Description

The present invention relates to an information providing system using code information.

イ ン タ ー ネ ッ ト With the development of communication technology, network technology and computer technology, the Internet, which is a representative of interactive media, is shifting from narrowband to broadband.

In Japan, the Internet function has been added to mobile phones, so there are overwhelmingly many Internet users (so-called browser phone users) using mobile phones compared to Internet users who mainly use PCs in Europe and the United States.

Many users who use such a browser phone enjoy e-mail on a mobile phone or access a web page compatible with the browser phone to obtain information.
Regarding such a browser phone, for example, Patent Document 1 discloses a web site using a browser phone without a new WEB area hosting service contract and without an environment such as a PC or construction software or knowledge. We provide mobile phone system technology that can be easily constructed. This is because the HP creation assistance server provides an HP creation screen for access from a browser phone, has a function of constructing an HP directory file based on information input from the HP creation screen, and uploading the created HP directory file to a web server. The server has a function of receiving an upload from the HP creation assistance server and posting an HP directory file in a WEB area for a browser phone.

By the way, the web address of the content provider is registered in the official menu of the service of the carrier by the certification of the mobile phone company (so-called carrier). In this case, by accessing specific content along the menu registered by the carrier, it is possible to access the web page.

However, in order to be registered as a career, there is a fairly high hurdle screening, and not everyone is registered. Therefore, a content provider who is not registered transmits information by using a unique URL. This is called a selfish site.

On the other hand, in the case of a browser phone user, when such a content provider uses a unique URL, the content provider accesses the URL by keying in the URL, or selects and accesses the URL given to the e-mail (web). to).
JP-A-2003-122675

However, the operation of inputting and selecting such a URL is complicated. Therefore, as a method of making more browser phone users easily access information, for example, there is a number code access using toll-free telephone. This is a method in which Internet address information is converted into specific numeric information, and an Internet number, a kanji URL, and the like are used. However, in this method, the numbers that can be used do not always match the numbers and kanji of the people who want to use them, and it is considered that there is still room for improvement in that sense.

問題 The problem to be solved is that the operation of inputting and selecting a URL is complicated, and it is not possible to easily and reliably realize the attraction to interactive media.

(First Embodiment)
FIG. 1 is a diagram showing a first embodiment of an information providing system using code information of the present invention, and FIG. 2 is a diagram for explaining an information providing method in the information providing system using code information of FIG. It is a flowchart.

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 but may be a dedicated line or the like.

The code issuing 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 issuing management server 11. The code issuance management server 11 manages two-dimensional code information issued in response to a request from an advertiser, and decodes two-dimensional code information used on the mobile phone 30 side. And so on.

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 an advertiser server 21. The advertiser server 21 provides various information in response to access from the mobile phone 30 using the two-dimensional code information.

Here, the issued two-dimensional code information can be distributed, for example, by being printed on a distribution material. Examples of the distributed materials include newspapers, magazines, advertisements, company brochures, insert flyers, OOH (Out of Home) media, POPs, tickets, tickets, business cards, tags, and the like.

By printing the two-dimensional code information on these handouts, it is possible not only to guide the user from the mobile phone 30 to the advertising campaign site, but also to reserve and settle various tickets (or settle), sell products, and settle accounts. (Or settlement) service, TV program reservation service, development in B2B business, etc. can be realized.

In addition, by printing the two-dimensional code information on the distribution in this way, as described above, the registration of the web address by the authorization of the mobile phone company (so-called carrier) becomes unnecessary, so that any business format can be used. It provides an environment that is easy for companies to participate and that encourages new business creation. That is, there are two types of services currently provided by carriers, namely, official sites and unofficial sites (so-called selfish sites). 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.

By the way, the dial Q2 of the paid service implemented by the telephone company is also a service development in which content holders and service destinations are similarly bundled. This is to prevent the telephone company's communication line from being used without permission. Therefore, services (customs) that the telephone company does not like can be interrupted by the telephone company without permission.

一方 で On the other hand, the Internet does not do such a thing, and the website is determined 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. One of the methods is to obtain service information from the paper medium and jump to the service site based on cooperation with the paper medium. It will be determined whether or not to do so. Since these services are not controlled by the carrier but are operated by a trust relationship between the caller and the user, as a result, companies of any business type can participate.

Further, for a browser phone user using the mobile phone 30, access by inputting a URL, access by selecting a URL given to an e-mail (web @ to), and replacement of information with a number or a kanji are used for information. Access by entering a specific page is not required.

The mobile phone 30 as a mobile terminal has a photographing function using a camera equipped with a CCD which is an image pickup device, and includes a CCD reading unit 31, a decoding unit 32, a browser phone function unit 33, and a storage unit. 34 and a control unit 35.

