In a redirect service, when there is an access to the reduced URL shown by the two-dimensional code 24 which is generated in a two-dimensional code generation service, the access is redirected to an URL of a connected party stored in association with the random number. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a communication server having a redirect (transfer) function and a code generation server that generates a color code.

  Conventionally, codes representing arbitrary data and optically readable have been used in various fields. For example, codes having information only in one direction, such as barcodes, are widely used due to the speed and accuracy of reading. On the other hand, since the need for a code capable of storing more information in a smaller space is increasing, a two-dimensional code having information in a two-dimensional direction has been rapidly spread in recent years.

  There are various types of two-dimensional codes, for example, a stack type two-dimensional code and a matrix type two-dimensional code. Stacked two-dimensional code is a code that represents information by stacking one-dimensional barcodes finely, and matrix-type two-dimensional code is a code that represents information by arranging black and white grids (cells). . For example, as a matrix type two-dimensional code, at least two predetermined positions in the matrix in a two-dimensional code in which data represented by a binary code is cellized and arranged as a pattern on a two-dimensional matrix In addition, there is known a two-dimensional code in which positioning symbols having a pattern in which the same frequency component ratio can be obtained in scanning lines that cross the center at all angles (see, for example, Patent Document 1).

  In recent years, codes that represent arbitrary information in a color or shade arrangement have also been proposed.

Many of these codes represent URLs (Uniform Resource Locators) that specify the location (address) of information on the Internet. Just by reading the code with a terminal such as a mobile phone equipped with a function for reading the code, A location indicated by the read URL can be accessed by a predetermined application.
Japanese Patent No. 2938338

  However, the conventional two-dimensional code is generally expressed in black and white, there is no color variation, and even if it is a code that represents arbitrary information with a color arrangement, the expression method is not limited. It is one and cannot have any characteristics.

  The present invention has been made in order to solve the above-described problems. A communication server that can be easily connected to a connection destination based on read information obtained by reading a color code, and a color combined with a pictogram. It is an object of the present invention to provide a code generation server that can easily generate code.

  In order to achieve the above object, the communication server of the present invention comprises a receiving means for receiving read information obtained by reading a color code representing connection destination information and identification information of the own device, the identification information, A connection destination storage unit that stores the connection destination information other than the own device in association with each other, and a connection destination stored in the connection destination storage unit in correspondence with the identification information included in the read information received by the reception unit And connecting means for connecting via a network to the connection destination indicated by the information.

  In this communication server, identification information and connection destination information other than its own device (communication server) are stored in advance in the connection destination storage means. Further, the communication server receives the read information obtained by reading the color code representing the connection destination information and identification information of the own device, and corresponds to the connection information corresponding to the identification information included in the received read information. Connect to the connection destination indicated by the connection destination information stored in the storage means via the network.

  For example, a terminal that can read a code accesses the communication server using the connection destination information obtained by reading the code and corresponds to the identification information obtained by reading the code through the communication server. The connection destination stored in the connection destination storage means can be connected.

  Thus, according to the communication server of the present invention, it is possible to easily connect to a connection destination corresponding to the identification information included in the read information obtained by reading the color code.

The connection destination information of the own device may be a URL or a shortened URL of the own device, and the connection destination information other than the own device stored in the connection destination storage unit may be a URL other than the own device.
The shortened URL is a URL with a reduced number of digits, and can be used, for example, by acquiring and registering a short domain with a domain acquisition service or the like. If the shortened URL of the own device is represented by a code, the code can be a small size.

  Further, the code according to the present invention represents the connection destination information and the identification information of the device in any one of a gray array, a multi-color array, a dark cell and a light cell array, and a barcode array. Code.

  Furthermore, the read information can be information obtained by reading a code displayed so as to be located in a pictogram having an area larger than the code.

  A pictogram is a pictogram or character. Thus, by displaying the code so as to be located in the pictogram, the method for expressing the code becomes richer.

  The communication server has a larger area than the code and the color code representing the connection destination information and the identification information of the own device based on the code color, background color, and pictogram type specified by the client. And generating means for combining the pictogram and generating an image displayed so that the code is positioned in the pictogram.

