Description

  The present invention relates to a method for creating an identification medium that can be confirmed to be authentic, and a creation apparatus thereof, and more particularly to a mechanism for recording identification information at the same time when a printed material is created.

  As a technique for identifying authenticity, a method using a magnetic material is known (see, for example, Patent Documents 1 to 5). In this identification technique, identification is performed using a difference in output waveform of the magnetic detection device caused by a difference in distribution state of magnetic materials contained in the identification medium.

Japanese Patent No. 2680980 Japanese Patent No. 2718624 Japanese Patent No. 2726794 Japanese Patent No. 2821352 Japanese Patent No. 2821367

  By the way, there are important documents and various certificates as identification targets for determining authenticity. In determining the authenticity of these documents, it is an important issue whether or not the document is officially issued. For example, when a passport is considered, whether or not the passport is officially issued by an official organization of the country is important in the authenticity determination. Therefore, such a document is desired to have an identification function capable of identifying that the document has been issued through a formal issue procedure. Accordingly, an object of the present invention is to provide a technique capable of providing an identification function for identifying authenticity at the same time as creation of a printed material.

  The identification medium producing method of the present invention includes a step of scanning at least a part of a paper in which fibers containing a magnetic material are interleaved by a magnetic detection unit, and identification information based on an output of the magnetic detection unit at the time of the scan And a step of recording the identification information and printing a predetermined print content on the paper.

  A paper in which fibers containing a magnetic material are mixed contains fibers exhibiting magnetism randomly oriented. Since the orientation and distribution of the fibers are unique to each paper like fingerprints and irises, each paper can be identified by using it. That is, when a predetermined portion of the paper is scanned with the magnetic detection device, the output of the magnetic detection device changes according to the orientation state and distribution state of the fibers. The change in output of the magnetic detection device (output waveform in the time axis direction) is different for each paper. Therefore, each paper can be identified by comparing changes in the output of the magnetic detection device.

  In the above invention, when predetermined printing is performed on a paper in which fibers containing a magnetic material are inserted, a predetermined portion of the paper is scanned by the magnetic detection means, and the output of the magnetic detection means at that time is detected. To do. Then, a predetermined conversion operation is performed on this output to generate identification information for this paper. For example, a change in the output of the magnetic detection means is detected on the time axis, and is sampled using an A / D converter to obtain digital data. This digital data is predetermined according to a predetermined conversion rule. (For example, barcode data or character strings). This predetermined data reflects the orientation state and distribution state of the fibers exhibiting magnetism in the paper, and serves as identification information for specifying the paper. In the above invention, this identification information is recorded when a predetermined print content (for example, the content of a security if it is a security) is printed on the paper. In this way, a printed matter on which predetermined contents are printed and paper identification information is recorded at the same time is obtained. This printed material serves as an identification medium having a function of identifying it from other printed materials. Examples of the recording form of the identification information include bar code and character string printing, printing with magnetic ink, magnetic recording on a magnetic material, and recording of electromagnetic data on an IC chip.

  According to the above invention, first, the paper itself is provided with the discriminability by the fiber containing the magnetic material, and the discriminating data is recorded on the paper as, for example, a barcode or a character string. When identifying this printed matter, the identification information by the fiber containing the magnetic material is detected and converted into electronic identification information according to a predetermined conversion rule. On the other hand, the recorded identification information is read by a barcode reader, an OCR (Optical Character Reader) function, or the like. Then, the identification information obtained from the magnetic information is compared with the recorded identification information. If the correlation between the recorded identification information and magnetic information is determined in advance, the authenticity of the printed matter can be determined from the comparison result. In other words, it can be determined whether or not the printed matter has been issued following a formal procedure. For example, in the case of a passport, it can be determined whether or not it is issued by an official government agency.

  According to this mechanism, the reading side (identification side) is configured to generate an identification information (conversion rule agreement) based on the output of the magnetic detection means performed at the time of printing, and information on a place where the magnetic detection is performed. If you know.

