The technical field to which the invention relates

The invention relates to a base, made of paper and is provided with at least one integrated circuit (IC), to the paper and to document that uses a similar basis, as well as to the protective strip and to optically active document, with integrated schema.

The level of technology

From the patent application Germany No. 19601358 known the basis of this type, which is used for documents with protective elements and banknotes to protect them against forgery and falsification. This is a known basis of the supplied IP, which is embedded in the base and contains certain data. IP performed with the possibility of contactless reader and connected to the base without the possibility of separation from her. Used in takeout by etching or grinding to a desired thickness for inclusion in the paper mass. In order to prevent damage to the schema of the crystal, IP strengthen with the base layer, which also serves to position IP. Advanced IP cover protective chemically resistant layer. The lack of flexibility of such well-known silicon chip is a disadvantage in cases where the basis of the specified type is used for documents with security features, such as banknotes or identification documents. In addition, additional layers and additional operations in the manufacture associated with obtaining the required size, increase the cost basis of the specified type.

The invention

The problem to which the present invention is directed, is to create a paper substrate for use in documents with protective elements, notes, etc. that contains IP and does not have the above disadvantages.

In accordance with the invention the solution of this problem is achieved by creating the basis of the specified type, in which the IC contains semi-conducting organic polymer. In this case, we mean that an electronic circuit is made in a polymeric material, and the content of the scheme is programmed to perform the definition of the education documents with protective elements, such as banknotes. Even sharp folds in the chip of semi-conducting organic polymer does not violate the chip. In addition, the polymer of the IP can be performed directly on the specified size, especially in thickness. At the same time, the cost of manufacturing a chip of this type is about 10% below the minimum cost of the silicon chip.

In polymer chip non-conductivity of the substrate, which is applied to a semi-conducting organic polymer, essentially determines the overall thickness of IP. It is preferable to use a mechanically stable insulator: for these purposes, especially suitable plastic with strong intra - and intermolecular interactions.

Use the IP of the specified type as a protective sign documents with protective elements and similar objects creates a new and powerful means of protection, since the production of these IP too difficult for counterfeiters and usually far exceeds the level of their knowledge and capabilities.

In the context of this description, the term “paper” refers to paper made from natural or synthetic fibers, as well as “paper”, which at the present stage of technology development can be made of plastic is to be one or more IP performed in accordance with prescribed functions. For example, to ensure the reliability actions can include two or more identical polymer chips, so that in the event of damage to one basis and/or is made from it, the product can still be used.

Preferably the organic polymer is selected from polymers with conjugated double bonds, in particular, from the group consisting of oligomeric pentacene, poly(Tianjin vinile) or poly-3 alkylthiophene. Made from one of these materials is described in the work of Brown et al. Science, 270. pp. 972-974, 1995.

Specialists in this field it is clear that in this invention the plastic IC contains, in addition to the semi-conductive polymer layer, additional layers of different polymers. For example, the base may be made of polyimide, on which the formed blocks of polyaniline, serving as source and drain. On top is semi-conductive polymer layer, for example, containing poly(Tianjin vinile). This layer is covered by an insulating layer, for example, from polyvinyldene, and the top overlay layer of polyaniline, serving as a shutter.

In the example implementation of the framework according to the invention the IP reads back the/p>In the case of inductive reading for supplying power necessary winding electrically connected to IP to allow remote reading. In order to provide a readout with small distances, it is necessary that the IP was in contact with the conductor, and this conductor forms a measuring tool capacity, which allows the power supply and read.

