Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic information service method, a computer, and a storage medium for providing a service of providing electronic information to members using a network such as the Internet.

[0002]

2. Description of the Related Art Generally, when providing electronic information only to members on the Internet, a user is required to register once, and the member information obtained from the user is stored in a database. In addition, it is essential that members have a mechanism to authenticate members based on information in the database when using services.

[0003] The member information held in the database includes, for example, authentication information such as a user name and a password, as well as personal information such as an address, a name, and a telephone number. Appropriate or inadequate use could result in unauthorized use of services by non-members, leakage of personal information, and the like.

Therefore, in order for a service provider to provide an information providing service for members using the Internet,
It is necessary to maintain and manage member information sufficiently.

On the other hand, in recent years, in order to reduce costs, service providers use, for example, application service providers (hereinafter, referred to as ASPs) to create partial contents of member services and operate sites. We may ask other companies or other departments.

[0006] Part of the information provision service for members is ASP
In the past, ASPs conventionally need to receive member information from a service provider for member authentication.

[0007]

However, as described above, the member information is extremely confidential information, and the member information itself or the access method thereof is changed to another company or the access method just because it is necessary for the member authentication. Providing it to other departments involves the risk of information leakage, so it is a matter that the service provider should avoid if possible.

[0008] Further, the contractor who provides a part of the member information providing service must be responsible for maintaining and managing the information when the member information and the access method are provided from the service provider. Exchange of member information is a matter to be avoided.

[0009] The present invention has been made to solve such a problem, and all of the member information held by a service provider that provides an information providing service for members can be converted by a side constructing a Web site related to this service. An object of the present invention is to provide an electronic information service method, a computer, and a storage medium that can construct a website for members who cooperate with each other without receiving the information.

[0010]

In order to achieve the above object, an electronic information service method according to the first aspect of the present invention is an electronic information service method for publishing electronic information to members on a network. A step of judging whether or not a user who has requested access to a first web server connected to a network can log in to the first web server by performing member authentication based on member information held in a database; And a step of recognizing through which route or procedure the user who has requested access to the second web server connected to the network has requested access to the second web server. An access request was made to the second web server after logging in to the first web server through member authentication. It is characterized by having the steps of allowing access to the second web server to the case.

According to a sixth aspect of the present invention, there is provided a computer for publishing electronic information to a member on a network, wherein the user accesses the network based on an access request from the user received through the network. Recognition means for recognizing what route or procedure the user has requested access to, and recognition results by the recognition means. When the user requests access after logging in to a predetermined computer on the network, access to the user is performed. Permission means.

A storage medium according to a seventh aspect of the present invention is a storage medium storing a program for causing a computer for publishing electronic information to members on a network to execute a process, wherein the program is received by the computer via the network. Based on the access request, the user is made aware of what route or procedure on the network the user has requested access to, and as a result of this recognition,
When the user makes an access request after logging in to a predetermined computer on the network, the computer readablely stores a program for permitting access to the user.

According to the present invention, when an access request from a user is received by a computer via a network, the user recognizes what path or procedure the user has made an access request on the network, and as a result of the recognition, the user recognizes that Since access to itself is permitted when an access request is made after logging in to the above predetermined computer, this computer does not need to hold member information for authenticating a user.

That is, in the case of the present invention, a user first requests access to a member service of a computer (first web server) holding member information, and receives membership authentication.

Next, the user makes an access request to a computer (second web server) that provides a service having no member information with Web-related functions provided in the member service.

The destination computer (second web server) that has received the access request determines whether the user who has made the access request is a user who has moved from a correct place (a service provided by the first web server). Or recognize
If you're moving from the right place, grant access to yourself to provide services, otherwise deny access.

Also, the first time or once every certain period,
We asked them to move from a service that authenticates members to a service that does not have member information.
By performing authentication and providing services for members,
A user who no longer has access to the web server can be prevented from continuing to receive the service provided by the second web server.

Further, when moving from a service for performing member authentication, a part of the member information, for example, a member ID, is provided as additional information, and is used for an additional service for identifying individual members. The service provider can know the preferences of individual members.

In order to recognize that the user who has logged in to the first web server has moved to the second web server, use is made of header information included in an access request in the hypertext transfer protocol, or It is conceivable that the keywords decided by the first and second web servers are added to the link of the page and used.

When operating a site for members on the Internet, as part of the service for members, an information disclosure site (additional service) that does not cause much harm even if it is illegally used by a user other than the member is considered. May increase.

