Description

Paid P2P file sharing service method {PEER TO PEER FILE SHARING SERVICE WITH FEE}

The present invention relates to a file sharing method, and more particularly, to a method for enabling billing in a P2P type file sharing service.

Recently, as the use of the Internet spreads, various digital data is rapidly shared through downloading from web pages, and multimedia data such as mp3 is required to be easily searched by individuals in a peer-to-peer manner. You can search for and download easily.

However, such P2P file sharing has some problems. That is, it is illegally distributed without paying the copyright holder or the neighboring copyright holder. Therefore, the services themselves cannot be stable because they are subject to regulation in some way. In addition, there is no concept of incentive for file providers, so they download only files shared by others without sharing their own files. In addition, the shared music files exist in various types of file names for the convenience of each individual, and searching based on the file name is impossible, and the ID3 TAG existing in the mp3 itself also does not adhere to the specified format. There is no choice but to come out.

In addition, existing music producers (author's neighbors) are aware of the limitations of relying on illegal distribution of digitized music for legal distribution, and they are focusing on selling positive digital music using internet websites. Several sites offer paid MP3 services. However, since free downloads coexist, real users do not spread, and many problems, such as DRM (Digital Right Management), are not solved. In addition, new releases (CDs) are technically blocked from illegal copying (i.e., they run in an audio CD player but not in a PC CD driver). There is also no solution that makes it impossible to make a legal copy for a solution.

The present invention is to solve the above-described problems, enabling the billing for digital music files distributed in the P2P form, so that service companies and users can provide and use the service legitimately, and the copyright holder and the neighboring rights holder is a legitimate copyright The purpose is to get paid.

In addition, an object of the present invention is to provide a suitable incentive not only to copyright holders and copyright holders but also to file providers for digital music files distributed in a P2P form, to facilitate the monetization of digital music files.

In addition, an object of the present invention is to improve the service convenience by inducing the use of standard information for digital music files distributed in a P2P format.

In order to achieve the above object, the present invention provides a paid P2P file sharing service method comprising the steps of: receiving shared file information of a provider client registered and logged in; Establishing a shared file information database according to the received shared file information; Identifying a copyright holder for the shared file information from the copyright holder database and storing the copyrighted information in the shared file information database; Sending a shared file registration confirmation to the provider client; Receiving a search request from a buyer client that is registered and logged in; Transmitting a search result to the buyer client by referring to the shared file information database stored and received from all logged-in provider clients; Receiving a file download request for a specific provider client from the buyer client; Retrieving the purchase point information of the buyer from a point information database to determine whether a download is possible; Recording download start log data when the buyer client starts receiving a file from the supplier client; Recording download completion log data when the buyer client completes receiving the file; And recording charging data for the supplier, the buyer, and the copyright holder based on the download completion log data.

Hereinafter, a paid P2P file sharing method according to the present invention will be described with reference to the accompanying drawings.

1 is a schematic diagram of a paid P2P file sharing system according to the present invention. When the provider client 20 registers its multimedia content file with the server 60, the information is stored in the server database 80. When the purchaser client 10 sends a search keyword to the server 60, the server 60 retrieves the result matching the condition from the server database 80 and sends the result to the purchaser client 10. When the purchaser client 10 selects a desired file and transmits the request, the direct connection is made with the supplier client 20 to receive the file. When the transfer is complete, the purchaser client 10 informs the server 60 that the completion is completed, and the server 60 updates the point information for each of the buyer, supplier, and copyright holder of the server database 80.

2 is a diagram of a server database 80 of the server 60, which includes a file information database 30, a point information database 40, a transfer record database 50, and a copyright information database 70. As shown in FIG.

The file information database 30 is a database in which the information is stored when a user (supplier) who wants to download his or her file registers a file to be shared. Each file is given a unique registration ID, which is also stored on the client side, which is the main parameter for the job requested by the server 60.

The point information database 40 is a database that manages point information of each user. Points are virtual units of currency owned by users in advance, and all transactions in this system are made through points.

The transfer record database 50 is a database for storing file transfer log records of users, and includes download start log data and download completion log data. That is, when a buyer starts a download, the buyer ID and download start time and the unique registration ID and supplier ID of the file to download are stored as download start log data, and when the buyer completes the download, the buyer ID and download end time Download and save the unique registration ID and provider ID of the file you are downloading. Such log data is used to determine, for example, billing-related retransmission of a file that has already been received and a download incomplete during download.

The copyright information database 70 is a file containing information about the original copyright holder and / or the neighboring copyright holder of the multimedia content file registered by the users. The server 60 uses the information sent when the provider registers the file to inquire the copyright holder and / or the neighboring copyright holder of the file and records the file in the file information database 30.