According to another preferred exemplary embodiment of the framework on the basis of the invention contains conductive protective strip that is connected to the IP security strip serves as a direct or indirect contact for readout and power supply. In a preferred execution to ensure the required electrical conductivity of the protective strip is metallized, with the exception of the location of polymeric IP, where the metallic coating is interrupted. In the case of a direct power supply current must be provided access to the metal. Possible ways to ensure this access is that the protective strip is on paper or embedded in the pulp, and its metal parts have access through the so-called open. In the best case scenario, one or predpolagaemym appointment basis, for example, for the manufacture of banknotes. For banknotes thickness of the paper base, usually is in the range with an upper threshold of 100 μm. In this case, the thickness of the protective strips is in the range 5-60% of the thickness of the basics. If the paper base has a different thickness, for example, for the manufacture of covers identification document such as passport, the minimum thickness of the protective strip may be 10 μm. Thickness greater than 100 microns irrational for use in paper with protective elements. In the preferred exemplary embodiment of the polymer of IP in the form of protective strips provided more easily recognized protective sign. Containing IP security strip may optionally contain many other protective signs, readily identifiable others, such as dye, fluorescent material, phosphorescent material, a luminescent material and printed characters.

Organic conducting polymers can also be used to supply current to the chip, although in the case of direct contact of the ability of these polymers to a reliable mechanical contact currently still leave much to be desired.

Simple protective strip of electrically conductive polymers proposed in the European who has no properties of the semiconductor, so don't create opportunities to build and save the code in a way that is comparable with a protective strip with built-in IP. Protective strip with built-in IP in accordance with the invention can be placed in a traditional way, for example, fully integrated or incorporated into the paper mass is located in a window or attached on the surface of the document. If you want protection from exposure to chemical substances, electrically conductive organic polymers chip can be coated with chemically resistant not electrically conductive protective layer.

Polymer chip as such does not need to be fully integrated into the paper as it is made in the silicon chip in accordance with the above-mentioned patent application Germany. Alternatively, the polymeric chip can also be located on the substrate surface using conventional technology attachment films, holograms, and other optically active signs, etc.,

Myself IP can also be successfully forming part of the optically active signs of various types such as transparencies, labels, holograms or kinegrams located on or within the framework as an additional protective features. How would the possible execution of the optically active elements of the specified type two separate conductive portions of such elements are used for reading and for power supply, both direct and capacitive way. Conductive portions may be composed of metal, conductive polymer or represent a combination of both.

For the purposes of protection of IP may contain pre-programmed code, the code is laid before turning on the chip in the base.

Optimal IP contains the code essential, inherent properties of the basis in which it is embedded IP.

State of the art polymer IP can only be used permanently, i.e. it can be written or programmed once. The preferred method of preservation code in IP is the use of techniques borrowed from cryptology. The true code is stored in the IP encrypted and decryption is not possible without knowledge of the secret key. Thus, even if it is possible to get chips illegally, the secret key is a powerful and almost insurmountable obstacle that does not allow the simulator to put the message in the document security features and read this message. Protection can be enhanced even more if additional signs, as will be explained in more detail below.

The form of the polymer chip is not a critical factor. Currently, the lower limit for the chip rectangular shape is about 1 mm for recording in IP reasonable number of bits of information. Rectangular IC size 46 mm can carry about 48 bits, i.e. 2 bits/mm2. The ratio of the size of the area for polymer chip (i.e. the ratio of length to width) preferably should not exceed 10:1 to avoid any unwanted complications chip with a higher ratio. The small size of IP creates the ability to cover the chip additional protective elements, as it is usually practiced at the present level of technology. The amount of such additional protective elements are typically large compared to the size of the polymer of IP. Thus, even large IP with sufficient memory capacity to store large amounts of data can be used without affecting appearance of the securities with protective elements. If on paper, with protective elements posted by the combination of chip with another protective element, you must ensure that such additional protective elements does not adversely impact on reading and ve of paper with protective elements, such as banknotes, passports, identification cards and other documents with security features, such as securities.

The development of low-cost IP of this type creates many new opportunities to prevent forgery of securities, starting with a completely new type of electronics (electronic bar code) securities.

