Description

  The present invention relates to a technique for transmitting data via a network, and more particularly to control of access to data via a network.

  With the spread of the Internet, CGM (Consumer Generated Media) sites such as blogs, SNS (Social Networking Services), BBS (Electronic Bulletin Board, Bulletin Board System), and word-of-mouth sites are widely used by people. The CGM site is a site that allows a number of general users to view information transmitted by general users for non-commercial purposes via the Internet.

  For example, in general, a blog is a site where a blog administrator's personal experience, diary, impressions about a specific topic, etc. are recorded in a time series, and can be viewed by any general user via the Internet. That means. Some blogs accept writing of comments from browsing users on information sent from the blog administrator.

  In addition, for example, in general, SNS means that general users who have some kind of connection such as hobbies, residential areas, home schools, and common friends have registered as members, and various information among registered general users. A site that can be exchanged.

  There is also a CGM site called a diary site that combines blogs and SNS. At the diary site, only the person who writes or the specific person authorized by the person can view the person's diary. In other words, in a diary site, access to information that a site administrator writes every day in the same way as a blog can be restricted only to specific members as in the case of SNS.

  Non-Patent Document 1 is an example of a non-patent document showing an example of a diary site. Non-Patent Document 1 states that “In Hatena Diary, you can change your diary to private (private) mode and make it read only to specific people you want to publish. Your family, relatives, company colleagues, etc. Please use it when you want someone who knows your private information to view your private diary. "

Hatena Co., Ltd. “Hatena Diary Help“ Make Your Diary Private ””, [online], [Search September 21, 2009], Internet <URL: http://hatenadiary.g.hatena.ne.jp/ keyword /% E6% 97% A5% E8% A8% 98% E3% 82% 92% E3% 83% 97% E3% 83% A9% E3% 82% A4% E3% 83% 99% E3% 83% BC % E3% 83% 88% E3% 81% AB% E3% 81% 99% E3% 82% 8B>

  The information stored in the CGM site is information that shows the daily trivial thoughts and ideas of general users who have transmitted information on the CGM site, and is non-fiction information compared to movies, dramas, novels, etc. . Therefore, the information accumulated in the CGM site is a record of the mind of the general user who wrote down the information, and is also a representation of the social aspect that strongly reflects the era and social environment, and the general who simply browsed the CGM site This information can be a valuable memory for the user.

  Such information may be something that you want to keep only in the mind of the person who wrote it down, or something that you do not want to be known by anyone other than a specific person. If the blog mechanism with private settings disclosed in Non-Patent Document 1 described above is used, the blog site can be browsed only by the site manager himself, or can be opened only to a specific family member or acquaintance.

  As mentioned above, some of the information that the site administrator wants to keep secret for all people or non-specific people includes the specific information that the site administrator has kept secret as time passes and the situation changes. Some information changes that people want to see.

  For example, suppose that a teacher of an athletic club member's advisor and director uploads a photograph of a member taken every day together with a comment to a private diary site where only himself can view and write. And while the teacher strictly teaches the member as a demon director, he writes the inner thoughts about each member on the diary site.

  Demon Director's inner thoughts should not be known to those members while they are active. However, when a member retires from active duty due to graduation, etc., there is no problem even if they are known to the member, but rather if the member is told what kind of thought the demon coach was teaching the member, Misunderstandings between teachers and members that may have occurred in the times may be resolved, and the trust relationship between the teachers and students built in the active era may be further strengthened. In addition, the information on the diary site may be helpful when the staff is instructing people in some way in the future.

  Therefore, it is desirable that the demon director's diary site prohibits the viewing of those members while the members are active, and allows the members to be permitted to view after the members retire. However, in the case of the conventional technique, it is necessary for the site manager to manually and forbid prohibition or permission for browsing, and this is troublesome. In particular, when granting browsing permission to people who have been banned after a long period of time, the site administrator forgets the work and misses the chance to do the work in a busy time. This is not desirable.

  In view of the above-described circumstances, the present invention provides means for making information that has been kept secret to a specific person available to that specific person on the CGM site on the Internet according to the passage of time or changes in the situation.

[1. Embodiment]
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments that are specific examples of the present invention will be described below with reference to the drawings.

