Description

MOBILE VERIFICATION DEVICE FOR VERIFICATION OF TRAVEL DOCUMENTS

The invention relates to a mobile verification device for checking the authenticity of travel documents according to the features of claim 1.

In the course of increased security efforts, passports and ID cards are increasingly being equipped with security features that allow machine identification of the owner, prevent the misuse of such documents and increase their counterfeit security.

Such machine-readable IDs are hereinafter referred to by the term

Travel documents summarized. They have at least the standardized ICAO line, which is machine-readable with an OCR reading system.

Future machine-readable travel documents contain, according to ICAO standard ISO 9303, for example, in the personalization page or in the book cover, a storage element in the form of a radio chip, an RFID (Radio Frequency Identification) storage element, which can be read contactlessly via a transponder. According to ISO 14443A and B, the RFI D system used is a system at 13.56 MHz with an EPROM storage volume greater than 32 kbit, in particular greater than 72 kbit, with a plurality of biometric personal data, such as the face and / or fingerprints of up to ten Finger-rolled impressions and / or Iris¬ related data in JPEG format can be stored.

Verification systems installed or integrated in access control stations are subject to power consumption, contactless

Communication with a parent data network as well

Weight problems do not matter, because they are stationary on a fixed Weight problems do not play a significant role because they are stationary in a fixed place, but the situation for outpatient care is completely different, where these issues are a very important criterion.

With the invention, a mobile verification device is created, which takes into account the equipment of modern machine-readable travel documents and can be used by authorized persons in mobile use at border points in the entry and exit control and in the verification of persons at any location.

According to the invention, the verification device is provided for checking the authenticity of travel documents for mobile use, wherein mobile means that the device can be worn on the body and weighs less than 1000 g, in particular less than 700 g. It comprises an identification device for identifying an authorized user, a release device which releases the use of the mobile verification device for use on the basis of a signal of the identification device, an optical reading unit for reading image and / or alphanumeric information contained on the pages of the travel document, a data processing unit for Processing of the signals supplied by the optical reading unit according to a predetermined algorithm, a graphic display unit for displaying the read-out pictorial and / or alphanumeric data and the verification result determined by the data processing unit and a communication unit (20) for encrypted transmission of the read-out data and / or of the Verification result determined by the data processing unit to at least one central point and to receive relevant data from the at least one centra place over a communications network.

In a preferred embodiment of the invention, the mobile contains

Verification device, a contactless RFID reading unit, based on the determined by the optical reading unit alphanumeric data personal data of the travel document holder from a in Read out travel document contained RFID memory element. The RFID reading unit can be permanently installed in the verification device, but it can also be provided as a modular extension of a simpler device, which manages in the simple basic configuration without RFID.

For example, the read module will only perform a read if certain given ICAO data has been read on the personalization page and these match certain data of the electronic memory of the RFID system. Through the use of special cryptographic measures, modifications and forgeries of the electronically stored data as well as the replica are extremely difficult; A possible misuse can be quickly visualized and localized by means of appropriate security measures during read-out.

Preferably, the verification device comprises a mobile telephone and / or PDA (personal digital assistant) and a modulatable, in particular pulse-operated illumination device and as an optical reading unit, a camera module, with a personalization page and / or machine-readable characters are recorded, which are then subjected to the verification , On the screen of the mobile phone / PDA, for example, the image from the memory of the RFID element and / or the scanned or taken with the camera module image of the travel document holder is displayed. Two or three of these images are displayed side by side for visual comparison or superimposed to detect any deviations. In addition, these images can be transmitted immediately to a competent body via a communications and data network. It is particularly advantageous for the graphical display unit, data processing unit and communication unit to be formed by a mobile telephone in which these functional units are already combined.

The RFI D reader module is preferably integrated in the mobile phone. It can be on the mobile phone but also an RFI D reader module as an adapter or

Replacement part be appropriate. It is complemented by a security-enhanced wireless communication module with the Communication to an external data network is possible. Depending on the field of application, the wireless communication module has a range of a maximum of 100 m, in particular a maximum of 30 m, in particular a maximum of 10 m. It can be designed as a blue-tooth, wireless LAN or IR module. It is particularly advantageous if the wireless communication module is constructed on the basis of a mobile telephone module and provided with encryption devices for secure data transmission via public mobile radio networks or the police radio network or via the digital radio.