The CCD reading section 31 reads image information captured by a CCD camera. Here, as the image information, any of a still image and a moving image may be used as long as the image information can be captured by the image sensor. In the present embodiment, for example, a QR code 51 as two-dimensional code information printed on a printed material 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.

The decoding unit 32 decodes the QR code 51 read by the CCD reading unit 31. When decoding the QR code 51, a JAVA (registered trademark) application which is decoding software is used. The JAVA (registered trademark) application can be downloaded by accessing the code issuance management server 11. The downloaded JAVA (registered trademark) application is stored in the storage unit 34.

The browser phone function unit 33 as a browsing function unit accesses a 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 in, for example, a packet. Then, the detailed information is displayed on the screen of the mobile phone 30. The browser phone function unit 33 downloads a JAVA (registered trademark) application.

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.

Next, an information providing method in the information providing system using the two-dimensional code information having such a configuration will be described.

First, as shown in FIG. 2, when a CCD camera of the mobile phone 30 captures, for example, a QR code 51 as two-dimensional code information printed on a printed matter 50 such as a magazine (step 201), the CCD reading unit. The photographed QR code 51 is read by 31 (step 202).

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 decoding of the QR code 51 is performed by calling the JAVA (registered trademark) application which is the decoding software for decoding the QR code 51 from the storage unit 34, and the decoding of the QR code 51 is performed. If it is determined that the JAVA (registered trademark) application is not stored in the server 34 (step 204), the browser phone function unit 33 accesses the code issuance management server 11 according to an instruction from the control unit 35, and the JAVA (registered trademark) (Trademark) application is downloaded (step 205). The downloaded JAVA (registered trademark) application is stored in the storage unit 34 (step 206).

When the JAVA (registered trademark) application is obtained in this manner, 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, in a packet (step 210), the detailed information is displayed on the screen of the mobile phone 30 (step 211).

As described above, in the first embodiment, the code issuing server system 10 issues two-dimensional code information in response to a request via the Internet 40, and the advertiser server system 20 issues the two-dimensional code information. The two-dimensional code information is received via the Internet 40, and the received two-dimensional code information is managed by the advertiser server 21, and the two-dimensional code information is obtained by the mobile phone 30 having a photographing function using a CCD camera. The information is photographed, a web address included in the photographed two-dimensional code information is acquired, a web page is accessed via the Internet 40 using the acquired web address, and the advertiser server system 20 The information is transmitted to the mobile phone 30 via the Internet 4 in response to the access from the mobile phone 30. It was to be provided through the.

As a result, even if the content provider does not register his or her web address in the menu of the service of the carrier due to the authorization of the mobile phone company (so-called carrier) as in the related art, the content provider issues the 2 The dimension code information can be printed and distributed on the above-mentioned advertisements, company brochures, insert flyers, OOH media, POP, tickets, tickets, business cards, tags, etc. Therefore, it is possible to easily realize the attraction to the interactive media.

On the other hand, many browser phone users who use the mobile phone 30 take the two-dimensional code information printed on the distribution with a CCD camera mounted on the mobile phone 30 to obtain a desired web page. Since the access can be made, it is not necessary to input the original URL of the content provider as in the related art, and the access to the interactive media can be executed extremely easily and reliably.

(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 and 5 show the operation of the information providing system using the code information of FIG. FIG. In the drawings described below, the same parts as those in FIG.

In the information providing system using the two-dimensional code information shown in FIG. 3, for example, an advertiser server system 20 includes a public key management server 22 and a secret key management server 23.

The public key management server 22 manages a public key as two-dimensional code information, for example, for decoding an encrypted part of the QR code 51. The public key will be described later. The secret key management server 23 manages a secret key used when generating an encrypted part of the QR code 51 issued on the code issuing server system 10 side.

Here, the QR code 51 issued on the code issuing server system 10 side has a public part and an encrypted part as shown in FIG. 4, for example. The public part of the QR code 51 includes, for example, public information such as its own IP address on the advertiser server system 20 side. The encrypted part of the QR code 51 includes necessary information such as an encrypted web address. When the encrypted part of the QR code 51 is generated, the above-mentioned secret key is used. The encrypted portion of the QR code 51 may have tag information such as CGI (Common Gateway Interface). In this case, the advertiser server system 20 can perform the process according to the request from the web, and can provide the information by the process to the mobile phone 30 side.

Here, the URL information that the user wants the user to jump to is converted into a sequence and encoded into the QR code 51. Two types of information are converted as information for converting the URL information. One is a service destination management IP address in the public part. The other is necessary information of the encrypted part. Specifically, “when a certain distribution destination provides a service of its own content on its own site using mobile EC”, a service destination management IP address (public part: 23476887) that accumulates information of this service, The address of the mobile EC site that implements the service is “www.m-service.com/mec/index.thml”. In this example, the mobile phone 30 decodes the service management IP address “23476887” and the CGI tag information from the QR code information.