[1.1. Constitution]
FIG. 1 is a diagram showing an overall configuration of a system 1 according to an embodiment of the present invention. The system 1 is a system that provides various CGM sites such as a blog, an SNS, a BBS, a still image / video sharing site, and a word-of-mouth site.

  The system 1 stores site content, transmits content to a terminal device in response to a browsing request from a terminal device used by a user of the system 1, and adds data to the content in response to a write request. And a terminal device 12 used by a user of the system 1. There are as many terminal devices 12 as the number of users of the system 1, and the number varies in various ways.

  Each of the terminal devices 12 can perform data communication with the server device 11 via the network 21. The network 21 is an aggregate of networks in which the Internet and other networks such as a LAN (Local Area Network) and a mobile communication network are connected to each other.

  The terminal device 12 is a general personal computer, a mobile phone or the like having a browser function and a mailer function, and the description of the configuration is omitted.

  The server device 11 is realized, for example, by causing a personal computer having a function of performing data communication with the terminal device 12 via the network 21 to execute processing according to the application program according to the present invention. However, instead, the server device 11 may be realized as a so-called dedicated machine by a collection of hardware that performs processing of each component described below, for example.

  FIG. 2 is a diagram illustrating a functional configuration of the server device 11. The server device 11 has, as its functional components, a storage unit 111 that stores various data, and browsing of content on a site or writing to the content (hereinafter collectively referred to as “access to content”). A scope changing unit 112 that changes a scope that is a range of permitted users, a time measuring unit 113 that outputs current time data indicating the current time in response to a request from the scope changing unit 112, and other devices via the network 21 A receiving unit 114 that receives data transmitted from the network, a transmitting unit 115 that transmits data to other devices via the network 21, and a notification that sends an e-mail notifying that the scope has been changed to the network 21. Part 116.

  In addition, the server device 11 authenticates the user of the device that requests access to the content, and the user authentication unit 117 performs authentication of the user based on the scope. And an access control unit 118 that controls access.

  The scope changing unit 112 includes a determination unit 1121 that determines whether a condition indicated by condition data included in a scope determination data group (described later) stored in the storage unit 111 is satisfied. The scope changing unit 112 changes the current scope to the post-change scope indicated by the scope data included in the scope determination data group when the condition is satisfied according to the determination result of the determination unit 1121.

  The timer 113 periodically acquires current time data indicating the current time from, for example, a clock server device (not shown) via the network 21 and constantly measures an elapsed time from the reference time. Upon receiving a request from the scope changing unit 112, the time measuring unit 113 calculates the current time by adding the elapsed time from the acquisition time of the current time data to the time indicated by the current time data acquired from the clock server device. The current time data indicating the calculated current time is delivered to the scope changing unit 112. Note that the configuration and operation of the time measuring unit 113 described above are examples, and the generation of the current time data may be performed by any other configuration or method.

  When the user ID and password input by the user of the terminal device 12 and transmitted from the terminal device 12 are received by the receiving unit 114, the personal authentication unit 117 stores a record including the combination of the user ID and password. When the search is successful, the user of the terminal device 12 is authenticated as the user identified by the user ID.

  When the browsing request data for requesting browsing of content is received from the terminal device 12 by the receiving unit 114, the access control unit 118 determines that the user of the terminal device 12 identified in the authentication by the personal authentication unit 117 has the current scope. It is determined whether or not the user is in a browsing scope that is a scope related to browsing. When the access control unit 118 determines that the user of the requesting terminal device 12 is in the browsing scope, the access control unit 118 instructs the transmission unit 115 to transmit the requested content data to the terminal device 12. If it is determined that it is not in the browsing scope, the transmission unit 115 is not instructed to transmit the requested content data, and for example, the terminal device 12 is instructed to transmit a notification that access is not possible.

  Similarly, when the write request data requesting writing to the content is received from the terminal device 12 by the receiving unit 114, the access control unit 118 of the terminal device 12 identified in the authentication by the personal authentication unit 117. It is determined whether or not the user is in a writing scope that is a writing scope of the current scope. If the access control unit 118 determines that the user of the requesting terminal device 12 is in the write scope, the access control unit 118 instructs the storage unit 111 to write additional data to the requested content data. On the other hand, if it is determined that it is not in the writing scope, it is not instructed to write additional data to the storage unit 111, and the transmission unit 115 is instructed to transmit to the terminal device 12 a notification that access is not possible, for example. .

