When information disclosure is requested from communication terminals 100-2/100-3 and the communication terminals 100-2/100-3 are included in the disclosure range, an information disclosure part 202 discloses the information to the communication terminal 100-2/100-3.

Description

  The present invention relates to a communication system, a communication terminal, a server, a communication method, and a program for performing communication.

  In recent years, with the rapid spread of the Internet, information provision and information exchange via the Internet have been actively performed. In order to provide information and exchange information via the Internet, a social networking service (SNS) such as Facebook (registered trademark) has been established. SNS has many users who have registered private information, and can browse the hobbies and preferences of the users.

  In such SNS, a technique for determining the disclosure range of the information based on the evaluation value given to the creator who created the registered information (content) is considered (for example, see Patent Document 1). .)

JP2011-48445A

  However, in the SNS using the technique described in Patent Document 1, registered information may be disclosed to a third party who does not want to be known.

Further, the user ID “C”, the friend “B”, and the friend “A” of the friend are associated with each other and stored in the user management unit 204. This indicates that the friend of the user whose user ID is “C” is a user whose user ID is “B”. The user whose user ID is “A” is a friend of the user's friend whose user ID is “C”. Further, a user ID “D”, a friend “A”, a friend friend “B”, and a close friend “A” are associated with each other and stored in the user management unit 204. This indicates that the friend of the user whose user ID is “D” is the user whose user ID is “A”. The user whose user ID is “A” is a close friend of the user whose user ID is “D”. The user whose user ID is “B” is a friend of the user's friend whose user ID is “D”.

  Disclosure range determination unit 201 determines a range (disclosure range) for disclosing post information based on the content of post information received by reception unit 203. Also, the disclosure range determination unit 201 registers the determined disclosure range, the posted information, and the user ID of the user who has transmitted (posted) the posted information in the registration unit 205 in association with each other.

  Here, a method for determining the disclosure range will be described.

  The disclosure range determination unit 201 determines the disclosure range based on the number of predetermined words included in the posted information received by the reception unit 203. For example, when a proper noun is included in the posted information, the disclosure range determining unit 201 determines the confidentiality of the posted information based on the number of proper nouns, and limits the disclosed range. At this time, the disclosure range determination unit 201 determines that the confidentiality of the posted information is high when the number of proper nouns is greater than a preset threshold, and discloses the disclosure range only to users who are close to the user. To decide. Moreover, it may be based not only on the number of proper names but also on the frequency of use.

  Also, the disclosure range determination unit 201 sets a numerical value for each word in advance, sums the numerical values of each word included in the posting information, and determines the confidentiality of the posting information based on the total numerical value. The disclosure range may be limited. At this time, the disclosure range determination unit 201 determines that the confidentiality of the posted information is high when the total number is greater than a preset threshold value, and discloses the disclosure range only to users who are close to the user. decide.

  Also, the disclosure range determination unit 201 registers the range information indicating the determined range, the posting information, and the user ID in the registration unit 205 in association with each other.

  The registration unit 205 stores the range information indicating the range determined by the disclosure range determination unit 201 and the post information and user ID received by the reception unit 203 in association with each other.

  FIG. 5 is a diagram illustrating an example of association stored in the registration unit 205 illustrated in FIG. 3.

  As illustrated in FIG. 5, the registration unit 205 illustrated in FIG. 3 stores a user ID, a posting content that is posting information, and a disclosure range that is range information in association with each other. For example, as shown in FIG. 5, a user ID “A” is associated with a posting content “Drinking with Yamada and Tanaka of NEC at an Izakaya in Musashikosugi” and a disclosure range “D”. 205 is stored. This is a range in which “Drinking with Yamada and Tanaka of NEC at Musashi Kosugi Izakaya” posted by a user with a user ID “A” is used for a user ID “D”. It shows that it is a person. In addition, the user ID “B”, the posted content “Drinking with friends at a tavern”, and the disclosure ranges “A”, “C”, and “D” are associated with each other and stored in the registration unit 205. . The range of disclosing “drinking with friends at a tavern” posted by a user whose user ID is “B” is “C”, a user whose user ID is “A”. A user who is a user and a user who is a user who is “D” are shown.