Next, the process jumps to the service management IP address “23476887”. Here, the secret key is received and obtained, and the address “www.m-service.com/mec/index.thml” of the mobile EC site that implements the service is obtained, and the process jumps to the service destination.

Next, an information providing method in the information providing system using the two-dimensional code information having such a configuration will be described.

First, as shown in FIG. 5, when a QR code 51 is issued on the code issuing server system 10 side, for example, in response to a request from an advertiser, a secret key from the secret key management server 23 is received (step 501). . By using this secret key, an encrypted part is generated by encrypting a part of the character string of the QR code 51 (step 502). By generating the encrypted part, the QR code 51 having the public part and the encrypted part is issued (step 503). The issued QR code 51 is printed on a printed material 50 such as a magazine and widely distributed.

On the other hand, when the QR code 51 printed on the printed matter 50 such as a magazine is photographed by the CCD camera of the mobile phone 30 (step 504), the photographed QR code 51 is read by the CCD reading unit 31 (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 decoding of the QR code 51 is executed. If the trademark (registered trademark) application is not stored (step 507), as described above, the JAVA (registered trademark) application is downloaded by accessing the code issuance management server 11 (step 508). The downloaded JAVA (registered trademark) application is stored in the storage unit 34 (step 509).

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, for example, the own IP address of the advertiser server system 20 side shown in FIG. 4 is obtained by decoding the QR code 51 (step 511), and the browser phone function unit 33 uses the electronic mail based on the IP address. Transmission by e-mail is performed (step 512).

At this time, in response to the response from the secret key management server 23 of the advertiser server system 20, an e-mail attached with the secret key is returned to the accessed mobile phone 30 (step 513).

When the mobile phone 30 receives the secret key, the encrypted portion of the QR code 51 shown in FIG. 4 is decoded by the JAVA (registered trademark) application stored in the storage unit 34 (step 514). Here, when a web address is obtained from the encrypted portion by decoding (step 515), the browser phone function unit 33 accesses a web page based on the web address (step 516). Then, when the detailed information from the access destination is received, for example, in a packet (step 517), the detailed information is displayed on the screen of the mobile phone 30 (step 518).

As described above, in the second embodiment, the public part and the encrypted part are provided in the two-dimensional code information, and the decoding of the encrypted part is performed by the advertiser server system 20 that has requested the issuance of the two-dimensional code information. Is provided by the secret key obtained from the secret key management server 23, and the provision of various information from the advertiser server system 20 is reliably performed to the mobile phone 30 accessed based on the IP address of the public part. Is

Further, since various information is provided only to the accessed mobile phone 30, not only the management of the accessed mobile phone 30 is facilitated, but also the security is easily constructed, and the unauthorized use of the mobile phone 30 is facilitated. Exclusion can also be easily achieved.

In the second embodiment, a case has been described where the decoding of the encrypted portion on the mobile phone 30 side is performed using the secret key obtained from the secret key management server 23. However, the present invention is not limited to this example. When an electronic mail is transmitted from the mobile phone 30 based on the IP address, the encrypted part is attached to the electronic mail, and the encrypted part is decoded from the secret key management server 23. Information may be returned to the mobile phone 30 side.

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. However, the present invention is not limited to this example, and cgi, SSI, ASP, etc. may be described in the encrypted part. Tag can also be described. In this case, these tags not only make it possible to widen the variations of various information provided from the advertiser server system 20, but also facilitate participation of companies of any business type and encourage new business creation. An easy environment can be provided.

In the second embodiment, the expiration date of the code itself can be set by setting the expiration date information of the secret key in the secret key management server 23, for example, so that it is posted in the back number of a magazine, for example. The validity period can be easily restricted for access from the code information and application access to the prize. In addition, if code information linked to content that is against public order and morals is released, or if code information issued by any illegal procedure is released, the secret key corresponding to that information will be released. Can be prevented or misused on the side of the secret key management server 23 to prevent unauthorized use. In each of the above embodiments, a case has been described where the two-dimensional code information is a QR code. However, the present invention is not limited to this example, and other codes having information in two-dimensional directions such as horizontal and vertical directions may be used. it can.

Further, in each of the above embodiments, the case where two-dimensional code information is photographed by the mobile phone 30 having a photographing function using a CCD camera has been described. However, the present invention is not limited to this example. As described above, the mobile phone 30 may have a function of decoding the code information wirelessly. In this case, it is not necessary to mount the CCD camera on the mobile phone 30.

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. However, the present invention is not limited to this example, and as shown in FIG. May be added.

In other words, as shown in FIG. 6A, the bitmap information can be added as an icon 51a for explaining the contents of the application. In this case, the mobile phone 30 reads information such as the Web address and the mail address, which are the contents of the QR code 51, and also reads the bitmap information.
