FILE SEARCHING METHOD FOR PEER TO PEER AND SHARING METHOD THE SAME}

The present invention relates to a peer-to-peer file search and share method, and more particularly, to a peer-to-peer file search and share method for evaluating and exchanging a file's value.

P2P, which has been discussed a lot in the internet business recently, is an abbreviation of peer-to-peer (hereinafter referred to as peer-to-peer) and is an implicit term for expressing important changes in the internet business. Peer-to-peer file sharing systems can receive, retrieve, and download information directly from any node connected to the Internet, that is, from a personal computer, unlike traditional methods of finding information on the Internet through search engines. This can extend the information extraction paths that were limited to websites to databases operated by individuals or companies. That is, it manages and manages its own information nationwide or globally, and it is possible to form a community among users who want to share the same information as well as share various information among users.

The peer-to-peer file sharing system uses a method of sharing files by paying packets for a fee. In addition, since the existing peer-to-peer file sharing system simply searches by file name, there is a problem that the file name cannot be searched if the file name is unexpected to the user.

In addition, in the case of a file sharing method for free, users tend to be reluctant to share files because sharing their files reduces bandwidth and slows down. Therefore, the user wants to obtain a desired file without sharing his file, and in the case of a file sharing method in which information can be exchanged when a shared file exists, it is difficult to smoothly share a file by designating a file that is not useful as a shared file. In addition, in the case of a file that is generally shared instead of the first share, a user may maliciously deceive the file name, so even if the file name and the file content are different, there is no way to check the file until the file is downloaded. Therefore, there is a problem that the reliability and accuracy of the search results are lowered.

It is an object of the present invention to provide a peer-to-peer file search and sharing method that facilitates the exchange of information.

Another object of the present invention is to provide a peer-to-peer file search and sharing method that can improve the reliability of a shared file.

In order to achieve the above object, the present invention provides a peer-to-peer system for sharing a file using a super node between a user and another user, the step of notifying the super node of the shared file of the one user, Notifying the super node of the file requested by the user, the super node notifying the one user of another user who has the file requested by the one user, and requesting the other user of the file requested by the one user Peer-to-peer, comprising: evaluating the shared file of the one user by the other user; and sharing or not sharing the file requested by the one user according to the evaluation result of the shared file. Provides a way to search and share peer files.

The notifying the super node of the file requested by the one user includes automatically searching according to the selection of the one user, and the searching automatically comprises a genre of the file requested by the one user. Selecting and searching in the super node of the genre field.

Evaluating the shared file of the one user by the other user includes comparing the value of the shared file of the one user with a file requested by the one user. In the step of the other user sharing or not sharing the file requested by the one user, the other user shares the file requested by the one user according to a result of comparing the value of the shared file of the one user and the file requested by the one user. You may or may not share it.

The evaluating the other user by the one user may include evaluating the other user according to the accuracy of a file shared by the other user, and notifying the super node of the evaluation of the other user to evaluate the other user. Sharing.

Also, when the other user shares the file requested by the one user in the step of sharing or not sharing the file requested by the one user according to the evaluation result of the shared file, the one user evaluates the other user. It includes more.

According to the present invention, a peer-to-peer file search and sharing that can actively exchange information by checking the contents of a file in advance by using a tag of a file and evaluating the value of the file and exchanging a file-to-file by all users based on this. Provide a method.

The present invention also provides a peer-to-peer file search and sharing method that can block a fake file and a user who intentionally shares the fake file by downloading the file and evaluating the file and the user.

In addition, the present invention provides a peer-to-peer file search and sharing method that can intentionally block a fake file and a fake file to increase search accuracy.
In addition, the present invention can provide a peer-to-peer file searching and sharing method that can easily download a file by obtaining a search result close to the file to be downloaded with information such as the genre of the file even if the file name is not known. .

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

It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Like reference numerals in the drawings refer to like elements.

1 is a conceptual diagram of a peer to peer network according to the present invention.

As shown in FIG. 1, a peer-to-peer network according to the present invention includes a server, a super node SN ₁ and SN ₂ connected to the server, and nodes N ₁ to N connected to the super nodes SN ₁ and SN ₂ . N ₂ ). In addition, a plurality of super nodes SN ₁ and SN ₂ and nodes N ₁ to N ₂ are connected to a server by being connected in a network structure.

The server is a computer system for providing main information or performing a task, and returns a result of performing a task or information requested by the client system to the client system.

A super node is a node that satisfies a specific condition among a plurality of nodes, for example, a computer whose performance and internet line speed satisfy a certain condition. In the present embodiment, two super nodes, namely, A first super node SN ₁ and a second super node SN ₂ are illustrated. In addition, the first super node SN ₁ includes first to fifth nodes N ₁ to N ₅ , and the second super node SN ₂ includes sixth to tenth nodes N ₆ to N ₁₀ . Illustrates including the. Of course, any node can be a super node if certain conditions are met. In addition, nodes that share adjacent nodes or files of a similar genre may form a cluster including one super node and at least one node. This embodiment illustrates two super nodes, namely a first super node SN ₁ and a second super node SN ₂ . In addition, the first super node SN ₁ includes first to fifth nodes N ₁ to N ₅ , and the second super node SN ₂ includes sixth to tenth nodes N ₆ to N ₁₀ . Illustrates including the. Of course, any node can be a super node if certain conditions are met. In addition, nodes that share adjacent nodes or files of a similar genre may form a cluster including one super node and at least one node.

