Description

  The present invention uses the name of the person ordering the creation of the original hard copy using special toner or special ink in order to prevent duplication of illegal hard copies from the original hard copy created from electronic information including confidential information. The present invention relates to a system for displaying date and time on a paper surface in a latent image.

Technical background

  In information security, when confidential information is flowed electronically, it is possible to automatically keep a communication record and store it in a method that cannot be easily deleted, and is used as a measure for preventing information leakage.

  However, the original hard copy of printed matter or printed matter containing confidential information obtained from confidential electronic information is in a state where no record of who ordered and when it was printed or what was printed remains on hard copies such as paper, Management of the original hard copy of printed matter or printed matter containing confidential information is a weak point in information security.

  Conventionally, many proposals have been made as countermeasures against illegal hard copy. In this case, efforts have been made from the viewpoint of preventing copying and forgery. In other words, in the efforts to prevent copying, the content of a hard copy, which is an original printed matter or printed matter, can be clearly read, but the content of a hard copy, which is a copy of this original, cannot be read. It has been aimed to show that even if the contents of the hard copy, which is a copy of, can be read, it is clearly counterfeit.

As a new anti-counterfeiting technology, paper has been proposed in which characters such as “impossible” and “COPY” emerge when copying with a color copier (HYPERLINK http://www.toppan.co.jp/aboutus/release/article457.) html http://www.toppan.co.jp/aboutus/release/article457.html ). Depending on the copying machine, characters may not be well revealed, and there is a disadvantage of being uncertain.

  Several methods have been proposed from the viewpoint of copy protection. For example, there is one using colored paper. The paper is colored with a dye or pigment to reduce the difference in absorption of the irradiated light between the non-image area and the image area, thereby eliminating image exposure on the photoreceptor and preventing re-copying. However, in order to make copying impossible, it is necessary to increase the coloring density of the paper, which hinders the reading of the original and cannot completely prevent re-copying.

  Some use paper printed with camouflage patterns. A copy of a background pattern printed on a sheet of paper, and when copied, the background pattern is clearly copied and difficult to read, but it is legible and expensive.

  Some copiers detect paper with special processing using sensors to stop the copying operation. The copier sensor specially installed at the time of re-copying the paper is treated with magnetic material or infrared absorbing material, etc. to detect it and stop the copying operation. However, there is a drawback that copying is carried out if the copying machine is used.

  Some use ink or toner that emits or discolors heat or light. It is intended to prevent re-copying with originals using ink or toner that emits or loses color due to the heat or exposure of the copier. There is uncertainty that the photocopier may not emit or extinguish light. There is a disadvantage that cannot withstand the use of time.

In addition, there is a copy prevention sheet using the difference in gloss of the color material. This sheet has a true cancer determination portion formed on the base surface, and the true cancer determination portion is composed of a base made of dark ink with low reflectance and an overprint / varnish portion applied thereon. ing.

  However, although various means including these have been proposed, none of the methods is intended to suppress duplication such as illegal hard copy. Currently, by using colored paper for confidential documents, it is recognized that it is a confidential document, attracting attention to the confidential document, and restricting the creation of illegal hard copies.

  Therefore, the idea of suppressing illegal hard copy duplication of printed matter or printed matter from an original hard copy such as printed matter or printed matter including confidential information did not exist in existing literature.

  The problem to be solved by the present invention is to suppress duplication of illegal hard copies or the like from original hard copies of printed matter or printed matter that is printed from confidential electronic information or includes confidential information that has been printed. Duplicator copies original hard copy of printed matter or printed matter created by a printer (hereinafter also referred to as printer) or printed matter from confidential electronic information input to a recording medium such as a personal computer (hereinafter also referred to as personal computer) It is intended to provide a mechanism in which the name, creation date, etc. of the person who ordered the creation of the original hard copy appear on the hard copy that is a duplicate of the original hard copy when it is copied by a machine or scanner. .

  In the present invention, the term “hard copy or the like that is a duplicate of the original hard copy” includes the same contents as the duplicate hard copy when the original hard copy is read by a scanner, before the duplicate hard copy is created. The display of the reproduction electronic information is also included.

