Description

  The present invention relates to an information providing medium having a graphic code, an information providing system for imaging a graphic code and providing information related to the graphic code.

  In recent years, consumers' awareness of food safety and security has increased, and a traceability system that grasps the movement of foods has been introduced to ensure consumer confidence.

  A conventional traceability system reads an identification code such as an alphanumeric character, a barcode, or a two-dimensional code specified on a food container, etc., and based on the read identification code, stores a variety of information about the food via the Internet. The various information can be obtained by accessing such as (see, for example, Patent Documents 1 and 2). In addition, other traceability systems are attached to food containers and the like, and have an ability to send and receive information to and from a management system using radio waves, in which various information related to the food is written and the information is recorded. An RFID tag or the like is provided, and various information relating to the foodstuff is disclosed via the Internet so that the various information can be obtained (for example, see Patent Document 3).

  A bar code is a symbol that encodes information using a combination of lines and spaces of different thicknesses, but the amount of information is as small as several tens of bytes, and a 2-byte code such as Kanji full-width kana or binary data should be used. There are restrictions such as not being able to. For example, the egg label uses a 13-digit number or a JAN (Japanese Article Number) code as a distribution code, but only the country name, manufacturer name, and item name can be traced.

  The two-dimensional code is a code having data in two vertical and horizontal directions. Compared to a bar code, the two-dimensional code saves space and has a large amount of information, and can encode information of up to 2953 bytes in binary. However, since the two-dimensional code is expressed in a single color, it is difficult for humans to easily recognize that there is a code there, and it is not suitable for a label where design is important.

  Since an IC tag or the like includes a memory for storing data, a large amount of information can be held. However, in the egg industry where the transaction unit price is low, it is difficult to adopt an IC tag or the like because the burden of several tens of yen does not match the cost effectiveness.

  Therefore, it has been proposed to use a color code image instead of a bar code or a two-dimensional code (see, for example, Patent Documents 4 to 7). The standard color code image is four colors of red, blue, green, and black, and is a combination of blocks consisting of squares of 5 rows and 5 columns. Many kinds of patterns can be expressed. The color code image is conspicuous, and it can be easily recognized that there is a code there.

  For example, in Patent Documents 4 and 5, a shape generated by converting one or more characters or numbers included in code information by a predetermined code conversion table that maps each character and number with a predetermined color or shade, A color code image consisting of a color, a pattern, or a combination of these is acquired, the code information is extracted by decoding with a decoding algorithm, and the target information is obtained from the address information included in the code information.

  Further, in Patent Document 6, a data area and a parity area are identified by distinguishing from a color code image, and colors and shades are recognized from images expressed in the data area and the parity area, and are recognized from the image of the data area. The first parity value is calculated based on color and shade, the second parity value is calculated based on the color and shade recognized from the parity area image, and the parity values are compared. If there is no parity error, the data area image is calculated. The target data consisting of recognizable characters including numbers and symbols is extracted by decoding according to the color and shading recognized from.

  Further, in Patent Document 7, a color code image is acquired, a color or shade displayed in each of a plurality of blocks included in the color code image is recognized, and among the colors or shades of pixels belonging to each block, Recognize the color or shading with the most distribution as the color or shading of the block, and convert the recognized color or shading for each block into the corresponding letters, numbers or symbols to generate code information .

JP 2004-344040 A JP 2006-018420 A JP 2006-055108 A JP 2001-273441 A Japanese Patent Laid-Open No. 2003-006200 JP 2001-319200 A JP 2005-509223 A

  The code image of the conventional color can be noticed by the human being that there is a code by conspicuous by the color, but it is easy to categorize the information and what the meaning is with the code image alone Can't understand. In addition, since the color code image must identify the color of each block, it can only be given some design.

  Consumers want to be able to intuitively understand information on food safety and security, and express code images with a design that is easy to understand not only for machines but also for humans, and information on food safety and security from the code images It is desired to provide a system that can obtain the above.

