Description

{Method of Servicing Information of Web Server in the Internet}

The present invention relates to a web server information service method on the Internet. In particular, the information provided from the web server is divided into static information and dynamic information, and the corresponding static information is pre-loaded on the user system. The present invention relates to a web server information service method on the Internet which performs only on-line transmission of dynamic information including authentication information.

In general, when a web server on the Internet holds data composed of a large number of pictures, videos, or documents and serves them to a large number of users, problems may arise in the speed of service. This is because there is a limitation in the performance of the server that needs to deal with a large number of servers simultaneously, and the network speed is relatively slow in transmitting large data such as pictures and videos to users.

In other words, all data to be provided to multiple users is stored on the web server, and the user can access the data on the server through a commercial web browser program such as Internet Explorer, Netscape, etc. Search, transfer and view were performed on-line.

However, if the web server manages all large amounts of data such as pictures, videos, and three-dimensional graphics in this way, there is a problem in the performance of the web server that must deal with large amounts of data simultaneously and users of large amounts of data. The speed of search and transmission can be significantly reduced because the network speed is relatively slow.

Thus, as a solution to this problem, a large number of high-performance servers are distributed and users may use a high-speed transmission system such as a cable, which requires a lot of economic cost and time in the current situation. There is this.

In addition, another solution is to store all the data in a portable storage device such as a compact disk (CD) or a digital video disk (DVD), to the user or to allow the user to receive the entire server data over the Internet. The biggest advantage is that it is not suitable for getting the latest information in real time, and there are many problems in interposing advertisement, which is the most common source of income of the web provider.

Alternatively, it is widely used for securities or bank transactions by creating and distributing a dedicated program rather than a commercial web browser to users. The dedicated programs are provided with their own information on the basic framework and most of the information is available online. The use of the dedicated program can be expected to improve some efficiency in the transmission speed by using a specialized protocol instead of HTTP, which is a web communication protocol. However, there is still a limitation in the speed of searching and transmitting in transmitting a large amount of information such as two-dimensional or three-dimensional graphics rather than text information such as stock price and transaction history.

In order to solve the problems described above, the present invention provides a user with a large or large amount of data even in a system environment where a user uses a relatively slow transmission network such as a telephone modem and a web server also has a relatively low performance. Its purpose is to make it possible to provide real-time services.

In other words, the present invention relates to a mechanism (Mechanism) to perform the transmission and viewing of a mixture of on-line and off-line on the World Wide Web (WWW), a web that provides a large amount of information The information to be serviced is divided into static information with a large and long update cycle and dynamic information with a relatively small and short update cycle, so that a differentiated service method is used for each type of information. It can be retrieved off-line, and only the dynamic information, which optionally includes authentication information, is transmitted to the user online from the web server.If the online transmission of the dynamic information is successful or the user authentication is successful, By allowing offline viewing of static information, the web server can Greatly reduces the burden that has the purpose to simultaneously enhance the detection and reading speed for a large amount of information to enable the limited information may be viewed through a transmission and authentication of information in real time.

The present invention for achieving the object as described above is the process of separating the static information and dynamic information to build a database having the same index, respectively to manage the corresponding static information database in the user system and to manage the dynamic information in the web server and ; Comparing static versions of information with each other when the user system and the web server are connected; Updating the static information database of the user system if the static information versions do not match with each other; Checking an input of a user request command, detecting an index, and requesting dynamic information using the index, and simultaneously searching for static information; And when the dynamic information is received from the web server within a predetermined time, combining the retrieved static information with the dynamic information received from the web server and outputting the combined information to the screen.

Alternatively, the present invention includes the steps of authenticating whether the user is a legitimate user when the authentication information is received from the web server within a predetermined time; In the case of the legitimate user, the method may further include combining the searched static information with the dynamic information received from the web server and outputting the combined information to the screen.

Alternatively, when all the information is built up in the database of the user system without distinguishing between the static information and the dynamic information, and authentication information is transmitted from the web server within a predetermined time at the time of connection between the user system and the web server. Authenticating whether the user is a legitimate user; In the case of the legitimate user, the method may further include combining the searched static information with the dynamic information received from the web server and outputting the combined information to the screen.