The optical reading unit preferably comprises an OCR module for reading the standardized ICAO line in passports and ID cards, for example a small field scanner of at least the length and / or height of an ICAO line of a passport. In further embodiments, the optical reading unit includes a scanner constructed in line form raster elements, preferably based on a contact image sensor line (CIS) with CMOS or CCD elements, with which very small-sized scanners can be realized. Optionally, a relative movement between device parts and the passport will be required to scan the ICAO line, which can be done in principle in either direction, but for cost reasons and because of the space requirements preferably the shorter route is selected. It is particularly advantageous if the optical reading unit of the mobile verification device is formed by the camera module of a mobile communication device, in particular a mobile telephone or PDA.

Mobile phones and PDAs with integrated camera module in the form of matrix-type CCD or CMOS elements belong to the state of the art. At the moment, components with up to 3 million pixels and color resolution are already available, which can also be used for verification tasks. Mobile phones and PDAs with camera systems usually operate without a flash unit, but in comparison with digital cameras already have a relatively high-security wireless data transmission device in the form of a mobile radio network. In this embodiment, thus can be a low-cost mobile phone or a low-cost PDA with Camera module not only for recording the personalization of travel documents but also with a suitable lighting device for recognizing coded or hidden information use.

Preferably, the optical reading unit is provided with a lighting device comprising modulatable, in particular pulsable light sources, in particular LEDs and / or laser diodes. Since, on the one hand, LED elements in the UV and in the IR range are available at very low cost and with high power, in particular high pulse power, and on the other hand flash lamps also have a relatively high proportion of non-visible light, the integration of such illumination systems into pigments of printing inks contained security elements, eg Stokes or Antistokes security elements of the printed image are excited. With appropriate timing then the respective response signals are recorded, which may be in the visible but also in the non-visible wavelength range, for example. In the NIR range. The matrix-type photoelements of camera modules of modern mobile phones as well as the sensors of a grid-like structure are based entirely on circuits on silicon substrates; their wavelength sensitivity extends from the UV to the NIR range at about 1100 nm. Depending on the design of the security elements, it is possible to use a broadband or several narrowband emissions. However, instead of or additionally, the temporal behavior of the security element can be used for verification. Since conventional Stokes and Antistokes elements have a relatively different attack and decay behavior, this temporal behavior can be used by excitation with a temporally correspondingly modulated or pulsed light system with advantage for authenticity verification.

In a specific embodiment of the invention, the transparency of printing inks and opaque plastic films for the NIR region can be used for the authenticity verification of hidden information. For example. For example, NIR-active pigments can be incorporated below a print layer or below an opaque film. These security elements can then be activated by means of NIR irradiation. The response signal is by means of integrated camera detected. It can then be forwarded wirelessly to the superordinate data processing system and evaluated or pre-evaluated in the device.

According to the invention, the data processing unit of the verification device can be designed so that it autonomously and off-line verifies the travel documents without having to communicate with an external data network, but it can also be designed so that the verification of the travel documents on-line or partially on-line in communication with an external data network. In particular, the verification of the travel documents is first carried out off-line, without communication with an external data network, wherein in the presence of an unclear Verifikationsergebnisses for a limited time on¬ line operation is switched.

Preferably, in the verification device according to the invention, a device is provided which receives verification-relevant data via the communication device at predetermined intervals and carries out a data comparison. This can in particular also take place by means of a docking station with which the mobile verification device can be connected at least temporarily. The docking station in turn receives verification-relevant data at predetermined intervals and carries out the data synchronization. In this way, the mobile verification device is constantly kept up to date with relevant information, and can, for example, verify the data of the travel document in comparison with an updated wanted list.

Preferably, the verification device is equipped with a biometric sensor, which can be realized, for example, by the camera module. With such a biometric sensor, an iris scan can be performed, wherein the iris data are supplied to the verification process. It is particularly advantageous if the biometric sensor is designed as a fingerprint sensor. The data processing device is here for comparison and verification of a mobile recorded biometric feature with a on the travel document or Identity card, in particular designed in an RFID chip stored biometric feature. Alternatively or additionally, the verification of a biometric feature recorded on the move can also be carried out on-line via the communication device at a central location. In one development of the invention, the data processing device is designed for comparison and verification of a facial image recorded on the move with a face image stored on the travel document or identity card, in particular in an RFID chip.