  In the present invention, when an original hard copy of a printed matter or printed matter is created by a predetermined method from a confidential electronic information input to a recording medium such as a personal computer in an information management area by a predetermined method, Separately print the name of the person who ordered the creation of the original hard copy, the creation date and time, etc., on the same sheet of paper with a special toner or special ink so that it is relatively invisible to the naked eye. Print.

  As a result of using the special toner or special ink of the present invention, most copying machines commercially available when a duplicator reproduces the original hard copy from the original hard copy by a copying machine or a scanner in an information non-control area or the like In a scanner or the like, the name, creation date, and the like of the person who ordered the creation of the original on a hard copy, which is a duplicate of the original hard copy, appear so as to be visible at a higher density than the original hard copy.

  That is, the present invention, in particular, the problem solving means of the present invention is configured to preliminarily store the electronic information including the secret in order to prevent duplication of an illegal hard copy from the original hard copy created from the electronic information including the secret. And the name of the person who orders the creation of the original hard copy and / or the date and time when the original hard copy is created is displayed as a latent image on the paper. A system for creating the original hard copy by a method.

  The predetermined method is a method of printing or printing with a general printer or printing machine connected to a conventional personal computer.

  Further, in the present invention, after the electronic confidential information is electronically sent from the recording medium of the original personal computer to the recording medium of another personal computer in the information management area, another original hard copy such as printed matter or printed matter, etc. The name of the person ordering the creation of another original hard copy, the date and time of creation, etc. must be on the same paper so that it is relatively invisible to the naked eye with special toner or special ink separately from the confidential information text. Printed or printed as a latent image.

  By using the special toner or special ink of the present invention, the latent image can be printed or printed with a color density that is relatively invisible to the naked eye, and the contents of the printed hard copy including confidential information etc. When reading the text, the name of the person who made the dark original hard copy appears on the duplicate hard copy copied from the original hard copy using a copier or scanner. The most important feature is that, using this special toner or special ink, characters other than the main text such as the name of the original hard copy creation command are latently printed or printed on the same sheet so as to be visible.

  The special toner or special ink of the present invention includes, for example, a substance powder capable of reflecting light, has a light color, and the binder is transparent. As the substance powder, metal powder is preferable. A powder having a metal reflecting surface is blended in special toner or special ink. Not only a metal but also a metal vapor-deposited film-containing material and a plastic strip powder having a reflective surface can be used.

  The original hard copy printing method or printing method using the special toner or special ink of the present invention is not particularly limited. The original hard copy printing method using the special toner or special ink of the present invention includes inkjet, PPC (toner transfer), thermal transfer, and the like. Therefore, the special ink of the present invention includes an ink constituting an ink ribbon used in the thermal transfer system. Printing methods using the special ink of the present invention include letterpress, planographic (offset), intaglio (gravure), and stencil.

  The printer or printing machine used in the present invention is not particularly limited, but a two-color machine is preferable.

  When the original hard copy, which is a printed matter or printed matter including confidential information, is duplicated by using the special toner or special ink of the present invention, the name of the original hard copy creation instruction and / or the duplicate hard copy, etc. The date and time of creation of the original hard copy appears visibly, and the source of confidential information becomes clear, making it easier to pursue a leak route. The original hard copy creation instructor becomes cautious about the handling of confidential information as a source, and can prevent information leakage from the original hard copy.

  According to the present invention, when an illegal copy is viewed, the outflow route is easily determined, and therefore, the ability to suppress illegal copy acts on all persons accessing the original hard copy.

  The copying machine or scanner, which is a copying machine as an object that exhibits the effect of preventing illegal hard copy copying according to the present invention, senses the regular reflection light of the incident light from the light source of the copying machine, which is mainly used in the market. This is valid for all duplicating machines that do not.

  In carrying out the present invention, in order to suppress duplication of an illegal hard copy or the like from an original hard copy created from electronic information including confidential information, the electronic information including confidential information is displayed on a sheet by a predetermined method, The original hard copy is created by a method in which the name of the person who orders the creation of the original hard copy and / or the date and time when the original hard copy is created is displayed latently on the paper surface using special toner or special ink. Use the system.