  Thus, for example, if the posted content posted by a user whose user ID is “B” is “drinking with a friend at an izakaya”, since the posted content does not include a proper noun, it is disclosed. The range determination unit 201 determines that the confidentiality of the posted content is low, and the disclosure range includes the friend and the friend of the friend associated with the user ID “B” in the relevance information illustrated in FIG. 4. And In addition, if the posted content posted by the user with the user ID “A” is “Drinking with Yamada and Tanaka of NEC at a Musashi Kosugi izakaya”, the posted content includes “Musashi Kosugi”, “ Since the four proper nouns “NEC”, “Yamada”, and “Tanaka” are included, the disclosure range determining unit 201 determines that the posted content includes a lot of information related to privacy and has high confidentiality. Only the close friend associated with the user ID “A” is included in the disclosure range. At this time, as described above, the disclosure range determination unit 201 compares the number of proper nouns included in the posted content with a preset threshold value, and determines confidentiality based on the result. May be. For example, when two threshold values (for example, “2” and “4”) are set and the number of proper nouns is less than “2”, the disclosure range determination unit 201 determines the rank indicating the degree of confidentiality. When the value is “0”, the disclosure range is determined as “friend”, “friend of friend” and “close friend” shown in FIG. 4, and the number of proper nouns is “2” or more and less than “4” The disclosure range determination unit 201 sets the rank value indicating the degree of confidentiality to “1”, determines the disclosure range as “friend” and “close friend” illustrated in FIG. 4, and the number of proper nouns is “4”. In the case described above, the disclosure range determination unit 201 may set the rank value indicating the degree of confidentiality to “2” and determine the disclosure range as “close friend” illustrated in FIG.

  Further, in the above-described example, the user management unit 204 stores relevance information that is related to the closeness between users, and the disclosure range determination unit 201 determines whether the relevance information is posted based on the relevance and the posted content. Although the disclosure range has been determined, other relevance information may be used. For example, relevance information indicating the relevance with a person involved in work or a family may be used. When using relevance information that indicates the relevance of the person involved in the work, the intimacy with the person involved in the work (whether it is a person in the same department, a person in the next department, an external customer, etc. ) And work-related words are set in advance, and the disclosure range determination unit 201 determines the disclosure range in accordance with the number of set words included in the posted content (if there are many words, the relationship is more intimate) It may be determined to be disclosed only to a person who wants to disclose.

  When the disclosure of post information is requested from the communication terminals 100-1 to 100-3, the information disclosure unit 202 communicates with the communication terminal 100 based on the correspondence between the posting contents registered in the registration unit 205 and the disclosure range. It is determined whether −1 to 100-3 are included in the disclosure range. As a result, when the communication terminals 100-1 to 100-3 are included in the disclosure range, the information disclosure unit 202 reads the requested posting content from the registration unit 205 and discloses it to the communication terminals 100-1 to 100-3. (Send.

  Hereinafter, a communication method in the communication system shown in FIG. 1 will be described. Here, the case where the relevance information shown in FIG. 4 is stored in the user management unit 204 will be described as an example.

  FIG. 6 is a sequence diagram for explaining processing for registering posted information in the communication method in the communication system shown in FIG.

  First, authentication processing of the communication terminal 100-1 is performed between the communication terminal 100-1 and the server 200 (step S1). This authentication process may be the same as a general one, and may use a user ID and a password. In addition, user information stored in the user management unit 204 is used for this authentication.

  Thereafter, when the user of the communication terminal 100-1 operates the input unit 101 and the input unit 101 receives input of post information (step S2), the transmission unit 102 transmits the post information to the server 200 ( Step S3).

