Information providing system using code information

[0001] [Technical field to which the invention belongs] The present invention relates to an information providing system using code information. [0002] [Conventional technology] With the development of communication technology and network technology and the progress of computer technology, the Internet, which is a representative of interactive media, is about to shift from narrow band to broadband. [0003] In Japan, the addition of Internet functions to mobile phones has led to an overwhelming majority of Internet users (so-called browser phone users) on mobile phones compared to Internet users centered on Western PCs. [0004] Many users of such browser phones enjoy e-mail on their mobile phones and access web pages compatible with browser phones to obtain information. [0005] [Problems to be Solved by the Invention] By the way, the web address of the content provider is registered in the official menu of the carrier's service by the certification of the mobile phone company (so-called carrier). In this case, the web page can be accessed by accessing the specific content according to the menu registered by the carrier. [0006] However, in order to be registered as a career, there are quite high hurdles to be examined, and not everyone is registered. Therefore, content providers who are not registered use their own URLs to send information. This is a so-called selfish site. [0007] On the other hand, for browser phone users, when such a content provider uses its own URL, it is accessed by keying in the URL or by selecting the URL given to the e-mail (web). Either method of to) is taken. [0008] However, the operation of inputting and selecting such a URL is complicated. Therefore, as a method for allowing more browser phone users to easily access information, for example, there is a number code access that applies a toll-free number of a telephone. This is a method of converting Internet address information into specific numerical information, and Internet numbers, Kanji URLs, and the like have come to be used. However, in this method, the number that can be used and the number and feeling of the person who wants to use it do not always match, and in that sense, it is considered that there is still room for improvement. [0009] The present invention has been made in view of such a situation, and provides an information providing system using code information that can easily and surely realize attraction to interactive media by using code information. It allows you to do it. [0010] [Means for solving problems] The information providing system using the code information of the present invention is<u style="single">Image information is captured by a server that manages the private key used when decrypting the encrypted part included in the code information and a capture function using an imaging element, and the captured image information is decoded by the decoding unit. By doing so, a public part included in the code information expressed as image information and a mobile terminal that acquires an encrypted part and accesses the server via a network using the access information indicated by the public part. The server transmits the private key to the accessed mobile terminal using the access information, and the mobile terminal that receives the secret key decodes the encrypted portion using the private key. Obtain information on the new access destination and access the new access destination</u>It is characterized by that. [0011] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described. [0012] (First Embodiment) FIG. 1 is a diagram showing a first embodiment of an information providing system using the code information of the present invention, and FIG. 2 is a diagram for explaining an information providing method in the information providing system using the code information of FIG. It is a flowchart. [0013] The information providing system using the code information shown in FIG. 1 includes a code issuing server system 10, an advertiser server system 20, and a mobile phone 30. The code issuing server system 10, the advertiser server system 20, and the mobile phone 30 can communicate with each other via the Internet 40 as a network. Here, the network is not limited to the Internet 40, and may be a dedicated line or the like. [0014] The code issuance server system 10 issues, for example, two-dimensional code information as code information in response to a request from an advertiser, and includes a code issuance management server 11. The code issuance management server 11 manages the 2D code information issued in response to a request from the advertiser, and is a JAVA (registered trademark) application for decoding the 2D code information used on the mobile phone 30 side. Is provided. [0015] The advertiser server system 20 as the information providing server system manages the two-dimensional code information issued by the code issuing server system 10, and includes the advertiser server 21. The advertiser server 21 provides various types of information according to access using the two-dimensional code information from the mobile phone 30. [0016] Here, the issued two-dimensional code information can be printed and distributed on, for example, a distribution. Distributions include newspapers, magazines, advertisements, in-house pamphlets, leaflets, OOH (Out Of Home) media, POPs, tickets, tickets, business cards, tags, etc. [0017] By printing the two-dimensional code information on these distributions, it is possible not only to guide the user from the mobile phone 30 to the advertising campaign site, but also to make various ticket reservations / settlement (or settlement), product sales, and settlement. (Or payment) service, TV program reservation service, development