  In the paper material using the present invention, magnetic fibers are randomly entangled with the pulp three-dimensionally, and the entanglement is also randomly determined at the time of papermaking, so that there is no reproducibility. The identification information detected by the magnetic sensor includes not only the planar direction but also the fiber orientation state and distribution state in the depth direction. And it is difficult to examine the state of a three-dimensional fiber in a paper-made state. Therefore, it becomes extremely difficult to artificially reproduce the orientation state and distribution state of the fibers exhibiting magnetism and forge the same paper.

  The print information for identification is preferably composed of characters (including numbers) or barcode data (including two-dimensional barcode). In addition, a predetermined image can be used as print information for identification. Further, a magnetic stripe, MICR (Magnetic Ink Character Recognition), IC chip, or the like can be used as means for holding (or displaying) print information for identification in a paper medium. When the magnetic stripe is used, a magnetic recording medium area is provided in the paper material (or the paper surface), and information for identification is magnetically recorded there. Further, when an IC chip is used, identification information is electronically recorded on the IC chip. In the case of using an IC chip, it is necessary to prepare a paper in which fibers exhibiting magnetism are encased and the IC chip is embedded (or pasted). The identification media of the present invention can be applied to various documents, securities, rights documents, certificates, licenses, banknotes, directives and instructions, cash vouchers, tickets, passports, various permits, passbooks, government offices. Various certificates issued by (such as seal certificates and registry books).

  In the present invention, the identification information to be recorded may be associated with the print content of the text printed on the printed matter. For example, in a document printed using the present invention, in addition to the unique magnetic information indicated by the printing paper, barcodes and characters that are printed separately in addition to information based on the document to be printed that is the content of the document Print identification information such as columns is created. In this way, the print identification information represented by the barcode or character string can include unique information regarding the contents of the print document in addition to the unique information of the paper. Therefore, the identification function indicating that the printing of the document content and the identification information are simultaneously performed can be ensured, and a high forgery prevention effect can be obtained. Information extracted from the printed content includes encoded characters (including numbers), encoded number of characters, encoded number of lines, encoded character size and line spacing And the like, the appearance frequency of a predetermined character coded, the combination of these, and the like.

  The present invention can also be understood as an identification medium creation device. That is, a magnetic detection means for detecting magnetic information from at least a part of paper in which a fiber containing a magnetic material is inserted, an identification information generation means for generating identification information based on an output of the magnetic detection means, and the identification It can also be grasped as an identification medium creation device comprising a storage means for recording information and printing a predetermined print content on the paper.

  According to the identification medium creating apparatus, for example, when printing an important document that is strictly prohibited to be copied, a printing apparatus that gives a function as an identification medium to the document simultaneously with printing out can be obtained. For example, this printing apparatus uses paper containing fibers containing a magnetic material as printing paper, and simultaneously prints identification information based on the read magnetic information when printing predetermined items on this paper. In this case, when the printing paper is fed into the apparatus, a predetermined part of the paper is scanned by the magnetic detection device, the magnetic information is acquired, converted into the printing information, and the predetermined printing content on the paper Printed with. According to this mechanism, a printed matter with an identification function can be created simply by performing predetermined printing using paper containing fibers containing a magnetic material as paper. By using this identification medium creation device, it is possible to easily create certificates, securities, and the like having an identification function. The identification medium creating apparatus of the present invention can be applied to a printing apparatus, a copier, a FAX, a multifunction machine having two or more functions of these devices, and the like.

  According to the present invention, magnetic information included in a printing paper is read when printing a predetermined content, and data obtained by converting the read magnetic information is recorded on the printing paper as a character string or a barcode. As a result, a printed matter having a function as an identification medium can be obtained simply by printing. That is, according to the present invention, it is possible to provide an identification function for identifying the authenticity simultaneously with the creation of the printed material.

