the information about the measurement of the substance-measuring device that a subsequent change is recognizable.

Exemplary embodiments furthermore provide a method for unambiguously assigning the measurement of the substance measuring device to identification data of the subject of the measurement. The method includes automated capture of at least a portion of the credential data via a capture module. The method further comprises obtaining the information about the measurement of the substance measuring device. The method further includes storing the badge data along with the information about the measurement of the blood glucose meter.

Another embodiment is also a digital storage medium that is machine or computer readable and that has electronically readable control signals that can cooperate with a programmable hardware component to perform one of the methods described above.

The device 10 This embodiment further comprises the detection module 12 for automatically capturing at least part of the identification data. The device 10 is configured to store the badge data along with information about the measurement of the blood glucose meter.

The following description of the device 10 and / or the substance measuring device 100 may be based on the embodiments of the device 10 and / or the substance measuring device 100 according to the 1a and 1b Respectively. The 1a and 1b further show the substance measuring device 100 with the device 10 ,

In at least some embodiments, the substance meter is 100 an alcohol meter for measuring an alcohol content in the breath, such as an alcohol meter, as it is used by the police in alcohol controls by drivers. The substance measuring device 100 may be a hand-held and / or mobile substance meter, for example, with dimensions where the longest edge is less than 20cm. The substance to be measured corresponds, for example, to a breath alcohol and / or anesthetics in the saliva of the subject. The substance measuring device 100 is therefore in at least some embodiments, a "mobile" breath alcohol meter or a meter for drug detection in saliva samples. For example, the substance measuring device can be operated by battery or accumulator. In at least some embodiments, the substance measuring device 100 less than five (or less than 4, less than 3) control buttons include, for example, an operating device for triggering the detection module, a touch-sensitive screen for monitoring a detection of the user-specific data, and / or a control button for turning on and off the substance measuring device.

In at least some embodiments, the unique association associates the subject's measurement with the user's specific data. For example, the information about the measurement of the subject can be stored with the user-specific data such that the user-specific data is uniquely assigned to the measurement and / or linked to it. For example, the device 10 be configured to store the user-specific data in a one-to-one association with the information about the measurement of the substance measuring device. The user-specific data can be stored together with information about the measurement of the substance measuring device, such that a subsequent change of the user-specific data, the information about the measurement of the substance measuring device or the assignment of the user-specific data to the measurement of the substance measuring device can be seen.

The device 10 may be configured to store the first control character sequence together with the user-specific data and the second control character sequence together with the information about the measurement. Thus, for example, the information about the measurement can be stored together with the second control character sequence in such a way that a change of the user-specific data associated with the information about the measurement becomes recognizable. For example, the second control character sequence may be a checksum or a discard value (also from the hash value) of the user-specific data. For example, by recalculating the checksum or hash value for the associated user-specific data, it can be detected whether it does not match the checksum or hash value stored along with the information about the measurement. Likewise, the user-specific data can be stored together with the first control sequence in such a way that a change in the information associated with the user-specific data about the measurement becomes recognizable. For example, the first control character sequence may be a checksum or a discard value (also from the hash value) of the information about the measurement. For example, by recalculating the checksum or hash value for the associated information about the measurement, it can be determined if it does not match the checksum or hash value stored along with the user-specific data. In some embodiments, the first control character sequence and the second Control character sequence also based on a device-specific code.

For example, the device 10 be configured to further generate the first control character sequence, the second control character sequence and / or the common control character sequence based on a device-specific code such that a calculation of the same values for the first control character sequence, the second control character sequence and / or the common control character sequence without this code not possible. The device 10 For example, it may be designed to sign or encrypt the first control-character sequence, the second control-character sequence and / or the common control-character sequence with the device-specific code. For example, the device-specific code may be a private key for which a public key outside the device is known. Alternatively or additionally, the device 10 be configured to store or encrypt the information about the measurement and / or the user-specific data based on a first key (such as the device-specific code / the private key) so that they with a second key stored only outside of the substance measuring device (such the public key) can be read or decrypted. For example, the device 10 be configured to sign or encrypt the user-specific data and the information about the measurement based on the device-specific code that changing the user-specific data and the information about the measurement outside the substance meter without this code is not possible.

In at least some embodiments, the device is 10 configured to (only) store the user-specific data and the information about the measurement together, if a time interval between a detection of the user-specific data and the measurement is less than a time threshold.

For example, the badge data may include one or more data fields for indications that are on at least some identity documents are identified. For example, the badge data may include one or more data fields containing information about at least one member of the group of a subject's name, a subject's gender, an age of the subject, a date of birth of the subject, an address of the subject, and a subject's identification number. For example, the identification data may relate to an identity document, such as a passport, identity card, driver's license, or a work card.

For this purpose, the detection module may be designed, for example, to communicate via a short-range radio communication or at least to receive data via a short-range radio communication. For example, the acquisition module 12 be configured to communicate via the Near Field Communication Protocol (NFC) or via the Radio Frequency Identification (RFID) protocol or to receive data, such as the identity document.

