Description

Official stamp and method for displaying electronical official stamp to prevent of document's countfeit}

The present invention relates to the kanji and display method of the document to prevent forgery, more specifically, it is difficult to falsify the document, even when the forgery of the document can be easily distinguished whether the forgery, such as fundamentally blocking the reproduction of all documents The present invention relates to a method of guiding and displaying documents for counterfeiting that can contribute to the construction of a credit society.

There are many cases where documents or checks are issued by government offices such as tax offices, construction, city halls, wiretaps, etc., or by social organizations such as hospitals, schools, and financial institutions such as banks, agricultural cooperatives, and straits. Examples of such documents are various forms such as resident registration, tax payment certificate, seal certificate, certified copy of register, local tax payment notice, local tax payment receipt, and graduation certificate.

However, fraudulent acts that take advantage of conventional documents or checks by intercepting other people's property or causing others to misunderstand them are common. Such frauds are mainly infringement of private property rights, and the representative ones are used in land fraud. Representative documents forged by land frauds are documents such as a seal certificate and a copy of resident registration, and most of them forge the official seal of various documents issued by the administrative office.

Conventionally, various copy protection and authentication methods have been sought in order to prevent such counterfeiting and maintain a sound trade order. However, they are unable to achieve satisfactory fraud and anti-counterfeiting effects. In particular, due to the rapid development of cloning technology, it is impossible to prevent duplication even if the seal is stamped on the paper in the same way as the original copy, so a technique for effectively preventing duplication for fraud is required. have.

Moreover, because fraudulent acts of counterfeiting of documents or checks are difficult to identify immediately, fraudulent groups recognize the counterfeit laboratories and seek countermeasures after they have achieved their intended purpose and are locked out. It causes huge financial, mental and temporal damages to victims who are the target of the acts, and reveals a gap in public welfare due to police investigation into fraudulent acts.

In particular, since electronic documents can be reproduced indefinitely, authentication problems of electronic documents, which are increasingly being used, are becoming a reality, and authentication methods for them are required.

In order to solve these problems, the government hastened to enact legislation on "electronic officials" and "electronic image signatures", and the "e-government" with the main contents including the electronic approval of administrative affairs and the online sharing of administrative officers among ministries at the State Council. The legislative bill for implementation is deliberated and decided, and is expected to be implemented from July next year.

Electronic officials are intended to be used in place of autographed signatures on electronic documents created by government agencies, and as the use of electronic documents increases in administrative agencies, they are being introduced to activate electronic payments and prevent theft of electronic signatures. Documents used in or between administrative agencies are stamped with "electronic image officer", and documents created by the administrative agency against the petitioner are "electronic officer".

Electronic officials and electronic image managers are encrypted, which makes it impossible to forge, forge or damage electronic documents. However, despite these legislative notices, the development of basic and basic technology for electronic consignees has not yet been completed, and thus, the development of technologies for electronic consignees and electronic image consignees in a non-replicable manner is required.

The present invention is to solve the above problems, an object of the present invention is a document for anti-counterfeiting to easily determine that the output is a duplicated document in the case of illegal copying of documents such as documents or public documents It is to provide a seal and labeling method of the

It is another object of the present invention to provide a method for displaying and displaying a document for preventing forgery that can display a seal for authentication in an electronically created document as well as a printed document.

Still another object of the present invention is to provide a method of displaying and displaying a document for preventing forgery that can be used for a certificate or an official document, such as an official or an image person, and can also be used for general documents to indicate that it is a copy.

In order to achieve the above object of the present invention for preventing counterfeiting of the document, a bar code type data display unit containing predetermined information, and a specific character to be displayed in the vicinity of the data display unit to display a character at the time of reproduction Characterized in that the character display portion printed by the optical watermark microprinting technique for preventing the copying of characters by dispersing the angle of incidence of the light incident on the.

In addition, the kanji display method of the present invention, the first step of generating a data display unit in the form of a bar code including information corresponding to the input character, and displays the specific character to be displayed around the data display unit generated in the first step And a second step of displaying the character display unit by an optical watermark microprinting technique for dispersing the angle of incidence of light incident on the character during duplication to prevent duplication of the character.

According to another feature of the present invention, the character display portion of the official seal can be prevented by using not only the optical watermark microprinting technique but also a means such as a specially treated reflective dye or hologram on the surface of the document.

Hereinafter, with reference to the accompanying drawings will be described in detail the seal and display method of the document for forgery prevention of the present invention.