1. First Embodiment (1-1: Identification Medium Creation Device)
FIG. 1 is a schematic diagram showing an outline of an identification medium creating apparatus using the present invention. FIG. 1 shows a printing apparatus 101, a personal computer 102, a printing paper 103a (before printing), and a printed material 103b in a state after printing on the printing paper 103a. The printing apparatus 101 is an example of an identification medium creation apparatus according to the present invention. In this example, the printing apparatus 101 prints content (such as a document) created by the personal computer 102 on a printing paper 103a. FIG. 1 shows a state in which a print content 105 such as a document is printed on a printed material 103b by printing. The printing paper 103a is a paper in which magnetic fibers are mixed throughout the paper. In this example, the fiber exhibiting magnetism is an acrylic fiber in which magnetic powder is dispersed. In the printing paper 103a, the acrylic fibers are randomly distributed three-dimensionally.

  An identification information reading area 104 is set in a predetermined area of the printing paper 103a. Although the identification information reading area 104 is clearly shown in FIG. 1, this area is an area arbitrarily set as an area for reading the identification information. However, it is not known which part is the identification information reading area 104. Of course, the identification information reading area 104 can be recognized, but from the viewpoint of improving the security, it is preferable not to clearly indicate the location. Note that since the reading of information using magnetism is possible anywhere on the paper, the identification information reading area 104 may be anywhere on the printing paper 103a.

  FIG. 2 is a block diagram illustrating an outline of the printing apparatus 101. As shown in FIG. 2, the printing apparatus 101 includes a magnetic detection device 201 having an MR head, and a magnetic signal detection device 202 that converts an output of the magnetic detection device 201 into a predetermined signal form. ing. In addition, a print head 203 that prints predetermined print information on the print paper 103 a and a print control device 204 that drives the print head 203 are provided. Although not shown, the printing apparatus 101 includes other mechanisms for transporting the printing paper 103a. This is the same as a normal printing apparatus. As the magnetic detection device 201, a magnetic head or Hall element having another structure can be used.

  The magnetism detection device 201 scans the identification information reading area 104 set on the printing paper 103a and detects magnetic information indicated by the portion. At this time, first, the reading head (MR head) of the magnetic detection device 201 is brought close to the identification information reading area 104 of the printing paper 103a while the printing paper 103a is being conveyed through the printing apparatus 101. Then, the magnetized fibers contained in a random state in the printing paper 103a pass one after another in front of the reading head. Since the fiber which shows magnetism exists at random, the output of the magnetic detection apparatus 201 becomes a waveform according to the random state. This waveform is a strong and intense waveform as indicated by reference numeral 205, for example.

  The magnetic signal detection device 202 A / D converts the output of the magnetic detection device 201, generates barcode data based on the A / D conversion, and sends it to the print control device 204. This bar code data reflects the distribution state and orientation state of the fibers indicating magnetism existing in the identification information reading area 104, and serves as magnetic identification information for identifying the printed matter 103b. Also, predetermined print data (for example, data of the print contents of a document) is output from the personal computer 102 shown in FIG. 1 to the printing apparatus 101, and is taken into the print control apparatus 204. The print control device 204 drives the print head 203 based on the barcode data output from the magnetic signal detection device 202 and the print data sent from the personal computer 102 in FIG. 1, and based on each data. Printing is performed on a predetermined location of the printing paper 103a. By this printing, the print content 105 and the barcode 106 are printed as shown in FIG.

(1-2: Identification function)
The orientation state and distribution state of the fibers exhibiting magnetism in the individual printing paper 103a are unique to each paper like fingerprints and irises. This is because fibers exhibiting magnetism are randomly taken into the material of the paper during paper folding. Therefore, the output waveform 205 of the magnetic detection device 201 described above is also different and unique for each sheet. For this reason, the barcode data based on the output waveform 205 of the magnetic detection device 201 as shown in FIG. 2 is information for identifying each sheet.

  In order to confirm the authenticity of the printed material 103b, the magnetic identification information indicated by the identification information reading area 104 can be read by the magnetic detection device, the print identification information indicated by the barcode 106 can be read by the barcode reader, and both can be compared. Convert to data format and compare. If the printed material 103b is genuinely printed using the printing apparatus 101, the magnetic identification information indicated by the identification information reading area 104 matches the print identification information indicated by the barcode 106. Thereby, it can be determined that the printed material 103b is authentic. If the two do not match, it can be determined that the paper or barcode is not official (that is, not authentic).