  When the receiving unit 203 of the server 200 receives the posted information transmitted by the transmitting unit 102 (step S4), the disclosure range determining unit 201 determines the confidentiality of the posted information based on the posted information (step S5). . Specifically, as described above, the disclosure range determination unit 201 determines the confidentiality based on the number of predetermined words included in the posted information and the sum of numerical values set in advance for each word. To give a rank value.

  The disclosure range determination unit 201 determines whether there is a group with a rank value or higher (step S6). For example, when the rank value is “0”, “friends”, “friends of friends” and “close friends” shown in FIG. When the rank value is “1”, “friends” and “close friends” shown in FIG. Further, when the rank value is “2” or more, the “close friend” shown in FIG. 4 becomes the corresponding group.

  When there is a group equal to or higher than the rank value, the disclosure range determination unit 201 determines the disclosure range based on the rank value (step S7). That is, when the rank value of the posted information posted from the user whose user ID is “A” is “0”, the disclosure range determining unit 201 uses the user whose user ID is “B”, the usage A user whose user ID is “C” and a user whose user ID is “D” are determined as the disclosure range. In addition, when the rank value of the posted information posted from the user whose user ID is “A” is “1”, the disclosure range determination unit 201 and the user whose user ID is “B” and the usage The user whose user ID is “D” is determined as the disclosure range. Also, the disclosure range determination unit 201 determines the user whose user ID is “D” when the rank value of the posted information posted from the user whose user ID is “A” is “2” or more. To be determined as the scope of disclosure.

  Subsequently, the disclosure range determination unit 201 registers post information in the registration unit 205 (step S8). At this time, the disclosure range determination unit 201 registers the user ID of the user who posted the posting information and the disclosure range in the registration unit 205 in association with the posting information.

  On the other hand, when there is no group equal to or higher than the rank value in step S6, the disclosure range determining unit 201 associates the user ID of the user who posted the posted information with the posted information in step S8. And registering in the registration unit 205. In this case, the server 200 notifies the communication terminal 100-1 that there is no group equal to or higher than the rank value, and urges the user of the communication terminal 100-1 to change the posted content or the relevance information. There may be. If the posting content is changed or the relevance information is changed based on this notification, even if the server 200 performs the processing from step S5 based on the post content and the relevance information after the change. good.

  FIG. 7 is a sequence diagram for explaining processing for disclosing posted information in the communication method in the communication system shown in FIG. Here, the case where communication terminal 100-2 requests the disclosure of post information will be described as an example. The case where the association shown in FIG. 5 is stored in the registration unit 205 will be described as an example.

  First, authentication processing of the communication terminal 100-2 is performed between the communication terminal 100-2 and the server 200 (step S11). This authentication process may be the same as a general one, and may use a user ID and a password. In addition, user information stored in the user management unit 204 is used for this authentication.

  Thereafter, when the user of the communication terminal 100-2 operates the input unit 101 and the input unit 101 receives an input of a posting request for posting information (step S12), the transmitting unit 102 indicates a disclosure request signal indicating the disclosure request. Is transmitted to the server 200 (step S13). At this time, the transmission unit 102 transmits the user ID to the server 200 together with the disclosure request signal.

  When the reception unit 203 of the server 200 receives the disclosure request signal transmitted by the transmission unit 102 (step S14), the information disclosure unit 202 moves the user of the communication terminal 100-2 within the disclosure range registered in the registration unit 205. It is determined whether or not there is a user ID included (step S15).

  In the case where there is one that includes the user ID of the user of the communication terminal 100-2, the information disclosure unit 202 displays post information registered in association with the user ID included in the disclosure range. The data is read from the registration unit 205 and disclosed to the communication terminal 100-2 (step S16). Then, the output unit 104 of the communication terminal 100-2 outputs (displays) the posted information. For example, when the user ID of the communication terminal 100-2 is “C”, the information disclosure unit 202 includes post information (post content) in which “C” is included in the disclosure range of association illustrated in FIG. “Drinking with a friend at a tavern” is read and disclosed to the communication terminal 100-2. And the output part 104 of the communication terminal 100-2 outputs (displays) "I drink with a friend at a pub."