The biometric sensor of the verification device according to the invention can advantageously be used in a number of functions, namely to enable the device for the authorized user, to encrypt and secure the data transmission via the communication network and to the aforementioned verification.

In a development of the invention, a camera module is provided with which the current facial image of the document holder can be picked up from two different viewing angles. This allows a visual comparison to be made with much greater certainty. For this purpose, the verification device can be equipped in particular with two camera modules.

In order to compensate for possible different magnifications and scale distortions when taking pictures in mobile use, in the case of camera modules which are designed to receive the entire personalization page of the travel document, a distortion correction on the basis of the ICAO line is provided in the data processing device.

To prevent unauthorized operation or unauthorized use, the operator of a mobile verification device must be present

Identify commissioning. This can be done according to the invention not only via a biometric sensor but also in that the

User with an electronic identification element logs, so for example. With a smart card, a USB token or with a contactless RFID element. Further features and advantages of the invention will become apparent from the following description of exemplary embodiments.

Figure 1 shows a first embodiment of a mobile verification device 1 based on a contact image sensor (CIS) with about half the size of a notebook. The optical reading unit 22 uses a grid-shaped CIS line 13, in which lighting elements, optics and sensors are integrated. The CIS line is thereby moved with a length of about 86 mm in the direction of the long side of a personalization page 3 of a machine-readable travel document 2. Alternatively, the relative movement between CIS line 13 and travel document 2 can also be realized in that the CIS line 13 is arranged stationary and the personalization page 3 is pulled past it by hand.

In the example shown, a transparent support plate 12, for example made of glass, serves as a support for the personalization side 3 and for the exact guidance of the CIS sensor.

Sensors 13. The machine-readable travel document 2 is doing with the

Personalisierseite 3 together with one of the cover lid in a slot-like receiving opening 11 of the mobile verification device 1 is pushed. The book seam or fold 8 comes to lie on the front edge of the receiving opening 11, so that the remaining passport pages. 9 and the second cover left outside. Preferably, the receiving opening 11 is rounded at the front to facilitate the insertion of the travel document. In addition, a slight springing is provided, with the Personalisierseite 3 is pressed against the support plate 12.

The electronics 15 for driving and signal processing for the operation of the CIS line 13 is located on a circuit board 14 in the housing of the optical reader 22. The CIS line 13 is constructed on the basis of CMOS and LED lighting elements, the latter for illumination the personalization page 3 with white light or RGB light, or UV and / or NIR light are formed. The CMOS-CI S lines can also be provided with selective filters which limit the sensitivity of the sensors to predetermined wavelength ranges. The sensitivity limit in the NIR wavelength range is limited by the use of silicon for the CMOS circuit and is usually 1050 nm.

On the optical reading device 22, a reading module 16 (RFID module) for reading a transponder contained in the travel document or radio chips 25 (RFID element) and a mobile communication device 17 with a display 18 and a keyboard 19 is arranged. These device parts can communicate with each other via appropriate interfaces, such as USB, or wirelessly.

Instead of such a modularly arranged RFID module 16 may also be an RFID pen with, for example, blue-tooth transmission module for the input of RFID data can be used. In the example shown, the arrangement is made such that an RFID radio chip, which is integrated in the personalization page 3 or in the travel document binding, can be read out simply and reliably and the entire reading system is accommodated in a compact and tightly limited manner. In principle, however, the RFID reader 16 can also be integrated into the communication device 17.

In Figure 1, a wireless communication module 20 is further schematically illustrated. It corresponds in its function to a standard mobile phone or the police radio and serves the communication in a suitably equipped radio network. It can also be designed as a Bluetooth, W-LAN or IR module that meets the security requirements and requirements required for such a system, and can be operated online, offline or partially online.

FIG. 2 shows the optical reading part 22 of the mobile verification unit with a contact image sensor line (CIS) rotated by 90 °. The length of the CIS line is approximately 127 mm in this case and is moved over the shorter dimension of the personalization page 3 of a passport 2. The verification scanner 22 again comprises, in a small portable housing slightly larger than a travel document and several centimeters thick, on the front side a receiving opening 11 for at least the travel document cover and the personalization page 3, a transparent plate 12 to which the travel document is pressed is a CIS line and a circuit board 14 with the appropriate electronics.