Each of these super nodes and nodes is equipped with a peer-to-peer program including a server program and a client program, and the server program and the client program are included in the same peer-to-peer program to be integrally designed. It is preferable.

In addition, files are exchanged through peer-to-peer programs, each of which contains attribute information in which the information of the file is recorded. At this time, the attribute information includes a tag. Such a tag may include information such as a title of the file, a file type, and a genre. For example, in the case of a music file, MP3 (MPEG Audio Layer-3), the ID3 tag (ID3 TAG) indicates the file attribute. Can be.

The present invention can increase the accuracy of the search results by searching the attribute information of the file in searching the file, and can exchange information with the file without the intervention of other means to activate the information exchange. In addition, the present invention can improve the quality of the search results by evaluating the file and the user sharing the file after the file exchange.

Next, a peer-to-peer file search and sharing method according to the present invention will be described with reference to the accompanying drawings. Duplicated descriptions of the file sharing network of the present invention described above will be omitted or briefly described.

2 to 5 are conceptual views illustrating a peer-to-peer file search method and a sharing method according to the present invention, and FIG. 6 is a flowchart of a peer-to-peer file search method and a sharing method according to the present invention.

2 to 6, a peer-to-peer file search and sharing method according to the present invention may include a step (S ₁ ) of notifying a super node of a shared file of one user, and notifying the super node of a file requested by one user. Step (S ₂ ), a step (S ₃ ) in which the super node notifies one user of another user holding a file requested by one user, and requesting another user a file requested by one user (S ₄ ); The step S ₅ of evaluating a shared file of one user, the step S ₆ of sharing or not sharing a file requested by one user, and a step S ₇ of evaluating another user are included. In addition, this embodiment illustrates a peer to peer system consisting of two super nodes and ten nodes. In this case, two super nodes are defined as a first super node SN ₁ and a second super node SN ₂ , and ten nodes are defined as _first to tenth nodes N ₁ to N ₁₀ . In addition, the first super node SN _{1 is} connected to the first to fifth nodes N ₁ to N ₅ , and the second super node SN _{2 is} connected to the sixth to tenth nodes N ₆ to N ₁₀ . Example of connected with.

The step (S ₁ ) of notifying one user's shared file to the super node, as illustrated in FIG. 2, informs the super node of information of a file to be shared to another user before one user searches for the file. The node stores it.

In the present embodiment, since the first super node SN _{1 is} connected to the first to fifth nodes N ₁ to N ₅ , the first super node SN _{1 is} connected to the first to fifth nodes N ₁ to N. Information of a file to be shared by the user of N ₅ ) is stored. In this case, location information (Internet Protocol Address, IP Address) of the first to fifth nodes N ₁ to N ₅ is also stored in the first super node SN ₁ . Of course, the location information of the second super-node (SN ₂₎ also the sixth to the tenth node (N ₆ to N ₁₀₎ of the file information of the sixth to the tenth node (N ₆ to N ₁₀₎ that the user wants to share the Save it.

In addition, when the first super node SN ₁ connects to the second super node SN ₂ to retrieve the information of the second super node SN ₂ , the information of the second super node SN ₂ is obtained from the first super node SN ₂ . Stored at node SN ₁ . At this time, the second super node (SN ₂₎ of information is a second super-position information of the node (SN _2), the second super node (SN ₂₎ of claim 6 to claim 10 connected to the node (N ₆ to N ₁₀₎ Information of a file to be shared by a user of and location information of the sixth to tenth nodes N ₆ to N ₁₀ .

The embodiment is connected to two super nodes, namely, a first super node SN ₁ and a second super node SN ₂ , a first super node SN ₁ , and a second super node SN ₂ , respectively. The first to tenth nodes N ₁ to N ₁₀ are illustrated. However, the present invention is not limited thereto, and the present invention may be extended to at least one super node and a plurality of nodes respectively connected to at least one super node.

In addition, it is preferable that one user records a tag before notifying the super node of a file to be shared with another user. That is, the tag information of the file to be shared, for example, information such as genre and copyright holder, is accurately recorded so that the accuracy of the search can be increased. Of course, the form for this tag information can be specified by the client program.

In step S ₂ of notifying a file requested by one user to the super node, as illustrated in FIG. 3, the information of a file to be downloaded by one user is notified to the super node. At this time, the step (S ₂ ) of notifying the super node of the file requested by one user is divided into an automatic search step or a manual search step according to a user's selection. In addition, the automatic search step includes selecting a search condition and searching in a super node of a corresponding field.

The step of selecting a search condition sets conditions such as a specific word, a specific sentence, a file type, and a genre of the file to be downloaded.

