Description

  The present invention relates to a common attribute information search apparatus, a common attribute information search method, and a common attribute that are used by at least two users who have registered attribute information representing their characteristics at a network service site established on a communication network. More specifically, the present invention relates to a technique for searching for common attribute information between users.

  2. Description of the Related Art In recent years, services that have established new friendships using community-type websites established on communication networks such as the Internet have become widespread. Such a service is called a social network service (hereinafter referred to as “SNS service”), and has a date of birth, place of birth, school (education), work (profession), e-mail address, blood type in advance. By performing attribute information that expresses its own characteristics such as hobbies, favorite sports, favorite foods, it can be used to build new friendships. Such an SNS service can be used if there are no invitations from existing participants who have become members after registering attribute information in advance, in addition to those that can be freely joined by an unspecified number of people. Some things are not possible.

In addition, in the conventional SNS service, when participating in the SNS service or building a friendship, a part or all of the attribute information registered at the time of participating in the SNS service is disclosed to other participants by public setting. It is supposed to be. This disclosure of attribute information makes it easier to build new friendships by expanding the scope of the attribute information.
Therefore, if more detailed attribute information is registered and publicly set, it is easy to establish new friendships or deeper friendships based on the attribute information common to each other.
In view of this, several means for searching for a person who meets the user's (participant) request have been proposed (see, for example, Patent Documents 1 to 3).

However, any of the means described in Patent Documents 1 to 3 performs a search for all the participants registered in the service based on the attribute information set and registered as open to other participants. The search for attribute information common to a specific participant is not performed in more detail.
In other words, in the attribute information, information that may generally be disclosed to other participants (hereinafter referred to as “publicly available information”) and even participants who have established friendships are disclosed. There is information with resistance (hereinafter referred to as “public information”).
However, in addition to those that cannot be used without an invitation from an existing participant who has become a member of the SNS service, anyone can freely use an unspecified number of members without an invitation from a member, etc. There is something you can join. Therefore, even if it is publicly available information, if it is unnecessarily released, it may be misused for fictitious claims or impersonation.
In addition, since there is a high possibility that information that cannot be disclosed is registered from the beginning, it has been very difficult to establish a new friendship with a friend in the same situation based on the information that cannot be disclosed.

Therefore, it is possible to search for detailed attribute information with participants in a safe and secure manner without illicitly using publicly available information, No means have been proposed for searching that can build friendships.

And a message for confirming whether or not the second user and the attribute information may be compared and searched based on the contact information. It has a function of performing a search process on condition that it receives an answer from the user terminal 20 that it agrees to perform a comparative search of attribute information with the second user.

At this time, the common attribute item search unit 13 includes, for example, a search execution confirmation unit 13a, a common attribute item specifying unit 13b, a common attribute item number calculating unit 13c, a common attribute item number order rearranging unit 13d, and a common attribute. The item number ratio calculation unit 13e and the attribute information extraction unit 13f may be included.
That is, after the search execution confirmation unit 13a specifies the first user ID in the search request second processing unit 12, the user information storage unit DB1 is referred to and contact information is obtained based on the first user ID. A message is sent to the first user terminal 20 confirming whether the second user and the attribute information may be compared based on the contact information, and the first user The search process is executed on the condition that the terminal 20 receives a reply that the second user and the attribute information are agreed to be compared.

Next, the common attribute item specifying unit 13b refers to the user information storage unit DB1 based on the specified first user ID and second user ID, and determines the attribute information of the first user and the second user. Compared for each item, common attribute items having the same attribute information are specified.
When there are a plurality of second users, the common attribute item specifying unit 13b compares the attribute information of the first user and each second user for each item, and the attribute information of the second user for each item. The common attribute item having the same attribute information is identified.
In addition, when there are a plurality of second users, the common attribute item specifying unit 13b compares the attribute information of the first user and all the second users for each item, and the attribute information of at least two or more users Identify common attribute items that are the same. The identified common attribute item is transmitted to the search result transmission unit 14.

  In addition, the common attribute item number calculation unit 13c calculates the number of specified common attribute items for each user. The calculated number of common attribute items is transmitted to the search result transmission unit 14. Here, the number of common attribute items refers to the number of attribute items that are determined to be the same, for example, the attribute information in the attribute items such as the school of origin, blood type, and sports are the same. If it is determined that there is, the number of common attribute items is “3”.

  Further, the common attribute item number order rearranging unit 13d rearranges the calculated number of common attribute items in order of size. The rearranged common attribute items are transmitted to the search result transmission unit 14.

  Further, the common attribute item number ratio calculation unit 13e calculates the ratio of the number of common attribute items to the number of all compared items. The calculated ratio of the number of common attribute items is transmitted to the search result transmission unit 14. Here, the ratio of the number of common attribute items refers to, for example, a number that represents 100 as the highest. Specifically, there are 10 compared items, and the common attribute items have the same attribute information. The ratio when the number is 4 is “40”. The number of all items compared may be the number of items for which responses are set in advance or the number of common items for which responses have been made.