In this case, the authentication process comprises the steps of: verifying the input of the user name and password in the user system, encrypting the program together with the serial number, and transmitting the same to the web server; Receiving the encrypted value from the web server, registering it in a member database, and obtaining an encryption code and an encryption key and transmitting the encrypted code to the user system; Receiving the encryption code and the encryption key from the user system and storing them in a file; Checking an input of a user name and a password when accessing the user system and the web server, encrypting the program with a program serial number, and then confirming whether the corresponding encrypted value matches the encryption code received from the web server; And if the encrypted value matches the encryption code received from the web server, acknowledging the user as a legitimate user. Alternatively, the authentication process is characterized in that it further comprises a step of changing the encryption code and the encryption key from time to time whenever the connection between the user system and the web server, and managing the changed encryption key in the web server. .

The present invention divides the data to be provided into static information and dynamic information. The static information is a long change period that is hardly changed once created. For example, it may be a large picture or video data. It is transmitted to a user in a portable storage medium such as a mobile device or loaded on a user system through a batch transmission using the Internet. The dynamic information is short information that is changed periodically. It is mounted on a web server system and provided when a user connects via the Internet.

In addition, the present invention does not allow the user to view the static information offline, but must be connected online with the dynamic information while connected to the server system, that is, the user has the static information in his or her system, To access it, you must receive dynamic information after authenticating from the server system. As such, since the dynamic information is small in size, only the dynamic information having the small size is transmitted, thereby reducing the burden on the server and the network as compared with simultaneously transmitting the dynamic and static information. On the other hand, it is necessary to read static information from the user's system into a web browser program such as Internet Explorer or Netscape, but it is very small compared to the transmission time of the whole information or the burden on the server, and also without using a general web browser. Performance can be further improved by using specialized programs.

In addition, in the present invention, since the static information is loaded in advance on the user side and only small dynamic information is transmitted, it is possible to perform very fast information retrieval and reading even in a relatively low-speed communication network, and in the server side, the dynamic size is small. Since only information needs to be processed and transmitted, the burden on processing and transmission can be reduced. In addition, since the static information has a large change cycle, version management may be performed and transmitted at regular intervals or may be periodically mailed to a new version. In particular, in the case of commercial multimedia information such as movies and music, authentication is required every time users play after free distribution, and commercial effects can be expected by using dynamic information such as advertisements in the process. To implement it. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As illustrated in FIG. 1, a configuration for a web server information service in the Internet according to an embodiment of the present invention includes a user system 10 and a web server system 20. Among them, a large update period or a large amount of information is classified into static information and built in the corresponding user system 10, and a small update period or small amount of information is classified into dynamic information and built into the corresponding web server system 20 to build the corresponding user. The system 10 and the web server system 20 may be configured to perform information transmission and viewing.

The user system 10 includes a static information database 11 for storing static information received through a mobile storage medium or over the Internet, and a plug-in program or a Java applet program therein. A web browser 12 which requests and receives static information or dynamic information from the web server system 20 and combines the corresponding static information and dynamic information to display to the user. It is made to include. Here, the user can access the web server system 20 through a web browser 12 such as Internet Explorer, Netscape, etc. without having to run a specialized program, and the plug-in program 12-in the web browser 12 can be accessed. 1) is a program provided by the web server system 20, and the corresponding Java applet program 12-1 is an authentication program.

The web server system 20 restricts access to the system using a dynamic information database 21 storing the dynamic information and information at the time of user identification or static information initialization. Or authentication server 22 to allow access only to the user.

The web server information service method in the Internet according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 2 as follows.

First, information to be provided to a plurality of users in the web server system 20 is divided into static information having a large and long update period and dynamic information having a small and short update period, and the corresponding web server system 20 Since the information provided in the) is built into the database, the static and dynamic information can be built into an independent database having the same index (step S1).

That is, the static information is stored in the static information database 11 in the user system 10 and the dynamic information is stored in the dynamic information database 21 in the web server system and the static information and the dynamic information are stored in the same index. Mapping, that is, the static information database 11 and the dynamic information database 21 to share a single index. This is because when a user requests a single index, the static information in the user system 10 and the dynamic information in the web server system 20 can be simultaneously called through the requested single index. .