  On the other hand, when there is nothing including the user ID of the user of the communication terminal 100-2, the information disclosure unit 202 performs a process that is not disclosed (step S17). Specifically, information indicating that there is no posted information to be disclosed is transmitted to the communication terminal 100-2, and the output unit 104 of the communication terminal 100-2 outputs (displays) information indicating that there is no posted information to be disclosed. ) For example, when the user ID of the communication terminal 100-2 is “B”, the information disclosure unit 202 includes post information (post content) in which “B” is included in the disclosure range of the association illustrated in FIG. Since there is no such information, the fact is transmitted to the communication terminal 100-2.

  Further, the communication terminal 100-1 may determine the disclosure range.

  FIG. 8 is a diagram showing another example of the internal configuration of communication terminal 100-1 shown in FIG.

  As illustrated in FIG. 8, the communication terminal 100-1 illustrated in FIG. 1 includes a transmission unit 102 and a disclosure range determination unit 105.

  FIG. 9 is a diagram showing an example of a detailed internal configuration of communication terminal 100-1 shown in FIG.

  As illustrated in FIG. 9, the communication terminal 100-1 illustrated in FIG. 8 includes an input unit 101, a transmission unit 102, a reception unit 103, an output unit 104, and a disclosure range determination unit 105. . FIG. 9 shows an example of main components related to the present embodiment among the components provided in communication terminal 100-1 shown in FIG.

  The input unit 101, the receiving unit 103, and the output unit 104 are the same as those shown in FIG.

  When the input unit 101 receives input of posted information, the disclosed range determining unit 105 determines a disclosed range for disclosing the posted information based on the content of the received posted information. The disclosure range determination method is the same as the method in the disclosure range determination unit 201 illustrated in FIG.

  The transmission unit 102 transmits the posting information received by the input unit 101 and the disclosure range information indicating the disclosure range determined by the disclosure range determination unit 105 to the server 200.

  In this way, the communication terminal 100-1 determines the disclosure range, and transmits the disclosure range information indicating the determined disclosure range to the server 200, so that the communication terminal does not determine the disclosure range in the server 200. The posting information and the disclosure range information transmitted from 100-1 can be registered in the registration unit 205. Needless to say, the communication terminals 100-2 and 100-3 may have this function.

  As described above, since the disclosure range is determined based on the content of the posted information, disclosure according to confidentiality is prevented, such as preventing the posted information from being disclosed to users who do not want to be disclosed. It can be carried out. Further, it is possible to save the user from setting the disclosure range.

  Note that the communication terminals 100-1 to 100-3 described above are electronic devices such as mobile phones, mobile terminals, tablet-type and notebook-type PCs (Personal Computers), smartphones, PDAs (Personal Digital Assistants), and game machines. .

  The processing performed by each component provided in each of the communication terminals 100-1 to 100-3 and the server 200 described above may be performed by a logic circuit that is produced according to the purpose. In addition, a computer program (hereinafter referred to as a program) in which processing contents are described as a procedure is recorded on a recording medium readable by each of the communication terminals 100-1 to 100-3 and the server 200, and recorded on the recording medium. The program may be read and executed by each of the communication terminals 100-1 to 100-3 and the server 200. The recording media readable by each of the communication terminals 100-1 to 100-3 and the server 200 include communication media such as a floppy (registered trademark) disk, a magneto-optical disk, a DVD, a CD, and the like, as well as the communication terminal 100. -1 to 100-3, a memory such as a ROM and a RAM, an HDD, etc. built in each of the servers 200. The program recorded on the recording medium is read by a CPU (not shown) provided in each of the communication terminals 100-1 to 100-3 and the server 200, and the same processing as described above is performed under the control of the CPU. Done. Here, the CPU operates as a computer that executes a program read from a recording medium on which the program is recorded.
