Description

Method of controlling the remote data on the internet}

The present invention relates to remote data control on the Internet. More specifically, the subscriber can handle data as if the user is working on local storage, such as storing, moving, copying, and deleting necessary data regardless of access location and environment. It relates to a remote data control method that can be.

In general, the Internet consists of a number of computers and computer networks connected through communication links. Interconnected computers can exchange information using a variety of services, such as e-mail, gopher, FTP, and the World Wide Web. A web (WWW) service is a server computer system (ie, a web server). Web page information written in HTML is transmitted to a remote client system. Each resource on the web (that is, a computer or web page) is given a unique uniform resource locator (URL), and in order to view a particular web page, the client system designates the URL of that web page and transmits it according to the HTTP protocol. If so, the server system sends corresponding web page information correspondingly. When the client system receives the web page, the client system typically displays it on the monitor through a browser.

However, the conventional simple file transfer using FTP and HTTP on the Internet does not read and write in real time, which may cause synchronization of file contents. In addition, since data is transmitted and received in a certain upload and download format of the Internet, data handling is cumbersome because the method is different from the user's local environment when the data is moved and replicated.

The present invention is to provide a remote data control method on the Internet that can efficiently manage the remote data in order to solve the above problems.

In order to achieve the above object, the method of the present invention provides a web storage service by a web storage service site on the Internet, wherein the authentication is performed after inputting an ID and password to the web storage service site through a web browser. Doing; If the authentication result is a normal subscriber, delivering a cookie and accessing a web storage server; And controlling a data through the Internet by selecting a desired function according to the service menu.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the overall network configuration to which the present invention is applied. Referring to FIG. 1, a plurality of users are connected to the Internet 110 through computers 102 and 104, and a site 120 providing a web storage service according to the present invention is connected to the Internet through a switching hub 121. Provides a web storage service that allows users to store, copy, delete, and change data on the web, including a web server 122, an image server 123, and storage servers 124-1 to 124-n. .

The web server 122 is responsible for service subscriber management and overall management as a main server, and the image server 123 stores images that are delivered to users for load balancing. The n storage servers 124-1 through 124-n are servers in which web storage navigation, CGI, and user home directories are actually stored.

As such, the present invention provides a user-friendly environment by defining a format of a service logic program, accessing data storage on the Internet using a network drive, and file metaphor. To this end, the present invention is implemented by a method using HTTP, which is a WWW standard transport protocol (first embodiment), and a method using "SAMBA" made based on the SMB (Server Message Block) protocol (second embodiment).

First embodiment

2 is a conceptual diagram illustrating a procedure for controlling remote data using the HTTP method according to the present invention, and FIG. 3 is a flowchart illustrating a procedure for controlling remote data using the HTTP method according to the present invention.

The method for implementing a web storage service using HTTP according to the present invention implements a basic function (directory creation, file copy, move, delete, etc.) that handles files on the web by using a CGI program. It is to perform web storage service using.

2, a user (Client) accesses a master web server (Master WWW Server) of a web storage service site providing a service according to the present invention on a browser, and logs in by inputting an ID and a password (①). The master web server compares the username and password input from the user to the user database and authenticates them, and delivers the authentication result to the user. If the authentication result is a normal user, ID and Cookie (Cookie ID, WH) of web storage are provided (②). The user then accesses the web server (WH1 WWW SERVER) of the storage server (③). At this time, the storage web server (WH1 WWW SERVER) provides a menu for the web storage service, and connects to the web storage FTP server (WH2 ~ WH (n) FTP SERVER) according to the user's choice. Provide practical services such as modifications (④).

Referring to FIG. 3, a user accesses a web server after driving a web browser (301). If you are a member, enter your ID (ID) and password, and if you are not a member, you are given an ID and password through the membership registration procedure (302 ~ 305). Subsequently, the web server authenticates the subscriber using the ID and password input by the user, and if the subscriber is a normal subscriber, provides the cookie related to the web storage service assigned to the subscriber (306, 307). After accessing the web server of the web storage server and displaying the service menu, the user selects a desired function from the service menu item and provides services such as creating a new directory, transferring a file, copying, changing, deleting, and sharing ( 308,309).