in B2B business, etc. can be realized. [0018] In addition, by printing the two-dimensional code information on the distribution in this way, as described above, it is not necessary to register the web address certified by the mobile phone company (so-called carrier). An environment is provided that makes it easy for companies to participate and encourages the creation of new businesses. In other words, there are two types of services currently provided by carriers: official websites and unofficial websites (so-called selfish websites). Originally, there is no problem if all contents and services are official websites, but it is difficult for carriers to authenticate and it takes time to make all official websites. [0019] By the way, dial Q2, a paid service implemented by a telephone company, is also a service development that bundles content holders and service destinations. This is to prevent the communication line of the telephone company from being used without permission. Therefore, for services (customs) that the telephone company does not like, it is possible for the telephone company to suspend the service without permission. [0020] On the other hand, the Internet does not do such a thing, and the judgment of the website is made by the free transaction between the caller and the user. In this case, it is premised that the user enjoys the service while making a certain judgment, and one of the methods is to obtain the service information from the paper media and jump to the service site based on the cooperation with the paper media. It will be decided whether or not to do so. These services are not controlled by the carrier and are operated by the relationship of trust between the caller and the user, and as a result, any type of company can participate. [0021] [0021] In addition, for browser phone users who use mobile phone 30, access by entering the URL and access by selecting the URL given to the e-mail (web) to), it is replaced with numbers and kanji, and access by entering information on a specific page is no longer necessary. [0022] The mobile phone 30 as a mobile terminal has a shooting function using a camera equipped with a CCD, which is an image sensor, and has a CCD reading unit 31, a decoding unit 32, a browser phone function unit 33, and a storage unit. It has 34 and a control unit 35. [0023] The CCD reading unit 31 reads the image information taken by the CCD camera. Here, the image information may be either a still image or a moving image as long as it can be photographed by the image sensor. In the present embodiment, for example, a QR code 51 as two-dimensional code information printed on a printed matter 50 such as a magazine is extracted and read. The QR code 51 read by the CCD reading unit 31 is temporarily stored in the storage unit 34. [0024] The decoding unit 32 decodes the QR code 51 read by the CCD reading unit 31. When decoding the QR code 51, the JAVA (registered trademark) application, which is decoding software, is used. This JAVA® application can be downloaded by accessing the code issuance management server 11. The downloaded JAVA® application is stored in the storage unit 34. [0025] The browser phone function unit 33 as the browsing function unit accesses the web page based on the web address decoded by the decoding unit 32 according to a predetermined control program, and receives detailed information from the access destination, for example, in a packet. And, the detailed information is displayed on the screen of the mobile phone 30. In addition, the browser phone function unit 33 downloads the JAVA (registered trademark) application. [0026] The storage unit 34 stores the QR code 51 read by the CCD reading unit 31, the downloaded JAVA (registered trademark) application, and the like. The control unit 35 controls the operation of each unit according to a predetermined control program. [0027] Next, an information providing method in an information providing system using the two-dimensional code information having such a configuration will be described. [0028] First, as shown in FIG. 2, when a QR code 51 as two-dimensional code information printed on a printed matter 50 such as a magazine is photographed by the CCD camera of the mobile phone 30 (step 201), the CCD reader The photographed QR code 51 is read by 31 (step 202). [0029] The QR code 51 read by the CCD reading unit 31 is temporarily stored in the storage unit 34 (step 203). When the QR code 51 is stored in the storage unit 34, the decoding unit 32 decodes the QR code 51. At this time, the JAVA (registered trademark) application, which is decoding software for decoding the QR code 51, is called from the storage unit 34 to execute the decoding of the QR code 51. The storage unit 35 controls the storage unit 35. When it is determined that the JAVA (registered trademark) application is not stored in 34 (step 204), the browser phone function unit 33 accesses the code issuance management server 11 according to the instruction from the control unit 35, thereby performing JAVA (registration). A trademark) application is downloaded (step 205). The downloaded JAVA® application is stored in storage 34 (step 206). [0030] When the JAVA® application is obtained in this way, the QR code 51 is decoded by the decoding unit 32 (step 207). At this time, since the web address is obtained by decoding the QR code 51 (step 208), the browser phone function unit 33 accesses the web page based on the web address (step 209). Then, when the detailed information from the access destination is received, for example, by a packet (step 210), the detailed information is displayed on the screen of the mobile phone 30 (step 211). [0031] As described above, in the first embodiment, the code issuing server system 10 issues the two-dimensional