(1-3: Operation of creation device)
Hereinafter, the operation of the printing apparatus 101 illustrated in FIG. 1 will be described. Here, an example will be described in which important documents that are strictly prohibited for copying are created by printing. FIG. 1 shows print contents 105. This printing is performed when the printing paper 103 a before printing is inserted into the printing apparatus 101 and passes through the printing apparatus 101. As shown in FIG. 2, when this printing is performed, the identification information reading area 104 (see FIG. 1) is scanned by the magnetic detection device 201 with respect to the printing paper 103 a drawn into the printing apparatus 101. At this time, the output of the magnetic detection device 201 has a waveform 205 corresponding to the orientation state and distribution state of the fiber exhibiting magnetism. This output is converted into barcode data by the magnetic signal detection device 202, and this barcode data is further sent to the print control device 204. The print control device 204 performs predetermined printing exemplified by reference numeral 105 in FIG. 1 based on the print data sent from the personal computer 102, and simultaneously prints the barcode 106 based on the barcode data. In this way, the printed material 103b on which the predetermined document 105 and the barcode 106 serving as identification information are printed can be obtained. The printing paper 103 has a function as an identification medium.

(1-4: Printing paper)
Hereinafter, the printing paper 103a will be described. FIG. 3 is a conceptual diagram showing a schematic structure of the printing paper 103a. FIG. 3A shows the outline of the whole, and FIG. 3B shows a layer structure. As shown in FIG. 3, the printing paper 103 a has a three-layer structure in which a first layer 301, a second layer 302, and a third layer 303 are stacked from the bottom. The first layer 301 and the third layer 303 are normal paper layers. The intermediate second layer 302 sandwiched between them is a layer in which fibers 302a showing magnetism including magnetic powder are mixed in and dispersed in the paperbrushing process. According to this structure, the layer containing the fibers can be sandwiched from above and below by the layer not containing the fibers, and the fibers can hardly be detached.

  First, the characteristics of the printing paper 103a will be described. When the printing paper 103a is scanned using a magnetic detection device, the magnetism of the fibers 302a exhibiting randomly distributed magnetism is detected. This detection signal shows strength according to the random orientation state and distribution state of the fibers 302a. The distribution state and orientation state of the fibers 302a are determined at the time of squeezing, but they are different each time the squeezing is performed. Accordingly, the distribution state and orientation state of the fibers 302a are different for each paper. Since the output waveform of the magnetic detection device described above reflects the difference in distribution state and orientation state of the fibers 302a, each output sheet can be identified individually.

  Next, a manufacturing method will be described. First, an example of a method for manufacturing the fibers 302a exhibiting magnetism entering the printing paper 103a will be described. FIG. 4 is a conceptual diagram showing a method for manufacturing the fiber 302a exhibiting magnetism shown in FIG. The fiber 302a can be obtained by mixing powder of a material exhibiting magnetism into a molten resin raw material and then ejecting the liquid resin raw material from the pores in a normal resin fiber manufacturing process. .

  Hereinafter, a specific manufacturing example of the fiber 302a will be described. First, a mixture of a molten acrylonitrile copolymer and a ferrite powder having an average particle size of 0.5 μm is put into a fiber manufacturing apparatus 401. Acrylonitrile copolymer is the main raw material of acrylic fiber, and ferrite particles function as magnetic powder. The particle diameter of the ferrite powder is about 0.3 to 4.0% of the diameter of the fiber to be manufactured. The ratio of ferrite powder to acrylic fiber (weight of ferrite powder / weight of acrylic fiber) is 70% by weight. The mixing ratio is suitably in the range of about 50% to 85% by weight.

  When the mixture of the two is put into the fiber production apparatus 401, the temperature and pressure conditions are adjusted, and this mixture is ejected from the pores at the tip of the nozzle 401a to form thread-like fibers. Here, a fiber 402 having a thickness of 30 μm is manufactured by adjusting various conditions. The fiber 402 has ferrite powder particles dispersed therein, and exhibits magnetism while being an acrylic fiber. The fibers 402a (FIG. 3) exhibiting magnetism are obtained by cutting the fibers 402 into a length of 5 mm.