3 is a flowchart illustrating an overall flow of file registration of a provider client and file purchase of a buyer client as an embodiment of a paid P2P file sharing method according to the present invention.

That is, when a registered provider logs in and designates a file to be shared among the files stored in the provider client and transmits it, the server 60 receives the shared file information (S1). Next, a file information database 30 is constructed according to the received shared file information (S2). Next, the copyright holder for the shared file information is identified from the copyright information database 70 and stored in association with the file information database 30 (S3). Next, the shared file registration confirmation is transmitted to the provider client (S4). Next, a search request is received from the buyer client (S5). Next, the search result is transmitted to the purchaser client by referring to the stored file information database 30 received from all the supplier clients (S6). A file download request for a specific provider client is received from the buyer client (S7). Next, it is determined whether or not a download is possible by inquiring the point of purchase information of the buyer from the point information database 40 (S8), if possible, that is, if the purchaser has a purchase point, the buyer client files from the supplier client. Start receiving and record download start log data at this time (S9). If you do not have a purchase point, you will be notified that the download is not possible. Next, when the purchaser client completes receiving the file, the download completion log data is recorded (S10), and billing data for the supplier, the buyer, and the copyright holder are recorded based on the download completion log data (S11).

Hereinafter, a detailed function will be described with reference to the accompanying drawings.

4 is a flowchart of a process in which a provider registers a multimedia content file in his PC with a server in order to share his file with other users. When the provider client 20 requests a registration for the file selected by the provider, the information of the file (file name, file size, information of the title of the id3 tag, artist, etc. in the case of an mp3 file) and owner information are sent to the server 60. It is sent and stored in the file information database 30 (step 100). At this time, the copyright holder of the corresponding file is found in the copyright information database 70 based on the information of the sent file and stored in the file information database 30 together. If the storage is successfully completed, a confirmation message is sent back to the provider client 20 to confirm that the registration has been successfully performed (step 110).

5 is a flowchart of a search process for determining a multimedia content file that a buyer wants to download. When the buyer client 10 sends a search request message to the server 60 together with the search keyword (step 120), the server 60 searches the file information database 30 and sends the file information that satisfies the condition to the buyer client 10. (Step 130).

6 is a flowchart illustrating a process of actually transmitting a multimedia content file between the provider client 10 and the purchaser client 20. The buyer client selects a multimedia content file to be downloaded from the search results shown as a result of the process of FIG. 4 and requests a download to the server. (Step 135) The server, which has received the transmission request, requests the client 10 from the point information database 40. If there are fewer points than the points to be paid and the points currently have to be paid, the non-transmitting message is sent (step 137). (20) and the provider client 10 sends a connection command message to connect to the virtual ip side to the actual ip side (steps 140 and 150). And the server 60 receives the file receiving start message to the buyer client (10) The client sends a file start message to the provider client 20 (steps 180 and 190). When the client 10 starts to receive the file, it notifies the server 60 that the transmission has started, and the server 60 records the transmission history database 50 that the transmission has started (step 200). (10) and the client client 20 is made through a direct connection (step 210) When the file reception is complete, the buyer client 10 notifies the server 60 that the transfer is complete and the server 60 transfer database In step 50, a record indicating that the transmission is completed is left (step 220). The server 60 then enters the point processing process. If the transmission is interrupted due to the blocking of the supplier / buyer or other network problems before the transmission is completed, the buyer client 10 notifies the server 60 that the transmission has been canceled and the server 60 transmits the transmission history database 50. Keep a record of the cancellation.

7 is a flowchart showing a point processing process (charging process) after the transmission is made. The server 60 receives the purchaser ID and the registration ID of the file while receiving the transmission completion message from the buyer client 10 in step 220. The owner ID (supplier ID) and copyright holder ID of the file are obtained from the file information database 30 using the registration ID of the file, and the buyer's points are subtracted by the corresponding amount of the file from the point information database 40 using the supplier ID. The points of are added by a certain ratio, and the points of copyright holders are also added by the corresponding royalty rate. The buyer client 10 and the supplier client 20 are then notified of each point change so that the buyer and the supplier can immediately check the operation (step 230).

According to the present invention, digital contents, in particular, digital sound sources are distributed in a P2P form, and the billing thereof is possible, so that service providers and users can provide and use the service legitimately, and copyright holders and neighboring rights holders can obtain a fair royalty fee. It is intended to be paid.

In addition, an object of the present invention is to provide a suitable incentive not only to copyright holders and copyright holders but also to file providers for digital music files distributed in a P2P form, to facilitate the monetization of digital music files.

In addition, an object of the present invention is to improve the service convenience by inducing the use of standard information for digital music files distributed in a P2P format.