Fig. 3 shows schematically an enlarged detail of the optical reading unit. The rice document 2 lies with the personalization page 3 on a transparent plate 12 immediately below the contact image sensor line 13 is arranged, which includes a CMOS sensor line 29, which in turn is arranged on a printed circuit board 28. Such sensor lines typically have a resolution of a few hundred dpi up to about 600 dpi. The mapping of the personalization page 3 is carried out by line by line scanning due to a linear relative movement between CIS line 13 and template to be scanned by means of a rod-lens array 30, which consists of rod-shaped optical fibers, which are arranged in a cell shape with a certain filling factor. The illumination is effected by LED rows (31, 32, 33) which are arranged on the same circuit board as the sensors 29. Alternatively, these light sources can also be arranged on a separate circuit board, with their light being directed onto the personalization side via mirrors and possibly via associated optics, mirrors and light-guiding elements. The light of the LEDs illuminates the focus area 34, which is imaged by the rod-lens array on the sensors 29. One of the lines 31 consists of LEDs which are in the UV wavelength range from 350 to 420 nm A second row 32 contains LEDs whose light is in the NIR wavelength range between 780 nm and 1050 nm, typically 950 nm or 980 nm. The third line 33 is equipped with white light LEDs.

In further embodiments, more than three LED rows may be provided. In addition, the use of laser diodes is possible, in particular to verify special security features of the travel document such as diffractive structures or optically variable elements

4 shows a second possible embodiment of a mobile verification device 1 based on a mobile communication device 17 with display 18 and keyboard 19 and with an OCR reading module 1, which is used to read the ICAO line 4 of the travel document 2. The arrangement of the receiving opening 11 is selected at the upper part of the mobile communication device 17, but may also be provided in the lower or lateral area. In the receiving opening 11, the travel document 2 with the Personalisierseite 3 and the ICAO line 4 located thereon can be inserted. The travel document 2 may further contain the owner's photo 5, his personal data 6, a radio chip (RFID element) 25 and a security element in the form of a diffractive structure 10. With the Personalisierseite 3 more leaves are connected to the perforated number 7 on the fold 8 (book seam)

As a mobile communication device 17 PDA ^S (Personal Digital Assistant) or mobile phones can be used, in which the OCR reader 28 and an RFID reader 16 integrated or modular grown, for example, be plugged.

In another embodiment, for example, as an OCR reading device 28, a CIS line may be used which, for example, in the

Rear side, preferably integrated in the battery module. Now, if the mobile communication device with the rear-mounted CIS line on the Personalisierseite 3, in particular via the ICAO line 4 is moved, then the scanned data in the mobile communication device 17 can be supplied to an evaluation and / or display in a very simple manner become. The scanned data can be transmitted directly or after internal processing via the communication module 20 wirelessly to a higher-level data network for the purpose of verification. The answer information can be displayed on the display directly or after prior processing in the mobile verification device 1.

With such a mobile verification device travel documents can be checked on the spot in mobile use. In the simplest case, the ICAO line is read out, if the travel document is equipped with an RFID element, this is also read out. The determined data are then in the o.gen. Subjected to verification.

When using a CIS line in the surface area of the mobile communication device 17, in particular on its rear side, the entire data page 3 with the ICAO line 4, the passport picture 5 of the travel document holder, the Personalisierdaten 6, a diffractive structure 10 and further, in FIG. 4 not shown data, in particular security elements are scanned and submitted to the verification process. This verification process can be wholly or partially online in wireless communication via a data network, for example, be processed with a database system or done offline directly in the device.

In order to protect the mobile verification device 1 against unauthorized use, an electronic identification means 26 is provided with which a user must identify himself as authorized. For this purpose, a slot is provided in the device, in which a chip module can be inserted. The identification means can also be realized by a fingerprint sensor and / or a USB plug for a USB token. In particular, the identification means 26 is designed so that it is not visible from the outside. The identification is effected without contact by means of a corresponding transponder chip or RFI D element, which the user carries on the body.