  Next, an example of a method for manufacturing the printing paper 103a shown in FIG. 3 will be described. FIG. 5 is a conceptual diagram of a paper making apparatus for making the printing paper 103a. The paper making apparatus shown in FIG. 5 includes a paper making belt 503 conveyed by guide rollers 501 and 502. The papermaking belt 503 is a blanket-like belt to which the raw material of the crushed paper sticks. The papermaking belt 503 is in contact with the circular nets 504 to 506. The circular nets 504 to 506 are rotatable, and a part of each of the circular nets 504 to 506 is immersed in slurry 507a to 509a that is a raw material for paper.

  Reference numerals 507 to 509 denote slurry containers storing the slurries 507a to 509a. Here, the slurry 507a is a raw material slurry for forming the first layer 301 in FIG. 3, the slurry 508a is a raw material slurry for forming the second layer 302, and the slurry 509a forms the third layer 303. It is a raw material slurry for. Here, the slurries 507a and 509a are ordinary paper material slurries. The slurry 508a is obtained by mixing the above-described acrylic fiber containing ferrite particles with a paper material slurry. The mixing amount of the acrylic fiber is set so that the acrylic fiber is about 1% by weight in the paper-made state. In addition, it is appropriate that the content weight percent of the acrylic fiber in the paper-made state is in the range of about 0.3 to 5 weight percent.

  In papermaking, the guide rolls 501 and 502 are rotated counterclockwise, and the circular meshes 504 to 506 are rotated clockwise in synchronization therewith. At this time, the first layer 301 is rolled on the circular net 504, and the rolled layer is attached to the papermaking belt 503. Further, the second layer is spread on the circular net 505, and the second layer is further stuck on the layer on which the first layer 301 is deposited on the surface of the papermaking belt 503. In addition, the third layer is spread on the circular net 506, and the third layer is further stuck on the layer on which the second layer 302 is deposited on the surface of the papermaking belt 503. In this way, a stacked body in which the first layer 301, the second layer 302, and the third layer 303 are stacked in three layers is obtained. The laminate layered between the three layers is conveyed in a state of being adhered to the papermaking belt 503, and further peeled off at the guide roller 511, and wound up as a papermaking layered product 510 (a layered product prior to becoming paper). The roller 512 is wound up. The paper sheet laminate wound around the winding roller 512 is dried and appropriately cut, whereby the printing paper 103a can be obtained.

  By providing a region where the slurry 508b does not adhere or weakly adhere to the surface of the circular mesh 505 shown in FIG. 5, a structure in which the second layer 302 is not partially formed or thinned can be obtained. In this case, a “watermark display” can be formed by using a predetermined portion of the second layer 302. By using this “watermark display”, it is possible to put characters and designs based on the “watermark display” on the printing paper 103a.

  Here, a description has been given of a structure in which normal paper-like layers are arranged one above the other and a layer in which fibers exhibiting magnetism are interposed therebetween, but the layer structure is not limited to this. For example, a structure in which a plurality of layers containing magnetic fibers are stacked, and a protective layer is provided on the front and back surfaces to prevent the fibers from dropping off.Ordinary paper layers and layers containing magnetic fibers are alternately placed. A stacked structure, a combination of these structures, or a structure including these structures in part can also be employed. In these structures, in order to prevent the fibers from falling off, protective layers may be provided on the front and back surfaces of only the layer in which the fibers are encased.

  The magnetic material dispersed in the resin fibers may be short fibers instead of grains. The magnetic material is preferably soft magnetic, but may be hard magnetic. As the magnetic material, magnetite, permalloy, iron, and other materials known as magnetic materials can be used. As the fiber base material, resin materials that can be molded into fibers such as PET, nylon, polyester, and polypropylene can be selected in addition to acrylic. The material of the paper constituting the paper is not particularly limited, and a material suitable for the purpose can be selected.