  The storage unit 111 stores a user attribute DB that stores user attribute data indicating user attributes for each registered user registered as a user of the system 1. In addition, in each of the plurality of sites provided in the system 1, the storage unit 111 includes content data indicating the content of the site and a scope determination data group that is data for determining the scope of the site. It is stored in association with each other.

  FIG. 3 is a diagram showing the configuration of the user attribute DB. The user attribute DB is a collection of a plurality of records each corresponding to a registered user, and each record includes user authentication data for performing user authentication and user attribute data indicating various attributes of the user.

  The user authentication data includes a user ID (Identifier) and a password, and the user ID is a user's mail address. Instead of the user ID also serving as a mail address, a user ID different from the mail address may be used, and the mail address may be associated with the user ID and stored in the user attribute DB.

  The user attribute data includes a field for storing data indicating various attributes such as “gender”, “birth date”, “marriage”, “presence / absence of children”, etc. as subfields. The user of the terminal device 12 who has been authenticated by the user ID and password can change user attribute data indicating his / her attributes. For example, when a user who has no children has a child, the user can change the “presence or absence of children” of his / her user attribute data from “none” to “present”. The method of changing is the same as the method of changing user information at a normal site, and therefore the description thereof is omitted.

  The content data corresponding to each site stored in the storage unit 111 differs depending on the type of site, but since all are the same as the conventional one, the description thereof is omitted.

  FIG. 4 is a diagram illustrating a configuration of a scope determination data group stored in the storage unit 111 in association with each site, that is, in association with each content data. The data shown in FIG. 4 is for the third-year member (29th-year member) who is a student of a high school basketball team called Ichitaka who graduates this year among the members who are students. This is data relating to a still image / moving image sharing site for storing a photograph (still image) and a video (moving image) recording an activity together with a comment.

The scope determination data group includes the following data.
Site ID: Site identifier.
Site description: Description of the site. Indicates the title of the site.
Administrator ID: User ID of the site administrator.
Content type: Indicates whether the content included in the site is “still image / moving image sharing”, “blog”, “SNS”, “BBS”, “word-of-mouth site”, or the like.
Site URL: Indicates a URL (Uniform Resource Locator) for accessing the site.
Current scope: Scope data indicating the scope currently in effect. One of “original scope”, “sleeping”, “scope after change”. Note that “sleeping” means a special scope that does not allow any user access.

Original scope: Scope data indicating the scope at the time of site creation.
Scope change condition: Condition data indicating a trigger condition for changing the scope to the scope after the change when the current scope is “original scope” or “sleeping”.
Scope after change: Scope data indicating the scope adopted after the scope change condition is satisfied.
Notification message: Indicates a message that should be included in a notification sent to a user's email address that is newly included in the browsing scope due to a change in scope.

  The scope data indicating each of the original scope and the post-change scope includes a user ID group of a user who permits browsing indicating a browsing scope and a user ID group of a user who permits writing indicating a writing scope. These user IDs include registered user IDs, ie, user email addresses registered in the user attribute DB, and non-registered user email addresses, ie, user email addresses not registered in the user attribute DB. May be included.

  In order to distinguish between the user ID of the registered user and the user ID of the non-registered user, (s) is appended to the user ID of the registered user. This (s) indicates that the server device 11 is registered in the user attribute DB when a change is made to the original scope and the post-change scope, or when a user is newly registered in the user attribute DB (see FIG. 3). It is automatically added by comparing the e-mail address with the e-mail address included in the original scope or the changed scope.

[1.2. Operation]
Subsequently, the operation of the system 1 will be described. However, the operation of the system 1 is compared with a conventional CGM site providing system, triggered by an instruction manually performed by the site administrator or when a condition set in the scope determination data group is satisfied in advance. It is characterized in that the scope is changed. Therefore, the following description will be made mainly on that point, and the description of operations common to the conventional system will be omitted.

[1.2.1. First case]
As a first case, how the scope is changed for the still image / video sharing site associated with the scope determination data group shown in FIG. Explain how it will go. First, as shown in FIG. 4, it is assumed that the current scope is the original scope. Each of the browsing scope and the writing scope of the original scope includes only the email address of the teacher who is the site administrator of this site. Therefore, this site is now a completely private site that is only accessible by site administrators. This is because the 29th grader of the Ichitaka Basketball Club, which is the subject of recording on this site, is still active as an active member.

