Description

System and Method for Sharing Information

The present invention relates to an information sharing system and method, and more particularly, to implement a navigator function using a web browser in an Internet environment, and based on the same, a plurality of terminals that the user wants to share information of a user terminal desired by the user. The present invention relates to information sharing technology that can safely and efficiently share information.

In general, an information sharing system is a system capable of sharing information among a plurality of terminals. For example, the information sharing system may refer to a system that can share information such as software or content by providing information or receiving information through an indirect or direct route from one terminal to another terminal.

Typically, such information sharing systems may be based on client-server systems. The client-server system consists of a server and a plurality of client terminals. The server may include an information sharing space for uploading or downloading information, for example, a bulletin board or a web hard. Each client terminal may upload information to an information sharing space provided in the server, or may download information uploaded to the information sharing space by another client terminal.

The information sharing system based on such a client-server system has a server-dominated configuration that operates in a server-centric manner. However, such a client-server system-based information sharing system has an excessive load on the server side as the amount of information increases or the number of client terminals increases, and services are provided according to information storage capacity, data processing capability, and communication capability of the server. There is a drawback that the quality is clearly dependent. In addition, from the user's point of view, since the information must be uploaded and downloaded to the server one by one, there are also inconvenient problems.

Therefore, the information sharing system based on peer-to-peer (P2P: P2P) has been developed as a substitute for such a client-server system-based information sharing system. The P2P based information sharing system may be composed of a plurality of peer terminals interconnected through a communication network and capable of storing information, respectively. Such a P2P based information sharing system directly transmits information between peer terminals, thereby enabling rapid sharing of information.

However, such a P2P-based information sharing system includes a problem that information is indiscriminately shared because a plurality of peer terminals are connected in a mesh form and each peer terminal connected to the communication network becomes both a provider of information and a consumer of information. have. In particular, P2P-based information sharing system is a reality that is recognized as illegal technology for users due to the problem of copyrighted information sharing, security vulnerability. In addition, the P2P-based information sharing system has a problem that each peer terminal is inconvenient to all Internet users due to excessive network load due to broadcasting information to an unspecified number of peer terminals.

Accordingly, there is an urgent need to develop a new type of information sharing system capable of solving the problems of the conventional information sharing systems and enabling a system configuration that is legal, convenient to use, and efficient.

Each node refers to a device or a functional unit that operates at an equal status in the same protocol layer of a communication network using a hierarchical protocol in data communication, and may be referred to as a peer, for example. The node may be a network device such as a personal computer (PC) or the like.

Nodes included in the P2P network can directly share information such as a file with each other. In a P2P system, a node may broadcast information to other nodes. In other words, P2P systems can share information in many-to-many communications. That is, in a P2P system, each node can be both a service provider and a service consumer.

In this P2P system, information stored in terminals connected to the network is indiscriminately shared among other terminals connected to the P2P, so there is a high possibility of unintentional leakage of information, and thus, weak security and illegal sharing of copyrighted content. Can be.

As shown in FIG. 2, the information sharing system 1 according to the preferred embodiment of the present invention may include at least one user sharing group M1, M2, M3. Here, the user sharing group may mean a group of client terminals that can share and use a selected information area included in a specific client terminal included in the user sharing group, for example, a shared folder. For example, the information sharing system 1 may include a first user sharing group M1, a second user sharing group M2, a third user sharing group M3, and the like.

The first user sharing group M1 may include a plurality of client terminals, for example, a first client terminal C1, a second client terminal C2, and a third client terminal C3. The client terminals C1, C2, and C3 of the first user sharing group M1 may share and use the shared folder of the first client terminal C1, for example.

Client terminals C1, C2, and C3 of the first user sharing group M1 may perform peer-to-peer communication, that is, peer-to-peer communication, for use of the shared folder. Therefore, each client terminal C1, C2, C3 may mean a peer in P2P communication. Each client terminal C1, C2, C3, on the other hand, has a service server unit for user registration, login, transmission of shared folder setting information and shared user identification information, reception of shared folder setting information and shared user identification information, and the like. (SV) and client-server communication. Thus, each client terminal C1, C2, C3 is a peer in P2P and on the other hand a client.

In the same concept as the description of the first user sharing group M1, the second user sharing group M2 includes a plurality of client terminals, for example, a second client terminal C2, a fourth client terminal C4, and a sixth group. It may include a client terminal C6. The client terminals C1, C2, and C3 of the second user sharing group M2 may share and use a shared folder of the fourth client terminal C4, for example. In addition, the third user sharing group M3 may include a plurality of client terminals, for example, a third client terminal C3, a fifth client terminal C5, and a sixth client terminal C6. The client terminals C1, C2, C3 of the third user sharing group M3 may share and use the shared folder of the fifth client terminal C5, for example.

In the information sharing system according to the present invention, the number of user sharing groups and the number of client terminals included in each user sharing group may be variously configured according to an implementation environment. Hereinafter, the configuration and function of the information sharing system will be described in detail.

In the following description, for convenience of understanding, the first client terminal C1, the second client terminal C2, and the third client terminal C3 and the service server unit of the first user sharing group M1 shown in FIG. 2 are illustrated. As an information sharing system including an SV, an example in which the shared folder of the first client terminal C1 is shared with the second client terminal C2 and the third client terminal C3 will be described.

The first client terminal C1 and the third client terminal C3 may log in to the service server unit SV as user identification information of the first user. Similarly, the second user may register himself or herself as a user in the service server unit SV through the second client terminal C2, and after the user registration, the second client terminal C2 is used as user identification information of the second user. It is possible to log in to the service server unit SV.

The sharing control unit 13 may transmit a search tree display request to the client terminals C1, C2, and C3 and process and manage information for sharing a folder among the client terminals C1, C2, and C3. . The search tree display request may be a message requesting to display the search tree in the web browser of the client terminals C1, C2, and C3.

The sharing control unit 13 receives the shared folder setting information and the shared user identification information from any one of the logged-in client terminals (for example, C1), associates the shared folder setting information and the shared user identification information with each other in the database unit 20. Can be stored in the shared information database 24. The shared folder setting information may refer to information for setting a shared folder to be shared, and the shared user identification information may refer to user identification information for sharing the shared folder.

For example, the first user wants to share a certain folder of the first client terminal C1 with client terminals of the first user and the second user, that is, the third client terminal C3 and the second client terminal C2. Assume that the sharing control unit 13 includes shared folder setting information including information for setting the folder of the first client terminal C1 as a shared folder from the first client terminal C1 and the first user and the second. Shared user identification information indicating that the user is set as a shared user can be received, and the received information can be associated and stored in the shared information database 24.
