Description

  The present invention relates to a packet signal relay device, a packet signal relay method, a packet signal relay program, an information selection system, and information for selecting information to be acquired by a user, such as content provided by a content server on the Internet. It relates to a sorting method.

  Not only the Internet but also various information sources such as a content server are connected to various communication networks, and the user can access information such as content information. Information such as content information may include services and advertisements.

  For example, taking the Internet as an example, a user can access various information sources on the web using an information processing device such as a personal computer or a mobile phone. However, some of these information sources may contain content information that is harmful to minor users. When a minor accesses carelessly, the harmful content information is processed by the information processing apparatus for the minor. There is a risk of being sent to and viewed. In addition, there may be a female-only banner ad that is unnecessary for male users on the homepage, and if this is mistakenly clicked on the information processing device, the male user can obtain unnecessary information for economic or time. Wasteful generation of waste.

  For this reason, for example, an Internet service provider used by a user to connect to the Internet obtains information for restricting access to content by conducting a questionnaire or making a self-report to the user. In other words, the superiority or inferiority of information presented to the user when a plurality of contents are acquired has been performed. However, if the user submits the document by a method such as a questionnaire, there are users who do not submit and users who do not provide sufficient answers, and it is difficult to effectively limit the content. There was a problem. Furthermore, depending on the user, the contents of the questionnaire and self-reports are often incorrect, making it difficult to obtain highly reliable information.

  Therefore, it may be possible to present a copy of the ID card or the Internet service provider itself to create a credit card for the user. It is necessary to consider the user's resistance to the issuance of credit cards, which is difficult to realize.

Therefore, the content distribution server allows the user to register various types of user information including date of birth, sex, etc., and retrieves content information suitable for the user information from the internal content information and displays it on the user's screen. It has been proposed as a related art of the invention (see, for example, Patent Document 1 and Patent Document 2).
JP 2002-207767 (paragraphs 0006 and 0024, FIG. 2) Japanese Patent Laying-Open No. 2005-332048 (paragraphs 0006 and 0024, FIG. 2)

  <First Embodiment of the Invention>

  Next, a first embodiment of the present invention will be described.

  FIG. 6 shows an outline of the configuration of the content selection system according to the embodiment of the present invention. A content selection system 100 according to this embodiment includes a user terminal 101 used by a user, an Internet service provider device 102 managed by an Internet service provider (ISP) as an Internet connection provider, and various types of devices on the Internet. The content service provider device 103 is managed by a content service provider (CSP) serving as an information service provider. In the content selection system 100 according to the present embodiment, content information that is most suitable for the user is supplied from the content service provider apparatus 103 to the user terminal 101.

  For this reason, in the content selection system 100 of the present embodiment, an IPv6 extension header defining user information such as age and gender is added to the user's IPv6 (Internet Protocol Version 6) packet and transmitted to the content service provider apparatus 103. I am doing so. The content service provider apparatus 103 analyzes the IPv6 extension header of the IPv6 packet sent via the Internet service provider apparatus 102 and provides the user with the optimum content information (service, advertisement, etc.). Yes.

  In such a content selection system 100, it is necessary to create an IPv6 extension header for each user. A process for this will be described first. The user terminal 101 is provided with a user ID (identifier) and password from the Internet service provider apparatus 102 when making a new contract with the Internet service provider. Further, the user presents user information such as age, sex, and job type to the Internet service provider apparatus 102. The Internet service provider apparatus 102 stores the user information in the user contract information table 111, and stores the user ID and password and the IPv6 address used by the user in the user access table 112. .

  When using the Internet, the user uses the login dedicated tool 121 to connect to the Internet service provider apparatus 102, inputs the user ID and password, and sends them to the packet of the Internet service provider apparatus 102 from the packet transmission unit 122. Send to the receiver 113 and log in. The user ID and password at this time are presented from the Internet service provider apparatus 102 at the time of the user contract.

  The Internet service provider apparatus 102 records the IPv6 address used by the logged-in user in the user access table 112 together with the user ID. Next, the Internet service provider apparatus 102 uses the IPv6 extension header creation unit 114 to determine the user information based on the user information such as age, gender, job type, the user ID and the IPv6 address described in the user access table 112. An IPv6 extension header defining the above is created. The IPv6 extension header is stored in the IPv6 extension header table 115. In this way, the preparation on the Internet service provider apparatus 102 side when the user terminal 101 uses the content service provider apparatus 103 is completed.

