Description
SECURITY DOCUMENT COMPRISING AN INTEGRATED CIRCUIT AND
AN INTEGRATED DISPLAY ELEMENT
The invention relates to a security document comprising an integrated circuit and comprising a display element integrated in the document.
Security documents, such as identification cards, passports, identity cards, driver's licenses, credit cards, customer or travel tickets and the like, which contain personal and/or product-related data and must therefore meet corresponding security requirements, are increasingly being equipped with integrated circuit components (IC) in which the personal and/or product-related information is stored. In the course of security checks, this information is read out and used for authentication, that is to say for checking the authenticity of the document, and for verification, that is to say for monitoring correspondence with the person presenting the document. Chip modules with contacts as well as contactless and also dual interface chip modules are conventionally used for this purpose.
They contain large scale integrated circuits with a correspondingly programmable silicon-based memory element. The programmable memory elements are typically embodied in the form of an EEPROM (electrically erasable programmable read only memory). Standards and quality requirements for relevant security documents are set out in ISO 10373.
Apart from the aforementioned electronic equipment, security documents are configured graphically, in principle. In this case, the graphical information must correspond to the electronic information. For this ' reason, the electronic writing and the graphical writing of personal and/or product-related data are preferably implemented in a single station. Such personalization requires largely neutral documents which are subjected in said station inter alia to graphical configuration methods such as laser engraving, inkjet and digital printing methods, thermotransfer or thermoprinting methods and embossing operations.
In other cases, documents that have already been graphically prepersonalized are subsequently electronically personalized. In this case, it must absolutely be ensured in a complicated method that the correct document is provided with the correct associated electronic information.
Figure 1 shows the typical architecture of a conventional memory card 1 (Klaus Finkenzeller: RFID
Handbuch [RFID handbook], Carl Hanser Verlag Munich, Vienna 2000). The chip module contact area 5 is represented with six contact areas, wherein V00 denotes the supply voltage, GND denotes ground, RST denotes reset, Vpp denotes the programming voltage, CLK denotes clock and I/O denotes input/output. Smart cards having eight contact areas are also customary. The I/O contact is symbolically depicted with a bidirectional connection 15 to the address and security logic 6.
There is likewise a bidirectional connection between the address and security logic 6 and the EEPROM 7, while the ROM 8 is unidirectionally connected via connection 14 to the address and security logic 6.
Figure 2 shows the computer architecture of a conventional microprocessor card 1 (Klaus Finkenzeller:
RFID Handbuch, Carl Hanser Verlag Munich, Vienna 2000).
The connections between the I/O contact and the CPU 9, between CPU 9 and RAM 10, and also between CPU 9 and the combined unit composed of EEPROM 7 and ROM 8 are in each case bidirectional, where of course the ROM 8 is itself internally driven unidirectionally again.
Some embodiments of the present invention is based on the object of further improving the technology of security documents.
The goal set is achieved according to some embodiments of the invention by means of a security document comprising an integrated circuit for communication with an external reading and/or writing device, and comprising at least one display element which is integrated into the security document and serves for visually representing personal and/or product-related data, wherein the display element is connected to the integrated circuit in a bidirectional manner and is simultaneously used in this way by the integrated circuit as a memory array.
In this case, the invention is based on the insight that an electronic display field with bidirectional driver electronics can be used not only for visual representation but at the same time as a programmable memory for the IC element. The memory in the IC of the smart card, usually an EEPROM, can in this way be completely omitted or at least partly replaced by the electronic display field, depending on the application.
In the same way, the display field can, if appropriate, also be used as an at least partial replacement for a ROM or EPROM.
It is advantageous that the display element is programmable and personalizable in this way exclusively by means of the integrated circuit, where personalization is understood to mean the document-related individualization. This involves writing in preferably biometric information of the owner of the document, such as picture of face, fingerprints, specimen signature, but also name, date of birth, etc.

In other cases, documents that have already been graphically prepersonalized are subsequently electronically personalized. In this case, it must absolutely be ensured in a complicated method that the correct document is provided with the correct associated electronic information.
Figure 1 shows the typical architecture of a conventional memory card 1 (Klaus Finkenzeller: RFID
Handbuch [RFID handbook], Carl Hanser Verlag Munich, Vienna 2000). The chip module contact area 5 is represented with six contact areas, wherein V00 denotes the supply voltage, GND denotes ground, RST denotes reset, Vpp denotes the programming voltage, CLK denotes clock and I/O denotes input/output. Smart cards having eight contact areas are also customary. The I/O contact is symbolically depicted with a bidirectional connection 15 to the address and security logic 6.