(1-5: Reading device)
Hereinafter, an example of a reading device for identifying the authenticity of the printed matter 103b shown in FIG. FIG. 6 is a conceptual diagram showing the configuration of the reading device. In FIG. 6, the magnetic detection device 601 detects magnetic information in a predetermined area of the printed material 103b. This function is the same as that of the printing apparatus of FIG. The magnetic signal detector 602 detects the output of the magnetic detector 601 and converts it into a data format that can be compared with the barcode data. Reference numeral 603 denotes an image sensor which reads the barcode 106 (see FIG. 1). The barcode reader 604 converts the output (barcode data) of the image sensor 603 into comparison data. The data comparison unit 605 compares the output data of the magnetic signal detection device 602 and the output data of the barcode reading device 604, and determines whether or not they match. The display device 607 is a display that displays the determination result of the data comparison unit 605. The reading apparatus also includes a transport system that transports a sheet to be read (not shown).

  When the printed material 103b shown in FIG. 1 is taken into the apparatus, the printed material 103b is conveyed in the direction of the arrow 606 by a conveyance system (not shown). At this time, the magnetic detection device 601 detects magnetic information in a predetermined area (identification information reading area 104 in FIG. 1). This magnetic information is converted into data of a predetermined format by the magnetic signal detection device 602 and output to the data comparison device 605 as magnetic identification information. On the other hand, the barcode 106 (see FIG. 1) printed on the printed material 103 b being conveyed is read by the image sensor 603, and the output is sent to the barcode reading device 604. The barcode reader 604 converts the output of the image sensor 603 into data of a predetermined format as print identification information.

  The data comparison device 605 compares the output data of the magnetic signal detection device 602 and the output data of the bar code reading device 604. If both data are the same, it is determined as “authentic”. , “Not authentic” is determined. In addition, a signal including the determination content is generated and output to the display device 607. In response to this signal, the display device 607 is displayed as authentic or not authentic (for example, character display or ◯ × display).

  When a character string is used as print identification information instead of a bar code, an image processing apparatus having an OCR function is arranged instead of the bar code reader 604. In this case, the data converted by the magnetic signal detection device and the code obtained from the character string are compared by the data comparison device 605.

  Note that a scanner with an identification function can be obtained by arranging the functions of the reading device shown in FIG. 6 in the scanner. In this case, the determination result may be displayed on the display of a personal computer to which the scanner is connected.

2. Second Embodiment Hereinafter, a device for improving the forgery prevention function of the printed material 103b will be described. In the present embodiment, the barcode 106 is created based on the magnetic identification information read from the identification information reading area 104 and the description content of a predetermined portion (for example, the nth line of the text) of the print content 105. That is, the barcode 106 includes information related to the print content 105, and associates the barcode 106 with the print content 105.

  For example, the magnetic identification information read from the identification information reading area 104 is digitized according to a predetermined calculation rule to obtain a first number sequence, and the first few characters in the fifth line of the print content 105 are also numerical values according to the predetermined calculation rule. To obtain a second number sequence. Then, a third number sequence is obtained from the first number sequence and the second number sequence by a predetermined method, and barcode data for printing the barcode 106 is created based on the third number sequence. According to this method, since the barcode 106 includes the magnetic data indicated by the identification information reading area 104 and the contents of the print content 105, it is not possible in principle to forge only the document or forge only the barcode 106. become. That is, in order to pass the authenticity determination, the barcode 106 and the print content 105 must be printed at the same time, so that it is very difficult to forge only one of the prints later. Thereby, for example, it is possible to make it extremely difficult to illegally obtain the printing paper 103a on which the print content 105 is not printed in advance and then print the text (print content 105) later. Thus, according to this aspect, it is possible to strictly identify that the identification information is printed simultaneously with the issuance. For this reason, it becomes suitable for the identification function which determines whether it was issued through the formal issue procedure.

  In order to realize this mode, the print control apparatus 204 shown in FIG. 2 selects character data of a predetermined portion to be encoded from predetermined print data, and further encodes it. In the print control device 204, based on the code created from this print data and the magnetic identification information sent from the magnetic signal detection device 202, the barcode data sent to the print head 203 (the barcode 106 in FIG. 1). Bar code data) is generated.