  Further, the attribute information extraction unit 13f extracts attribute information corresponding to the specified common attribute item for each user. The extracted attribute information is transmitted to the search result transmission unit 14.

The search result transmission unit 14 performs a process of notifying the first user terminal 20 and the second user terminal 30 of the search result.
The search result can be attribute information extracted for each user by the common attribute item search unit 13 or the number of common attribute items calculated by the common attribute item search unit 13.
As a result of the search, the ratio of the calculated number of common attribute items may be used instead of the number of common attribute items.

The search end unit 15 performs processing for instructing the common attribute item search unit 13 to prohibit the use of the search request acceptance information (search PW).
At this time, the search end unit 15 may be configured of, for example, one or more of a search end first instruction unit 15a, a search end second instruction unit 15b, and a search end third instruction unit 15c. .

  In response to the issuance of the search PW in the search request first processing unit 11, the search end first instruction unit 15a temporarily stores the search PW issue time in association with the search PW, and issues the stored search PW. When a predetermined time or a time set by the first user has elapsed from the time, a process for storing information on prohibition of use of the search PW in the search request reception information storage unit 2 is performed.

  The search end second instruction unit 15b confirms the communication connection status with the first user terminal 20 at regular intervals in response to reception of the search PW issuance request in the search request first processing unit 11, and the first user terminal When the connection with 20 is disconnected, a process of storing information on prohibition of use of the search PW in the search request reception information storage unit 2 is performed based on the identification information of the first user.

  When the search end third instruction unit 15c receives a search end request together with the first user ID from the first user terminal 20, the search end third instruction unit 15c accepts the search request based on the identification information of the first user included in the search end request. A process of storing information on prohibition of use of information in the second storage means is performed.

Next, an example of the method executed by the server 10 shown in FIG. 2 will be described with reference to the drawings.
In this method, the first user and the second user search for the attribute information on a one-to-one basis (first embodiment), and the first user and the participant who are the organizers And a plurality of second users can be broadly divided into group search (second embodiment) for searching for attribute information.

<First Embodiment>
First, as a first embodiment, an outline of attribute information search when a first user and a second user are paired will be described with reference to FIG.
As shown in FIG. 1, a first user using the first user terminal 20 accesses a common attribute search site and requests the server 10 to issue a search PW as search request acceptance information (1 .reference). This search request acceptance information can be, for example, one-time PW.
The server 10 receives the search PW issue request, issues the search PW, and transmits it to the first user terminal 20 (see 2.). At this time, the search PW is stored together with the first user information of the transmission destination.

The first user terminal 20 receives the search PW, and the first user acquires the search PW (see 3.).
Next, the first user notifies the second user of the search PW by oral or electronic mail (see 4.).
The second user who uses the second user terminal 30 accesses the common attribute search site and inputs the search PW acquired from the first user (see 5.).

The server 10 receives the search PW and specifies the first user information based on the search PW (see 6.).
Subsequently, the server 10 transmits a confirmation message to the first user terminal 20 as to whether or not the common attribute search with the second user may be performed (see 7.).
The first user terminal 20 transmits an answer that agrees to perform a common attribute search with the second user to the server 10 (see 8.).
The server 10 searches for attribute information common to the first user and the second user based on the agreement of the first user (see 9.).

Then, the server 10 notifies the first user terminal 20 and the second user terminal 30 of the common attribute information obtained by the search (see 10.).
The first user terminal 20 acquires the common attribute information with the second user from the server 10, and the first user browses (see 11A.), And the second user terminal 30 Is acquired from the server 10, and the second user browses (see 11B.).

  This makes it possible to effectively share new friends with friends in the same situation based on the information you do not want to publish, by publishing the information you do not want to publish unnecessarily only when they match each other. Can be built.

A detailed example of the method executed as the first embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram illustrating a basic processing flow of the common attribute information search method according to the first embodiment.
In the present embodiment, the first user terminal 20 connected via the communication network NW downloads the homepage of the SNS service site and requests the search PW obtained by requesting the issuance of the search PW from the homepage. 2 users are notified. Subsequently, the first user and the second user are specified based on the second user ID and the search PW obtained from the second user terminal 30, and the first user and the second user are set as search targets. A case where search is performed for attribute information common to each other will be described.

  First, the server 10 stores the user ID, attribute information including at least one item registered in advance by the user, and contact information for the user terminal in the user information DB 1 in association with each other (( A)).