  For example, when generating a code represented by an array of dark cells and light cells, dark cells are generated with the specified code color and light cells with the specified background color, and the code is included in the specified pictogram. You may make it arrange | position so that it may be located. Also, the color of the pictogram can be the same color as the background color of the code. In addition, even if the code to be generated is not a code represented by an array of shaded cells in this way, it is generated using the specified code color and background color and displayed so that it is located within the specified pictogram can do.

  In this way, by generating a code based on the specified code color, background color, and pictogram type, the code expression method becomes richer.

  Further, the communication server can be designated according to a combination of storage means storing a plurality of code colors, a plurality of background colors, and a plurality of pictogram data, and a combination of each data stored in the storage means. Display control means for displaying a combination of code color, background color, and pictogram type on the display means of the client can be further included.

  That is, since a combination of code color, background color, and pictogram type that can be specified is displayed on the display means of the client, the client (user) who has viewed the display means can easily select the code color and background color. A pictogram can be specified. In the storage means, for example, the code color and the background color can be stored in correspondence with each other so that they are not the same color, and the displayable pictogram is stored in correspondence with the background color. It can also be left. The background color may be white or a color other than white.

  Note that a combination of a code color and a background color having a density contrast of a predetermined value or more can be stored in the storage unit.

  Thereby, the code can be expressed clearly, and the information of the generated code can be read accurately and easily. Note that the density contrast may be a density difference between the two or a density ratio.

  The communication server further includes a random number generation unit that generates a random number, and the generation unit can generate the identification information based on the random number generated by the random number generation unit.

  Thereby, identification information can be generated efficiently. The identification information may be the generated random number itself.

  The cord may be a square two-dimensional cord having a side of 7 mm or more.

  As described above, the connection destination storage means stores the identification information and the connection destination information other than the own device (communication server) in association with each other. Therefore, when it is desired to represent connection destination information other than the communication server with a code, the identification information stored correspondingly may be represented in the code instead of the connection destination information. Thereby, even when the connection destination information other than the communication server has a long number of digits (a large amount of information), the amount of information represented in the code can be reduced.

  In addition, the code generation server of the present invention includes a receiving unit that receives designation information designating a code color, a background color, and a pictogram type, and a code color, a background color, and a pictogram type received by the receiving unit. Based on the designation information, a color code representing connection destination information and identification information of a predetermined device and a pictogram having an area larger than the code are synthesized and displayed so that the code is located in the pictogram. And generating means for generating an image.

  In this way, by generating the code based on the designation information of the code color, background color, and pictogram type, the code can be expressed in various colors and can be combined with the pictogram. , The way of expression becomes richer. The information represented by the code is connection destination information and identification information of a predetermined device. Further, the predetermined device may be its own device (code generation server), or may be another device that performs a predetermined process according to a reading result obtained by reading a code.

  The connection destination information of the predetermined device can be a URL or a shortened URL of the predetermined device. If the shortened URL of the own device is represented by a code, the code can be a small size.

  The generated code may be a code representing the connection destination information and the identification information in any one of a gray array, a multi-color array, a dark cell and a light cell array, and a barcode array. it can.

  In addition, the code generation server can be specified according to a combination of storage means storing a plurality of code colors, a plurality of background colors, and a plurality of pictogram data, and a combination of the data stored in the storage means. Display control means for displaying a combination of various code colors, background colors, and pictogram types on the display means of the client.

  That is, since a combination of code color, background color, and pictogram type that can be specified is displayed on the display means of the client, the client (user) who has viewed the display means can easily select the code color and background color. A pictogram can be specified. In the storage means, for example, the code color and the background color can be stored in correspondence with each other so that they are not the same color, and the displayable pictogram is stored in correspondence with the background color. It can also be left.

  Note that a combination of a code color and a background color having a density contrast of a predetermined value or more can be stored in the storage unit.

  Thereby, the code can be expressed clearly, and the information of the generated code can be read accurately and easily. Note that the density contrast may be a density difference between the two or a density ratio.

  The code generation server further includes a random number generation unit that generates a random number, and an information storage unit that stores the identification information and arbitrary information in association with each other. The generation unit is generated by the random number generation unit. The identification information can be generated based on the generated random number.