There is likewise a bidirectional connection between the address and security logic 6 and the EEPROM 7, while the ROM 8 is unidirectionally connected via connection 14 to the address and security logic 6.
Figure 2 shows the computer architecture of a conventional microprocessor card 1 (Klaus Finkenzeller:
RFID Handbuch, Carl Hanser Verlag Munich, Vienna 2000).
The connections between the I/O contact and the CPU 9, between CPU 9 and RAM 10, and also between CPU 9 and the combined unit composed of EEPROM 7 and ROM 8 are in each case bidirectional, where of course the ROM 8 is itself internally driven unidirectionally again.
Some embodiments of the present invention is based on the object of further improving the technology of security documents.
The goal set is achieved according to some embodiments of the invention by means of a security document comprising an integrated circuit for communication with an external reading and/or writing device, and comprising at least one display element which is integrated into the security document and serves for visually representing personal and/or product-related data, wherein the display element is connected to the integrated circuit in a bidirectional manner and is simultaneously used in this way by the integrated circuit as a memory array.
In this case, the invention is based on the insight that an electronic display field with bidirectional driver electronics can be used not only for visual representation but at the same time as a programmable memory for the IC element. The memory in the IC of the smart card, usually an EEPROM, can in this way be completely omitted or at least partly replaced by the electronic display field, depending on the application.
In the same way, the display field can, if appropriate, also be used as an at least partial replacement for a ROM or EPROM.
It is advantageous that the display element is programmable and personalizable in this way exclusively by means of the integrated circuit, where personalization is understood to mean the document-related individualization. This involves writing in preferably biometric information of the owner of the document, such as picture of face, fingerprints, specimen signature, but also name, date of birth, etc.
The display element according to some embodiments of the invention is embodied in bistable fashion, such that it retains its information in the de-energized state. Such displays are preferably formed as electrophoretic, ferroelectric or cholesteric liquid crystal displays. The display element can also be formed by a passive or active, self-luminous display system based on OLED elements. In the case of active OLED elements, the display is activated with the aid of a reading device or by means of a built-in power source, whereby the representation then becomes visually discernible.
The integrated circuit is preferably contained in a chip module that is fitted in the document in such a way that it cannot be removed therefrom without destruction. The display element is then via external contacts of the is inserted into a milled-out cavity of the document, wherein the milling work operation is conducted in such a way that the internal terminals are also uncovered in the process.
In the embodiment as a contactless smart card, the programming can be effected with increased RFID field strengths, if appropriate, if the operation is effected in closed surroundings with corresponding shielding.
For this purpose, inductively or capacitively acting coupling fields can be provided in the document, the increased power being introduced in each case by means of said fields. After programming has been effected, it is possible to initiate an irreversible operation which - e.g. causes an internal .wiring element to acquire high impedance or interrupts it or causes a short circuit, such that a renewed programming and a changing of the data written in are no longer possible.
The display and memory system is organized according to rows and columns that are driven electrically. Driver circuits are required for this purpose. Since the display field can be regarded as a type of EEPROM, wherein the memory points are the visually discernible pixels, the driver is embodied in a bidirectional manner according to the invention. With the use of bistable display elements, the driver can be altered irreversibly after programming has been effected, such that the information written in can only be read. The display element then functions as it were only as a ROM.
The personalization operation can also be established in an irreversible manner by application of a laser pulse or locally acting electric and magnetic fields or e.g. by polymerization to completion of predetermined elements.
The drivers mentioned are usually arranged in direct proximity to the row and column lines of the display field in order not to have to bridge long distances.
However, the display driver IC can also be accommodated as an additional integrated circuit in the chip module.
It is preferably formed in the IC of the chip module itself. In principle, it is also possible to operate the display by means of a display driver IC situated in the reading/writing device.
Bidirectional matrix driver ICs using flip-chip technology can be used for the display field. In this case, relatively fine wiring lines are required for making contact with the IC pads. For this purpose it is possible to use etching-technological extremely fine conductor techniques with conductor track spacings in the range of 10 m to 30 m, but also special printing techniques, e.g. according to the inkjet method.
The serial bidirectional driving of the display element is preferably effected serially by means of two or three electrical connections. In this case, the row and column lines are equipped with capacitances and, if appropriate, with further electronic functions, such as diode functions. In this case, the serial bidirectional connection has one signal line and two voltage supply line, which can be connected directly to a contact chip module or a dual interface chip module internally analogously with regard to making contact with antennas.
