Description

METHOD AND APPARATUS OF MANUFACTURING A STICKER CONTAINING AN INFORMATION OF AN OFFLINE DOCUMENT AND GOODS, AND A STICKER MANUFACTURED BY SAID METHOD}

The present invention relates to a method and apparatus for producing a sticker comprising information of a document or article off-line.

Specifically, the present invention outputs the information of the document or article on the offline as a sticker in the form of an encrypted pattern or a combination of barcode and watermark and attaches it to the document or article (packaging of the article), and subsequently reads the attached sticker. By doing so, it is possible to authenticate documents, to make electronic documents, or to confirm detailed information of articles.

In particular, the present invention relates to official documents used in administrative institutions, reaper documents used for private business between individuals, commercial documents exchanged between individuals or companies for profit, and forms used in certain card forms to improve the efficiency of effective business. It is to prevent the originals of the same various documents from being damaged by the user's reading and to easily grasp the contents of the documents.

In addition, the present invention is to make it possible to check the contents and detailed information about the packaged goods that can not be confirmed by the box or envelope, without opening the package.

As the related arts related to the present invention, there are watermarking technology as a technology for preventing illegal copying of a work, and a bar code technology as a technology for making predetermined information of articles and documents into symbols and recognizing it by a reader.

One of them, watermarking technology, inserts information that can be identified only by the copyright holder into various digital works such as images, audio, and video, and extracts the copyright holder hidden in the copyrighted work when unauthorized use or distribution is performed without the permission of the copyright holder. This is a technique for determining the authenticity of a work. If it is necessary to identify the original owner, such as disputes of ownership in the distribution of digital works, that is, digital content, a watermark embedded in the digital content can be detected to provide a basis for exercising the rights of ownership, copyright, and the like.

However, the existing watermarking technology has an advantage of protecting copyright information by concealing and inserting information about the content without the user's knowledge.However, the amount of information that a user can insert using the watermarking technology is not drawn. The disadvantage is not large.

Barcode technology, on the other hand, was originally designed to improve the management efficiency of supermarkets, and was designed to reduce waiting time in front of the cashier and to automatically update inventory records at the same time as sales. With great achievements in retail applications, other industries are increasingly adopting bar codes.

Barcodes are divided into continuous and discontinuous types according to the symbol expression method.Discontinuous type refers to barcode symbology, in which each character is separated independently, there is a space between characters, and each character starts immediately and ends immediately. . Even when decrypted, they are treated character by character. Unlike the continuous symbology, the continuous type does not have a gap between characters, and each character is a bar code symbology that starts with a bar and ends with a space. The end of a character is distinguished by the beginning of the next character.

In addition, barcodes are classified into one-dimensional (linear) barcodes and two-dimensional barcodes according to the arrangement of data, and two-dimensional barcodes are subdivided into multi-layered, matrix, circular, hexagonal, and color barcodes according to the shape and arrangement of the bars. Can be.

This conventional barcode technology is a system that is widely used in all industries, and has the advantage of improving the management efficiency and easily knowing the information on the goods by inserting a symbol using a simple symbol structure, but the barcode is visually exposed. Since the method of attaching or printing on the article has a problem that it is difficult to check the forgery of the barcode.

The present invention is to solve each of the problems of the conventional watermarking technology and bar code technology to enable a more improved type of document authentication and confirmation of the document or article details.

In addition, with the recent development of digital technology, offline online has been actively progressed and various services have been made. However, various types of information provision services are available for online target content, but for offline content, information about the content (document or article) is stored in a separate document, so additional information about the content is provided. There is a problem that management is required.

In addition, in the case where the contents are off-line, if the contents are packaged by an invisible method, there is a problem that the package must be opened to check the contents. If the contents are off-line, the user uses it for reading or checking. There is a problem that the document is worn, damaged.

The present invention is intended to solve the problems described above, the object of the present invention is to create a sticker that can verify the authentication and detailed information of the document and to attach it to the document, thereby preventing forgery or alteration in the circulation of the document offline Check for forgery.