  Thereby, identification information can be generated efficiently. The identification information may be the generated random number itself. The information storage means can store the identification information and arbitrary information in association with each other. The data stored in the information storage means is the connection destination indicated by the connection destination information represented by the code. By supplying to a predetermined device, for example, a terminal that can read a code can access the predetermined device by connection destination information obtained by reading the code. , Some processing can be performed on the accessed terminal using arbitrary information stored corresponding to the identification information included in the read information. Arbitrary information is not particularly limited. For example, when arbitrary information is used as corporate advertising information, the advertising information may be displayed on a terminal that has accessed the information. If arbitrary information is the URL of the connection destination, the accessed terminal can be transferred to the URL and connected. The predetermined device may be the own device (code generation server).

  Moreover, the code generation server can generate a square-shaped small two-dimensional code having a side of 7 mm or more. As described above, the information storage means stores the identification information and arbitrary information in association with each other. Therefore, when it is desired to represent arbitrary information by the code, the identification information stored correspondingly may be represented by the code instead of the arbitrary information. Thereby, even if the arbitrary information has a long number of digits (a large amount of information), the amount of information represented in the code can be reduced.

  As described above, according to the communication server of the present invention, it is possible to easily connect to the connection destination by the read information obtained by reading the color code. Further, according to the code generation server of the present invention, it is possible to easily generate a color code that can easily generate a color code combined with a pictogram.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, a two-dimensional code in which dark cells and light cells are arranged in a matrix will be described as an example.

  As shown in FIG. 1, the two-dimensional code service system of the present embodiment displays a server 10 that provides a service (two-dimensional code service) related to the two-dimensional code 24, a company homepage (HP) 40, and the like. Information such as an HTML (HyperText Markup Language) document or image is stored, and the image stored on the HP 40 is transmitted to the client's Web by transmitting the stored information via the network 16 such as the Internet in response to a request from the client. A corporate Web server 12 to be displayed on a browser, and a personal computer (PC) 14 that can be connected to the server 10 or the server 12 via a network 16 are connected devices such as a modem, a router, or a TA (terminal adapter). Connected to a network 16 such as the Internet. It is configured.

  Furthermore, a transmission / reception center 18 is connected to the network 16 via a network such as a digital cellular phone network, and a base station 20 having an antenna is connected to the transmission / reception center 18. A mobile phone 22 equipped with a data transmission / reception function and a camera 22 </ b> F that reads the two-dimensional code 24 can be connected to the network 16 via the base station 20.

  Here, as shown in FIGS. 1 and 4, the two-dimensional code 24 is a mark representing arbitrary information by arranging a plurality of dark cells and light cells in a matrix. A margin 28 having a predetermined size is provided around the two-dimensional code 24 in order to accurately read information represented in the two-dimensional code 24. In this embodiment, as shown in FIGS. 4 and 5, a color two-dimensional code 24 and a color pictogram (character or pictograph) 26 are synthesized by a two-dimensional code generation service, which will be described later. Image data in a state where 24 is located in the pictogram 26 is supplied to the user. As shown in FIG. 4, the pictogram 26 has a larger area than the two-dimensional code 24 including the margin 28, and the two-dimensional code 24 is arranged so that the margin 28 is ensured.

  As shown in FIG. 2, the server 10 that provides the two-dimensional code service includes a CPU (central processing unit) 10A that controls the entire server in accordance with the processing routines shown in FIGS. 8 and 9, and a program for this processing routine. A memory 10B having a ROM storing a RAM and a RAM 10B used as a work area, a hard disk drive, etc., and storing a plurality of code colors, a plurality of background colors, and a plurality of pictogram data in combination. A database 10C that stores the random number generated when creating the dimension code 24 and the URL of the connection destination input by the user when receiving the request for generating the two-dimensional code 24, and the input / output for inputting / outputting data A port 10D is provided. The CPU 10A, memory 10B, database 10C, and input / output port 10D are connected to each other via a bus such as a data bus or a control bus.

  Here, an outline of the two-dimensional code service provided by the server 10 will be described. The two-dimensional code service includes a two-dimensional code generation service and a redirect service.