In some embodiments, this may be the acquisition module 12 be designed so that it by a sampler of the substance meter with the device 10 connected or from the device 10 can be separated. So the acquisition module 12 For example, be positively or positively connected via a plug connection with the substance measuring device. The acquisition module 12 can be about exposed contacts, via a connection cable or via a radio link with the device 10 get connected.

In at least some embodiments, the device comprises 10 , as further in 1b shown a processing module 14 , The processing module 14 may be configured to perform image processing based on the detection module 12 captured image data for recognizing at least a part of the badge data (based on a mapping of the badge document in the image data) to perform.

In at least some embodiments, the processing module is 14 perhaps configured to recognize the badge data if the badge document has a format comprised in a plurality of formats of badge documents associated with the processing module 14 are known. For example, the processing module 14 one A memory comprising, for the plurality of formats of identification documents, information about positioning of text fields on the identification documents and information about the data fields of the identification data corresponding to the text fields. For example, the memory may include information about the positioning of text fields and corresponding data fields for identity cards, driver's licenses and / or passports of one or more countries or communities of nations and / or for factory credentials. The processing module 14 For example, it may be configured to recognize which format of the plurality of forms of ID documents has an image of an ID document in the image data and to recognize the ID data based thereon. For example, the processing module 14 be formed to recognize text from at least one text box of the identity document and to save this text in a corresponding data field of the ID data. The processing module 14 For example, it may be configured to recognize text from at least one text field of the passport document and to store this text in a corresponding data field of the passport data without a sampler being able to change the text in the corresponding data field.

In this case, the identifier output by the light output module does not necessarily have to be evaluated by the processing module 14 be coupled. For example, the light-emitting module can be designed to project the light in the direction of the identification document, for example as a line, detection frame or grid pattern, independently of a current orientation of the identification document. In this case, for example, a color of the light output can be unchangeable. A user of the substance measuring device can use the emitted light to align the device and / or the identification document.

More details and aspects of the method are mentioned in connection with the concept or examples previously (eg 1a and 1b) have been described. The device 10 , the substance analyzer 100 and / or the method may include one or more additional optional features that correspond to one or more aspects of the proposed concept or examples as described before or below.

Embodiments provide a hand-held breath alcohol meter with extended data entry.

In at least some (basic) embodiments, the breath alcohol meter (such as the substance meter 100 ) with a camera (such as the acquisition module 12 ), which is triggered by a user (sampler) of the breath alcohol meter.

The user of the breath alcohol meter in this context is generally not the person who delivers the breath alcohol sample by blowing into the breath alcohol meter, but the person who asks the test person to deliver the breath sample, e.g. because it is authorized by legal requirements.

There are different possibilities to support the recording of the identification papers on the device side (for example by the acquisition module 12 ). In this case, for example, the user of the device, the digital image on the display (such as the graphical output device 16 ) preferably directly see the device so that he can select the desired image detail. Alternatively or additionally, the device can output a visual or audible message that the image acquisition is now useful.

In a first way of receiving the identification papers (such as the identification document), the camera image can be displayed on the display of the breath alcohol device and the sampler can align the device / camera so that an image of the identification papers can be created. Preferably, this can also be supported by an image recognition software (for example by the processing module 14 ), which, for example, allows the edges of the badges to be recognized and thus to align the sampler in aligning them along the edges of the image.

In a second way of receiving the identification papers, the camera image can not be displayed on the display of the breath alcohol device, which allows easier displays. Alignment support may now be provided by a light signal (analogous to laser pointer) emanating from the breath alcohol meter, such as via the light output module, which has an alignment aid, such as e.g. known from barcode scanners. This allows the sampler to be supported in the documentation without having to see the actual image of the document. In some embodiments, the sampler is supported in the documentation by using the aforementioned image recognition software, which releases the trigger only when the proper orientation and sharpness of the image of the ID document is recognized. For example, a frame representing the full image size can be projected onto the ID document.

The triggering of the camera for taking an image of the ID documents can be done, for example, either immediately before submitting the breath sample or immediately thereafter. In some embodiments, this may also be done before and after delivery of the breath alcohol sample to ensure that the breath alcohol sample is embedded in the documentary record of the identification documents.

In order to ensure immediacy between breath sampling and personal documentation, it may be possible to define a maximum time (such as the time threshold) that can elapse between the delivery of a breath sample (the measurement) and the documentation of the identification papers (the collection of user-specific data ). Furthermore, timestamps can be added to all images (user specific data) and measurements.

To represent a one-to-one correspondence between documentary footage and breath sample, a reciprocal sequence (such as the first control sequence and the second control sequence or common control sequence) that uniquely represents the data of the breath sample as well as the data of the identification documents taken for documentation may be clearly represented makes recognizable, first created and then added to each associated record mutually.