Another object of the present invention is to provide a method for easily converting an offline document into an online document through the information included in the sticker, and also reducing the possibility of forgery in the conversion into an online document.

Still another object of the present invention is to make a sticker capable of confirming detailed information of an article and attach it to the article, thereby making it possible to collectively manage the article and detailed information and to facilitate information retrieval of the article.

It is a further object of the present invention to prevent, wherever possible, damages resulting from the use of the original of a document or article.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a process of manufacturing a sticker including information of a document offline according to a first embodiment of the present invention.

Referring to FIG. 1, the apparatus 100 for manufacturing a sticker according to the first exemplary embodiment of the present invention includes a document converter 120 for converting an off-line document 110 into a digital file format, and a target document. An encryption unit 130 for encrypting by an encryption method, a compression unit 140 for compressing an encrypted document, an error correction unit 150, a pattern generation unit 160 for shaping and forming a compressed target document into a predetermined form; And an output unit 170 for outputting the formed pattern in the form of a sticker.

Offline document 110 is an original document that is created offline, not through a computer, or a document that is created through a computer and printed through a printer or the like, or a document in which additional information such as signature or seal is inserted according to a user's needs after printing. In this regard, the document may be an official document used by the above-described administrative agency.

The document converting unit 120 converts a document into a digital file form through an optical characteristic recognition (OCR) device or an optical processing device, and in addition to the process of converting the document, part or all of the text of the electronic file is generated by the OCR program. A process of converting the document into text may be included.

The encryption unit 130 encrypts the target document by using a predetermined encryption key to prevent forgery of the document and leakage of information in the process of distributing the document with the sticker later. The encryption algorithm used is not limited to a specific encryption algorithm, and for example, a twofish encryption algorithm or a blowfish encryption algorithm may be used.

The encrypted target document is compressed by the compression unit 140 using a predetermined compression algorithm, which reduces the size of the target document by removing a duplicate part existing in the data from the encrypted target document through a predetermined process. It protects the encryption key. The compression algorithm used is not limited to a specific compression algorithm, and may use, for example, Shannon-Fano Code compression algorithm or Hoffman Code compression algorithm.

The error correction unit 150 performs a process of adding a predetermined error correction code, and the error correction code used is a burst error correction algorithm or a Reed-Solomon Error Correction algorithm. And the like can be used.

In the pattern generating unit 160, the information of the compressed target document is standardized into a predetermined form, and a pattern having, for example, a two-dimensional square combination of 48 × 48 as one cell may be used. The pattern generation process in the pattern generator 160 arranges the data representing the information of the target document in a series of orders. For example, when the data is represented in binary, the black dot is 1 and the white space is used. Is represented by 0, and it can be arranged in a two-dimensional form in a sequence. Alternatively, it is possible to increase the capacity of data by successively combining and arranging one cell. As a result, the pattern generator 160 generates the encrypted pattern including the information of the document offline.

In the output unit 170, the encrypted pattern is output in the form of a sticker as described above, and the sticker 180 in the form of an encrypted pattern is attached to the document 110 on the offline and distributed. If the document is a document that should not be damaged, such as the original of a government record, it is also useful to seal the original document and attach a sticker outside the sealing medium.

As such, the document 110 to which the sticker 180 is attached can later recognize only the sticker 180 so that the entire information of the document can be grasped, and the comparison of the recognition of the sticker 180 and the overall recognition of the target document, And decryption using a decryption key corresponding to the encryption key to determine whether the document is forged or altered in the distribution process.

Next, a process of producing a sticker including information of a document offline is described according to the second embodiment of the present invention. The second embodiment is distinguished from the first embodiment in that the second embodiment outputs a form in which a barcode and a watermark are combined in the form of a sticker.

2 is a block diagram illustrating a process of manufacturing a sticker including information of a document offline according to a second embodiment of the present invention.