Next, the first user activates the first user terminal 20, connects to the server 10 via the communication network NW, accesses the SNS service site built in the server 10, and downloads the home page.
The first user visits the SNS service site, inputs a user ID assigned in advance and a password set in advance, and logs in. Note that the first user ID is temporarily stored during login.
This SNS service site can be expressed, for example, in the form shown in FIG. FIG. 14 is a diagram illustrating an example of the login screen of the SNS site displayed on the display of the first user terminal 20 connected to the server 10. The SNS site login screen 100 has a user ID input field 101 for confirming that the member can use this system, along with a guidance such as “Enter your ID and password and press the send button.” A member login field including a password input field 102 is displayed. The SNS site login screen 100 also displays a “Send” button 109 for executing login with the user ID and password entered in the member login field.

Therefore, if the person who searches the attribute information on the SNS service site is a member, he / she inputs the user ID in the user ID input field 101 and the password in the password input field 102, and then clicks the “Send” button 109. Select and login.
When the “Send” button 109 is selected on the SNS site login screen 100, it is recognized that the member is registered as a result of the authentication, and the menu selection screen is continuously displayed on the display of the first user terminal 20 by logging in. .

  This menu selection screen can be expressed, for example, as shown in FIG. FIG. 15 is a diagram illustrating an example of a menu selection screen displayed on the display of the first user terminal 20 connected to the server 10. On this menu selection screen 110, an “issue search password” button 111 for requesting issuance of a search PW, an “execute attribute information search” button 112 for requesting search for attribute information, and an end request for attribute information search are requested. An “end attribute information search” button 113,... And an “end” button 119 for ending the work on the SNS service site are displayed.

Therefore, the user who requests the issuance of the search PW selects the “issue search password” button 111.
Thereby, the first user terminal 20 transmits a search PW issuance request to the server 10 (see (10)).

The server 10 receives the search PW issue request transmitted from the first user terminal 20 (see (20)).
Next, the server 10 issues a search PW to the first user (see (30)).
Subsequently, the server 10 stores the issued search PW in the search request reception information storage unit 2 in association with the first user ID (see (40)).
Further, the server 10 transmits the issued search PW to the first user terminal 20 (see (50)).

The first user terminal 20 receives the search PW transmitted from the server 10 (see (60)).
That is, when the “issue search password” button 111 is selected on the menu selection screen 110 displayed on the display of the first user terminal 20, the search PW notification screen is continuously displayed on the display of the first user terminal 20.
This search PW notification screen can be expressed, for example, in the form shown in FIG. FIG. 16 is a diagram illustrating an example of a search PW notification screen displayed on the display of the first user terminal 20 connected to the server 10. The search PW notification screen 120 displays a search PW display field 121 for notifying the search PW issued to the first user. In addition, the search PW notification screen 120 displays a “Yes” button 128 and a “No” button 129 for selecting whether or not the effective time of the issued search PW is set.

  The valid time of the search PW can be arbitrarily set by a predetermined time set in advance or by the first user who has issued a search PW issue request. Accordingly, when the valid time is set in advance, the predetermined time is set by selecting the “Yes” button 128. On the other hand, when the valid time is arbitrarily set, a screen (not shown) for further setting the valid time is displayed by selecting the “Yes” button 128. If the “No” button 129 is selected, a standby screen (not shown) is displayed until a notification of confirmation of attribute information search to be described later is received, or the work on the SNS service site is once ended.

Next, the first user notifies the second user who wishes to search for common attribute information for confirming the connection between the users by oral or electronic mail or the like (see 70A).
The second user acquires the search PW from the first user (see 70B).
When the second user receives a search for common attribute information desired by the first user, the second user activates the second user terminal 30 and connects to the server 10 via the communication network NW. Go to the SNS service site built in and download the homepage.
The second user visits the SNS service site, inputs a user ID given in advance and a password set in advance, and logs in. This SNS service site can be expressed in the form shown in FIG. Note that the second user ID is temporarily stored during login.

When logging in, the menu selection screen is continuously displayed on the display of the second user terminal 30. This menu selection screen can be expressed in the form shown in FIG.
On this menu selection screen 110, the user who receives a search for common attribute information selects the “Execute attribute information search” button 112.

Next, some search end processes in the server 10 will be described.
In the server 10, as the first search end process, the use of the search PW can be prohibited when a predetermined time or a time set by the first user has elapsed.
FIG. 10 is a sequence diagram showing the flow of the first search end process in the server 10 according to the embodiment of the present invention.
First, in response to the server 10 issuing a search PW to the first user (see (30)), the server 10 temporarily stores the search PW issue time in association with the search PW ((31)). reference).
Thereafter, when a predetermined time or a time set by the first user has elapsed, the server 10 stores information on prohibition of use of the search PW in the search request reception information storage unit 2. As the use prohibition time of the search PW, for example, after the search result is notified to the first user terminal 20 and the second user terminal 30 (see (120)), the time is confirmed and the search PW is issued It is determined whether a predetermined time or a time set by the first user has elapsed, and when the time has elapsed, use of the search PW is prohibited (see (123A)). Accordingly, the server 10 subsequently checks the presence or absence of use prohibition information of the search PW with reference to the search request reception information storage unit 2 in response to reception of the search PW, and processes when there is use prohibition information. Exit.