  Thereafter, a case where the user acquires content information from the content service provider apparatus 103 using the user terminal 101 will be described. A user data request 123 is transmitted as an IPv6 packet from the packet transmission unit 122 of the user terminal 101 to the content service provider apparatus 103 as a destination. In the Internet service provider apparatus 102, the packet receiving unit 113 receives this IPv6 packet.

  The packet receiving unit 113 sends the received IPv6 packet to the IPv6 extension header adding unit 116. The IPv6 extension header adding unit 116 checks the IPv6 address in the IPv6 extension header table 115 using the source IPv6 address of the received IPv6 packet. Thus, the IPv6 extension header adding unit 116 acquires IPv6 extension header information corresponding to the source IPv6 address. The IPv6 extension header adding unit 116 adds this IPv6 extension header information to the received IPv6 packet. The IPv6 packet to which the IPv6 extension header information is added is transmitted to the content service provider apparatus 103 by the packet transmission unit 117.

  In the content service provider apparatus 103, the packet receiving unit 131 receives this IPv6 packet and sends it to the IPv6 extension header analyzing unit 132. The IPv6 extension header analysis unit 132 analyzes the IPv6 extension header of the sent IPv6 packet and acquires user information of the accessing user. As a result, the IPv6 extension header analysis unit 132 selects content information from the data storage unit 133 in a form that matches information such as the user's age, sex, and job type, and sends the content information to the packet transmission unit 134.

  This selection of content information is applied not only to providing information for a service requested by a user but also to an accompanying advertisement. For example, when a user who has requested provision of content information is found to be a minor from the user information, content information that is harmful to minors is excluded and provided as content information suitable for minors.

  The IPv6 packet transmitted from the packet transmission unit 134 is received by the packet reception unit 118 in the Internet service provider apparatus 102 and transmitted from the packet transmission unit 119 to the user terminal 101. In the user terminal 101, the packet reception unit 124 receives this and sends it to the data expansion unit 125. The data expansion unit 125 expands the content information sent from the content service provider apparatus 103.

  As described above, according to the content selection system 100 of the embodiment of the present invention, the Internet service provider apparatus 102 performs user information registration and subsequent changes by a contract with the user. The content service provider apparatus 103 simply uses the user information created or changed in this way, and cannot change this user information. Also, the user himself cannot directly create or add user information. Therefore, in this embodiment, there is no possibility that user information is generated by impersonating the user or the user information is changed by a third party.

  Next, a first embodiment of the present invention will be described.

  FIG. 7 shows the configuration of the content selection system according to the first embodiment of the present invention. In this content selection system 200, a line 202 laid in a user's house 201 is connected to the Internet 204 via a predetermined Internet service provider device 203. As an example, a content service provider device 205 for providing content information is connected to the Internet 204.

  The line 202 drawn into the user's home 201 is connected to a first user terminal 211 and a second user terminal 212 that constitute a home LAN (Local Area Network) via a line terminating device and a router (not shown). . Here, the first user terminal 211 is a terminal such as a personal computer personally used by the user A, and the second user terminal 212 is a terminal such as a personal computer personally used by the user B. Each of the first and second user terminals 211 and 212 is an information processing apparatus including a CPU (Central Processing Unit) (not shown) and a memory (not shown) that stores a control program executed by the CPU.

  These first and second user terminals 211 and 212 incorporate the login dedicated tools 213 and 214 as a part of the control program described above. Therefore, the user A can connect to the Internet 204 by inputting the dedicated login information provided from the Internet service provider apparatus 203 to the first user terminal 211 using the login dedicated tool 213. User B can also connect to the Internet 204 by inputting the dedicated login information provided from the Internet service provider device 203 into the second user terminal 212 using the login dedicated tool 214.

  Similar to the first or second user terminals 211 and 212, the Internet service provider apparatus 203 is an information processing apparatus that includes a CPU (not shown) and a memory (not shown) that stores a control program executed by the CPU. . The Internet service provider apparatus 203 includes a user access table 221 used for user access, a user contract information table 222 storing user information, IPv6, in addition to circuit parts such as a communication control unit for packet transmission / reception control (not shown). An IPv6 extension header creation unit 223 that creates an extension header, an IPv6 extension header table 224 that associates an IPv6 address with user information, and an IPv6 extension header addition unit 225 that adds an IPv6 extension header to a packet are provided.