code information in response to the request via the Internet 40, and the advertiser server system 20 issues 2 The two-dimensional code information is received via the Internet 40, and the two-dimensional code information received is managed by the advertiser server 21 and is managed by the mobile phone 30 having a shooting function using a CCD camera. As the information is captured, the web address included in the captured two-dimensional code information is acquired, and the acquired web address is used to access the web page via the Internet 40, and the advertiser server system 20 uses the acquired web address. , Information is provided to the mobile phone 30 via the Internet 40 in response to the access from the mobile phone 30. [0032] As a result, as in the past, the content provider was issued by the code issuing server system 10 even if his / her web address was not registered in the carrier's service menu by the certification of the mobile phone company (so-called carrier) 2 Since the dimension code information can be printed and distributed on the above-mentioned advertisements, in-house pamphlets, insert leaflets, OOH media, POP, tickets, tickets, business cards, tags, etc., it can be distributed to many browser phone users. , Attracting to interactive media can be easily realized. [0033] On the other hand, many browser phone users who use the mobile phone 30 can take the two-dimensional code information printed on the distribution with the CCD camera mounted on the mobile phone 30 to access the desired web page. Since the access can be performed, it is not necessary to enter the original URL of the content provider as in the conventional case, and the access to the interactive media can be executed extremely easily and surely. [0034] (Second embodiment) FIG. 3 is a diagram showing a second embodiment in which the configuration of the information providing system using the code information of FIG. 1 is changed, and FIGS. 4 to 5 are operations of the information providing system using the code information of FIG. It is a figure for demonstrating. In the figures described below, the same parts as those in FIG. 1 are designated by the same reference numerals, and duplicate description will be omitted. [0035] In the information providing system using the two-dimensional code information shown in FIG. 3, for example, the advertiser server system 20 is provided with a public key management server 22 and a private key management server 23. [0036] The public key management server 22 manages a public key for decoding the encrypted part of, for example, the QR code 51 as two-dimensional code information, and the public key will be described later. The private key management server 23 manages the private key used when generating the encrypted part of the QR code 51 issued by the code issuing server system 10. [0037] Here, the QR code 51 issued on the code issuing server system 10 side is provided with a public part and an encrypted part, for example, as shown in FIG. The public part of the QR code 51 includes public information such as the own IP address of the advertiser server system 20 side. In addition, the encrypted part of the QR code 51 contains necessary information such as an encrypted web address. The above private key is used to generate the encrypted part of the QR code 51. The encrypted part of the QR code 51 can also have tag information such as CGI (Common Gateway Interface). In this case, the advertiser server system 20 can perform processing in response to a request from the web, and can provide information on the processing to the mobile phone 30 side. [0038] Here, the URL information that the user wants to jump to is converted into a sequence and encoded in the QR code 51. Two types of information are converted as information when converting URL information. One is the service destination management IP address of the public part. The other is the necessary information for the encrypted part. Specifically, "when a certain distribution destination provides its own content on its own site with mobile EC service", the service destination management IP address (public part: 23476987) that collects information on this service, The address of the mobile EC site that provides the service is "www.m-service.com/mec/index.thml". In this example, the service destination management IP address "23476987" and the CGI tag information are decoded in the mobile phone 30 from the QR code information. [0039] Next, jump to the service destination management IP address "23476987". Here, the private key is received and obtained, the address "www.m-service.com/mec/index.thml" of the mobile EC site that provides the service is obtained, and the service destination is jumped to. [0040] Next, an information providing method in an information providing system using the two-dimensional code information having such a configuration will be described. [0041] First, as shown in FIG. 5, for example, when the QR code 51 is issued on the code issuing server system 10 side in response to a request from the advertiser, the private key from the private key management server 23 is received (step 501). .. By using this private key, an encrypted part in which a part of the character string of QR code 51 is encrypted is generated (step 502). When the encrypted part is generated, a QR code 51 having a public part and an encrypted part is issued (step 503). The issued QR code 51 is printed on printed matter 50 such as magazines and widely distributed. [0042] On the other hand, when the CCD camera of the mobile phone 30 captures the QR code 51 printed on the printed matter 50 such as a magazine (step 504), the CCD reader 31 reads the captured QR code 51 (step 504). 