  As a result, a flag prohibiting the use of the search PW is set in the search request acceptance information storage unit 2, and the search PW is valid only within a certain period of time.

Next, another search end process in the server 10 will be described.
In the server 10, as the second search end process, the use of the search PW can be prohibited when the communication connection with the first user terminal 20 is disconnected (logged out).
FIG. 11 is a sequence diagram showing the flow of the second search end process in the server 10 according to the embodiment of the present invention.
First, the server 10 receives a search PW issue request transmitted from the first user terminal 20 (see (20)), and confirms the communication connection status with the first user terminal 20 at regular intervals. (Refer to (21)).
Thereafter, when the server 10 determines that the connection with the first user terminal 20 has been disconnected, the search request acceptance information storage unit 2 stores information on prohibition of use of the search PW based on the identification information of the first user. . As the use prohibition period of the search PW, for example, after the search results are notified to the first user terminal 20 and the second user terminal 30 (see (120)), the communication connection status with the first user terminal 20 is indicated. If the connection is disconnected (logout), the use of the search PW is prohibited (see (123B)). Accordingly, the server 10 subsequently checks the presence or absence of use prohibition information of the search PW with reference to the search request reception information storage unit 2 in response to reception of the search PW, and processes when there is use prohibition information. Exit.

  As a result, a flag prohibiting the use of the search PW is set in the search request acceptance information storage unit 2, and the search PW is valid only while the first user is logged in.

Further, another search end process in the server 10 will be described.
The server 10 can prohibit the use of the search PW when the search end request is received from the first user terminal 20 as the third search end processing.
FIG. 12 is a sequence diagram showing the flow of the third search end process in the server 10 according to the embodiment of the present invention.
First, the processing until the server 10 notifies the first user terminal 20 and the second user terminal 30 of the search results (see (120)) is the same as the detailed processing flow described above.
Next, the first user terminal 20 transmits a search end request for requesting to end the search for the common attribute information to the server 10 (see (121)).
The server 10 receives the search end request transmitted from the first user terminal 20 (see (122)).
Then, the server 10 identifies the search PW associated with the first user ID included in the search end request, and stores the use prohibition information in the search request reception information storage unit 2 ((123C)). reference). The use prohibition time of the search PW is not limited to after the search result is transmitted as described above, but can be performed at any time such as before the search is performed. Accordingly, the server 10 subsequently checks the presence or absence of use prohibition information of the search PW with reference to the search request reception information storage unit 2 in response to reception of the search PW, and processes when there is use prohibition information. Exit.

  As a result, a flag prohibiting the use of the search request reception information is set in the search request reception information storage unit 2, and the search request reception information is valid until the first user sets the search end flag. It will be a thing.

Next, a search start process in the server 10 will be described.
In the server 10, as the search start process, the search process can be performed after confirming the first user who has requested the search for the common attribute information.
FIG. 13 is a sequence diagram showing the flow of search start processing in the server 10 according to the embodiment of the present invention.
First, the server 10 refers to the search request acceptance information storage unit 2 and specifies the first user ID associated with the search PW (see (100)). The same flow.

Next, the server 10 refers to the user information storage unit DB1 and identifies the contact information of the first user based on the identified user ID (see (101)).
The server 10 continues to confirm whether or not the second user and the attribute information may be compared with the first user terminal 20 based on the identified contact information of the first user. Is transmitted (see (102)).
The first user terminal 20 receives a message from the server 10. That is, when the first user notifies the second user of the search PW and the second user may perform a comparative search of the attribute information with the first user, a message asking for confirmation is displayed. Receive. This message is displayed on the display of the first user terminal 20 as an attribute information search execution confirmation screen.

This attribute information search execution confirmation screen can be expressed, for example, in the form shown in FIG. FIG. 22 is a diagram illustrating an example of the attribute information search execution confirmation screen displayed on the display of the first user terminal 20 connected to the server 10. This attribute information search execution confirmation screen 150 indicates that the second user has accepted the search for attribute information. “XXX (second user) has accepted the search for attribute information.” In addition to the message 141 for the first user, a “(Agree)” button 152 and an “(Agree)” button 153 are displayed. In addition, the attribute information search execution confirmation screen 150 displays a “Send” button 159 for sending a reply of intention display.
FIG. 22 shows a state in which the “(Agree)” button 152 is selected.

If the first user terminal 20 agrees to perform a comparison search of attribute information with the second user, the first user terminal 20 selects the “(Agree)” button 152 and selects the “Send” button 159.
As a result, a reply to the effect that the attribute information comparison search with the second user is agreed is transmitted to the first user terminal 20 (see (103)).
When the first user is requested to search for attribute information by a third party who does not remember the search PW, the first user selects the “(Agree)” button 153 and selects the “Send” button 159. By doing so, it is possible to refuse the search for the attribute information.

