KR20030092459A - Auto Login System - Google Patents

Abstract

PURPOSE: An automatic login system is provided to offer more convenient and stable method to a user, and to give a site provider an opportunity to let more users know a site. CONSTITUTION: If the user logs in to the site of the site provider, a main server program(2100) of the site provider generates sub servers(2110,2120) for respective clients(3110,3120). The sub server uses a thread for an executing capability. The sub server stores the information for a new site transferred from a client(3110) in a database while keeping the connection with the client. A client program receives an execution command from the main server program. The client program residing in a user computer performs login if the information is existed in a cache when the user connects to a constant site. The client program is terminated if the connection with the site provider is cut off. If the client program is terminated, the sub server allotted to the client is terminated too. The client program is terminated after deleting a recording cache used by the user.

Description

Auto Login System {Auto Login System}

The present invention relates to a user's convenience in using the Internet, and more particularly, to a login.

In the case of the existing site, the user had to log in to the subscribed site and use the user authentication. However, more and more sites are joined by users. As a result, users want to use the same username and password, but they must use a different username and password if they already have the same username. When this happens a lot, users can forget their usernames and passwords or be confused. The system aims to solve this problem.

There are three examples of the prior art.

Firstly, it is a method of inputting ID and password for each site to authenticate individually. This is the oldest method and causes users to forget their username and password.

Secondly, all of them are managed by the site provider's server.

1 is a diagram for explaining this. As shown,

The client 300 connects to the web server 200 of the site provider and subscribes. The contents recorded at the time of subscription are recorded in the database 100 of the site provider. After that, when the user logs in to the site provider's web server, the list of currently registered sites is displayed. You can add, modify, and delete sites. When the user requests access to the registered site, the site provider processes the login and displays the page after the login.

In order to implement this method, the database of the site provider should store the user's details, registered sites, and registered names. In addition, the site provider's database must store the URL of each site's login page.

This method has the advantage of informing the site provider because the user should always access the site provider's site, and has the advantage that it can be used anywhere in the home, PC room, etc. However, if a particular site is not recorded in the site provider's database, the user is unavailable and a large number of users place a lot of load on the site provider's server.

Third, all of them are managed by the client. (Figure 2)

This method is used by a user downloading a program from a program provider. The program stores the information of the site each user wants to go to on the user's computer.

When a user logs in to a particular site, the program looks up the user's information. If there is information, the information is used. If not, the user is asked whether to add it.

This method analyzes HTML code when a user connects to a new site and retrieves the contents of the <FORM> </ FORM> tag. If there is a TextBox whose attribute is a password ("password"), the space will be recognized as the password. In addition, since the ID is normally written on the password, it is recognized as the ID. After the recognition, the information is stored on the user's computer. Because it is stored in the user's computer, it is encrypted so that it cannot be easily fixed. If the user wants to use the stored information, the information is used, and the user is also asked when adding new information.

The advantage of this approach is that there is very little load on the server. Since all the processing is done on the user's computer, the provider's server only needs to transfer it on the first download. It can also be used to log in from any page. However, this method does not greatly inform the user of the provider, and it is difficult to use it because of security problems when several people use the same computer, such as a game room.

In order to solve the above problems of the present invention, an object of the present invention is to provide a user with a more convenient and stable method, and to provide a system for giving a site provider an opportunity to inform themselves more.

The present invention is basically provided through the web and is provided by combining the advantages of the processing method in the server side and the client side. This includes a database server, a web server, a main program server, one or more sub program servers, and one or more client connections.

The Main Program Server is always running with the web server.

Sub Program Server ensures connection with clients.

When you need to use cookies, you should always delete the contents of the client program to protect your privacy. Since information in the database must be protected, information requests and changes are made through the Server Program without receiving information requests directly from client programs.

An Auto Login System according to the invention is shown in FIG. 3.

As shown, a database 1000 for storing user data and a Server 2000 serving as a bridge between the database and the user are configured. In addition, the user has a client program (3100).

Although not shown, the server 1000 is divided into a web server, a main program server, and a sub program server. There is a separate cache in the client program.

The database server communicates with the web server and the sub program server. This allows users to manage their information more securely by not connecting directly to the database server. The web server searches the database according to the user's authentication request, and the database server sends the results to the web server.

If the user is successfully authenticated at the site provider's site, the Main Program Server uses the information to run the client program on the user's computer and run the Sub Program Server.

The Sub Program Server maintains connection with the client program, searches the database 1000 for user information received from the client, and adds, modifies, and deletes the data.

The client program has a separate cache so that it can handle itself as far as possible without having to call the server each time.

When a user joins a site provider's site, the user's information is stored in the site provider's database. Information in the database (Fig. 4) is divided into three.

First, the user table (Fig. 4-Table I) has the personal details of the users who have joined the site provider's site and the ID and password for logging in to the site provider's site. User's personal information can be modified and deleted through web page.

Secondly, the site table (Fig. 4-Table II) stores the URL of each site requiring login and the name of the site.

Third, there is a USER_SITE table (Fig. 4-Table III) that stores which sites each user has an ID and password. The reason for separating this table from the site table is to eliminate duplication of information.

After the user joins the site and stores the information in a database, the user is asked to install the client program. This program is executed when the user logs in to the site provider's web site and terminates when the user logs out. The program consists of a list of sites registered by the user and a menu to manage (add, modify, delete). The user can select a list existing in the program and move to the logged in state of the page. If the user wants to connect to a specific site by launching a browser separately, the user first searches through the server (Fig. 5) to see if it already has the information. Otherwise, the site is stored in a database (Fig. 4-Table II). If you click the record button in the client program, the contents after that are recorded and the contents are stored in the database (Fig. 4-Table III). The client program then caches the information for itself. Sites that the user has already accessed are handled using the contents of the cache. When the program exits, the cache contents are cleared for security. To show the logged in page to the user, use POSTDATA during user logging.

When the user logs in to the site provider's site, the site provider's Main Server Program 2100 creates secondary servers 2110 and 2120 for each client 3110 and 3120. The secondary server uses threads for performance. The main server program 2100 only executes the clients 3110 and 3120 and generates the auxiliary servers 2110 and 2120. After that, the secondary server 2110 maintains a connection with the client 3110 and stores information of a new site transmitted from the client in the database 1000 (FIG. 7).

The client program (FIG. 8) receives execution instructions from the Main Server Program as described above. After that, if the user resides on the user's computer and is searching for information in his or her cache when the user connects to a particular site, the user logs in. If not, get the information from the server and search for the information you already have, and if so, log in. If not, the information is transmitted to the secondary server 2110, and the information is also stored in its own cache. The client program terminates when the connection with the site provider is lost. When the client program terminates, the secondary server allocated for the client is also terminated, and the client program terminates after deleting the recording cache used by the user.

As described above, according to the present invention, the user can conveniently use it at any place such as a home, a PC room, or an Internet cafe. The present invention can solve most of the problems caused by serious security problems or server performance problems on the provider side.

And users don't have to worry about ID and password any more because they only need to remember one ID for the site provider's page.

In addition, site providers can always inform themselves through their own programs to users who use more convenient services, so that they can benefit from advertising.