505). The QR code 51 read by the CCD reading unit 31 is temporarily stored in the storage unit 34 (step 506). When the QR code 51 is stored in the storage unit 34, the decoding unit 32 decodes the QR code 51. At this time, when the JAVA (registered trademark) application, which is decoding software for decoding the QR code 51, is called from the storage unit 34, the QR code 51 is decoded, but JAVA (registered) is executed in the storage unit 34. If the trademark) application is not stored (step 507), the JAVA® application is downloaded by accessing the code issuance management server 11 as described above (step 508). The downloaded JAVA® application is stored in storage 34 (step 509). [0043] When the JAVA (registered trademark) application is obtained in this way, the public part of the QR code 51 is decoded by the decoding unit 32 (step 510). At this time, since the own IP address of the advertiser server system 20 side shown in FIG. 4, for example, can be obtained by decoding the QR code 51 (step 511), the browser phone function unit 33 obtains the electronic address based on the IP address. It will be sent by email (step 512). [0044] At this time, the response of the private key management server 23 of the advertiser server system 20 returns an e-mail with the private key attached to the accessed mobile phone 30 (step 513). [0045] When the mobile phone 30 receives the private key, the JAVA (registered trademark) application stored in the storage unit 34 decodes the encrypted part of the QR code 51 shown in FIG. 4 (step 514). Here, when a web address is obtained by decoding from the encrypted part (step 515), the browser phone function unit 33 accesses the web page based on the web address (step 516). Then, when the detailed information from the access destination is received, for example, by a packet (step 517), the detailed information is displayed on the screen of the mobile phone 30 (step 518). [0046] As described above, in the second embodiment, the public part and the encrypted part are provided in the two-dimensional code information, and the decryption of the encrypted part is performed on the advertiser server system 20 side that requested the issuance of the two-dimensional code information. Since it is performed by the private key obtained from the private key management server 23 of the above, various information is surely provided from the advertiser server system 20 to the accessed mobile phone 30 based on the IP address of the public part. It is said. [0047] In addition, since various information is provided only to the accessed mobile phone 30, not only is it easy to manage the accessed mobile phone 30, but it is also easy to build security, and it is also illegally used. Elimination can also be easily achieved. [0048] In the second embodiment, the case where the decoding of the encrypted part on the mobile phone 30 side is performed by the private key obtained from the private key management server 23 has been described, but the present invention is not limited to this example. , When the mobile phone 30 side sends an e-mail based on the IP address, the encrypted part is attached to the e-mail, and the encrypted part is decoded from the private key management server 23. It is also possible to send the information back to the mobile phone 30 side. [0049] Further, in the second embodiment, the case where the web address is described in the encrypted part of the two-dimensional code information has been described, but not limited to this example, cgi, SSI, ASP, etc. are described in the encrypted part. You can also write the tag of. In this case, these tags not only make it possible to expand the variation of various information provided by the advertiser server system 20, but also make it easier for companies of any business type to participate and encourage the creation of new businesses. It is possible to provide an easy environment. [0050] Further, in the second embodiment, for example, by setting the valid date and time information of the private key in the private key management server 23, the expiration date of the code itself can be set, so that the code itself is posted on the back number of a magazine, for example. It is possible to easily limit the validity period for access from the code information and application access for prizes. In addition, if the code information associated with content that is offensive to public order and morals is released, or if the code information issued by some fraudulent procedure is released, the private key corresponding to that information is released. It is also possible to prevent unauthorized use by disabling or destroying the information on the private key management server 23 side. In each of the above embodiments, the case where the two-dimensional code information is a QR code has been described, but the present invention is not limited to this example, and other codes having information in the two-dimensional directions in the horizontal and vertical directions can be used. it can. [0051] Further, in each of the above embodiments, a case where two-dimensional code information is photographed by a mobile phone 30 having a photographing function using a CCD camera has been described, but the present invention is not limited to this example, and Bluetooth and the like have been described. It is also possible to give the mobile phone 30 a function of wirelessly decoding the code information. In this case, it is not necessary to mount the CCD camera on the mobile phone 30. [0052] Further, in each of the above embodiments, the case where a single QR code 51 is used as the two-dimensional code information has been described, but the present invention is not limited to this example, and as shown in FIG. 6, the bitmap information is used in the QR code 51. Can also be added. [0053] That is, as shown in FIG. 6A, bitmap