The server 10 receives an answer to the effect that it is agreed to perform a comparison search of attribute information with the second user transmitted from the first user terminal 20 (see (104)).
Then, the server 10 refers to the user information storage unit DB1, identifies the search target based on the identified first user ID and second user ID, the first user and the second user The attribute information is compared for each item (see (110)), and the search result is notified to the first user terminal 20 and the second user terminal 30 (see (120)).

  This suppresses the possibility that the search PW is used by an unknown third party of the first user and the attribute information of the first user is disclosed, and targets the second user who is convinced by the first user. Comparison search of attribute information can be performed.

  Note that the first user and the second user have not yet established a friendship, and after searching for attribute information, the first user establishes a friendship with the second user based on the matched attribute information. If desired, the first user uses the first user terminal 20 to specify the first user ID, the second user ID that identifies the second user desired by the first user, and the first user to the second user ID. A friend request requesting to establish a friendship with the user is transmitted to the server 10.

The server 10 refers to the user information storage unit DB <b> 1, specifies a contact address based on the received second user ID, and transmits a friend request request to the second user terminal 30.
When the server 10 continuously receives from the second user terminal 30 an agreement to agree to a friend request, the first user terminal sends a friendship construction notification to inform that the friendship has been formed with the second user. 20 is transmitted.
Then, the server 10 associates the first user ID and the second user ID with which the friendship is formed with each other and stores them in the user information storage unit DB1.

  Next, an example of detailed operation of the server 10 in the first embodiment as described above will be described with reference to FIGS. FIG. 23 is a flowchart showing the flow of search PW issue processing in the server 10. 24 and 25 are flowcharts showing the flow of search processing in the server 10.

First, the flow of search PW issue processing will be described.
As shown in FIG. 23, the search request first processing unit 11 uses the search request reception information issuance request receiving unit 11a to issue the first user ID transmitted from the first user terminal 20 and the search PW issuance request. Is determined (S11).

  As a result, when the search request first processing unit 11 receives the search PW issuance request (Y), the search request first processing unit 11 continues to the first user at the search request reception information issuing unit 11b. A search PW is issued (S12). In addition, the search request first processing unit 11 transmits information indicating that the search PW issuance request has been received and information indicating that the search PW has been issued to the search ending unit 15.

When the search end first instruction unit 15a receives information indicating that the search PW has been issued from the search request first processing unit 11, the search end unit 15 temporarily associates the search PW issue time with the search PW. (S13).
In addition, the search request first processing unit 11 associates the first user ID for which the search request acceptance information issuing unit 11b has issued a search PW request with the issued search PW in association with each other. It memorize | stores in the memory | storage part 2 (S14).
And the search request 1st process part 11 transmits the issued search PW to the 1st user terminal 20 in the search request reception information transmission part 11c (S15).
As a result, a series of operations in the server 10 ends (end).

  On the other hand, when the search request first processing unit 11 has not received a search PW issuance request (N), a series of operations in the server 10 is finished (end).

Next, the flow of search processing will be described.
As shown in FIG. 24, the search request second processing unit 12 receives the second user ID and the second user transmitted from the second user terminal 30 at the search request reception information receiving unit 12a. It is determined whether or not the search PW acquired from the user has been received (S21).

As a result, when the search request second processing unit 12 receives the search PW (Y), the search request second processing unit 12 continues to use the search request acceptance information availability determination unit 12b to determine whether the search PW is valid. It is determined whether or not (S22).
On the other hand, when the search request second processing unit 12 has not received the search PW (N), a series of operations in the server 10 is finished (end) as it is.
Here, whether the search PW is valid can be determined by, for example, the following three means.

  First, according to the issuance of the search PW in the search request first processing unit 11, the first means temporarily stores the issuance time of the search PW in association with the search PW. Next, when a predetermined time or a time set by the first user has elapsed, information on prohibition of use of the search PW is stored in the search request reception information storage unit 2. Then, when the search request second processing unit 12 receives the search PW, the search request second processing unit 12 refers to the search request reception information storage unit 2 and determines whether there is use prohibition information.

  Next, the second means confirms the communication connection status with the first user terminal 20 at regular intervals in response to the search request first processing unit 11 receiving the search PW issuance request. Next, when the connection with the first user terminal 20 is disconnected (logged out), information on prohibition of use of the search PW is stored in the search request reception information storage unit 2 based on the first user ID. Then, when the search request second processing unit 12 receives the search PW, the search request second processing unit 12 refers to the search request reception information storage unit 2 and determines whether there is use prohibition information.

