Is executed (step S62).

  Next, the non-contact reader / writer 1 acquires the redirect server URL to which the terminal unique number (“555” in the example of FIG. 9) of the non-contact reader / writer 1 is added, and the acquired MB is included in the redirect server URL. A unique number is added (step S63), and the command, the redirect server URL to which the terminal unique number and the MB unique number are added (in the example of FIG. 7, “http://aa.bb.jp/redirect/ ? tid = 555 & uid = 998877 ") is transmitted to the cellular phone 2 (step S64," (2) URL transmission "shown in FIG. 9) to prompt the non-contact IC chip to access the URL.

  When the command and the redirect server URL are thus transmitted from the non-contact reader / writer 1 to the mobile phone 2, the mobile phone 2 starts a browser and displays a screen 57 as shown in FIG. 10 on the display 22. . In such a display state, when the user of the mobile phone 2 operates the operation key 21 to select “Yes” and presses the execution key included in the operation key 21, the mobile phone 2 (browser) is redirected. The redirect server 3 is accessed via the network NW based on the server URL (step S65, “(3) access” shown in FIG. 9).

  After the session is established by the access, the redirect server 3 transmits the download server URL (FIG. 9) corresponding to the terminal unique number (“555” in the example of FIG. 9) added to the redirect server URL from the mobile phone 2. In the example of FIG. 9, “http://dlsvr1.jp/?tid= <% TID%> & uid = <% UID%>”) is obtained from the redirect destination management database 31, and the download server URL replacement character string ( <% TID%>) is replaced with the terminal unique number added to the redirect server URL, and the replacement character string (<% UID%>) of the download server URL is added to the redirect server URL. (Step S66). As a result, the terminal unique number and the MB unique number are added to the download server URL.

  Next, the redirect server 3 sends the download server URL (“http://dlsvr1.jp/?tid=555&uid=998877” in the example of FIG. 9) to which the terminal unique number and MB unique number are added to the network NW. Through the mobile phone 2 (step S67, “(5) URL reply” shown in FIG. 9).

  Here, the date and time information indicating the date and time when the mobile phone 2 has been accessed and the terminal unique number and MB unique information added to the redirect server URL are associated with each other and registered in the access log database 32 as log information. (Recording) may be configured.

  When the download server URL returned from the redirect server 3 is received by the mobile phone 2 in this way, the mobile phone 2 (browser) performs the above-described download server URL (in the example of FIG. 9, “ http://dlsvr1.jp/?tid=555&uid=998877 ”) and the download server 4y is accessed via the network NW (step S69,“ (6) access ”shown in FIG. 9).

  After the session is established by the access, the download server 4y adds the date / time information indicating the date / time (year / month / day in the example of FIG. 9) when the mobile phone 2 has accessed and the download server URL. The terminal unique number (“555” in the example of FIG. 9) and the MB unique information (“998877” in the example of FIG. 9) are associated and registered (recorded) in the access log database 42 as log information (step) S70, “(7) Log recording” shown in FIG. 9).

  Next, the download server 4y refers to the log information registered in the access log database 42 and determines whether or not two or more MB unique numbers of the mobile phone 2 are registered in the same terminal unique number. Download screen data corresponding to the determination result (that is, download screen data when there is only one MB unique number or download screen data when there are two or more MB unique numbers) is acquired from the content database 41 (step S71). The download screen data is provided (transmitted) to the mobile phone 2 via the network NW (step S72, “(8) Download screen data provision” shown in FIG. 9).

  When the download screen data provided from the download server 4y is received by the mobile phone 2, a download screen 58 as shown in FIG. 10 is displayed on the display 22. In the download screen 58, since two or more MB unique numbers of the mobile phone 2 are registered in the access log database 42 at the same terminal unique number, it is displayed that downloading is not possible. On the other hand, if only one MB unique number of the mobile phone 2 is registered in the access log database 42 with the same terminal unique number, a download screen 59 as shown in FIG. 10 is displayed on the display 22. In other words, the user can download the voice data of the incoming melody by operating the operation key 21 on the mobile phone 2.