  The content service provider device 205 is also an information processing device that includes a CPU (not shown) and a memory (not shown) that stores a control program executed by the CPU. The content service provider apparatus 205 includes an IPv6 extension header analysis unit 231 that analyzes an IPv6 extension header and a data storage unit 232 in which content information is stored, in addition to a circuit unit such as a communication control unit for packet transmission / reception (not shown). I have.

  FIG. 8 shows the contents recorded in the user access table at a predetermined time. Assume that the user A logs in from the first user terminal 211 shown in FIG. 7 at a predetermined time point, and the user B logs in from the second user terminal 212 at another time point thereafter. The user access table 221 records the IPv6 addresses of these users A and B. Here, it is assumed that one user ID “123456” is the ID of the user A, and the other user ID “789902” is the ID of the user B. The user access table 221 also records the access times of the users A and B up to the present time.

  FIG. 9 shows the contents of the user contract information table in the first embodiment. The user contract information table 222 stores user contract information when each of the users A and B makes a contract with an Internet service provider that manages the Internet service provider device 203 (FIG. 7). Specifically, it is user ID of each user A and B, a password, a date of birth, sex, an address, and a job type. By comparing the date of birth with the current date, the age of the users A and B can be calculated.

  FIG. 10 shows the contents of the IPv6 extended header table in the first embodiment. The IPv6 extended header creation unit 223 shown in FIG. 7 creates the IPv6 extended header table 224 using the user access table 221 shown in FIG. 8 and the user contract information table 222 shown in FIG. That is, “user ID” and “IPv6 address” are extracted from the user access table 221 for each user, and “gender” and “job type” of the user whose “user ID” matches are extracted from the user contract information table 222 as “IPv6 extended header information”. ”And the age of the user found from“ birth date ”is added to“ IPv6 extended header information ”.

  FIG. 11 shows a state of access processing to the content service provider apparatus when the user terminal acquires content information. This will be described with reference to FIG.

  For example, it is assumed that the user A acquires desired content information from the content service provider device 205 using the first user terminal 211. The first user terminal 211 creates an IPv6 packet 242 for acquiring content information incorporating the user A data 241 and sends it to a communication control unit (not shown) of the first user terminal 211 to send it to the destination content service provider. A request for transmission to the device 205 is made (step S301). When the second user terminal 212 makes a similar request, an IPv6 packet 244 for acquiring content information in which the user B data 243 is incorporated is created and the transmission request is made.

  The communication control unit described above of the first user terminal 211 determines whether or not the first user terminal 211 is connected to the Internet via the Internet service provider device 203 (step S302). If it is connected to the Internet (Y), an IPv6 packet 242 for acquiring the content information is transmitted (step S303), and the access processing to the content service provider device 205 is ended (END). . That is, after this, it waits for content information to be sent from the content service provider device 205.

  On the other hand, if the first user terminal 211 is not connected to the Internet 204 in Step S302 (N), the login information is entered on the login dedicated tool 213 to log in to the Internet service provider device 203 (Step S304). ). When the second user terminal 212 is not connected to the Internet 204 (N), login information is entered on the login dedicated tool 214 to log in to the Internet service provider apparatus 203. When the login is completed, the first user terminal 211 connects to the Internet 204 via the Internet service provider device 203 (step S305). Therefore, the process proceeds to step S303, where an IPv6 packet 242 for acquiring content information is transmitted, and access for acquiring content information is ended (END).

  FIG. 12 shows a state of content information request processing to the content service provider device of the Internet service provider device based on the access of the user terminal. This will be described with reference to FIGS.

  A communication control unit (not shown) of the Internet service provider apparatus 203 uses IPv6 packets such as the IPv6 packets 242 and 244 from the first user terminal 211 described with reference to FIG. 11 (hereinafter, the case of IPv6 packets 242 will be described as an example). Is waiting to be received (step S321). When the IPv6 packet 242 is received (Y), it is checked whether or not the “IPv6 extended header information” of the user A is already stored in the IPv6 extended header table 224 (step S322). If not already stored in the IPv6 extension header table 224 (N), the IPv6 extension header creation unit 223 creates “IPv6 extension header information” (step S323). Then, the created “IPv6 extension header information” is stored in the IPv6 extension header table 224 (step S324). Thereafter, the IPv6 extension header adding unit 225 receives the IPv6 packet 242 from the communication control unit (step S325). If it is determined in step S322 that “IPv6 extended header information” of user A has already been stored in the IPv6 extended header table 224 (Y), the process immediately proceeds to step S325.