  As the scope change condition of the scope determination data group of this site, “when it is March 20, 2010” is set. This data instructs to change the current scope to the scope after the change when the current time is 0:00 on March 20, 2010. March 20, 2010 is the day following the day of the graduation ceremony, and the site administrator sets the scope change condition in advance so that the day becomes the day of the scope change.

  In the post-change scope of the scope determination data group of this site, the mail address of the site manager and the mail addresses of all the basketball members in the first 29th grade are registered as the browsing scope. A person with a member is a registered user, and a person is a non-registered user. The site administrator has e-mail addresses from each member and has registered them in the browsing scope in advance. Note that it is not necessary for the site administrator to check whether each email address belongs to a registered user or a non-registered user. As already described, (s) for distinguishing them is automatically added by the server device 11.

  In the post-change scope of the scope determination data group of this site, “nobody” meaning that no user is permitted is registered as a writing scope.

  The site administrator sets the scope determination data group as described above at the time of site generation or without much time after the site generation, and thereafter, the server device 11 stores data indicating photos and videos and comments on them daily. By uploading to, we will increase the content of the site.

  Later, when third graders retired from club activities and began to concentrate on university entrance exams and job hunting activities, site administrators rarely updated this site, and this site eventually faded from the site administrator's awareness. Go.

  On the next day when the third grader graduates, the determination unit 1121 included in the scope change unit 112 of the server device 11 determines that the scope change condition of the scope determination data group is satisfied. According to the result of the determination, the scope changing unit 112 changes the data in the “current scope” column of the scope determination data group to “scope after change”.

  Along with the change of the current scope by the scope changing unit 112, the notification unit 116 extracts mail addresses that are not included in the browsing scope before the change but are included in the browsing scope after the change. In this case, all e-mail addresses excluding the e-mail address of the site manager among e-mail addresses included in the changed browsing scope, that is, e-mail addresses of all basketball members in the first 29th grade are extracted.

  The notification unit 116 follows the data registered as a notification message in the scope determination data group addressed to the mail address of the registered user, that is, the mail address extracted as described above with (s) added, that is, the registered user's mail address. , "Oni Director Taro Yamada has a nice (?) Present for the first 29th grader's former basketball club! If you want a present, go to http://ichiko_basketballclub_29kisei.sakigakecgm.com/ now!" Generate an email containing a message.

  In addition to the above message, the notification unit 116 sends, for example, “this message” to the e-mail address extracted as described above, to which the (s) is not added, that is, to the e-mail address of the unregistered user. In order to access the site you have been invited to, you need to register as a user. To register, please visit http://userregistration.sakigakecgm.com/ now. " Generate.

  The notification unit 116 delivers the electronic mail generated as described above to the transmission unit 115 and sends it to the network 21.

When each of the former 29th grader's former basketball club members received a message from the teacher of the basketball club advisor by e-mail the day after the graduation ceremony, if they were already registered users, they would log in to the server device 11 as usual. And was notified by email
You can access http://ichiko_basketballclub_29kisei.sakigakecgm.com/.

If you are not yet a registered user, the former basketball club member will access http://userregistration.sakigakecgm.com/ notified by e-mail, and after completing user registration,
You can access http://ichiko_basketballclub_29kisei.sakigakecgm.com/.

  Any existing method may be adopted as the method of user registration. For example, the user registration request data including the user attribute data of the user who receives the registration and the password that the user who receives the registration decides by himself / herself is transmitted from the terminal device 12 to the server device 11. A method may be employed in which the included password is registered in the user attribute DB together with the user attribute data. Also, user registration request data including user attribute data is transmitted from the terminal device 12 to the server device 11, and a password is generated according to the user registration request data in the server device 11, and the generated password is used as the user registration request data. In addition, a method may be employed in which the server device 11 notifies the terminal device 12 of the generated password while being registered in the user attribute DB.

  As a result of the above, former basketball club members can know the thoughts of their advisors in their daily activities. In this way, the records accumulated by the advisor's teachers on a daily basis become messages from the teachers who are more realistic for the members, compared with messages that are written by relying on memory in about one or two days.