The present invention is to prevent the copy of the document, it is impossible to copy electronically by copying in a form that can not recognize the portion corresponding to the character when copying the original by fax transmission, copier, scanner, etc., especially the character portion and barcode By linking the contents, it is a method of kanji and kanji marking that can easily determine whether the document is duplicated by double comparison through comparison of character recognition and character contents. The method of the present invention can be applied to all documents for copy protection as well as contributors to play a part in the construction of a credit society.

1 is an example of the document 1 including the official 10 of the present invention, and shows a bill and a receipt issued by a tax office or a ward office for taxes or service charges.

As shown, the official 10 displayed on a part of the bill and the receipt which is a normally issued document 1 includes a data display unit 100 in the form of a barcode including specific contents, and a character display unit formed around the barcode. 102). The barcode of the data display unit 100 may be a one-dimensional or two-dimensional barcode according to the amount of information displayed. In the case of two-dimensional barcodes, it becomes a multilayer barcode such as PDF-417 and a matrix barcode such as QRcode. Of course, other types of barcodes may be used.

The data display unit 100 includes specific information such as a name, an address, a taxable name, and an issuer name for a taxpayer who is to be issued a bill and a receipt. In particular, the contents included in the data display unit 100 of an electronic officer or an electronic image officer to be used by an administrative agency or a public institution, as specified in the legislation, may be such as official name, seal / signature, autograph, cooperation, occasional, regular, etc. This may be the type, date of registration, date of first use, or the reason for grant. As such, the contents included in the data display unit 100 may be changed according to the institution for issuing the bill and the receipt which is the document 1. In particular, in a storage institution for storing taxes, there is an advantage that the data display unit 100 can read the contents using a barcode reader and automate the storage process. The data display unit 100 preferably does not perform a copy protection process so that it can be read through a barcode reader.

A character display unit 102 is formed around the data display unit 100. As the character display unit 102 prints a specific character, the content of the character may, for example, describe a specific part of the content included in the bar code or the information for the institution issuing the bill and the receipt. The character display unit 102 is implemented to display normal characters that can be visually identified using an enlarged device such as a magnifying glass on the original.

However, when copying a bill and a receipt, which is a document (1), by using a copying means such as a fax, a copying machine, or a scanner, the optical watermark microprinting technique is performed so that the characters of the character display unit 102 are crushed and indistinguishable to be reproduced. To print the characters.

Therefore, when the original is duplicated, the generated copy can be distinguished from the original by using the identification status of the text, so that the duplication can be easily confirmed. The character display unit 102 is printed by the optical watermark microprinting technique as a micro-sized character (for example, about 1 to 4 points in size) so that it cannot be identified with the naked eye in a normal state. Since the optical watermark microprinting technique is conventionally known, a detailed description thereof will be omitted. At this time, the overall size of the electronic tube or electronic image tube used should be set to meet the standard. The size of the electronic officer or the electronic image officer is prescribed by law.

Figures 2 and 3 show the state of change of the seal 10 in the original and the replica of the seal 10 shown by the present invention, respectively, illustrating a barcode of the QRcode method which is a matrix method among two-dimensional barcodes. will be.

Referring to FIG. 2, the seal 10 is composed of a data display unit 100 and a character display unit 102. In the original state, as shown in the drawing, the data display unit 100 including a specific cause, and the characters of the character display unit 102 printed on the periphery thereof are composed of characters recognizable through an enlargement means such as a magnifying glass. Characters displayed on the character display unit 102 may be the contents such as the name of the agency that issued the bill and receipt (1). In the character display state, specific characters are displayed by blacking or leaving blanks inside the pixels of each matrix in a rectangular form.

Figure 3 shows the state of change of the seal 10 in the replica when the original copy. As shown, it can be seen that the characters displayed on the character display unit 102 are displayed in a crushed state as a circular or rectangular form in an indistinguishable state. The display form is displayed differently depending on the characters, but in any case, the characters cannot be easily identified. In contrast, the data display unit 100 can be seen that there is no change even after the copy of the original. This is because the data display unit 100 is based on general planar printing, not an optical watermark microproprinting technique, unlike the character display unit 102. Of course, the data display unit 100 may also be configured to make the shape of the barcode figure unrecognizable at the time of duplication by using the optical watermark microprinting technique.

The method of the present invention having the configuration as described above is performed in the following order with reference to FIG. 4A.