  In the first and second embodiments, the content server 4 also associates the date and time information indicating the date and time when the mobile phone 2 has accessed, the terminal unique number and the MB unique information with the access log as log information. It may be configured to be registered (recorded) in the database 42.

[2-5. Fifth Embodiment]
Next, with reference to FIG.11 and FIG.12, operation | movement of the information provision system S which concerns on 5th Embodiment is demonstrated.

  FIG. 11 is a conceptual diagram illustrating an operation example of the information providing system S according to the fifth embodiment, and FIG. 12 is a sequence diagram illustrating processing, information flow, and the like in the information providing system S according to the fifth embodiment. is there.

  In the fifth embodiment, as shown in FIG. 11, the content server 4 is applied as an information providing server as an example, but a stamp rally server or a download server may be used.

  In the first to fourth embodiments described above, once a URL of an access destination (for example, a redirect server URL, a content server URL, etc.) by the mobile phone 2 is known by the user, the user is notified of the mobile phone. The user can access the access destination from the cellular phone 2 by directly operating the operation key 21 and directly inputting the URL of the access destination. At this time, on the accessed server side, whether the access is an access by the user bringing the mobile phone 2 close to (contacting) the non-contact reader / writer 1 or the URL of the access destination from the mobile phone 2 by the user There is a problem that it is not known whether the access is made by directly inputting.

  In order to solve this problem, in the fifth embodiment, when the contactless reader / writer 1 transmits the redirect server URL to the mobile phone 2, an authentication code is added to the direct server URL, and the authentication processing of the authentication code is redirected. The server 3 is configured to confirm that the access is an access by bringing the mobile phone 2 close to the non-contact reader / writer 1. Further, when the redirect server 3 returns the redirect destination URL to the mobile phone 2, an authentication code is added to the redirect destination URL, and the content server 4 performs the authentication code authentication process, for example, so that the access is performed. It is configured to confirm that the access is made by bringing the mobile phone 2 closer to the non-contact reader / writer 1.

  More specifically, in the ROM of the contactless reader / writer 1, in addition to the redirect server URL and the terminal unique number, an access point key unique to the contactless reader / writer 1 (an example of key data unique to the contactless reader / writer) Is stored in advance, and the contactless reader / writer 1 uses, for example, the access point key, the terminal unique number, and the MB unique number (the access point key and the terminal unique number may be used alone) as an authentication code. (First authentication code, hereinafter referred to as “APMAC (Access Point Message Authentication code)”) is generated, the APMAC is added to the redirect server URL, and the APMAC, the terminal unique number, the MB unique number, and the like are added. The redirect server URL is transmitted to the mobile phone 2.

  Here, as a calculation method for generating the APMAC, a known HMAC-SHA1 function can be used. When this function is used, APMAC is defined by the following equation (1).

APMAC = HMAC-SHA1 _Apkey (TID + UID) (1)
Here, “Apkey” represents an access point key unique to the contactless reader / writer 1, “TID” represents a terminal unique number, and “UID” represents an MB unique number. If TID = 123 and UID = 998877, then APMAC = HMAC-SHA1 _Apkey (123998877).

  On the other hand, in addition to the access log database 32, a redirect destination ID management database 31a, an access point key management database 33, and a redirect destination URL / service key management database 34 are constructed in the recording device of the redirect server 3. .

  In the redirect destination ID management database 31a, for each of a plurality of contactless reader / writers installed at various locations, a terminal unique number of the contactless reader / writer and a server ID of the redirect destination (for example, unique to the content server 4). Server ID) is registered in association with each other. In the access point key management database 33, for each of the plurality of contactless reader / writers, a terminal unique number of the contactless reader / writer and an access point key unique to the contactless reader / writer are registered in association with each other. It has become so. The redirect destination URL / service key management database 34 includes a redirect destination server ID, a redirect destination URL (for example, a content server URL), a service key unique to the content server 4 (key data unique to the information providing server). Are registered in association with each other (that is, a service key is managed for each redirected server ID and URL).