  The inventors of the present invention have made extensive studies in view of the above-mentioned problems, and have been created using four colors of red, blue, green, and black, which are composed of square blocks arranged in 5 rows × 5 columns. The color of each block of the image code can be recognized from the color in a predetermined range in each block, and the two-dimensional code such as a two-dimensional bar code or QR code (registered trademark) is a gray value in each block. Since it is possible to place a picture or photo in a space that does not affect the recognition of color and gray value, it can be recognized from the identification code such as a color image code or two-dimensional code, and a pictogram or photo It was found that a graphic code which is a human and machine readable graphic symbol fused with the above can be created. By providing this graphic code, it is possible to intuitively understand what kind of information is provided by just looking at it. Alternatively, it is possible to determine the gray value in each block and use it for decoding to easily extract a color or monochrome identification code. Information on can be obtained.

  Here, a pictogram is a code that is routinely used as an easy-to-understand code for emergency exits, traffic signs, toilets, maps, and other guidance symbols. It is realized with understandable pictograms.

  By providing a service using this graphic code, it is possible to increase the support of consumers, and at the same time, to improve the incentives of the business, leading to an increase in consumption and an improvement in product value. The present invention has been made by finding these things, and the above-described problems can be solved by providing the information providing medium and the information providing system of the present invention.

  Here, the information to be displayed can be, for example, information on food safety and security, or added value information with added value. Specifically, in the case of traceability, it can include photographs and videos displaying processes such as processing, manufacturing, and distribution, production location, shipping date, producer name, manufacturing date, and the like. The value-added information can include the type of dish using the ingredients and how to make it. As a picture related to the content of information to be displayed, the above-mentioned pictogram can be cited. Examples of the paper include advertising paper and wrapping paper.

  For the graphic code, in order for the information communication terminal to extract the identification code, the color of the designated range in each area of the graphic code corresponding to each block corresponds to the color of each block constituting the identification code. The With such a configuration, the information communication terminal can extract the identification code, and can obtain the corresponding information from the database based on the identification code.

According to the present invention, a database for storing a plurality of information;

  In response to the reception of the authentication identifier included in the identification code from the information communication terminal, the information providing system compares the authentication identifier with the authentication identifier held by the information communication terminal. An authentication server for authenticating the connection of the information communication terminal can be further included. After authenticating the connection, the authentication server can transmit the graphic code to the information communication terminal and display it on the display means provided in the information communication terminal. In this case, the extraction unit extracts the identification code, and the communication unit acquires information to be displayed on the display unit from the database using the identification code.

  When the information providing medium is a display device, the authentication server receives the authentication identifier included in the graphic code displayed by the display device in response to the authentication of the information communication terminal and compares it with the authentication identifier held by itself. If they match, the connection of the display device to the network is authenticated, and the same graphic code as the graphic code transmitted to the information communication terminal can be transmitted to the display device for display. The user can confirm that the graphic code displayed on his / her information communication terminal is the same as the graphic code displayed on the display device and the authentication is successful.

  The information providing medium of the present invention comprises a combination of blocks of a plurality of colors or a plurality of lines having a certain gray value, an identification code for identifying information, and a picture, photo or video related to the content of the information It has a graphic code that fuses and.

  This graphic code has the following functions. The function will be described for the case of using eggs. One is the ability to track and retrospectively manage the person responsible for the movement and quality control from the egg farm to the table. As a specific example, it is a function which can monitor the image | video and data in which a hen's egg is passing the suitable egg-washing process in a selection packaging equipment. This function can contribute to the minimization of accidents and product recovery risks.

  The second is a function that can reduce the anxiety about the quality of eggs and feel trust, that is, it can easily understand the classification of information and its meaning intuitively visually. It is a function. Reassurance can be produced by providing consumers with an intuitive understanding of quality control and the ability to easily trace to safety-based information at any time.

  The third function is to improve the quality of eating habits. A specific example is a function that enables distribution of cooking recipes and nutrition information using chicken eggs. This function realizes a healthy diet, develops the right choice of food, learns cooking techniques and skills, and freely participates in information exchange such as creative dishes and local dishes. It can be used as a place for consumers to listen to consumers and risk communication with eggs.