At the time of such site enhancement, a service provider that operates a site for members operates a new site (a first web server) that performs additional services separately from a site (a first web server) that operates directly. In many cases, the construction of the second web server is requested to another company.

In such a case, by using the present invention, a company that constructs a system for a new site (second web server) can obtain a new site (second web server) without receiving member information from a service provider. (A second web server).

In other words, all the member information held by the service provider that provides a member information providing service by constructing a certain Web site is linked to each other without receiving the member who constructs the Web site related to this service. A Web site for members can be constructed.

[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a system configuration (electronic information service system) of a first example for realizing the electronic information service method of the present invention.

As shown in FIG. 1, the electronic information service system includes a plurality of Webs connected to the Internet 5.
b. Access requests are made to the b servers 1 and 2 and these web servers 1 and 2, and when access is permitted, the web server
Multiple Webs that can view information published by 1,2
b terminals 3 and 4.

The Web server 1 includes a service information database 13 storing information on the service A (a home page and various pages linked thereto), and a hypertext transfer for publishing a site including the information on the service A on the Internet 5. Protocol server software 11
(Hereinafter referred to as HTTP server software 11) and this service A
And member authentication software 12 for authenticating members who can use.

The Web server 2 includes a service information database 23 storing information on the service B (a home page and various pages linked thereto), and an HTTP for publishing a site including the information on the service B on the Internet 5.
Server software 21 and access method determination software 22 that determines whether or not the user has made an access request to this site after logging in to the Web server 1 and permits access to this site only in that case. .

The Web terminals 3 and 4 are provided with browser software 31 and 41 for displaying various information (including information on services A and B) published on the Internet 5. The Web terminal 3 is a terminal used by the member user himself. The Web terminal 4 is a terminal used by general users.

The service A is a security system in which the user who has made an access request based on the member information registered in the service information database 13 is authenticated as a member to determine whether or not the member is a member, and then the login is permitted and the information is disclosed. (E.g., financial related online trading services such as stock trading, savings, etc.).

The service B is a service for providing information to the members of the service A in a form added to the service A. Information which does not cause much harm even if a user other than the member misuses the service B, For example, it discloses stock market conditions and news.

That is, the member information is held in the Web server, and the service for performing authentication for each user who wants to access the server is provided by the service A or the Web.
Service B is a service that can be used by members without holding member information on the server.

Hereinafter, the operation of the electronic information service system will be described. In this embodiment, an example will be described in which an HTTP server (Web servers 1 and 2) on the Internet 5 is used as one of the member information services.

In the case of this electronic information service system, the member user accesses the Web server 1 using the browser software 31 running on the Web terminal 3, receives the member authentication, and obtains the information of the member service A. Browse.

When the browser software 31 makes an access request to the Web server 1, a dialog box 51 for prompting the user to input a user ID and a password is displayed as a top page of the service A as shown in FIG. .

Here, when the user inputs his / her user ID and password, the member authentication software 12 executes the member information (user ID) registered in the member information database 14.
And a group of passwords) and the information (user ID and password) input from the dialog box 51, and if the corresponding user ID and password exist in the member information database 14, access to the service A menu page 52 is performed. Allow In the example of FIG. 2, the authentication using the user name and the password is described as an example. However, various other authentication methods can be considered, but the present invention is limited by the authentication method on the service A side. is not.

When the member authentication by the member authentication software 12 succeeds in the Web server 1 as described above, the service A
Is displayed on the screen of the browser software 31.

In the menu page 52 displayed on this screen, a list of available services is prepared.
In this list, link information 52 for moving to service B
When the user selects and operates the link information 52b by clicking or the like, the browser software 31 issues an access request to the menu page 61 of the service B published by the linked Web server 2. W
Issue to eb server2.

When the Web server 2 receives an access request from a user, the access method determination software 22 executes an access method determination process using information included in the access request.

That is, the access method determination software 22
As shown in FIG. 3, it is determined whether the access request from the user is for the top page of the service B (the service B menu page 61) (S101).

As a result of this determination, the top page (service B
In the case of an access request to the menu page 61 (S101)
No), the access method determination software 22 determines whether the access request is made by a link from a service page requiring member authentication (S102).

As a result of this determination, if the access request is not made by a link from a service page requiring membership authentication (No in S102), the access method determination software
The server 22 regards the access request as invalid, returns an error message to the browser software 31, and displays the message on the screen of the browser software 31 (S103).

In this case, for example, a general user who uses the Web terminal 4 knows the URL (address) of the menu page 61 of the service B for members in some form, and
Even if an access request is issued directly to the URL from 4, the service B cannot be used because the access is not by a link from the service A.