  For authenticity determination, a configuration in which a scanner that reads the print content 105 (see FIG. 1), an OCR function, and a coding device that codes identification information is added to the configuration shown in FIG. 6 is prepared. In this case, the image information of the character read by the scanner is converted into character data by the OCR function, and the character data of a predetermined portion in the character information is encoded by the encoding device. Next, in the encoding device, an identification code is generated (restored) based on the code obtained from the print content 105 and the magnetic identification information output from the magnetic signal detection device 602. Finally, the print comparison information output from the barcode reading device 604 is compared with the previous identification code in the data comparison device 605, and if both have a predetermined relationship (for example, the same), it is authentic, otherwise it is false. judge.

  This embodiment can be grasped as follows. That is, in the method of creating an identification medium according to the present embodiment, the step of scanning at least a part of the paper in which the fiber containing the magnetic material is interleaved by the magnetic detection unit, and the output of the magnetic detection unit at the time of the scan Generating a magnetic identification information based on the information; obtaining an identification code based on the magnetic identification information and a predetermined print content; and recording the predetermined print content and the identification code on the paper. It can be grasped as a configuration provided. In this case, the identification code can be printed and displayed using a bar code, a numerical value, a character, a figure, or the like. Further, the identification code can be recorded as magnetic data in a sheet, or can be recorded on an IC chip incorporated in the sheet.

  In addition, the identification medium creating apparatus according to the present embodiment includes a magnetic detection unit that scans at least a part of paper in which fibers containing a magnetic material are inserted, and a magnetic field based on an output of the magnetic detection unit at the time of scanning.

3. Third Embodiment As a modification of the second embodiment, an example can be given in which the number of strokes of each line of a print document and the total number of strokes are converted into data, and the print identification information is created by tying it with magnetic information. For example, at the time of printing, information on the number of characters in a predetermined line in a printed document is encoded, and combined with magnetic identification information to generate print identification information, which is further converted into a barcode. The barcode of the print identification information is printed simultaneously with the printing of the document. If the contents of the printed document are falsified, the number of strokes changes, so the information regarding the printed document read at the time of identification does not match the identification information indicated by the barcode. Thereby, authenticity can be determined.

4). Fourth Embodiment As a method of recording identification information on paper, a method of recording magnetic information on a magnetic stripe provided on a paper instead of printing a barcode or the like may be employed. For example, the printing paper 103a shown in FIG. 1 is prepared by providing a magnetic recording area at the portion 106. Then, the magnetic information read from the identification information reading area 104 is recorded in this magnetic recording area when the printing content 105 is printed. At the time of authenticity determination, the magnetic recording area 106 is read by the magnetic sensor and collated with the magnetic information read from the identification information reading area 104.

  As a method of making the portion 106 a magnetic recording region, a method of sticking a small piece functioning as a magnetic recording region to the portion 106, a method of pouring a magnetic powder or a fiber showing magnetism in the region, a magnetic property in the region Examples thereof include a method of forming a magnetic layer capable of magnetic recording by applying a paint or binder in which powder is dispersed. In addition to the fiber exhibiting magnetism described in the first embodiment, a fiber in which a hard magnetic material suitable for magnetic recording is dispersed is separately prepared. The portion denoted by reference numeral 106 may be a magnetic recording area. Further, the fiber indicated by reference numeral 302a in FIG. 3 may be a fiber in which hard magnetic powder is dispersed and held, and an arbitrary place may be used as a magnetic recording region.

5. Fifth Embodiment As a method of recording the identification information on paper, there is a method of recording the identification information on an IC chip embedded (or attached) on paper instead of printing a barcode or the like. For example, the printing paper 103a shown in FIG. 1 is prepared by embedding an IC chip in the portion 106. Then, the magnetic information read from the identification information reading area 104 is electromagnetically recorded on the IC chip when the print content 105 is printed. When the authenticity is determined, the identification information is electromagnetically read from the IC chip embedded in the portion 106 and collated with the magnetic information read from the identification information reading area 104.