  Further, when the third means receives a search end request from the first user terminal 20 together with the first user ID, the third means prohibits the use of the search PW based on the first user ID included in the search end request. Is stored in the search request acceptance information storage unit 2. Then, when the search request second processing unit 12 receives the search PW, the search request second processing unit 12 refers to the search request reception information storage unit 2 and determines whether there is use prohibition information.

  As a result of determining whether or not the search PW is valid, the search request second processing unit 12 determines that the search PW is valid (Y), that is, the search request acceptance information storage unit 2 is prohibited from use. When there is no information (flag), the first user specifying unit 12c refers to the search request acceptance information storage unit 2 and searches for and specifies the first user ID associated with the search PW ( S23). The search request second processing unit 12 transmits the identified first user ID to the common attribute item search unit 13.

  On the other hand, when the search request second processing unit 12 determines that the search PW is invalid (N), that is, when there is use prohibition information in the search request reception information storage unit 2, the subsequent processing is performed. finish.

<Second Embodiment>
Next, as a second embodiment, an outline of common attribute information search when a first user and a plurality of second users are grouped will be described with reference to FIG. In the present embodiment, the description will focus on the parts that are different from the first embodiment described above. Therefore, the description of the same components as those in the first embodiment is omitted, and is the same unless otherwise specified.
As shown in FIG. 26, the first user using the first user terminal 20 accesses the common attribute search site and requests the server 10 to issue a search PW as search request acceptance information (51 .reference). This search request acceptance information can be a one-time PW as in the first embodiment.
The server 10 receives the search PW issue request, issues the search PW, and transmits it to the first user terminal 20 (see 52). At this time, the search PW is stored together with the first user information of the transmission destination.

The first user terminal 20 receives the search PW, and the first user acquires the search PW (see 53.).
Next, the first user notifies the plurality of second users of the search PW by oral or electronic mail (see 54.).
A plurality of second users using the second user terminal 30 (A, B,... N) respectively access the common attribute search site and input the search PW acquired from the first user (see 55.). .

The server 10 receives the search PW from the second user terminal 30 (A, B,... N), respectively, and specifies the first user information based on the search PW (see 56).
Subsequently, the server 10 checks whether the first user terminal 20 may perform a common attribute search with a plurality of second users (see 57.).
The first user terminal 20 confirms a plurality of second users, and transmits a reply agreeing to conduct a common attribute group search with the second user to the server 10 (see 58.).
The server 10 performs a group search for attribute information common to the first user and the second user based on the agreement of the first user (see 59.).

Next, the server 10 notifies the first user terminal 20 and each of the second user terminals 30 (A, B,... N) of the information on the number of items of the common attribute obtained by the search (60. reference).
The 1st user terminal 20 acquires the information according to the number of items of the common attribute with the 2nd user from this server 10, and a 1st user browses (refer to 61A.), And each 2nd user terminal 30 (A , B... N) obtains information by the number of items of common attributes with the first user from the server 10, and each second user browses (see 61B.).

Next, the first user designates the user and desires to browse the common attribute information corresponding to the common attribute item, and the first user terminal 20 designates the user and requests the browsing of the common attribute information ( 62A.).
The server 10 receives the browsing request for the common attribute information from the first user terminal 20, and notifies the first user terminal 20 of the common attribute information with the designated user (see 63).
The first user terminal 20 acquires common attribute information with the designated second user from the server 10, and the first user browses (see 64A.).

On the other hand, the second user also designates the user and desires to view the common attribute information corresponding to the common attribute item, and each second user terminal 30 (A, B... N) designates the user. To request browsing of common attribute information (see 62A).
The server 10 receives a request for viewing common attribute information from each of the second user terminals 30 (A, B,... N), and notifies the corresponding second user terminal 30 of the common attribute information with the designated user. (See 63.).
The corresponding second user terminal 30 acquires the common attribute information with the first user from the server 10, and each second user browses (see 64B.).

  In this way, even in the case of a group, the information that you do not want to publish is not unnecessarily disclosed. Effectively build new friendships.

Next, a detailed example of the method executed as the second embodiment will be described with reference to FIG. FIG. 27 is a sequence diagram illustrating a processing flow of the common attribute information search method according to the second embodiment.
In the present embodiment, the first user terminal 20 connected via the communication network NW downloads the home page of the SNS service site and requests two search PWs obtained by requesting the issuance of the search PW from the home page. A case will be described in which attribute information common to the first user and the second user A and the second user B is searched for by notifying the second user.

First, the first user activates the first user terminal 20 and transmits a search PW issuance request to the server 10, and the first user terminal 20 receives the search PW transmitted from the server 10 (( The processing up to 60) is the same as the processing flow in the first embodiment described above.
Next, the first user notifies the second user A and the second user B who wish to search for the common attribute information for confirming the connection between the users by oral or e-mail or the like (see 70A). ).