  That is, when carrying out the present invention, when creating an original hard copy which is a printed matter or printed matter of electronic information from electronic information including confidential information using a printing machine or printing machine, first, the printer or printing machine is a personal computer or the like Incorporates software that prints or prints the original hard copy creation commander name, creation date, etc. widely on paper.

  Next, when electronic information including confidential information is printed or printed using embedded software or the like, the electronic information including confidential information is printed or printed on a predetermined sheet of paper by using a predetermined toner or ink. The original hard copy is obtained, and the name of the original hard copy is instructed, the creation date and time, etc. are printed or printed on the predetermined paper surface by this predetermined method using special toner or special ink. A latent image is printed or printed on a partial or entire area of the printing unit.

  Here, the predetermined toner or ink is a toner or ink used in a predetermined method such as a printing method such as ink jet, PPC, or thermal transfer, and a printing method such as a relief plate, an intaglio, a planographic plate, or a stencil.

  The predetermined paper surface is a paper surface such as inkjet paper, PPC paper, thermal transfer paper, or printing paper suitable for each printing method or each printing method.

  The same paper surface is used for displaying, printing or printing confidential electronic information and printing or printing the name of the original hard copy creation commander. In this case, it may be performed once or twice. Preferably, before electronic information including confidential information is displayed on a sheet by a predetermined method, the name and / or date of creation of a person who orders the creation of an original hard copy using a special toner or special ink is latently imaged. Print or print on paper. The area of the paper on which the name of the original hard copy creation commander is printed or printed is preferably 50% to 100% of the area of the paper on which confidential information is displayed, printed or printed.

  A powder surface capable of reflecting light of a wavelength included in a light source such as a copying machine or a scanner reflects incident light only in a specific direction. There is a high probability that this reflected light does not reach the light receiving unit of a copying machine or a scanner. Accordingly, the image portion or image portion printed or printed with special toner or special ink containing particles having a powder surface having the ability to reflect such light, that is, the name of the original hard copy creation instructor, etc. Or it is treated as a color close to black by a scanner or the like. For example, the original hard copy creation instruction containing confidential information etc. or the powder surface with metallic luster present in the part where the creation date and time are printed glitters, but this part after duplication has a high probability of black spots The characters representing the original hard copy creation command or the creation date and time appear visibly on the duplicate hard copy or the like and become clearly visible.

  The special toner or special ink of the present invention is relatively invisible to the naked eye and does not interfere with the reading of confidential information on the original, but can be clearly seen on a reproduction hard copy or the like created by a copying machine or a scanner. Become. For example, by blending metal powder having a high light reflection ability.

  FIG. 1 shows an information management area and an information non-management area where fraud may occur. In the information management area, electronic information including confidential information is input and stored in the parent computer, and this electronic information is printed on the paper by a printing machine connected to the parent computer, and the original hard copy creation commander name, etc. Is printed as a latent image on the same sheet.

  In the non-information management area, when an illegal duplicate hard copy is duplicated by a duplicator and scanner from the original hard copy that is a printed matter created in the information management area, the original hard copy printed latently Since it is clear that the creation commander's name and the like appear visibly, duplication is suppressed. In this case, when electronic information including confidential information taken out from the original hard copy by the scanner in the information unmanaged area is displayed on the personal computer screen, duplication is similarly suppressed.

  Also, in the information management area, from the child computer to which electronic information is sent from the parent computer, the electronic information is printed on the paper and printed on the original hard copy by the printer connected to the child computer as well as the parent computer. The name is printed as a latent image on the same sheet. Therefore, even in the information non-management area, copying of the original hard copy created from the child personal computer is also suppressed.

  When the present invention is implemented, it is only necessary to slightly change the existing personal computer-related mechanism. For example, it is only necessary to add a printing function or printing function using the special toner or special ink of the present invention to general printing software of a personal computer. The special toner or special ink of the present invention may be newly added, or may be filled in one ink cartridge or ink supply source of an existing two-color printer or printer. The special toner or special ink of the present invention can be produced by adding, for example, metal powder and a dispersant to an existing colorless or slightly colored transparent ink.

  Thus, it can be said that the present invention can be implemented without problems.

FIG. 1 shows a specific example of the system configuration and duplication mode of the system in order to explain the mechanism of the present invention.