  As a result of the redirect destination ID management database 31a and the redirect destination URL / service key management database 34, as a result, the redirect destination URL and its service key are assigned the server ID of the redirect destination to the terminal unique number of the contactless reader / writer. Are associated with each other.

  When the mobile phone 2 accesses based on the redirect server URL, the control device of the redirect server 3 accesses the access point key unique to the contactless reader / writer 1 corresponding to the terminal unique number added to the redirect server URL. Is obtained from the access point key management database 33, and the APMAC authentication process added to the redirect server URL is performed using the obtained access point key or the like. In this authentication process, for example, the acquired access point key, the terminal unique number added to the redirect server URL, and the MB unique number are used. Is generated, and it is determined whether or not the generated APMAC value and the APMAC value added to the redirect server URL match. If they match, authentication is successful (authentication OK). It is determined.

  Only when the authentication can be performed in this way, the control device of the redirect server 3 displays the redirect destination URL (corresponding to the redirect destination server ID) corresponding to the terminal unique number of the non-contact reader / writer 1 as the redirect destination. Obtained from the management database 34, the URL of the redirect destination is returned to the mobile phone 2 via the network NW. At this time, the control device of the redirect server 3 acquires the server ID of the redirect destination corresponding to the terminal unique number of the contactless reader / writer 1 added to the redirect server URL from the redirect destination ID management database 31a. A service key unique to the content server 4 corresponding to the ID (in other words, the acquired URL of the redirect destination) is acquired from the redirect destination URL / service key management database 34 and added to the acquired service key and the redirect server URL. The authentication code (second authentication code, hereinafter referred to as “SMAC (Service Message Authentication code)”) is generated using the terminal unique number and the MB unique number (the service key and the terminal unique number may be used). , The redirect obtained above for the SMAC Added to the URL, the SMAC, has terminal-specific number, and MB unique number, such as additional redirect location URL (for example, the content server URL) to reply to the mobile phone 2.

  Here, as a calculation method for generating the SMAC, a known HMAC-SHA1 function can be used as in the APMAC. When this function is used, SMAC is defined by the following equation (2).

SMAC = HMAC-SHA1 _Svkey (UID + TID) (2)
Here, “Svkey” indicates a service key unique to the information providing server. When TID = 123 and UID = 998877, SMAC = HMAC-SHA1 _Svkey (99888123).

  On the other hand, in addition to the content database 41 and the access log database 42, a service key management database 43 is constructed in the recording device of the content server 4. In the service key management database 43, a service key unique to the content server 4 is registered.

  When the mobile phone 2 accesses based on the content server URL, the control device of the content server 4 acquires a service key unique to the content server 4 from the service key management database 43, and acquires the acquired service key, etc. Is used to perform the SMAC authentication process added to the content server URL. In such authentication processing, for example, the acquired service key, the terminal unique number added to the content server URL, and the MB unique number are used, and the SMAC is generated by the above equation (2) as in the redirect server 3. Then, it is determined whether or not the generated SMAC value matches the SMAC value added to the content server URL. If they match, it is determined that the authentication is successful (authentication OK). . Only when the authentication can be performed in this way, the control device of the content server 4 provides advertisement information to the mobile phone 2, for example.

  Hereinafter, a more detailed operation in the fifth embodiment will be described.

  In FIG. 12, when the user of the mobile phone 2 brings the mobile phone 2 close to the lighting panel 11 in the non-contact reader / writer 1, the non-contact reader / writer 1 detects the mobile phone 2 as in the first embodiment (step S81), mutual authentication (the non-contact reader / writer 1 reads the MB unique number (“998877” in the example of FIG. 11)) from the mobile phone 2 (“(1) Read MB unique number” shown in FIG. 11)) Is executed (step S82).