6). Other Embodiments The print content 105 shown in FIG. 1 may be a graphic or a map in addition to a document. That is, the print content 105 may be anything as long as it is a printable display. In addition to important documents, the printed matter 103b on which predetermined contents are printed includes securities, rights documents, certificates, licenses, banknotes, instructions and instructions, cash vouchers, tickets, passports, various permits, passbooks And various certificates issued by the government office (such as seal certificates and registration books). FIG. 1 shows a system for printing print data sent from the personal computer 102. For example, a storage medium is directly connected to the printing apparatus 101 and stored in the storage medium. You can also print the contents. Further, the printing apparatus 101 may be connected to a LAN or the Internet, and data may be received via these networks and printed. Further, FIG. 1 shows an example in which identification information is displayed by a barcode 106, but instead of the barcode 106, numbers, alphabets, other language characters, or a combination thereof are displayed. Also good. In this case, the magnetic signal detection device 202 uses a predetermined conversion rule set in advance, and generates numbers and alphabets to be printed based on the output of the magnetic detection device 201.

  Further, by combining the functions of the printing apparatus shown in FIG. 1 and the reading apparatus shown in FIG. 6, it is possible to obtain a multifunction machine having an identification medium creation mode and a collation mode (identification mode). In this case, one apparatus can be used as an identification medium creation apparatus or an identification medium identification apparatus.

  Further, authentic identification can also be performed using the printing apparatus shown in FIG. First, consider a case where a number sequence is printed instead of the barcode 106. In this method, the printed matter 103b on which the predetermined content 105 and the barcode 106 are already printed is passed through the printing apparatus 101 again to perform blank printing. That is, the printed matter 103b is again passed through the printing apparatus 101, and a printing operation is performed without printing any document or the like. In this case, the identification information reading area 104 is read again, and a numerical sequence based on the information read at this time is printed again on the portion of the barcode 106.

  If the printed material 103b is authentic, the numerical sequence printed on the barcode 106 is the same as the display that has already been printed, and the two overlap. On the other hand, if the printed material 103b is a fake, a different display content is printed. In this way, the trueness can be determined by looking at the overlapping state of several sequences printed on the barcode 106 portion.

  The function of the identification medium creating apparatus using the present invention may be applied to a FAX, a copier, and further to a multifunction machine having functions of printing, copying, and FAX. For example, in the case of a FAX machine, a paper that uses the present invention is set, and a printed document that can be identified as a document output from a specific FAX machine is created by printing the print content sent to the FAX machine. can do. Further, for example, in the case of a copying machine, it is possible to obtain a document that can identify that the document obtained by copying is created by a predetermined copying machine. For example, consider a case where a copy of a resident's card, certified copy of family register, seal certificate, registry book, etc. is received at a public office. In this case, it may be asked later whether or not these documents are genuinely copied and delivered at the public office. When the present invention is applied to a copying machine, it is possible to identify whether or not the output printed matter is a thing using a predetermined copying machine, and thus it is possible to accurately perform such authenticity determination.

  In order to enhance the forgery prevention effect, the print identification information may be encrypted and printed as a barcode or a character string. In this case, a function for decrypting the encrypted data is arranged on the reading device side. By doing so, forgery based on the printed content can be made more difficult. In addition, by incorporating the printing date and the identification number of the device that performed the printing into the identification information recorded on the paper, the information can be used as an identification target. In this case, the printing date, the manufacturing number, the management number, etc. that can identify the device (printer or copier) that performed the printing are encoded and printed as print identification information. For this reason, it is possible to read the print history at the time of reading, and further specify the device that performed printing. In this case, it is possible to further increase the discriminability regarding whether or not it has been issued following a formal procedure. Further, according to this aspect, since the history cannot be read unless it is a dedicated machine, the print history can be read if the dedicated machine is used, but a printed matter that is difficult to read illegally is obtained. Can do.

  The present invention can be used in a system for issuing a printed material having an identification function.