If a user selects a new directory service, a directory is created. If a user selects file transfer (upload / download), the user uploads or downloads a designated file (310 to 313). If you select Copy File, the specified file is copied. If you select Change, the specified file is changed. If you select Delete, the specified file is deleted (314 ~ 319). If the share is selected, the attribute of the file is changed to be accessible to other users (320 and 321).

As described above, according to the first exemplary embodiment, data can be easily controlled on the web by providing a web storage service in a menu method on a web browser.

Second embodiment

4 is a conceptual diagram illustrating a procedure for controlling remote data using the SAMBA method according to the present invention, and FIG. 5 is a flowchart illustrating a procedure for controlling remote data using the SAMBA method according to the present invention. For the service according to the second embodiment, the subscriber downloads a predetermined program from the web storage site at the time of membership registration and creates a network drive.

In the second embodiment, after receiving the ID and password through the subscriber authentication daemon using the SAMBA made based on SMB, the subscriber receives the information of the assigned server. Information on the subscriber computer that can find the server by its NetBIOS name is recorded in the "Imhosts" file, connected to the server and logged on to the service. Here, SMB stands for Server Message Block and is the core protocol of SAMBA, which has been in progress since 1987 at Wintel. SMB is already in the process of being standardized by the IETF under the name CIFS and has a typical client / server, request / response protocol structure and can share not only filesystems but also resources such as printers, serial ports, named pipes and mailslots. Make sure Because of this characteristic of SMB, the method using SAMBA can be applied to other applications besides file system sharing. Another feature of SMB is that it can operate over heterogeneous network protocols. In other words, SMB can run smoothly over multiple different networks, such as TCP / IP, NetBEUI, IPX / SPX. In order for SMB to operate on top of the TCP / IP or NetBEUI protocol, you must use the Netbios name service.

SAMBA is server software that simulates the SMB protocol running on UNIX machines with standard TCP / IP. Therefore, clients supporting SMB can easily access various resources such as file system and printer on the server side running SAMBA. Compared to other network file sharing software, SAMBA is now available free of charge under source code under the GNU General Public License (GPL).

This method of using SAMBA supports connecting the web server storage to the explorer for users who are familiar with the Windows Explorer environment. The server side adds an authentication module for subscriber authentication and a "quota" module for usage checking using the basic SAMBA. After ID / Password is authenticated through the server-side authentication daemon, the subscriber receives the information of the assigned server, and the information to find the server by Netbios name on the subscriber PC is recorded in the Imhosts file and connected to the server.

Referring to FIG. 4, when a user runs a web storage skin on a network drive of a user PC and inputs an ID and a password, subscriber authentication is performed to a database through a switching daemon (①).

If the authentication result is a normal subscriber, the web storage related information is provided to the user (②), and the client running on the user PC requests the FTP connection to the SAMBA server by referring to it (③). The SAMBA server then authenticates the user database again with the normal subscriber and processes the connection with the user (④).

Referring to FIG. 5, when the web storage client is run on a user PC after installing the web storage, a connection skin screen as shown in FIG. 4 appears, and the user inputs an ID and a password (501 and 502). After accessing the site, the authentication process is performed. If the subscriber is a normal subscriber, the user accesses the SAMBA server (503, 504).

As described above, when the web storage is used while connected to the SAMBA server, it is used in the same manner as the network drive in the Windows Explorer (505). In other words, the web storage is displayed as a network drive in Windows Explorer after connecting. If you drag and drop a file to be stored in the web storage, the file is transferred and stored on the web storage. When implementing web storage using SAMBA method, web storage can be used similarly to network drive.

As described above, the present invention can implement the same function as the hard disk of the local computer on the web using the HTTP protocol or SAMBA to manage the remote data in the environment familiar with their PC, the storage space on the Internet Provides a safer and more convenient way to back up your data. In particular, the user who moves frequently can have their own data storage means that can be accessed anytime, anywhere, and is convenient to use, and unlike a storage means in a notebook computer, there is no fear of losing.