  The two-dimensional code generation service is a service that generates a two-dimensional code 24 in response to a request from a user via the network 16. In the present embodiment, as information represented by the two-dimensional code 24, a URL (Uniform Resource Locator) used in a network such as the Internet will be described as an example. In addition, when the server 10 generates the two-dimensional code 24, the data of the connection destination URL (for example, see FIG. 6A) designated by the user when the two-dimensional code 24 is generated is used as the address of the server 10. Is converted into data composed of a shortened URL indicating ID and a random number as identification information (for identifying the URL of the connection destination designated by the user) (see, for example, FIG. 6B), and the converted data Is generated. A random number is generated for each two-dimensional code generation request, and the URL of the connection destination designated by the user at the time of the two-dimensional code generation request is stored in the database 10C in association with the generated random number (for example, see FIG. 7). ).

  Here, the shortened URL is a URL with a reduced number of digits, and can be used by acquiring and registering a short domain with a predetermined domain acquisition service or the like.

  In the two-dimensional code generation service, the dark cell color and the light cell color of the two-dimensional code 24 can be arbitrarily designated from predetermined colors. As shown in FIGS. 4 and 5, the generated two-dimensional code 24 can be superimposed on various pictograms (characters and pictograms) 26 and the two-dimensional code 24 can be arranged in the pictogram 26. The color of the pictogram 26 is the same color as the light cell color of the two-dimensional code 24.

  The redirect service refers to an access to the shortened URL indicated by the two-dimensional code 24 generated by the two-dimensional code generation service (that is, access to the own device) by referring to the database 10C and the original URL (database specified by the user). This is a service that redirects (transfers) to the URL of the connection destination stored in 10C. With this service, the mobile phone 22 that has read the two-dimensional code 24 generated by the server 10 can access the URL of the connection destination stored in the database 10C corresponding to the random number indicated by the two-dimensional code 24. .

  The input / output port 10D is connected to the network 16 via a communication control unit 10E for communicating with other devices via the network.

  The server 10 also has a function as a Web server. Specifically, data such as HTML documents and images are stored in the database 10C and the like, and these are stored via the network 16 in response to a request from a client (here, the PC 14) by a Web browser or the like. Send information, run programs on demand, and send results to clients.

  Although the configuration of the Web server 12 is substantially the same as the configuration of the server 10, illustration thereof is omitted, but the CPU and various programs for operating the CPU (files are transmitted in response to requests from the Web browser or the like). (Including software and the like) including a ROM and a work memory, and a hard disk drive for storing various data such as HTML documents and images. Further, like the server 10, the Web server 12 includes an input / output port connected to a CPU, a memory, and a hard disk drive, and a communication control unit connected to the input / output port.

  The configuration of the PC 14 as a client is substantially the same as that of the server 10 and is not shown, but stores a CPU and various programs (including client software such as a Web browser) for operating the CPU. It includes a memory composed of a ROM and work memory, a hard disk drive for storing various data, and a user interface (UI) such as a display means such as a display and an operation input means such as a keyboard and a mouse. The PC 14 further includes an input / output port connected to the CPU, memory, and hard disk drive, and a communication control unit connected to the input / output port.

  Furthermore, as shown in FIG. 3, the mobile phone 22 used by the user includes software such as a web browser, software that reads the two-dimensional code 24 and accesses the URL represented by the two-dimensional code 24, and the like. Memory 22A stored, CPU 22B that performs processing according to software stored in memory 22A, transmitter / receiver 22C that transmits and receives data, LCD display 22D that displays information, key operation unit 22E that includes a confirmation key, a numeric keypad, etc. A camera 22F is provided for photographing the two-dimensional code 24 and reading the data represented by the two-dimensional code 24.

  Hereinafter, the processing routine of the two-dimensional code generation service executed by the CPU 10 of the server 10 according to the present embodiment will be described with reference to FIG. This processing routine is started when accessed from the Web browser of the PC 14.

  In step 100, data for displaying the initial screen on the Web browser of the PC 14 is transmitted, and the initial screen is displayed on the Web browser of the PC 14. Although illustration of the initial screen is omitted, the user of the PC 14 can input a URL to be expressed by a two-dimensional code from the initial screen.

  In step 102, input of URL is waited. Here, when the URL input by the user is received, the process proceeds to step 104. In step 104, a random number 32B having a predetermined number of digits (6 digits in FIGS. 4 and 5) is generated, and as shown in FIG. 7, a table in which the generated random number 32B is associated with the input URL 30 is created. And stored in the database 10C.