Specific words or specific sentences included in the file name can be input, and conditions such as file type and genre can be set. In addition, the file type means an extension of a file, and the type of file such as music, video, document, etc. may be classified according to the extension of the file. In addition, for example, a drama may be divided into chapters such as melo, action, etc. among a video file, and one user does not directly search the name of a file by searching for a drama of a specific genre of a specific broadcasting station. If not, you can get search results close to the drama you want to download. Of course, when searching for a specific word or a specific sentence included in the genre and the file name of the file, the accuracy of the search result can be further improved.

The searching in the super node of the corresponding field searches for the file to be downloaded in the super node corresponding to the condition set in the selecting the search condition.

For example, a super node is composed of nodes that share files of a certain genre for each super node, and the first super node SN ₁ can share a document file and the second super node SN ₂ can share a drama. have. In this case, when the user of the first node N ₁ connected to the first super node SN ₁ sharing the document file wants to download the drama, the user of the first node N ₁ shares the drama with the user. 2 Search the file to download by designating the super node SN ₂ as a search target. Of course, when the user of the first node (N ₁ ) connected to the first super node (SN ₁ ) sharing the document file wants to download the document file, the user of the first node (N ₁ ) may share the document file. A file to be downloaded may be searched by designating the first super node SN ₁ as a search target. Of course, the present invention is not limited to this, and may not specify a super node to search.

On the other hand, if one user does not automatically search for a file to be downloaded, step (S ₂ ) of notifying the super node of the file requested by the one user may include inputting a search word, specifying a super node, and specifying a designated super node. Searching at the node.

The step of inputting a search word inputs a word or sentence included in a file name to be downloaded. Of course, the step of inputting a search word is not only a file name but also a file type. In other words, file types such as music, video, document, etc. can be entered together to improve the accuracy of the search results.

The step of specifying a super node designates a super node that shares a file genre to be downloaded.

Each super node shares files of a specific genre and a specific field, or selects a specific super node when the transmission and reception traffic is smooth because it is close to the region. In addition, for this purpose, it is preferable that the client program displays the traffic of the super node to be searched so that the user can identify the super node with smooth transmission and reception traffic.

The searching in the designated super node searches for a file to be downloaded from the super node according to the search condition input by the user and the super node.

In operation S ₃ , the super node notifies one user of another user who has a file requested by one user, as illustrated in FIG. 4, the super node to which one user belongs is another user who has a file that one user wants to download. Notify the work user of the list.

A file including a character or sentence included in the file and a list of other users holding the file are displayed for the user to recognize. The recognition of the list may be implemented by a client program. For example, the client program may display a file and a list of other users who hold the file in the form of a bulletin board.

Requesting a file requested by one user to another user (S ₄ ) includes a file that is determined to be the most similar to the file that the user wants to download from the file displayed in the client program and the list of other users holding the file. Choose. In addition, when a user selects a file as described above, another user who owns the file may check the request of the user.

Evaluating the shared file of one user (S ₅ ) evaluates the value of the file shared by one user.

That is, another user evaluates the value of the shared file notified by one user to the super node, and compares the value of the file requested by one user with the shared file notified to the super node. The value of these files can be assessed by subjective or objective judgments such as necessity, rarity, and so on.

In step S ₆ of sharing or not sharing a file requested by one user, the user may approve or reject sharing of the file requested by the user by evaluating the value of the file shared by the user.

When the value of the shared file notified by the one user to the super node is lower than the value of the file owned by the user, the one user may reject the sharing request from the other user. However, if the value of the shared file notified by the one user to the super node is equal to or higher than the value of the file owned by the user, the one user may accept the sharing request of the other user.

In the step of evaluating the other user (S ₇ ), the other user is evaluated based on the file shared by the other user.

One user checks whether a file shared by another user is a file he / she wants to download, and evaluates another user based on the file. For example, when a file shared by another user is not a file that he / she wants to download, one user may lower another user's evaluation score. Of course, when a file shared by another user is a file that he / she wants to download, one user may increase the evaluation score of another user. For other users, the evaluation may use an evaluation score between 1 and 10 points, for example.

In addition, the user is other score evaluates the user is a super node, belongs to a user, for example, a 1 is written to the super node (SN _1), the first super node for the other user record the (SN ₁₎ The evaluation score is propagated to other super nodes. In addition, the evaluation scores for other users propagated to other super nodes are transferred to and shared with nodes connected to each other super node. Therefore, the user sharing the file can increase the accuracy of the file to be searched to share the correct file so as not to be blocked in the peer-to-peer file sharing system according to the evaluation score.

Of course, the evaluation of other users is based on the evaluation of the accuracy of the file shared by other users (for example, the accuracy of the tag and the sameness of the file name and the contents of the file). You can also rate files shared by other users. In addition, the evaluation of the other user may vary depending on whether the tag of the file shared by the other user is recorded correctly. Of course, the evaluation of the file shared by other users can be recorded in the tag of the file.

As described above, the present invention can activate information exchange by evaluating the value of a file and exchanging a file based on the file.

In addition, the present invention may evaluate the file and the user and block the fake file with the user intentionally sharing the fake file. In addition, the present invention can increase the search accuracy by blocking the fake file and the user who intentionally share the fake file.

Although described above with reference to the drawings and embodiments, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit of the invention described in the claims below. I can understand.