  Next, the contactless reader / writer 1 reads the access point key and the terminal unique number from the ROM, and uses the access point key and the terminal unique number and the MB unique number acquired from the mobile phone 2, as described above, Generate (Step S83, “(2) APMAC generation” shown in FIG. 11).

  Next, the non-contact reader / writer 1 acquires the redirect server URL to which the above-described terminal unique number is added, and adds the acquired MB unique number and the generated APMAC to the redirect server URL (step S84, FIG. 11). "(3) Add APMAC etc."), the above command, and the redirect server URL to which the terminal unique number, MB unique number and APMAC are added (in the example of FIG. 11, "http://aa.bb.jp / redirect /? tid = 123 & uid = 998877 & apmac = d8fc65b4 ") to the mobile phone 2 (step S85," (4) URL transmission "shown in FIG. 11) to access the URL to the non-contact IC chip. Prompt.

  When the command and the redirect server URL are thus transmitted from the non-contact reader / writer 1 to the mobile phone 2, the mobile phone 2 activates a browser and displays a screen 61 as shown in FIG. 12 on the display 22. . In such a display state, when the user of the mobile phone 2 operates the operation key 21 to select “Yes” and presses the execution key included in the operation key 21, the mobile phone 2 (browser) is redirected. The redirect server 3 is accessed via the network NW based on the server URL (step S86, “(5) access” shown in FIG. 11).

  After the session is established by the access, the redirect server 3 uses the access point key management database 33 for the access point key (Apkey1) unique to the contactless reader / writer 1 corresponding to the terminal unique number added to the redirect server URL. As described above, the APMAC authentication process added to the redirect server URL is performed using the acquired access point key or the like (step S87, “(6) authentication process” shown in FIG. 11). .

  When the authentication can be performed by the APMAC authentication process (authentication OK), the redirect server 3 redirects the redirect destination URL (for example, the content server) corresponding to the terminal unique number of the contactless reader / writer 1 added to the redirect server URL. URL) from the redirect destination URL / service key management database 34, a service key (Svkey1) specific to the content server 4 corresponding to the obtained redirect destination URL is obtained from the redirect destination URL / service key management database 34, As described above, an SMAC is generated using the acquired service key, the terminal unique number added to the redirect server URL, and the MB unique number (step S88, “(7) SMAC creation shown in FIG. 11). ").

  Note that if the authentication can be performed by the APMAC authentication process (authentication OK), the redirect server 3 displays the date and time information indicating the date and time when the mobile phone 2 has accessed and the contactless reader / writer 1 added to the redirect server URL. The terminal unique number and the APMAC may be associated with each other and registered (recorded) in the access log database 32 as log information.

  Next, the redirect server 3 adds the terminal unique number, MB unique number, and the generated SMAC to the obtained redirect destination URL (for example, content server URL) (step S89, “(8) shown in FIG. 11). SMAC etc. addition ").

  Next, the redirect server 3 returns the redirect destination URL to which the terminal unique number, MB unique number, SMAC, etc. are added to the mobile phone 2 (step S90, “(9) URL reply” shown in FIG. 11).

  When the redirect destination URL returned from the redirect server 3 is received by the mobile phone 2, the mobile phone 2 (browser) automatically (that is, does not require user operation) redirect (step S91) processing. Thus, the content server 4 is accessed via the network NW based on the redirect destination URL (step S92, “(10) access” shown in FIG. 11).

  Then, after the session is established by the access, the content server 4 acquires the service key (Svkey1) from the service key management database 43, and uses the acquired service key and the like as described above, Authentication processing of the SMAC added to the URL is performed (step S93, “(11) authentication processing” shown in FIG. 11).