  FIG. 1 illustrates pictograms and graphic codes as pictures associated with identification codes and information contents. The identification code shown in FIG. 1 (a) is a two-dimensional code in which five square blocks 10 of four colors of red, blue, green, and black are arranged side by side. With this combination, over 17 billion types of patterns can be realized. By assigning the identification code of each pattern to each information, the information can be identified based on the identification code. The identification code shown in FIG. 1 (a) is used to identify information in which eggs laid by chickens on a farm are managed and distributed. For example, the identification code can include a country name, manufacturer name, product number, and the like. The identification code can also include an address where information is stored. This identification code is not limited to 5 × 5 blocks, and may be 7 × 7 blocks or 9 × 9 blocks depending on the number of information to be provided. Further, the identification code may be a two-dimensional barcode consisting of a plurality of lines and a plurality of barcodes arranged vertically and horizontally, a QR code (registered trademark) formed by a lattice pattern, or the like.

  The pictogram shown in FIG. 1 (b) is a picture showing that an egg is being washed. Pictograms are routinely used as human-readable codes for emergency exits, traffic signs, toilets, maps, etc., and can be realized with pictograms that anyone can understand at a glance without the need to understand grammar. It is what is done. In FIG. 1 (b), from this picture, it is possible to recall the classification of information in which eggs laid by chickens on the farm are managed for cleaning. This pictogram can be drawn, for example, in a single color of green only.

  The graphic code shown in FIG. 1 (c) is a graphic symbol obtained by fusing the identification code shown in FIG. 1 (a) and the pictogram shown in FIG. 1 (b). This graphic code is formed by combining and integrating the identification code shown in FIG. 1A and the pictogram shown in FIG. 1B, and corresponding to each block constituting the identification code shown in FIG. The color of the specified range in each area is created so as to be a color such as red, blue, green, and black of each block. Here, in consideration of the overall design and color balance, a chicken picture is placed on the upper right side of the paper, and a plurality of egg pictures are placed in the center. In addition, in order to identify the red block of the identification code shown in FIG. 1 (a), the picture of the chicken or egg that is the graphic part including the range is red, and the range is used to identify the black block. The picture of the egg that is the graphic part to be included is drawn in black.

  FIG. 2 is an enlarged view of the graphic code. In FIG. 2, the graphic code is divided into areas 20 corresponding to 25 blocks by broken lines, and a designated range 21 in the area 20 is indicated by a broken circle. These broken lines are not actually provided, but are provided for ease of explanation.

  The designated range 21 may be any range as long as it is within the region 20, but a circle having a predetermined diameter may be drawn from the center 22 of the region 20 to be a portion therein. The diameter of the circle can be determined such that the area of the circle is about 10-40% of the area of the region. In addition, the number shown here is an illustration and is not limited to this.

  In the graphic code, only the color of the designated range 21 in the area 20 needs to be the color of the block. Therefore, the color outside the designated range 21 in the area 20 takes into consideration the overall design and color balance. It can be arbitrarily determined.

  This makes it possible to design various types, and it is possible to provide multiple graphic codes with different pictograms with the same identification code, or it is possible to provide multiple graphic codes with different identification codes with the same pictogram. It is. In the former case, it is recognized as a completely different design by human eyes, but it is recognized as the same code in machine color recognition. In the latter case, on the contrary, it is recognized as the same design by human eyes, but is recognized as a different code in color recognition by a machine. From these facts, the graphic code can be provided according to the contents that the user and the provider want to appeal to the consumer, and can also be standardized as a graphic symbol that can be shared throughout the food business.

  When using a two-dimensional barcode or QR code (registered trademark) consisting of a plurality of lines as an identification code and fusing them with a pictogram to create a monochrome graphic code, it is difficult to identify by color. It can be identified by a shading value representing the shading of the color. In this case, the code portion has a certain gray value, and the other portions are expressed by other gray values. As a result, a code portion consisting of a plurality of lines can be identified from the gray value, and the identification code is extracted from the arrangement of each line such as the interval between the plurality of lines, the thickness and length of each line, and the direction in which the lines extend. be able to. These two-dimensional barcodes and QR codes (registered trademark) are generally composed of a black line and a white space. However, if the color of the line and space can be identified by a gray value, It may be a color.