information can be added as an icon 51a for explaining the contents of the application. In this case, the information such as the Web address and the e-mail address, which is the content of the QR code 51, is read into the mobile phone 30, and the bitmap information is also read. When referring to the information of the contents of QR code 51 on the operation screen of the mobile phone 30, it is possible to visually show the contents by also displaying the bitmap information of the read icon 51a. it can. [0054] Further, as shown in FIG. 6B, bitmap information can be added as a rectangular image 51b. The rectangular image 51b shows a consortium of companies A and B. In this case, the shape of the rectangular image 51b can be used as the authentication key, and access to the consortium of companies A and B is prevented unless the shape of the rectangular image 51b is specified. It can be done and it will be effective in terms of security. [0055] Further, as shown in FIG. 6 (c), bitmap information can be added as an application switching image 51c. That is, by using the application switching image 51c as, for example, a memo paper icon, a business card icon, an inventory icon, etc., the application such as memo information software, business card information software, inventory software, etc., which is activated by the QR code 51, is switched. be able to. [0056] As shown in FIG. 6 (d), another barcode 51d can be added as the bitmap information. Apart from the QR code 51, the information of this barcode 51d can be read, and the operation of the application at the time of reading the QR code 51 or after reading can be changed based on this information. For example, you can change the confirmation sound when reading the QR code 51. This barcode 51d may be a QR code. [0057] Further, as shown in FIG. 6 (e), the bitmap information can be added as the extended QR code 51e. In this case, the QR code 51 can have the information of the advertisement itself, and the extended QR code 51e can have the information of the printed matter on which the advertisement is placed. By dividing the information into the QR code 51 and the extended QR code 51e in this way, it is possible to increase the reading speed of the QR code 51 or the extended QR code 51e even when the amount of information is large. It becomes. [0058] [0058] Further, as shown in FIG. 7, the function of each bitmap information can be switched by changing the color of the rectangular line 51f surrounding the QR code 51. In addition, the area of bitmap information associated with the QR code 51 is clearly indicated by a graphic 51f such as a rectangular line that surrounds or surrounds the QR code 51, and the color or shape of the graphic 51f, or both. It is also possible to switch the function of each bitmap information by changing. [0059] As a specific example of providing information in the present embodiment, there is, for example, "music audition service using a mobile phone". This is because when the QR code 51 printed next to the new music information introduced in the music section of the town information magazine is photographed with the mobile phone 30, the captured QR code 51 is decoded inside the mobile phone 30, for example, service access. Obtain the number "45984521", access the information providing server "45984521", receive the private key, and access the music audition service destination. When you access the music audition service, the music you want to audition flows from the server to the mobile phone 30. [0060] In addition, for example, there is a "ticket purchase service using mobile commerce". For example, if you take a picture of the QR code 51 printed in the advertisement to reserve a ticket for the theater introduced in the advertisement section of the newspaper with the mobile phone 30, the QR code 51 taken in the mobile phone 30 will be decoded. For example, it is a service that obtains the service access number "12345678", accesses the information providing server "12345678", receives the private key, and accesses the ticket reservation service destination. In addition, when accessing the ticket reservation service, the desired ticket reservation can be made with the mobile phone 30 by inputting the desired date information and the like. [0061] Further, in each of the above embodiments, the case where the decoding unit 32 on the mobile phone 30 side executes the decoding of the QR code 51 has been described, but the present invention is not limited to this example, and the QR code 51 to be decoded is not limited to this example. For example, it is possible to send the information to the code issuing server system 10 and receive the information of the QR code 51 decoded by the code issuing server system 10. In this case, the decoding unit 32 is not required on the mobile phone 30 side. [0062] [Effect of the invention] According to the information providing system using the code information according to the present invention as described above, the code issuing server system issues the code information in response to the request via the network, and the information providing server system issues the code information. The code information is received via the network, the received code information is managed, and the code information is taken by a mobile terminal having a shooting function using an imaging element, and the shot code is taken. The web address included in the information is acquired, the web page is accessed via the network using the acquired web address, and the information is networked to the mobile terminal according to the access from the mobile terminal by the information providing server system. Since it is provided via the code information, it is possible to easily and surely realize the attraction to the interactive media.