  In step 106, data for displaying a list of selectable two-dimensional code colors (code colors) on the Web browser of the PC 14 is transmitted, and the list is displayed on the Web browser of the PC 14. The Code color displayed here is a color stored in advance in the database 10C. Since the Code color is used as a dark cell color of the two-dimensional code, for example, a high-density color that is easy to read the two-dimensional code 24 can be obtained. The user of the PC 14 can select and specify a desired color from the displayed list. The color designated here is set as the color of the dark cell of the generated two-dimensional code 24.

  In step 108, the selection of the Code color is awaited. Here, when the Code color selected by the user is received, the process proceeds to Step 110. In step 110, a list of selectable background colors is displayed on the web browser of the PC. The background color is a light cell color of the two-dimensional code 24 and is used as a color of the pictogram 26 superimposed on the two-dimensional code 24. In the database 10C, a background color having a density lower than the Code color and having a density contrast with the Code color of a predetermined value or more, for example, a background color having a density contrast ratio of 55% or more, Are stored for each code color. Here, the background colors stored in combination with the selected and specified code color among the background colors stored in the database 10C are displayed in a list on the Web browser. The user of the PC 14 can select and specify a desired background color from the displayed list.

  Note that the generated two-dimensional code 24 can be easily read by setting the density contrast between the Code color and the background color stored in combination to a predetermined value or more.

  In step 112, the selection of the background color is waited. Here, when the background color selected by the user is received, the process proceeds to step 114. In step 114, a list of selectable sizes of the two-dimensional code 24 is displayed on the Web browser of the PC. The user of the PC 14 can select a desired size from the displayed list. In the present embodiment, as will be described later, since the two-dimensional code 24 is generated so that the data constituted by the shortened URL and the random number is represented by the two-dimensional code 24 instead of the long URL input by the user, The amount of data represented by the two-dimensional code 24 can be reduced, and the two-dimensional code 24 can be generated with a minimum of 7 mm square. Therefore, here, a size of 7 mm square or more can be displayed as a list.

  In step 116, the selection of the size is awaited. Here, when the background color selected by the user is received, the process proceeds to step 118. In step 118, a list of selectable pictograms 26 is displayed on the Web browser of the PC 14. A plurality of selectable pictograms 26 are stored in the database 10C in combination with the selected code color and background color, and names indicating the stored pictograms 26 are displayed in a list. The pictogram is not particularly limited, and may be, for example, a polygonal pictogram 26 as shown in FIG. 4 or a star-shaped pictogram 26 as shown in FIG. In this embodiment, when white is selected as the background color, the background color “white” and the pictogram are selected so that only “square” for securing the margin of the two-dimensional code 24 is selected. “Square” is combined and stored in the database 10C. The display method is not particularly limited. For example, a list of pictogram names that can identify the pictogram 26 may be displayed, or a picture of the pictogram 26 may be displayed. The user of the PC 14 can select a desired pictogram 26 from the displayed list.

  In step 120, selection of the pictogram 26 is awaited. Here, when the information of the pictogram 26 selected by the user is received, the process proceeds to step 122. In step 122, a two-dimensional code 24 is generated. Specifically, with the dark cell color set to the selected code color and the light cell color set to the selected background color, the shortened URL 32A indicating the address of the server 10 as shown in FIG. 6B. And two-dimensional code image data representing the data 32 composed of the random number 32B. In step 124, as shown in FIG. 5, the two-dimensional code 24 is arranged at a coordinate position determined in advance so that the two-dimensional code 24 is arranged in the pictogram 26 having a size corresponding to the selected size. Thus, the two-dimensional code 24 and the pictogram 26 are synthesized. The predetermined coordinate position is a coordinate position where the two-dimensional code 24 is arranged in the pictogram 26 so as to ensure the margin 28.

  In step 126, a preview image of the image data obtained by combining is displayed on the Web browser of the PC. The user can see this preview image and determine whether to download or cancel the generated image data of the two-dimensional code 24. If the user requests download from the Web browser at step 128, the image data is downloaded to the user's PC 14 at step 130. If the user cancels the downloading of the image data in step 128, the processing routine is terminated without performing the processing of step 130. At the time of cancellation, the record stored in association with the corresponding random number and URL in the database 10C may be deleted.