The second user A and the second user B respectively obtain the search PW from the first user (see 70B-1 and 70B-2).
Each second user starts up the second user terminals 30A and 30B, connects to the server 10 via the communication network NW, and gives a user ID given in advance from the visited SNS service site, Enter the password set in, and log in.
Each second user transmits a search PW to the server 10 from the second user terminal 30A, 30B (see (80-1, 80-2)). During login, the user IDs of the second user A and the second user B are temporarily stored.

The server 10 receives the search PW transmitted from each of the second user terminals 30A and 30B (see (90)).

Become.

In the server 10, the number of common attribute items can be rearranged in order as the fifth search process.
FIG. 28 is a sequence diagram showing the flow of the fifth search process in the server 10 according to the embodiment of the present invention.
First, the server 10 performs a search for comparing the attribute information of the first user and the second user for each item (see (110)), and subsequently the server 10 compares the attribute information between users, The process until the common attribute item having the same attribute information is identified (see (111)) and the number of identified common attribute items is calculated for each user (see (112)) is the same as the process flow described above. The same.

Next, the server 10 rearranges the calculated number of common attribute items in order of size (see (113)).
Then, the server 10 notifies the first user terminal 20 and the second user terminal 30 of the number of common attribute items rearranged as a result of the search (see (120)).

At this time, the rearranged common attribute item number information is displayed on the display of the first user terminal 20 as a fourth attribute information search execution confirmation screen.
The fourth attribute information search result screen can be expressed in a form as shown in FIG. 33, for example. FIG. 33 is a diagram illustrating an example of a fourth attribute information search result screen displayed on the display of the first user terminal 20 connected to the server 10. In the fourth attribute information search result screen 170D, the first attribute information item “the number of common attribute information items between XXX” and each user is as follows. A common attribute item number order display column 171D for displaying the number of attribute items common to the user and the second user A, and the first user and the second user B is displayed. In FIG. 33, the first user and the second user B are displayed in the order of the number of matching attribute items, “10”, and the first user and the second user A are “8”. . The fourth attribute information search result screen 170D includes a “view attribute item” button 178D for displaying common attribute items and an “end” button 179D for ending work on the SNS service site.

In the attribute item information, a user ID may be transmitted to the server 10 by designating (selecting) a user, and an attribute item common to the corresponding user may be displayed based on the user ID.

  Further, the fourth attribute information search result screen displayed on the display of each second user terminal 30A, 30B can also be expressed in the form shown in FIG. 33, for example. At this time, the order of the number of common attribute items is that the second user A and the first user or the second user B and the first user, and the second user A and the second user B are displayed. Become.

  Next, an example of detailed operation of the server 10 in the second embodiment as described above will be described with reference to FIGS. 34 and 35. FIG. 34 and 35 are flowcharts showing the flow of search processing in the server 10 in the second embodiment. Note that the flow of the search PW issuance process in the server 10 in the second embodiment is the same as that in the first embodiment shown in FIG.

  First, as shown in FIG. 34, the search request second processing unit 12 receives the second user ID and the second user transmitted from the second user terminal 30 in the search request reception information receiving unit 12a. It is determined whether or not a search PW acquired from one user has been received (S51).

As a result, when the search request second processing unit 12 receives the search PW (Y), the search request second processing unit 12 continues to check whether the search PW is valid in the search request acceptance information availability determination unit 12b. It is determined whether or not (S52).
On the other hand, when the search request second processing unit 12 has not received the search PW (N), a series of operations in the server 10 is finished (end) as it is.
Here, whether the search PW is valid can be determined by, for example, the three means described in the first embodiment. Note that description of the three means is omitted.

  As a result of determining whether or not the search PW is valid, the search request second processing unit 12 determines that the search PW is valid (Y), that is, the search request acceptance information storage unit 2 is prohibited from use. When there is no information (flag), the first user specifying unit 12c refers to the search request acceptance information storage unit 2 and searches for and specifies the first user ID associated with the search PW ( S53). The search request second processing unit 12 transmits the identified first user ID to the common attribute item search unit 13.

  On the other hand, when the search request second processing unit 12 determines that the search PW is invalid (N), that is, when there is use prohibition information in the search request reception information storage unit 2, the subsequent processing is performed. finish.

The common attribute item search unit 13 specifies the contact information based on the first user ID by referring to the user information storage unit DB1 in the search execution confirmation unit 13a (S54).
The search request second processing unit 12 continues to transmit the second user ID from the second user terminal 30 and the search PW acquired by the second user from the first user at the search request reception information receiving unit 12a. It is determined whether there is any (S55).
As a result, when the search request second processing unit 12 has not received the search PW (Y), the common attribute item search unit 13 uses the search execution confirmation unit 13a to compare the second user and the attribute information. Is sent to the first user terminal 20 based on the identified contact information (S56).

  On the other hand, when the search request second processing unit 12 receives the search PW (N), the search request second processing unit 12 uses the search request acceptance information availability determination unit 12b to determine whether or not the search PW is valid. The determination process (S52) is repeated.