On the other hand, if the result of the determination indicates that the access request is a link from a service page requiring membership authentication (Yes in S102), the access method determination software 22 determines that the access request is from a correct route. And the browser software (member user) 31 is allowed to access the top page 61 of this service B,
The access request is notified to the HTTP server software 11.

The HTTP server software 11 creates the session information in response to the notification from the access method determination software 22 (S104), and the browser software that issues the access request
Send the top page 41 of service B to 31.

Thus, the top page 61 of the service B is displayed on the screen of the browser software 31 (S105).

When a page other than the top page 61 in the service B, such as the content page 42, is directly requested and displayed (No in S101),
The access method determination software 22 checks whether the access request is from a user having the session information (S102).

As a result of this check, if there is session information in the access request (Yes in S106), the access method determination software 22 regards the access request as being from a correct route and displays the requested page.

According to the above check, if there is no session information in the access request (No in S106), the access method determination software 22 regards the access request as invalid and returns an error message to the browser software 31.
It is displayed on the screen of the browser software 31.

As a means for preventing direct access to pages other than the top page 61 in the service B, the method using session information has been described in this example, but the session information is specifically stored. As a method, there is a method of using a cookie of browser software, a method of adding a session ID to a URL, and the like.

As described above, according to the electronic information service system of the present embodiment, only when the member user logs in to the page of the service A for performing the member authentication and accesses the service B page by following the link there, Since the Web server 2 permits access to the service B, another company (such as an ASP) that undertakes construction of a related Web site from the service provider that operates the service A receives data provision of member information from the service provider. Service B for members that only members of Service A can access without
Can be constructed.

Next, a more specific example of the electronic information service method of the present invention will be described with reference to FIG. FIG. 4 is a diagram showing an example of a screen when providing individual services to individual members.

As in this case, in service B,
In the case of providing individual information to the member from service A, it is necessary to specify the member.

Web server 2 that provides the above service B
By providing a member information database dedicated to service B, it is possible to provide a service that distinguishes members, but even in this case, it is not possible to associate with the user ID of service A.

To associate with the user ID of service A,
The member information held in the member information database 14 of the Web server 1 that provides the service A needs to be provided to the Web server 2 side. If all member information is to be notified, the present invention Not satisfied.

Therefore, when the member user moves from the service A page to the service B, a part of the information for specifying the member, such as the user ID input by the member user at the time of authentication, is added to the link information. It shall be.

In the example of FIG. 4, the user ID of the member user
If (uid) is, for example, “A123”, the service
A link 52b to service B on menu page 52 of A
For example, <A HREF = 'http: //serv_B/top.cgi
? uid = A123 '> To service B </A>.

In the Web server 2 that provides the service B, the program of the top page of the service B, for example, ht
By extracting the link information included in the access request sent from the user at tp: //serv_B/top.cgi, etc., it can be determined whether the user has moved from service A, and the link information includes uid = A123 , The user from service A can be specified.

By storing this user ID together with the session information in the service information database 23,
For example, when the member user edits a desired link by registering, for example, “usual guy” on the menu page 61 of the service B, the service B side can know what kind of preference the member user has. . It should be noted that there is a password in addition to the user ID as information for specifying the member. Here, it is assumed that only the user ID is received as the minimum information required for specifying the member, and no password is received.

As a result, the service A side sends the service B
The member information received will be the minimum necessary, and the risk of unauthorized use of the service A, which is the information providing Web site, can be reduced.

When the information added to the link information from the service A is a user ID, the Web server 2 does not investigate or judge whether or not it exists.

As described above, by asking the user ID to be described as the minimum necessary information for specifying the user in the information of the link 52b of the service A to the service B, the member user of the service A in the service B Can know the user's preference when using the service B.

Next, a specific example of recognizing that the user has moved from service A for performing member authentication to service B in the electronic information service system will be described with reference to FIG. Figure 5 shows service A to service B
FIG. 9 is a diagram showing a specific example of recognizing that the user has moved to FIG.

Service A to Service B for Member Authentication
When the Web server 2 recognizes that the user has moved to the above, the HTTP header information Referer is used.

Normally, when a user clicks a link on a Web page and a request is made by a browser to jump to the next page, the Referer holds the address of the original page to which the link was made. You.

Therefore, if a request is made to the service B from the link of the service A web page as in this case, the address of the service A web page is set in the Referer.