  When the process of step S325 is completed, the IPv6 extension header adding unit 225 then refers to the IPv6 extension header table 224 (step S326). Then, the IPv6 extension header adding unit 225 adds “IPv6 extension header information” to the IPv6 packet 242 based on the “user ID” of the user A (step S327). Thereafter, the communication control unit transmits an IPv6 packet 252 (FIG. 7) obtained by adding the IPv6 extension header information 251 to the user A data 241 to the content service provider apparatus 205 (step S328). When the user B requests content information, the communication control unit described above transmits an IPv6 packet 254 (FIG. 7) in which the IPv6 extension header information 253 is added to the user B data 243 to the content service provider device 205. This completes the content information request processing for the content service provider device 205 of the Internet service provider device 203 (end). However, it is assumed that the IPv6 extension header information 251 and 253 is standardized in the Internet 204 by the above processing.

  FIG. 13 shows a state of processing in response to a content information acquisition request from the Internet service provider device by the content service provider device. This will be described with reference to FIG.

  When the communication control unit (not shown) of the content service provider apparatus 205 receives the IPv6 packet 252 related to the user A in step S328 in FIG. 12 (step S341: Y), the IPv6 extension header analysis unit 231 stores the IPv6 extension header information 251. Analysis is performed (step S342). When the IPv6 packet 254 related to the user B is received (step S341: Y), the IPv6 extension header analysis unit 231 analyzes the IPv6 extension header information 253.

  The IPv6 extension header analysis unit 231 acquires the user information of the user A from the analysis result of the IPv6 extension header information 251 (Step S343). Then, the user A's user information is selected from the content information requested by the user A stored in the data storage unit 232 (step S344). From the “IPv6 extended header information” in the IPv6 extended header table 224 of FIG. 10, the user information of the user A is found to be a 40-year-old male and a company employee. Therefore, content information suitable for such user A is selected. When the IPv6 extended header information 253 is analyzed, it is understood from the “IPv6 extended header information” that the user B is a 16-year-old female student. Therefore, content information suitable for such user B is selected.

  Therefore, the communication control unit of the content service provider device 205 transmits the selected content information to the user (step S345), and ends the processing (END). As shown in FIG. 7, when the user A is the destination, the IPv6 packet 262 incorporating the content information 261 for the user A is transmitted to the first user terminal 211 via the content service provider device 205. . When the user B is the destination, the IPv6 packet 264 incorporating the content information 263 for the user B is transmitted to the second user terminal 212 via the content service provider device 205.

  In this way, the user A and the user B can acquire the content information 261 and 263 that are suitable for each from the content service provider device 205 using the first user terminals 211 and 212.

  FIG. 14 specifically shows information storage processing for the IPv6 extension header table shown in FIG. This will be described with reference to FIGS.

  When a request for storing table information for the IPv6 extended header table 224 is generated in the Internet service provider apparatus 203 (step S361: Y), the Internet service provider that manages the Internet service provider apparatus 203 and the Internet are requested by the requested user. A check is made as to whether a contract has been made regarding the use of 204 (step S362). This user will be described as user B. When the user B has not made a contract yet (N), the Internet service provider apparatus 203 makes a “user contract and sends the user contract information to the Internet service provider apparatus 203 to the second user terminal 212. "Notify" is requested (step S363). For such a request, for example, a request message is registered in advance in the Internet service provider device 203, and this message is transmitted to the second user terminal 212 of the user B and displayed on the display screen. You can do it.

  In response to this request, the second user terminal 212 of the user B is used to process the contract by an online method and the contract information is sent (step S364: Y), the Internet service provider apparatus 203 receives the user contract. The contract information is recorded in the information table 222 (step S365). Next, the internet service provider apparatus 203 confirms that the user B is logged in to the internet service provider apparatus 203 using a login dedicated tool (step S366). If it is determined in step S362 that the user B has already contracted with the Internet service provider that manages the Internet service provider device 203 (Y), the process immediately proceeds to step S366.