Referring to FIG. 2, the apparatus 200 for producing a sticker according to the second exemplary embodiment of the present invention may include a document converter 215 for converting a document 210 off-line into a digital file form, based on information of the document. The barcode generation unit 220 to generate the barcode 230 by using the key generation unit 240 to generate the watermark key based on the information of the document, and the watermark in the form of an image using the generated watermark key information. A watermark generation unit 250 for generating a), a combining unit 270 for combining the generated barcode and watermark, and an output unit 280 for outputting the combined form of the barcode and watermark in the form of a sticker. It is composed.

The construction of the sticker according to the second embodiment of the present invention except for the output unit 280 is described in detail in the Korean Patent Application Nos. 2002-5943 and 2002-23903, which are briefly described herein. I would like to.

The document conversion unit 215 converts the offline document 210 into a digital file format using an OCR device or the like, and the barcode generation unit 220 converts the barcode 230 based on the content information of the document 210. The watermark 260 including the content information of the document 210 is generated through the key generator 240 and the watermark generator 250.

The generated barcode 230 and the watermark 260 are combined to overlap each other in the combining unit 270, and the combined form of the barcode and the watermark is a sticker of the combined form of the watermark and the barcode through the output unit 280. 290). The output sticker 290 is attached to the document 210 on-line and distributed.

As such, the document 210 to which the sticker 290 is attached can later recognize only the sticker 280 so that the entire information of the document can be grasped, and also through the recognition of the sticker 280 and the entire recognition of the target document, By comparing the barcode information, the recognized watermark information, and the entire information of the recognized target document, it is possible to confirm whether the document is forged or not in the distribution process.

According to the first and second embodiments, the sticker in the form of an encrypted pattern attached to a document offline or a combination sticker of a bar code and a watermark may be used for bringing the document online in addition to checking whether the document is forged or not. .

For example, by scanning only a portion of a sticker attached to a document, an offline document can be easily converted into an online digital file document, in which case the ownership of the document can be verified.

According to the present invention, since the content of the document and its authentication information are attached to the document in the form of a sticker, there is an advantage that the original document can be minimized in the authentication of the document and the use of various forms of the document.

Next, a process of manufacturing a sticker including information of an item rather than a document will be described.

3 is a block diagram illustrating a process of manufacturing a sticker including information of an article according to a third embodiment of the present invention. In FIG. 3 a movie film 310 is shown as an example of an article.

Referring to FIG. 3, according to a third embodiment of the present invention, an apparatus 300 for manufacturing a sticker including information of an article includes an information input unit 320 for inputting information of the article 310 into a memory. And a pattern generator 330 for shaping and forming the information of the article 310 into a predetermined form, and an output unit 340 for outputting the formed pattern in the form of a sticker.

In the information input unit 320, necessary information of the article 310 is input. If the article 310 is a movie film, for example, a manufacturer, a date of manufacture, a movie title, a director, a synopsis, and a reference internet site may be input.

The pattern generation unit 330 performs a function similar to the pattern generation unit 160 of FIG. 1. That is, in the pattern generation unit 330, the information of the input article is shaped into a certain form, and the pattern is, for example, 48. A pattern having a square combination of two-dimensional form of x48 in one cell can be used.

The pattern including the information of the article is output in the form of a sticker at the output unit 340, and the output sticker is attached to the article and distributed. If there is a risk that the original article is damaged by the attachment of the sticker, it is also useful to wrap it in a package made of transparent material and seal it so that the sticker can be recognized inside the package.

An article 350 with such a sticker is advantageous in various applications.

For example, if an online catalog of an article needs to be created, an online catalog can be created by recognizing a sticker attached to the article using a scanner / decoder.

In addition, in the conventional case, there is a disadvantage in that a list containing the article and its main information is separately present, whereas according to the present invention, it is possible to easily manage the information of the article by integrally managing the article and the main information.

Another specific application of the third embodiment of the present invention will be described. Currently, museums and galleries have a voice information system that provides voice information about the exhibit. However, in the case of such voice information, there is a disadvantage that there is an area that cannot be serviced according to the location by using radio waves.