  The downloaded image data can be used as appropriate by the user. For example, the downloaded image data may be printed on a business card or postcard, or the image data may be printed on a sticker and pasted on various media.

  Next, the flow of processing when the image of the two-dimensional code 24 is read by the mobile phone 22 will be described.

  When the camera mode of the mobile phone 22 is activated and the camera 22F is pointed at the two-dimensional code 24 and the confirmation key provided in the key operation unit 22E of the mobile phone 22 is turned on, the photographing operation is started and the memory 22A The processing routine program stored in is started. By this processing routine program, the URL 32A of the server 10 represented by the image of the two-dimensional code 24 read by the camera 22F can be automatically accessed.

  In the server 10, when accessed from the mobile phone 22, a redirect service processing routine program shown in FIG. 9 is started.

  In step 200, the URL 30 stored in the database 10C is retrieved corresponding to the 6-digit random number 32B designated immediately below the URL 32A of the server 10 as the read result of the two-dimensional code 24. If the search fails here, an error may be returned. Furthermore, an error can be returned by setting a time limit for using this service and deleting the corresponding random number 32B and URL 30 from the database 10C so that the service cannot be used after the time limit has passed.

  In step 202, image data of a coupon for receiving a specific service is transmitted to the accessed mobile phone 22 (issue coupon). This coupon may be a coupon of a company selected at random from all companies participating in the two-dimensional code service provided by the server 10 in advance, or may be a coupon of a company of the searched URL 30. The user of the mobile phone 22 can display a coupon image based on the received image data, and can receive various services using the coupon.

  In step 204, the retrieved URL 30 is redirected (transferred) so that the mobile phone 22 that has accessed the server 10 is connected to the retrieved URL 30.

  As described above, since the shade color of the two-dimensional code can be arbitrarily specified, the two-dimensional code can be individually designed. Furthermore, since the two-dimensional code is synthesized with the pictogram, there are many ways to express it. In addition, since the URL specified by the user is stored in correspondence with the random number (identification information) and the data composed of the shortened URL and the random number is represented by the two-dimensional code, the size of the two-dimensional code is reduced. be able to. Further, since the random number represented in the two-dimensional code is redirected to the original URL, even if the two-dimensional code has a small size, the desired URL can be accessed by reading the two-dimensional code.

  In the above embodiment, the coupon is issued when the redirect service is performed. However, this allows a specific coupon to be issued easily, and the issuing company manages the information, thereby making it more active. Sales activities.

  In the above embodiment, the example in which the two-dimensional code generation service and the redirect service are performed by the same server has been described. However, the present invention is not limited to this, and each service may be performed by different servers. In this case, the server that performs the two-dimensional code generation service transfers a table that associates the random number generated by the two-dimensional code generation and the URL specified by the user to the server that performs the redirect service. There is a need.

  In the above-described embodiment, an example in which a mobile phone is used as a terminal device that reads a two-dimensional code has been described. However, the present invention is not limited to a mobile phone, and has a function of reading a two-dimensional code by connecting a personal computer and a scanner. A terminal device may be used.

  In the above embodiment, a two-dimensional code representing data composed of the shortened URL of the server 10 and identification information (random number) associated with the connection destination URL has been described as an example. The associated information is not limited to the connection destination URL, and can be arbitrary information. For example, it may be an email address. In this case as well, as described above, the destination of the mail address can be stored in correspondence with the random number, and the shortened URL and the random number data can be expressed by a two-dimensional code as described above. Further, by storing the random number and the original mail address in association with each other, it is possible to transfer the mail in the same manner as in the above embodiment. Information represented by a two-dimensional code may be used as a corporate advertisement message. In this case, the advertisement message is stored in association with the random number, and the stored advertisement message is distributed when accessed.

  A normal URL may be used instead of the shortened URL included in the data represented by the two-dimensional code.

  In the above embodiment, the description has been given by taking as an example a two-dimensional code in which dark cells and light cells are arranged in a matrix. However, the present invention is not limited to this, and for example, a light and dark array or a color array. May be a code representing data, or a code representing data in an array of barcodes such as a stack type two-dimensional barcode.