First, prepare a document to which the method of the present invention is applied. The document may be applied to various certificates such as the above-mentioned bills and receipts, resident registration documents, certified copies of registered documents, tax payment certificates, seal certificates, local tax payment notices, local tax payment receipts, graduation certificates, etc. .

After the document requiring display of the seal 10 is prepared as described above, character data is input to print the data display unit 100. The character data may be a specific content, such as the name, address, description, document issue number, or official name, seal / signature, signature, cooperation, etc. It may be the same as the type of official seal such as occasional, regular, etc., the date of registration, the date of first use, or the reason for grant.

Of course, it is not a description, but may be a secret code, a character, or a cipher used in an issuing authority. Using this information, it is desirable to easily identify the authenticity of the original document later. It is possible to use a dedicated barcode printing device for inputting character data and printing barcodes.

After the specific character data is input as described above, it is encoded into a barcode, and the converted barcode figure is printed at a predetermined position of the document. Referring to Figure 1 it can be seen that the data display unit 100 of the official 10 is printed on the receipt notice for the ward office of the bill portion. This is to allow the data display unit 100 to easily input and process the data using the barcode reader in the receiving institution after storing the corresponding fee or utility bill using the bill and receipt.

In other words, after receiving a fee, the fee collection clerk of a financial institution such as a bank can easily recognize the data of the payer who paid the fee by reading and decoding the two-dimensional bar code using a barcode reader. At this time, the data display unit 100 is not copy-protected, or only a part of the copy-protection is possible, so that it is possible to read necessary data, for example, data of a payer's name, address and taxable status. It also has the advantage of automating storage management by database of the recognized data.

Bar code reading and modulation by a bar code reader is shown in FIG. 4B. As indicated, reading the tract 10 with a (two-dimensional) bar code reader, and decoding the read data with a hardware (dedicated reading device) to restore the binary data. The restored binary data is decoded again by software to generate text data to complete data restoration and processed using a database program. The bar code reading and decoding process as described above is conventionally known, and thus detailed technical description thereof will be omitted.

The data display unit 100 is executed using printing means dedicated to generating two-dimensional barcodes. Since a printing means dedicated to generating two-dimensional barcodes is conventionally known, a detailed description thereof will be omitted.

After printing the data display unit 100 as described above, the character to be displayed on the character display unit 102 is input again. Character input can be configured using a dedicated printing device such as the data display unit 100, and also prints the input character at a predetermined position of the document. The printing position is disguised as unrecognizable in a normal state by printing with a small sized character such as a border on the periphery of the data display unit 100 in the form of a two-dimensional bar code as shown in FIG.

Although the above description of the present invention has been described with respect to the two-dimensional bar code, it is obvious that the same can be applied to the one-dimensional bar code. In other words, the conventional barcode generation method can be equally applied to the data display unit 100 generated by the matrix method "QRcode" or the multilayer type "PDF417".

Fig. 6 shows an example of a multilayer bar code generated by the PDF-417 method in a two-dimensional bar code. As shown, a plurality of bars are used to contain the data, and this multi-layer bar code may be used in the data display unit 100 instead of the bar code shown in FIG. Displayed in the periphery of the bar code is a description of each bar of the bar code (quite zone, start pattern, ,,) to indicate the configuration state of the bar code.

Shown in Figure 5 is an embodiment of a letter to which multilayered printing is applied. As shown, the character display unit 102 may be configured by printing one character into two parts and printing them to have different depths.

In addition, the characters displayed in the character display unit 102 can be put on the anti-copy lock using a variety of methods. For example, holograms can be applied to displayed characters to prevent duplication. Alternatively, printing can be done using specially treated dyes (pigments). Specially treated dyes can render character recognition impossible, for example by non-uniformly reflecting the direction of reflection of the incident light for replication.

Since the actual character display unit 102 is difficult to print using a printer, it is also possible to use a preprinted form of the document. In other words, after printing the character display unit 102 including the specific information such as the name of the document issuing agency or the authoring organization in advance in the printing shop, the remaining information is converted into barcode information and printed. This makes it possible to prepare the document 1 more easily than using a dedicated printer using multi-layer printing or special dyes.

The data display unit 100 printed in a bar code form may be formed in a graphic format that is commonly used, and in particular, may be produced as a gif, jp (e) g file.

According to the present invention, it is possible to easily determine that the document is a duplicated copy of the document, such as a document, and there is an effect that can be signed for authentication on electronically created documents as well as documents in the printed form.