Fig. 5 shows a further embodiment of a mobile

Verification device 1 on the basis of a mobile phone 17 with integrated camera module 21. Today's mobile communication devices already have high-resolution camera modules 21 which are color capable and have a few million pixel resolution as well as for image reproduction displays 18 in the form of TFT or OLED displays and an input keyboard 19. With

In turn, 20 is the communication module for data transmission. On the verification device designed on this basis, an RFID reading unit 16 is also attached on the rear side.

Furthermore, an optional docking station 23 can be provided, which can be connected to an electrical supply network, in particular to the electrical system of a motor vehicle, and can optionally be connected to a data network 24.

To ensure exclusive use by authorized personnel, an electronic identification means 26, for example a chip card, is provided which can be inserted into a corresponding slot in the housing of the mobile telephone. Likewise, the release of the device can also be made without contact and / or biometric data of the claimant. For example, the camera module can be used to record the facial image, the fingerprints or the iris. Optionally, it may be advantageous if suitable adapters are used, which are preset to the camera module 21.

In an expanded embodiment, the camera part of the verification device can be equipped with a double beam path or with two camera modules. These can be used for spatial imaging or for verification of diffractive safety structures and for recording interference phenomena.

In machine-readable travel documents are not only a plurality of personal data but also a variety of security features, which can be detected in particular only when lighting in the UV or IR range. For this purpose, a lighting unit 27 is provided on the verification device 1, which features in combination with the camera module

21 makes verifiable. The lighting unit 27 is integrated in the example shown in the device. But it can also as well as a front optics as be placed module or adapter. The camera / illumination part 21, 27 may in particular be designed as a pivoting part in order to be able to record both the document and biometric data.

As a lighting unit 27 are primarily modulated and pulsable light sources in question, in particular white light flash lamps, LED elements and laser diodes. In particular, LED elements are extremely durable and can be modulated up to high frequencies or operated with short pulses and are available from a wavelength of about 350 nm to the sensitivity range typical for silicon CMOS or CCD sensors up to about 1050 nm. Optionally, whitish LED elements with a high power spectrum and laser diodes may also be considered. Although the latter do not offer such a broad selection and require a corresponding electrical voltage supply, they are especially suitable for evaluating diffractive structures.

With the exemplary embodiment shown in FIG. 5, the entire personalization page 3 with the ICAO line 4, the photo of the passport holder 5, the personal data 6 and the diffractive structure 10 of the travel document 2 is recorded with the at least one camera module 21. If appropriate, the further document pages connected to the personalization page via the book seam 8 can also be recorded with the hole numbering 7. If the travel document also has an RFID element 25 with the stored personal and biometric data of the holder, then its data are fed to the verification device via the RFID reader. In case of insufficient ambient lighting, the exposure is recorded using the exposure device 27. Wavelengths in the UV and NIR range are used for the fast and reliable determination of special security features, and the temporal on and off behavior of the luminescence of security dyes and pigments is investigated. Since the images can be taken from different viewing angles and distances, the images are normalized and equalized to uniform size. The exactly defined ICAO line is used for this. For the same purpose can also the known dimensions of the boundary of the passport are used.

The operation of the verification device according to the invention presupposes, first, that the user identifies himself, for example, as authorized by a chip card and his personal code or by his biometric data. In operation, the optical reader 22 first reads the standardized machine-readable line (ICAO line) of the travel document. Their data are processed in the data processing unit according to a predetermined algorithm, on the basis of which data the RFID reading module reads out the electronically stored data of the machine-readable travel document including the holder's biometric data, in particular its photograph, and forwards it to the data processing unit. The data processing unit performs verification on predefined test guidelines and can access data of a database network online or partially on-line by means of wireless communication via a mobile radio network, police radio network, via W-LAN, Bluetooth, IR communication interface or via a docking station. Insofar as the mobile verification device does not carry out the authenticity check autonomously, the verification can also be partially or completely transferred to a central location. The data of the travel document, the photo and the verification result are displayed on the graphic display unit. Thereafter, the authorized auditor concludes the verification process.

The optical reader unit used are camera modules, OCR reader modules and CIS lines. For verification of security printing and lamination properties, UV, IR, RGB and white light exposure sources are used, in particular based on modulatable LED and laser elements with low power consumption.