At this time, the static information is stored in a portable storage medium such as CD, DVD, etc. to be distributed to the user to be installed in advance in the user system 10 or received collectively from the web server system 20 via the Internet The static information database 11 is constructed by being installed in the user system 10 in advance. In addition, a user cannot directly access the static information database 11 and use the static information.

Then, when the user executes the web browser 12 to search for some information or browse some information on the web browser 12 in the user system 10, the internal plug-in program 12-1 Or it drives the Java applet program 12-1 authenticated to access the resources of the user system 10 (step S2).

Therefore, as soon as the plug-in program or the Java applet program 12-1 is started, it is checked whether the static information of the user is up to date through the static information version check with the web server system 20, that is, the web server system ( The static information version of 20) is checked and compared with the version of the static information stored in the static information database 11 (step S3).

If the version of the static information stored in the static information database 11 does not match the static information version of the web server system 20 in the third step S3, the static information database 11 is stored in the static information database 11. Up-dating the stored static information (step S4). In this case, when there is little static information to be updated, the web server system 20 directly receives the information online and when there is a lot of static information to be updated or when the user's network condition is not good, a mobile storage medium is used. It is recommended to update the static information stored in the static information database 11 to the same as the static information version of the web server system 20 by being authorized through the corresponding mobile storage medium.

Then, when the user inputs a search command for searching for some information or a browse command for reading some information on the web browser 12 in the user system 10, the plug-in program or the Java applet program 12- 1) waits for the user's input and checks the input of the search command or the browsing command (step S5) to check the index in the command requested by the user (step S6).

The dynamic index corresponding to the identified index is requested to the web server system 20 through the Internet using the identified index, and corresponds to the static information database 11 in the user system 10. The static information corresponding to the checked index is retrieved (step S7).

Accordingly, the web server system 20 receives the dynamic information request from the user system 10 and retrieves the dynamic information stored in the internal dynamic information database 21 and transmits the dynamic information to the user system 10. . In this case, in order to confirm whether the user system 10 or the user is correct, the user system 10 may optionally transmit the authentication information.

Accordingly, when no authentication is required for the user, the plug-in program or Java applet program 12-1 checks whether dynamic information has been received from the web server system 20 within a predetermined time (step S8). ).

If the reception of the dynamic information is abnormal in the eighth step (S8), that is, even if the search for the static information is completed, the dynamic information cannot be received from the web server system 20 due to a network or system problem. In this case, the plug-in program or the Java applet program 12-1 causes the error screen to be output without outputting the retrieved static information on the screen (step S9). In addition, this case also includes a case of attempting to access the static information in the offline state.

On the other hand, when the dynamic information is normally received from the web server system 20 in the eighth step S8, the static information retrieved from the static information database 11 and the web server system 20 are received. The dynamic information is combined and output on the screen at the same time (step S10).

Alternatively, if authentication is required for the user, the plug-in program or Java applet program 12-1 checks whether the authentication information has been received together with the dynamic information from the web server system 20 within a predetermined time. (Step S11).

If the dynamic information and the authentication information are not received from the web server system 20 in the eleventh step S11, an error screen is output in the same manner as in the ninth step S9 (S9). Step S12).

On the other hand, when the dynamic information and the authentication information are normally received from the web server system 20 in the eleventh step S11, the plug-in program or the Java applet program 12-1 receives the web server system 20. (B) verifying whether the user is the correct user by authenticating the authentication information transmitted from the user side, i.e., checking the user information and the system information through the authentication server 22 of the web server system 20. (Step S13).

At this time, when an error occurs in the authentication information in the thirteenth step (S13), that is, not the correct user, the error screen is output in the same manner as in the ninth step (S9) (step S14).

However, if the user is the correct user in the thirteenth step S13, the static information retrieved from the static information database 11 and the dynamic information received from the web server system 20 are combined and output on the screen at the same time (step S15).

As described above, the authentication information can be selectively used and is not used when there is no limitation of the user. The static information can be updated through static version management, and when the user accesses the web, the user system 10 checks the static version of the information and transfers the static information as much as the difference between the versions or stores the updated static information. You can update via media.

In addition, as another example, all information may be distributed without distinguishing between static information and dynamic information, built in a database in the user system 10, and may be used with limited authentication in using the information. Allows access to information based on whether or not it is transmitted.