  As described above, according to the system 1, the site manager can gradually accumulate messages that he / she wants to convey to the future in his daily life. In addition, by setting the timing at which you want to communicate as a scope change condition in advance, you can avoid the danger of missing the timing to convey a message because you forget the arrival of that timing or are busy at that timing can do. As a result, users who are site managers can communicate the daily trivial, but reality-filled thoughts that were previously difficult to convey to their desired people.

[1.2.2. Second case]
As a second case, a state in which the scope of the blog site provided for the purpose of exchanging information related to child-rearing by parents releasing their daughter's growth diary will be described in the system 1 will be described.

  FIG. 5 is a diagram showing a scope determination data group of this site. The current scope of this site is "sleeping". This is because, as the daughter grows, the site administrator's parents update the site less frequently, so the daughter becomes a junior high school student, and the server device 11 is set to do so. It is because it went. As a result, no one, including the site administrator's parents, can view the content of this site or make new entries on this site, and for general users this site is a closed site. Recognized.

  This site will be viewed by any user (including non-registered users) and written by any user (but censored by the site administrator), according to the original scope, before the daughter was hibernated. Was allowed. And the contents of the blog that the parents who are site administrators wrote every day and the comments written by various readers on the contents are accumulated.

  In the scope determination data group of this site, the scope change condition is “User ID: chihiro_k@mail.co.jp (s) attribute: When the presence or absence of a child is changed from none to yes, or April 2030 “When it is the first day” is set, and the daughter's email address chihiro_k@mail.co.jp (s) is registered in the browsing scope of the changed scope.

  When the content of the user attribute DB is changed, the determination unit 1121 included in the scope change unit 112 changes the scope change condition included in the scope determination data group of each site in light of the content of the user attribute DB after the change. It is determined whether or not the condition is satisfied. The determination unit 1121 receives current time data from the time measuring unit 113 at a predetermined time interval, for example, every hour, and the scope change condition included in the scope determination data group of each site is indicated by the received current time data. In light of the current time, it is determined whether or not it has been newly satisfied.

  Therefore, in the case of this site, in the future, this daughter will have a child, and in the user attribute data registered in the server device 11, the “presence / absence of child” will be changed from “none” to “present”, or When the user attribute data is not changed as of April 1, 2030, the determination unit 1121 determines that the scope change condition is satisfied. According to the determination result, the scope changing unit 112 changes the current scope from “sleeping” to “scope after change”.

  Along with the change of the current scope by the scope changing unit 112, the notification unit 116 extracts the daughter's email address as an email address that is not included in the browsing scope before the change but is included in the browsing scope after the change. An e-mail including a message set in the scope determination data group is generated as a notification message addressed to the e-mail address, and the generated e-mail is delivered to the transmission unit 115 and transmitted to the network 21.

  My daughter may or may not have visited the site when it was still open. You may have known the site, or you might not have known it at all. In any case, the e-mail sent from the server device 11 becomes a surprise message from the parents for the daughter.

  And the daughter who visited this site, how the parents grew up in the past, how they responded to various problems and difficulties that occurred during child rearing, and general You can get information on how your blog readers thought. It is information that shows the real feelings of parents and the people who watch them, as well as information that can be a valuable guide for daughters to raise their children.

[1.2.3. Third case]
As a third case, for a man and woman who are planning to marry (hereinafter referred to as “the groom” and “the bride” for the sake of convenience throughout the marriage) The manner in which the scope of the SNS site provided for the purpose of sending a blessing message is changed in the system 1 will be described.

  FIG. 6 is a diagram showing a scope determination data group of this site. The current scope of this site is the original scope, and the email address of the groom / bride acquaintance / friend is registered in both the browsing scope and the writing scope. A new registered user can be added to the browsing scope and the writing scope by introducing a registered user already registered. This is the same as the referral system adopted by many SNS sites. Therefore, the site administrator only has to register several brides and grooms acquaintances and friends when the site is launched.

  On this site, acquaintances and friends of the bridegroom and bride can talk about the memories of the bridegroom and bride, for example, and those who have previously married can give advice from their experiences and write freely. . However, messages that deviate from the purpose of blessing are deleted without being disclosed at the discretion of the site administrator.