The access method determination software 22 of the Web server 2 reads out and determines the address held in the Referer to determine whether the user is from a formal route (route or access procedure). it can.

For example, as shown in FIG. 5, the menu page 52 of the service A is, for example, http: //serv_A/menu.html, and the link to the service B of this page is http: /
If described as /serv_B/top.cgi, when the member user accesses the service B from the link on the menu page 52 of the service A, the top.cgi is executed (S201).

This top.cgi, that is, the access method determination software 22 reads the address stored in the Referer of the HTTP header information and reads the address of the service A set in advance.
Is determined (S202). As a result of this determination, if they match (coincidence in S202), the service screen is displayed on the browser screen (S203). If they do not match (coincidence in S202), for example, "You do not have access right." An error message is displayed on the browser screen (S204).

When the user accesses the service B from the link to the service B provided on the service menu page 55 (http: //other/menu.html) or the like irrelevant to the service A, the Referer Is http: // other
/menu.html is retained, so that the judgment result by the access method judgment software 22 is
The address does not match A and an error message is displayed.

Further, when the user directly specifies http: //serv_B/top.cgi, which is the URL of the top page of the service B, using browser software such as the Web terminals 3 and 4 (S2).
05), since no information is held in Referer of the HTTP header, the determination result by the access method determination software 22 does not match the preset address of the service A, and an error message is displayed. Will be done.

As described above, when the member user uses the service A, the address of the service A is stored in the Referer of the HTTP header information, and when the user makes an access request to the Web server 2, the service is transmitted to the Referer. By determining whether the address of A is held,
It is easy to identify whether the user has moved from service A to service B.

Next, referring to FIG. 6, in this electronic information service system, when recognizing that the service has shifted from service A for performing member authentication to service B, another example in which the Referer of the HTTP header information is not used. Will be described. FIG. 6 is a diagram showing a method that does not use Referer of HTTP header information.

The setting (function) of the Referer of the HTTP header information differs depending on the type of the browser software. Even when the regular member accesses the service B via the service A, the value is not necessarily set. However, it is assumed that regular members cannot access.

Therefore, in this example, the user obtains the service A by receiving a specific keyword as additional information of the address without using Referer of the HTTP header information.
From the service B.

When a keyword is directly entered in a link as described above, additional information is known to a user with browser software capable of viewing the URL and source of a Web page. However, it is effective for a browser that cannot display the additional information. is there.

On the other hand, general browser software is Web
You can often see the URL and source of the page.

Therefore, in this example, even if the browser software for PC does not directly write a link to a page having no member information, both a site having member information (service A) and a site having no member information (service B) Prepare a web page 56 that redirects the request to the web site (using http-equiv = “refesh” etc. of the META tag) or a cgi program for checking, and exchange keywords in the back. .

In this case, as shown in FIG.
The link to service B on menu page 52 of
Describe the URL (page name) such as http: //serv_A/jump.html. The page 56 of this URL has a description instructing the browser to redirect to the check.cgi of the service B without displaying anything. Here, use the META tag http-equiv = "refesh" to redirect the request, describe the redirect destination (http: //serv_B/check.cgi) after the description of this META tag, and after that,
For example,? Keyword = 8264918 is described as a keyword.

On the other hand, check.cgi 63 is placed in service B. This check.cgi 63 checks whether or not a predetermined keyword has been added. If the predetermined keyword has been added, the top page of the service B http: // s
This is a program that instructs the browser to redirect to erv_B / top.cgi, and displays an error message on the browser if the specified keyword is not added.

In such a system configuration, when a user accesses Web server 1 (service A),
A menu page 52 is displayed on the browser screen.

When the user operates the browser to view the source description of the link to the service B on the menu page 52, the source description is http: //serv_A/jump.html. Absent.

When the user clicks on the link to the service B, the display jumps to the jump page of the service A. Here, nothing is displayed and the check.
Redirection is applied to cgi63, and for the first time, it moves to the Web server 2 side.

In the Web server 2 (service B), check.cgi 63 which is a redirect destination is executed.

The check.cgi 63 checks whether a predetermined keyword is added to the request (S30).
1) Instruct the browser to redirect to http: //serv_B/top.cgi which is the top page of service B when a predetermined keyword is added (S30)
2). If the predetermined keyword is not added, an error message is displayed on the browser (S30).
3).

[0085] The browser is redirected to http: // s
When erv_B / top.cgi is requested, the session information is checked by top.cgi (S30).
4).

As a result of this check, if the request has been given the correct session information (YES in S305)
), Service page menu page 6 of service B
1 is displayed (S306).