Then, in brief description of the procedure for authenticating whether the user is the correct user in the thirteenth step (S13), the user system 10 first authenticates the user through a user name and a password, and then the corresponding user through the web server system 20. According to whether the encryption key of the user system 10 and the encryption key registered in the web server system 20 match, it is possible to determine whether the program is an illegal copy or a legitimate program, and also the continuous reliability of the system. For maintenance purposes, the encryption key of each user program is changed frequently each time the user connects. Hereinafter, the authentication procedure will be described in more detail with reference to the flowchart of FIG. 3.

First, a process of initial registration is performed, and when each user inputs a user name and password, the user system 10 confirms the input of the user name and password (step S13-1). After encrypting the input user name and password together with the serial number (step S13-2), the encrypted value is transmitted to the web server system 20 (step S13-3).

Accordingly, the web server system 20 receives the encrypted user name, password, and program serial number from the user system 10 (step S13-4), and then first registers it in the member database therein (step S13-). 5), an encryption code (e.g. MD5) and an encryption key of a string combining the corresponding user name, password and program serial number are obtained and transmitted to the user system 10 (step S13-6).

Accordingly, the user system 10 receives the encryption code and the encryption key from the web server system 20 (step S13-7) and stores the file as a file in its own system (step S13). -8).

Then, when the user accesses the web server system 20 using a program, the user system 10 receives a user name and password from the user (step S13-9) and the web server together with the program serial number. As in the system 20, encryption is performed using an encryption key (step S13-10), and it is checked whether the encrypted value matches the encryption code received from the web server system 20 (step S13-11).

If it does not match in step 13-11 (S13-11), an error screen is output to inform the user that an incorrect user name or password is input (step S13-12), and the step 13-11 ( If it matches in S13-11), it is recognized as a legitimate user (steps S13-13).

In addition, every time a user accesses the web server system 20 through a user program, the user changes the encryption code and the encryption key from time to time and manages the changed encryption key in the web server system 20, thereby preventing illegal copying. Prevent damages in advance.

On the other hand, the above-described method can be applied to a geographic area information web server. The geographic area information web server contains two-dimensional or three-dimensional maps from various viewpoints and useful information of the area. In such a system, two-dimensional or three-dimensional map information is very large and requires a great amount of time and resources to transmit. Therefore, the information is classified as static information according to an embodiment of the present invention. Long periods of time and large amounts of information can be classified as static information. For example, there may be a name of a road, a name of a building, a name of a business renting a building, and a floor plan of a building.

The remaining information, that is, a short change cycle and small amount of information, is classified into dynamic information. In particular, in the case of a commercial web server, a coupon or an advertisement banner issued by a business may be included in the dynamic information.

Then, when the user inputs a command such as a map movement, detailing, request for specific building information, and requesting additional information on the web page using the present invention, the index corresponding to the command is detected, and the static information having the corresponding index and The dynamic information is read at the same time and displayed on the user screen.

Accordingly, a user can search and view a large amount of maps and local information at high speed, and a web server provider can transmit data such as data desired by the user and advertisements to be provided to the user at high speed.

In addition, it is also very useful for transmitting image data such as pictures and photos, sound data such as voice and music, and multimedia data such as movies and music videos using the web. If you browse through the user can be guaranteed the satisfactory performance by viewing the information in their system, the data provider can be a profitable business, including advertising, cyber money and the like through the web. In addition, since the authentication process must always be performed at the time of reading, illegal copying can be prevented.

In addition, in the case of dictionaries such as encyclopedias and English-Korean dictionaries, the amount of multimedia data is not large, but the amount of the entire data is large and high-speed search is required.

As described above, according to the present invention, the information managed by the web server is divided into static information and dynamic information, separated and managed by the web server and the user system, and the access of the static information is restricted and distributed through the mobile storage medium without the transmission of the dynamic information. In order to view data distributed through the Internet or to be authenticated by a web server, it is possible to view data, which is relatively slow when performing information transmission, retrieval and viewing between a web server having a large amount of data and a user web browser. Even in a speed network environment, users can get the information they want at high speed, and they can reduce the computational burden of the server itself while sending out real-time information from the web server at high speed.