  In the scope determination data group of this site, “when it is October 3, 2009” is set as a scope change condition. This is a week after the wedding. Site administrators can immediately write a message so that those who attend a wedding, its reception, or a second party can write their impressions, and those who fail to attend the wedding can rush to write messages. Rather, we will send the messages accumulated on this site to the bride and groom one week later.

  Therefore, when the wedding is held and one week has passed thereafter, the current scope of this site is changed from the “original scope” to the “post-change scope”. In the post-change scope, the mail address of an acquaintance / friend and the mail address of the groom / bride are registered as the browsing scope, and only the mail address of the groom / bride is registered as the writing scope. Therefore, after a week has passed since the wedding, writing of new messages by acquaintances and friends is closed.

  Similar to the first case and the second case, an e-mail including a message set as a notification message is transmitted to the groom / bride e-mail addresses as the scope is changed. The groom and the bride will follow the email message and visit the site to read the message written by their acquaintance / friend. A response message to the message can be written at the site.

[2. Modified example]
The above-described embodiments are examples for explaining the present invention, and various modifications are possible within the scope of the technical idea of the present invention.

  For example, in the above-described embodiment, when the user attribute DB is updated, the scope changing unit 112 sequentially reads out the scope determination data groups regarding all the sites, and updates the user attribute DB among the scope change conditions included in them. Although the search was made for a condition that was newly satisfied, such a configuration is not efficient as the number of sites increases.

  Therefore, for example, when a scope change condition is added to the scope determination data group, the site ID of the scope determination data group is registered in the user attribute DB record related to the added scope change condition, and the user attribute DB is registered. When the update is performed, it is desirable that only the scope determination data group of the site ID registered in the updated record is checked, so that the scope change process is efficiently performed even if the number of sites increases.

  In the above-described embodiment, one scope change condition and one after-change scope are provided. However, a plurality of scope change conditions and a post-change scope corresponding to each of the scope change conditions may be set. When such a configuration is adopted, the scope can be changed more flexibly.

  In the above-described embodiment, the notification means associated with the change of scope is based on electronic mail, but is not limited thereto. For example, a configuration may be adopted in which phone numbers of mobile phones of those users are registered and notification is made by sending a voice message to these phone numbers by automatic voice.

  In the above-described embodiment, the handling of content data of a sleeping site is not particularly described. However, the sleeping site and the content data are automatically compressed, and the content data is automatically converted when the sleeping state is released. A configuration in which the data is decompressed may be adopted. In addition, the content data of the hibernated site is automatically moved to another storage device different from the storage unit 111 that is not permitted to be accessed from the terminal device 12, and automatically from the storage device when the sleep state is released. A configuration in which content data is re-moved to the storage unit 111 may be employed. In either case, the storage capacity of the storage unit 111 of the server device 11 can be used effectively.

  In the above-described embodiment, the users included in the scope are specified in units of users. For example, it is possible to specify in units of user groups in which a plurality of users are grouped, or to specify them by mixing them. Good. Further, for example, it may be possible to refer to the scope of another site.

  For example, there is an SNS site used by teachers who have taught a certain grade to exchange information. In addition, there is an SNS site for students of that grade to exchange information, and the SNS site is continuously used as an alumni association site even after students graduate. Then, suppose teachers want to send their SNS site content as a surprise message to adult students.

  In such a case, the site manager of the SNS site of the teachers is set to refer to the browsing scope of the SNS site of the student instead of registering the email address of each student as the browsing scope of the changed scope. It is convenient if possible. That way, on the day of adulthood, students registered on the alumni site will receive e-mails, and those students will be able to view the content of the SNS site of teachers who have already become dormant logs and have fallen asleep. Become.

  In the above-described embodiment, the combination of the user ID and the password is used as the user authentication data. However, this is an example, and other user authentication data may be adopted. For example, feature data indicating biometric features for performing biometric authentication such as fingerprint authentication may be employed as the user authentication data. In this case, the server device 11 performs personal authentication by collating the feature data transmitted from the terminal device 12 with the feature data registered in the user attribute DB. A public key issued by a trusted third party may be adopted as user authentication data. In that case, the server device 11 authenticates the user by decrypting the encrypted data (encrypted with the secret key) transmitted from the terminal device 12 with the public key registered in the user attribute DB. become.

  The present invention can be used by all business operators who provide means for publishing or exchanging information via a network, and all business operators who use other business services.