  This graphic code is provided by being printed on a label attached for an advertisement or a sign, printed on an advertisement paper or a wrapping paper, and displayed on a display device. Therefore, these labels, advertisement paper, wrapping paper, packaging containers, and display devices can be provided as information providing media. The information providing medium may be any medium as long as it can provide information via a graphic code, and any medium to which a graphic code is attached can be targeted.

  The graphic code is picked up by an information communication terminal provided with image pickup means, and the identification code is extracted in the information communication terminal. The information communication terminal acquires information from the database using the extracted identification code, and the user can confirm the content by viewing the information displayed on the display screen of the information communication terminal.

  FIG. 3 is a diagram illustrating a configuration of an information providing system for realizing the above processing. The information providing system includes a database 30 that stores a plurality of information, an information providing medium 31 having a graphic code, and an information communication terminal 32. The database 30 is connected to a network 33, and authentication servers 34 and 35 are further connected to the network 33. The authentication server 34 functions as a gateway used to enable communication between networks using different media and communication protocols, and enables communication with the information communication terminal 32.

  In this configuration, a graphic code displayed on the information providing medium 31 that is a display device such as a liquid crystal monitor of a PC is imaged by the information communication terminal 32, an authentication identifier is extracted from the graphic code, and the authentication identifier is It transmits to the authentication server 34. In response to the reception of the authentication identifier, the authentication server 34 compares the authentication identifier held by the authentication server 34 and, if they match, authenticates the connection of the information communication terminal 32 to the network 33. With this authentication, the authentication server 34 transmits the authenticated graphic code to the information communication terminal 32 and displays it on the display means of the information communication terminal 32.

  Further, along with the authentication of the information communication terminal 32, the authentication server 35 receives the authentication identifier included in the graphic code displayed on the information providing medium 31 as a display device, and the authentication identifier held by the authentication server 35 If they match, the connection of the information providing medium 31 to the network 33 is authenticated, and the information providing medium 31 is connected to the network 33. By connecting to the network 33, the authentication server 34 transmits and displays the same graphic code as the authenticated graphic code transmitted to the information communication terminal 32 to the information providing medium 31 via the authentication server 35.

  By this processing, in addition to authentication by the authentication servers 34 and 35, visual authentication can be performed by visually comparing the information providing medium 31 on which the authenticated graphic code is displayed and the information communication terminal 32. . After confirming that they are the same, an identification code can be extracted from the authenticated graphic code, and corresponding information can be obtained from the database 30 using the identification code.

  The authenticated graphic code to be transmitted to and displayed on the information communication terminal 32 and the information providing medium 31 is not limited to the same one. For example, the graphic code obtained by dividing the pictogram in half and merging the two is provided in the information providing medium 31. The graphic code in which the other is fused can be transmitted to the information communication terminal 32 and displayed. Whether the user collates the graphic code sent to his / her information communication terminal 32 with the graphic code transmitted to the information providing medium 31 and displays it, and forms one graphic code when combined. Depending on the situation, it is possible to perform visual authentication.

  Although not shown in FIG. 3, a management server for managing the database 30 can be provided, an identification code is sent to the management server, and the address of the information stored in the database 30 is acquired from the management server, and the address Information can be obtained by accessing.

  In this case, the identification code can represent the manufacturer name or product number, and the pictogram can represent the category of information provided. The management server can hold a table in which manufacturer names and product numbers are associated with addresses such as URLs corresponding thereto.

  When the graphic code shown in FIG. 1C is acquired as the authenticated graphic code, the information communication terminal 32 extracts the identification code shown in FIG. 1A from the graphic code, and uses the identification code to wash it. The video data of the egg process can be accessed and provided. In this case, it is possible to deliver an image in which eggs from a surveillance camera installed in a sorting and packaging facility have undergone an appropriate egg washing process.