  If the authentication process is successful (authentication OK), the content server 4 acquires, for example, advertisement information from the content database 41 (step S94) and provides the information to the mobile phone 2 via the network NW. (Send) (Step S95, “(12) Information provision” shown in FIG. 11).

  If the authentication can be performed by the SMAC authentication process (authentication OK), the redirect server 3 displays the date and time information indicating the date and time when the mobile phone 2 has accessed and the contactless reader / writer added to the redirect destination URL. The terminal unique number 1 and the SMAC may be associated with each other and registered (recorded) in the access log database 42 as log information.

  As described above, according to the fifth embodiment, when the contactless reader / writer 1 transmits the redirect server URL to the mobile phone 2, the APMAC is added to the redirect server URL, and the APMAC authentication process is redirected. The server 3 can confirm that the access is an access by bringing the mobile phone 2 closer to the non-contact reader / writer 1, and the redirect server 3 redirects the redirect destination URL to the mobile phone 2. By adding SMAC to the previous URL and performing the SMAC authentication processing, for example, by the content server 4, it is possible to confirm that the access is an access by bringing the mobile phone 2 closer to the non-contact reader / writer 1. . Thereby, for example, in the fifth embodiment, only a case where the mobile phone 2 is tricked into the non-contact reader / writer 1 and the present application site can be accessed at the last base or customers who come to the venue. It is more effective for the case where the special discount shopping site can be accessed.

  In addition, the redirect server 3 is configured to generate an SMAC instead of the APMAC after the authentication of the APMAC added to the direct server URL and add it to the redirect destination URL (generates an authentication code in two stages). Therefore, more efficient system operation can be achieved. That is, the business operator that operates the content data 4 (or stamp rally server or download server) may be different from the business operator that operates the non-contact reader / writer 1 and the redirect server 3. This is because it is difficult to store the access point key unique to the corresponding contactless reader / writer 1 but it is easy to store the service key unique to the content data 4 in each content data 4. However, the APMAC may be added to the redirect destination URL without generating the SMAC. In this case, it is necessary to store an access point key unique to the corresponding contactless reader / writer 1 for each content data 4.

  In the above embodiment, the APMAC and SMAC are calculated using a known HMAC-SHA1 function. As another example, the contactless reader / writer 1 has a terminal unique number and an MB unique number. The APMAC is generated by encrypting the terminal unique number and the MB unique number (or any other information) with the access point key, and the redirect server 3 decrypts the APMAC with the access point key (SMAC In this case, the redirect server 3 encrypts the terminal unique number and the MB unique number with the service key to generate an SMAC, and the content server 4 performs authentication (authentication OK when decrypted). You may comprise. In this case, only the APMAC (or SMAC) needs to be added to the redirect server URL (or the redirect destination URL) (the terminal unique number and the MB unique number do not need to be added) and are registered on the redirect server 3 side. For example, when a plurality of access point keys are used one by one in the order of registration and decryption is attempted and decryption is performed, a terminal unique number corresponding to the decrypted (authenticated) access point key is identified, and the terminal unique number The SMAC is generated by acquiring the service key associated with the terminal, the redirect destination URL associated with the terminal unique number is acquired, and the redirect destination URL to which the generated SMAC is added is the mobile phone 2. Will reply to.

  In the above embodiment, the redirect server 3 further includes a mobile phone manufacturing number management database in which the manufacturing number of the mobile phone 2 and the MB unique number are registered in association with each other, and the mobile phone 2 uses the redirect server URL. When accessing based on the mobile phone manufacturing number management database, the redirect server 3 refers to the association between the serial number of the mobile phone 2 that can be acquired at that time and the terminal unique number added to the redirect server URL. If it is configured to execute the subsequent processing (for example, the processing after step S87) only when the association is correct, for example, the redirect server URL to which the APMAC is added is transmitted to the other mobile phone. Even when it is transferred, unauthorized access can be detected.