Consequently, there are in principle a plurality of possibilities to choose from:
In a simple embodiment, the display element is written to by means of a reading module with contacts. For this purpose, it is merely necessary for the internal serial control lines to be routed toward the outside via corresponding chip module contact areas. In this simple embodiment, it is possible to use a slightly adapted chip module and to form the entire driving electronics in the reading/writing device.
In the embodiment of a dual interface document, the two antenna contacts are additionally connected.
In the embodiment of a document which functions contactlessly, in which no external ohmic connections are available, the entire operation of self-personalization, that is to say of writing the personal and/or product-related data to the graphical display, must be effected exclusively via the wireless interface. For this purpose, it may be necessary to apply increased power to the document, wherein suitable shieldings are used as protection. For power and information coupling, a holelike cutout can also be provided in the document, a coil being arranged around said cutout. The coupling is then effected via an induction core reaching into the holelike cutout.
Biometric data of the owner of the document, such as the picture of the face, fingerprints and the like, are preferably written to the display field. In this case, the visual representation in the display field preferably contains steganographically concealed information, which represents an additional security feature that makes misuse and manipulation attempts even more difficult.
Depending on the area of application of the security document, the writing to and/or altering of the display of the display system must be effected under complicated security-technological conditions. Such in particular cryptographic methods, monitored access authorizations, PIN numbers and the like are customary in the field of memory and smart cards. The chip module's security structure provided in this regard for RFID systems is in this case concomitantly used for deliberate legal changing of the display contents. In this way, it is possible for the security standard such as is conventionally provided for smart cards also at least to be maintained for the security documents according to the invention.
A particular advantage resides in the fact that the display element is integrated in an inseparable laminate composite of the document by printing technology. In this case, two wiring planes may be provided in the form of row and column lines, wherein said planes are connected internally to corresponding contacts of the chip module. In an advantageous development, the display system also additionally has a third wiring plane in the form of a transparent top electrode, which is likewise connected internally to corresponding contacts of the chip module. The invention can be embodied using conventional wiring techniques from flexible printed circuit board production as well as polymer electronics and methods for the printing-technological production of electronic circuits.
The integrated circuit is preferably contained in a chip module that is fitted in the document in such a way that it cannot be removed therefrom without destruction. The display element is then via external contacts of the is inserted into a milled-out cavity of the document, wherein the milling work operation is conducted in such a way that the internal terminals are also uncovered in the process.

For this purpose it is possible to use etching-technological extremely fine conductor techniques with conductor track spacings in the range of 10 m to 30 m, but also special printing techniques, e.g. according to the inkjet method.
The serial bidirectional driving of the display element is preferably effected serially by means of two or three electrical connections. In this case, the row and column lines are equipped with capacitances and, if appropriate, with further electronic functions, such as diode functions. In this case, the serial bidirectional connection has one signal line and two voltage supply line, which can be connected directly to a contact chip module or a dual interface chip module internally analogously with regard to making contact with antennas.
Consequently, there are in principle a plurality of possibilities to choose from:
In a simple embodiment, the display element is written to by means of a reading module with contacts. For this purpose, it is merely necessary for the internal serial control lines to be routed toward the outside via corresponding chip module contact areas. In this simple embodiment, it is possible to use a slightly adapted chip module and to form the entire driving electronics in the reading/writing device.
In the embodiment of a dual interface document, the two antenna contacts are additionally connected.
In the embodiment of a document which functions contactlessly, in which no external ohmic connections are available, the entire operation of self-personalization, that is to say of writing the personal and/or product-related data to the graphical display, must be effected exclusively via the wireless interface. For this purpose, it may be necessary to apply increased power to the document, wherein suitable shieldings are used as protection. For power and information coupling, a holelike cutout can also be provided in the document, a coil being arranged around said cutout. The coupling is then effected via an induction core reaching into the holelike cutout.
Biometric data of the owner of the document, such as the picture of the face, fingerprints and the like, are preferably written to the display field. In this case, the visual representation in the display field preferably contains steganographically concealed information, which represents an additional security feature that makes misuse and manipulation attempts even more difficult.
Depending on the area of application of the security document, the writing to and/or altering of the display of the display system must be effected under complicated security-technological conditions. Such in particular cryptographic methods, monitored access authorizations, PIN numbers and the like are customary in the field of memory and smart cards. The chip module's security structure provided in this regard for RFID systems is in this case concomitantly used for deliberate legal changing of the display contents. In this way, it is possible for the security standard such as is conventionally provided for smart cards also at least to be maintained for the security documents according to the invention.