If the request does not include the correct session information (NO in S305), an error message is displayed on the browser screen (S307).

By configuring each site as in this example, the user writes the password in the link 52b to the service B on the menu page 52 of the service A so that the user can enter the service A
When recognizing that the user has moved to service B from, the keyword described in the link can be prevented from being easily seen by the user.

Next, a second example of a system configuration for realizing the electronic information service method according to the present invention will be described with reference to FIGS. FIG. 7 is a diagram showing a system configuration for realizing the electronic information service method according to the present invention, and FIG. 8 is a diagram showing a screen transition in this system configuration.

As shown in the figure, the electronic information service system includes a plurality of Webs connected to the Internet 5.
b. An access request is made to the servers 1 and 72 and the web servers 1 and 72, and when the access is permitted, the web server
General P that can display information published by 1,72
It comprises a computer 3 (hereinafter, referred to as PC3) as a Web terminal equipped with C browser software 31, and a portable terminal 74 having a special Web browser function different from the PC3 browser software 31. PC3 and portable terminal 74 belong to the same member user. Mobile terminal 74
Is, for example, a mobile phone.

The Web server 72 includes a service information database 23 storing information of the service B (a home page and various pages linked thereto), and an HTTP for publishing a site including the information of the service B on the Internet 5.
Server software 21, access method determination software 22 that determines whether or not the user has requested access to this site after logging in to web server 1, and only in that case, access method determination software 22 for exclusive use of service B It has a member information database 24, service B enrollment processing software 25, and service B member authentication software 26.

Service B The enrollment processing software 25
It is software that performs the process of joining the service B to the user from A and stores the user ID and password in the service B dedicated member information database 24.
The service B member authentication software 26 is software that searches the service B dedicated member information database 24 for a user who has requested access to the service B, and authenticates whether or not the user is a member. Note that the configuration of the Web server 1 is the same as that of FIG. 1, and a description thereof will be omitted.

It is extremely inconvenient for the member user that the member user needs to pass (access) the service A every time to use the service B.

If the service B is constructed to support the special browser function of the mobile terminal 74, the service provided by the mobile terminal 74 for the browser software 31 of the PC 3 The top page (screen) of A cannot be displayed, and the member user cannot use the link to go to service B via service A.

Therefore, in the system configuration of the second example, the member user performs a simple enrollment procedure for using the service B.

In this case, the member user first accesses the service A using the browser software 31 of the PC 3 and
Clicking on the “Service B subscription” ring on the menu page 52 of
The service B application screen 81 is displayed.

When the user clicks on the “Sign Up Application” link on this registration application screen 81, “Service B
Please decide the user name and password when using. A dialog box 82 displaying a message such as "" is displayed.

In this dialog box 82, the user enters "aaa" as the user ID and "123" as the password.
4 ”and the like, and performing a transmission operation, the Web server 72
Then, after the service B enrollment processing software 25 registers those data in the service B exclusive member information database 24, "The application for enrollment for service B has been completed. The service B page is at the following address." such as,
Access destination when using service B, for example, http: // s
A screen 83 showing erv_B / top.cgi and the like is displayed.

At the next time, when the member user uses the service B not from the PC 3 but from his / her own portable terminal 74, the portable terminal 74 specifies http: //serv_B/top.cgi to make an access request. .

When there is an access request, in the Web server 72, the service B member authentication software 26 displays a dialog box 84 for prompting input of a user ID and a password as a top page of the service B.

Here, the user name “aaa” and the password “1” determined during the enrollment procedure of the service B by the user.
234 ”, the service B member authentication software 26
Searches the service B exclusive member information database 24,
The entered user name “aaa” and password “123”
When data matching "4" is hit, the Web server
The access to 72 (service B) is permitted, and this is notified to the HTTP server software 21.

Thus, the service B menu page
61 is displayed and service B can be used.

In the system configuration of the second example, even if there is deleted data in the member information database 14 of the service A, it is not reflected in the member information database 24 of the service B. Only will be available.

Therefore, assuming such a case, the member information registered in the member information database 24 of the service B is provided with a valid period, and after a certain number of days has passed, the member is required to take the membership procedure again. .

As described above, if the electronic information service is performed by the system configuration of the second example, the member user of the service A can perform the simple enrollment procedure from the PC 3 or the user's own portable terminal 74 as a member. Service B can be used.

[0106] Also, the side that operates service B is
There is no need to obtain member information from A, and risks such as leakage of member information are reduced.