Next, the common attribute item search unit 13 receives an answer in the search execution confirmation unit 13a that agrees to perform a comparative search of attribute information with the second user transmitted from the first user terminal 20. It is determined whether or not (S57).
As a result, when the common attribute item search unit 13 receives an answer that the search is agreed (Y), the common attribute item search unit 13 determines the first attribute item specified by the common attribute item specification unit 13b. Based on the user ID and the second user ID, the user information storage unit DB1 is referred to, and a search for comparing the attribute information of the first user and the second user for each item is performed (S58).

On the other hand, if the common attribute item search unit 13 has not received an answer to the effect that the search is agreed (N), the series of operations in the server 10 is finished (end).
Subsequently, the common attribute item search unit 13 uses the common attribute item specifying unit 13b to specify common attribute items having the same attribute information (S59).

Next, when the common attribute item is specified, the common attribute item search unit 13 determines whether the common attribute item number calculation unit 13c has received an instruction to calculate the number of specified common attribute items for each user. Judgment is made (S60).
As a result, when the common attribute item search unit 13 receives an instruction to calculate the number of common attribute items for each user (Y), the common attribute item search unit 13 is identified by the common attribute item number calculation unit 13c. The number of common attribute items that have been set is calculated for each user (S61).

On the other hand, when the common attribute item search unit 13 has not received an instruction to calculate the number of common attribute items for each user (N), the common attribute item information identified as it is is transmitted to the search result transmission unit 14.
And the search result transmission part 14 transmits common attribute item information to the 1st user terminal 20 and the 2nd user terminal 30, respectively as a search result (S69).

Next, the common attribute item search unit 13 determines whether or not the common attribute item number order rearranging unit 13d has received an instruction to rearrange the calculated number of common attribute items in order of size (S62).
As a result, when the common attribute item search unit 13 receives an instruction to rearrange the number of common attribute items in order of size (Y), the common attribute item search unit 13 sets the common attribute item number order rearrangement unit 13d. Then, the calculated number of common attribute items is rearranged in order of size (S63).
Then, the common attribute item search unit 13 transmits the rearranged common attribute item number information to the search result transmission unit 14.
And the search result transmission part 14 notifies the number information of the common attribute item rearranged as a search result to the user terminal of each applicable user, respectively (S64).

On the other hand, when the common attribute item search unit 13 has not received an instruction to rearrange the number of common attribute items in order of size (N), the common attribute item search unit 13 then determines the common attribute item number ratio The calculation unit 13e determines whether an instruction to calculate the ratio of the calculated number of common attribute items has been received (S65).
As a result, when the common attribute item search unit 13 receives an instruction to calculate the ratio of the number of common attribute items (Y), the common attribute item search unit 13 uses the common attribute item number rate calculation unit 13e. The ratio of the number of common attribute items to the number of all items compared is calculated (S66).
Subsequently, the common attribute item search unit 13 transmits the calculated ratio information of the number of common attribute items to the search result transmission unit 14.
And the search result transmission part 14 transmits the ratio information of the number of common attribute items to the 1st user terminal 20 and each 2nd user terminal 30A, 30B as a search result, respectively (S67).

On the other hand, if the common attribute item search unit 13 has not received an instruction to calculate the ratio of the number of common attribute items (N), the common attribute item number information calculated as it is is transmitted to the search result transmission unit 14.
And the search result transmission part 14 transmits the number information of a common attribute item to the 1st user terminal 20 and each 2nd user terminal 30A, 30B as a search result, respectively (S67).

Next, the common attribute item search unit 13 determines whether or not the common attribute item specifying unit 13b has received an instruction to display the corresponding common attribute item (S68).
As a result, when the common attribute item search unit 13 receives an instruction to display the common attribute item (Y), the common attribute item search unit 13 transmits the identified common attribute item information to the search result transmission unit 14 as it is. .
Then, the search result transmitting unit 14 transmits the common attribute item information to the first user terminal 20 and the second user terminals 30A and 30B as the search results (S69).
On the other hand, when the common attribute item search unit 13 has not received an instruction to display the common attribute item (N), a series of operations in the server 10 is finished (end) as it is.

Next, the common attribute item search unit 13 determines whether or not the attribute information extraction unit 13f has received an instruction to display attribute information corresponding to the specified common attribute item (S70).
As a result, when the common attribute item search unit 13 receives an instruction to display attribute information (Y), the common attribute item search unit 13 corresponds to the common attribute item specified by the attribute information extraction unit 13f. The attribute information is extracted for each user, and the extracted attribute information is transmitted to the search result transmission unit 14.
And the search result transmission part 14 transmits attribute information to the 1st user terminal 20 and each 2nd user terminal 30A, 30B as a search result, respectively (S71).
As a result, a series of operations in the server 10 ends (end).