Such a sequence may be, for example, a checksum of the respective data values, a hash value of the data or a key generated according to a proprietary algorithm. Furthermore, this may be an alphanumeric random sequence.

The image data can then be stored (at least linked to the result of the breath alcohol measurement) in the memory of the measuring device.

Furthermore, it may ideally be possible to store the image data and the measurement data / results of the breath alcohol test in a common data record in the device. This may be e.g. Ideally, it should be a PDF ISO file format (according to the International Standardization Organization's PDF standard), which can enable the presentation and exchange of these files regardless of the device, its software, hardware or operating system.

The data can then be encrypted individually or ideally together by means of a key stored in the device such that decryption can only take place by means of a second key not stored by the device. Thus, for example, the requirement for privacy of the data listed in the identification document can be taken into account in relation to third parties.

If, after recording, the device recognizes that this recording is not valid, it can also be stored for documentation purposes (eg as part of the user-specific data). The user may now be prompted to take a new picture. The quality of the image may be decided based on the sharpness, the exposure, the contrast, and the orientation and OCR readability of the document.

In a preferred embodiment, the sampler is assisted in inputting personal data of the subject (the subject). This can limit the time frame of the entire review process and make processing safer. For this purpose, in this embodiment, the breath alcohol meter may be equipped, as in the general embodiment, with a camera which is triggered by a sampler of the breath alcohol meter. In this case, the user of the device, for example, see the digital image on the display of the device so that he can select the desired image detail. The display may be configured as a touch-sensitive display (touch screen) in this embodiment. The user of the Atemalkoholmessgerätes can now before or after a breath alcohol sample photograph the ID document of the person tested. The image data can be stored in the memory of the device as described above. For example, an algorithm can now be used in the device (for example in the processing module 14 ) Evaluate the image data such that characters are recognized. The necessary algorithms are known from the field of OCR (optical character recognition). By selecting the text sequences, the sampler can now select and need the personal data required for the application and transmit it to a digital form (for example for the data fields of the identification data) in the memory of the breath alcohol meter without changing it. This method can always be used if the format or type of the ID document is not predefined, but nevertheless more than just documentation is to be provided by a picture copy.

In a further preferred embodiment, a fully automated solution may be achievable if certain layout patterns are stored in the device (such as the majority of formats of identification documents). Based on this, an algorithm running in the breath alcohol meter (for example the processing module 14 ) either recognize the type of badge or the user can select the document present to him from a list. After determining the document type, the algorithm can now assign the texts recognized by OCR to specific data on the person being tested (the subject) and automatically transmit these to a digital form as in the previous case.

1. 1. Bei bekannten Ausweisdokumenten bzw. Ausweistemplates die Angaben zur getesteten Person einfach, schnell und fehlersicher übertragen, bzw. eingeben. (zweites bevorzugtes Ausführungsbeispiel - vollautomatische Ausführung)
2. 2. Bei unbekannten Ausweisdokumenten bzw. Ausweistemplates oder bei der Notwendigkeit zusätzlicher Angaben können diese durch die Teilautomatik (erstes. bevorzugtes Ausführungsbeispiel) leicht und fehlersicher übertragen werden.
3. 3. Bei nicht OCR - erkennbarer Schrift, weil z.B. die Schrift nicht hinterlegt ist, kann mindestens noch eine Dokumentation (etwa eine Speicherung der Bilddaten) erfolgen.

In practice, it may be particularly convenient to implement the aspects of the general embodiment and the two preferred embodiments in one device. This allows the user then

1. 1. In the case of known identification documents or identification templates, the details of the tested person can be simply, quickly and fail-safe transferred or entered. (second preferred embodiment - fully automatic execution)
2. 2. In the case of unknown identification documents or identification templates or if additional information is required, these can be easily and fail-safe transmitted by the semi-automatic (first preferred embodiment).
3. 3. In the case of non-OCR-recognizable writing, for example because the font is not stored, at least one documentation (such as a storage of the image data) can be made.

The problem presented can be solved for example by a breath alcohol meter (such as the substance meter 100 ) with integrated digital camera (such as the acquisition module 12 ) and an optical character recognition (OCR) algorithm (such as executed by the processing module 14 ).

The camera can be integrated (preferred) or mounted (retrofit option). The Graphic display of the measuring device may preferably be equipped with a touch screen.

At least some embodiments are based on the fact that the image data (or the user-specific data derived therefrom) and the measurement data are stored in a one-to-one correspondence with one another in order to avoid errors or permutations of the respective data. At least some embodiments are further based on the fact that a text recognition takes place from the image data and that the recognized text sequences without change in the "digital form" (the ID data) are taken over and the measurement data is uniquely assigned during storage. In at least some embodiments, furthermore, a previously determined and deposited layout pattern can be selected and the assignment of text contents to parts of the digital form can be carried out automatically depending on the selected layout pattern.

In some embodiments, a barcode may also be read in or communicated with an NFC / RFID chip, as e.g. is possible with the new German identity card.