  When confirming the login as the next step S367, the Internet service provider apparatus 203 records the user ID and the IPv6 address in the user access table 221 (step S367). Then, the IPv6 extension header creation unit 223 collates the user contract information of the same user ID in the user contract information table 222 using the user ID of the user access table 221 (step S368). In the case of user B, the user ID to be collated is “7899012”. The IPv6 extension header creation unit 223 creates the IPv6 extension header information by using the user contract information such as the date of birth “1992/8/7” and the sex “female” in the user contract information table 222 corresponding to this user ID. (Step S369). Then, the user ID “789012”, the IPv6 address “FDE2: ABCD :: 2”, and the IPv6 extended header information created in step S369 are stored in the IPv6 extended header table 224 (step S370). In this way, the storage process of information related to the user B in the IPv6 extended header table 224 ends (end).

  Finally, FIG. 15 shows an example of an IPv6 packet incorporating IPv6 extension header information used in this embodiment. The IPv6 packets 252 and 254 incorporating the IPv6 extension header information 251 and 253 shown in FIG. 7 are an IPv6 header 271, an IPv6 extension header 272 following the IPv6 header 271, and a UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) header. 273, followed by application data 274. The IPv6 extension header 272 includes a “next header” column 281 indicating that an extension header exists following the IPv6 header 271 and an “extension header length” column 282 indicating the extension header length, followed by “age”. , A user information description column 283 representing “sex” and “job type” in order is incorporated. Therefore, for example, by assigning a decimal number of 3 digits to “age”, it is possible to specify the age of a user over 100 years of age from “000” whose age is unknown (unknown), and 1 digit in decimal for “gender” For example, a one-digit number in decimal is assigned to “occupation”.

  As described above, according to the first embodiment, the following effects can be obtained.

  First, in the first embodiment, there is a first effect that the content service provider apparatus 205 can obtain highly reliable user information. This is because the user information provided to the content service provider device 205 is stored in the IPv6 extension header added to the IPv6 packet in the Internet service provider device 203 in the first embodiment. That is, in the first embodiment, user information provided to the content service provider device 205 by each user is directly defined. For this reason, the operator of the user terminal cannot intentionally misrepresent user information. As a result, the user information provided to the content service provider device 205 is highly accurate and reliable information.

  Next, in the first embodiment, there is a second effect that the user can acquire content information suitable for the user. In the first embodiment, the content service provider device 205 selects the content suitable for the user from the contents stored in the data storage unit 232 based on the highly reliable user information and provides it to the user. is there.

  In the first embodiment, there is a third effect that profits from the content service provider device 205 can be expected. If the content service provider device 205 prepares content information useful for the user, the number of users increases. In addition, content information inappropriate for the user can be removed in advance by the content service provider device 205 and provided to the user, so that the user's selection work is not required, and in this respect, the user's satisfaction is increased and the content is increased. Access to the service provider device 205 increases. As a result, it is possible to expect an increase in revenue such as advertising revenue of content.

  Furthermore, in the first embodiment, there is a fourth effect that the user can save the trouble of making a contract with the content service provider apparatus 205. This is because the content service provider device 205 extracts the IPv6 extension header information from the user information presented when the user makes a contract with the Internet service provider device 203 in the first embodiment. This is because it is not necessary to make a contract with the service provider device 205.

  <Possibility of deformation of the first embodiment>

  In the first embodiment described above, the gender, job type, and age of the user are used as the IPv6 extension header information, but the present invention is not limited to these. For example, as IPv6 extension header information, local information such as address and school of origin, in-house information such as company, department, and position where the user works, campus information such as undergraduate department of a university or laboratory, or laboratory, or Some or all of your health information can be used. Thereby, it is possible to perform access control of the network layer (Layer 3) appropriately using user information in each network or content service provider.

  Note that the bit length of the user information description column 283 of the IPv6 extension header 272 shown in FIG. 15 may change by changing the configuration of the IPv6 extension header information. In this case, the length may be changed as appropriate in the “extension header length” column 282. In the first embodiment, only one content service provider device 205 is shown. However, there may be cases where there are several types of user information handled by each of the content service provider devices 205 in the whole world. . In such a case, identification information indicating which type corresponds to the user information may be described in a predetermined fixed length at the top of the user information description field 283. For example, when the user's gender, job type, and age are expressed in decimal numbers in this order as a total of 5 digits as in this embodiment, the type is A, and the address, area information, in-house information, campus information, and health information are specified. When represented by the number of bits, the type B is used.