A particular advantage resides in the fact that the display element is integrated in an inseparable laminate composite of the document by printing technology. In this case, two wiring planes may be provided in the form of row and column lines, wherein said planes are connected internally to corresponding contacts of the chip module. In an advantageous development, the display system also additionally has a third wiring plane in the form of a transparent top electrode, which is likewise connected internally to corresponding contacts of the chip module. The invention can be embodied using conventional wiring techniques from flexible printed circuit board production as well as polymer electronics and methods for the printing-technological production of electronic circuits.
The security document according to the invention is produced using lamination technology as a composite composed of a plurality of films and/or flexible printed circuit boards. Flexible printed circuit boards are understood to mean the soldering-temperature-resistant plastic films known from the prior art such as e.g. polyimide (PI), polyether sulfone (PES) or polyether ether ketone (PEEK) and also woven (e.g. FR-4) or nonwoven substrates (e.g. aramid aromatic polyamides). These are provided with a thin copper film and patterned by means of etching using subtractive technology. Two-sided or multilayer flexible printed circuit boards with corresponding plated-through holes can also be produced using this technology. If only a limited soldering resistance is required, it is also possible to use polyester films (PET) using subtractive technology, that is to say with an etched copper or aluminum film. Furthermore, all the substrates mentioned can also be provided with electrical wiring structures by means of so-called additive technology, that is to say e.g. by means of silver, copper or carbon paste printing. Said structures are electrically contact-connected by means of isotropic or anisotropic conductive adhesives. The electrical connection can also be produced by a crimping operation, by means of ultrasound or a similar pressure-temperature effect, in particular for producing an intermetallic conductive connection.
In addition to these largely conventional solutions, an integration of electrical components of printing-technological type can be realized by means of so-called polymer electronics. Even though a parallel driver logic is also possible for this, a serial driving of the display fields or the memory elements is preferred in embodiments of the present invention.
For protection against direct attempts at manipulating the display field, the latter is incorporated into a Fa r a da y cage. By way of example, a thin electrically conductive structure constructed in areal or grid-type fashion in the form of a carbon- or nanotube-containing paste, a silver paste, an ITO (indium tin oxide) paste or an intrinsically conductive polymer layer can be provided in the document on the rear side, while a transparent metal-oxidic paste or a conductive polymer film is used on the front side.
The graphical information provided in a customary manner alongside the electronic display field can be applied by known printing methods and using relief embossing technology.
A power supply source in the form of a solar module, a rechargeable battery or a piezoelectric power source is also provided, if appropriate, in the document according to the invention. In this case, the power source can be activated by means of a pushbutton switch. In this way it is also possible to realize self-luminous displays in security documents which are switched on only as required.
With the incorporation of further security criteria, the personalization operation can be made dependent on the fact that it can proceed only under specific ambient parameters, e.g. with application of electromagnetic irradiation in a specific wavelength range or with application of magnetic fields or laser exposure. Furthermore, through effects of this type, in particular through the use of a specific laser beam pulse, individual elements of a display field can be programmed or irreversibly influenced.
- 9a -Some embodiments of the invention thus make it possible to produce display systems on electronically supported documents of printing-technological, and hence thin flexible embodiment with high contrast, low production costs and high security against forgery.
In accordance with one aspect of the present invention, there is provided a security document comprising an integrated circuit for communication with an external reading and/or writing device, and comprising at least one display element which is integrated into the security document and serves for visually representing at least one of personal data and product-related data, wherein the display element is bistably settable and is connected bidirectionally with the integrated circuit and is thereby usable by the integrated circuit as a programmable as well as a readable memory array.

The electronic display field 4 is connected to the integrated circuit 2 of the chip module 3 via a bidirectional connection 15. Only a unidirectional driving is inherently necessary simply for the display.
However, since the display field here is simultaneously used as a memory array, its contents must at the same time also be able to be read out.

As described previously, the display field is additionally designed as a memory that can be read via the IC 2, and is therefore connected to the IC via the bidirectional line 15.
Figure 5 shows, using the example of a passport 1, the personalization side thereof with the display field 4, the ICAO line 16 and the personalization data 17. The IC 2 can communicate with an external reading/writing device by means of the antenna formed as dipole 12 and uses the display field 4 as an EEPROM replacement via the bidirectional connection 15. Biometric data of the owner of the document, in particular, are displayed as display contents 11 of the display field 4.