Described in further examples of the use of IP as a protective element in the document show the different possibilities with respect to the notes, however, similar opportunities are being created for other documents with security features, such as passports, identification documents, etc.,

The first option refers to the use of paper-based IP, which is fully pre-programmed. IP contains one or more relating to bill codes, optionally in encrypted form. This information may contain nominal value, country, place and/or time of issue, number, etc. For a specific nominal value of the banknote information on each chip are identical with respect to the data of the nominal values of the country and, usually, a manufacturer of paper and/or printed body, and partially different in relation to time the release is highlighted by chip which is partially pre-programmed with a unique code (the first code and a second code. This second code is encrypted by translating the first code. Encryption is performed using a first key. During the audit reads the second code and the second key matches the encoding of the first code. The second code can be incorporated into the chip before placing it in the basis or after him. Cryptographic system of this type is described, for example, in international patent application number WO-A-97/24699.

In this known system is coding and encryption of its own intrinsic properties of the basis. For banknotes take the properties of the surface in a specially selected location, encode them, and then encrypts and stores on the bill in the form of a code pattern printed on the banknote. When checking produce than printed image with properties of the surface using the second key.

Many other properties, as well as distributed randomly in the basis of property used to secure documents in accordance with the known solutions. They are described in particular in international application number WO-A-91/19614 (fiber direction), , is the international application number WO-A-87/01845 (conductive fiber). In all of these cases are used for testing distributed randomly, and therefore, the unique properties of the document. Up to the present time was not suitable chips that could be used in paper a framework for recording and storage (encrypted) code. Accordingly, the encoded property is always preserved by other means, for example, outside of the document itself, or was applied to the document printing method or introduced into it magnetically. Polymer chip, which is used in basis in accordance with the invention, makes possible the use and storage of security features within a document.

Suitable for these purposes, property may be fluorescent properties of the fluorescent fibers are randomly distributed in a certain area of the banknote. However, it can also be used any other property that is measurable and randomly distributed on paper or on its composition. It is mandatory that your property is stably maintained during the entire lifetime of the document. This means that in principle unsuitable is the group of jam, etc.,

The chip can also be stored coordinates special part of the banknote, which defines its accidental properties, and, if necessary, the orientation of the surface under its control. Thus, when checking the banknote is the measurement of a particular parameter on a certain trajectory or does the entire image of the banknote, but the evaluation is based only on data available at the site with encrypted coordinates. The measurement results are compared with the stored code, which refers to the same property in the same location. On the basis of this comparison, which may also be encrypted, the signal rejection or acceptance.

The base polymer chip in accordance with the invention may additionally contain conventional security features such as watermarks, security strips, optically active elements and special chemicals, micro-printing, etc. using well-known techniques to recognize these signs.

The invention relates also to the paper and to the protective document basis, provided, as described above, at least one integrated circuit, which is made flexible is automatically active element, carrying IP containing semi-conducting organic polymer, which is provided with electrical contacts for integrated circuits.

The invention is illustrated by the following example. In this case, as an example, use specific fluorescent properties in certain parts of the document. Many banknotes equipped with a variety of high fiber fluorescence emitting light of different colors. These fibers are distributed throughout the document randomly. Local fluorescence of fibers of different species in a specific location can be encoded and stored in digital form in the chip, then optionally encrypted at the time of manufacture of the document, i.e. at the stage of making paper or printing of the document. During the inspection this area is read again using the coordinates and orientation, which are stored in the chip, and the results are compared among themselves, which is accompanied by rejection or acceptance. The above coordinates and orientation are usually different in each individual bill, so checking is unique to this document because random properties and coordinates unique to this document. Thus, the chip of each individual p is knotty. Code internal properties can be stored in encrypted or not encrypted.

As mentioned above, the use of bases according to the invention is not limited to banknotes. For other documents, such as passports or identification documents can be used biometric property of the rightful owner to create a digital code, which is then written in the IP document. As one illustration of the encoded portion of the digital processing of pictures of the rightful owner, and liable digital processing component is determined by the encoded parameters, unique to each document. Exactly the same as for the above example, to check the document you want recorded in the memory code of the picture and the code coincide with each other. Can also be used and other biometrics, such as fingerprints and their parts stored in polymer chip coded form. It also requires stability encoded and stored in the memory characteristic.
