Description

Method and device for interfering with distribution of torrent-based copyright infringement content {METHOD AND APPARATUS FOR DISRUPTING DISTRIBUTION OF TORRENT-BASED PIRACY CONTENTS}

This disclosure relates to torrent technology. More specifically, the present disclosure relates to a method and device for interfering with the distribution of torrent-based copyright infringement content.

Torrent refers to a protocol or program that divides files existing on the Internet into several pieces and shares them directly between users. Unlike existing P2P services, torrenting is characterized by a 'one-to-many' sharing method that receives file information divided into pieces from multiple users rather than receiving the entire data or program from one partner. The more users there are, the faster the download speed. becomes faster.

At this time, the roles of the sender and receiver of data change in real time, and when the user is sharing a file, the server acts as the sender (uploader), and when downloading a file from another user, it acts as the client as the receiver (downloader). Do it. Once the file has been shared to some extent, it acts as both a server and a client, uploading and downloading pieces of the file. If you install the torrent software on a terminal such as a PC and run the downloaded seed file, you can download data from users around the world who have the corresponding file fragment. Alternatively, you can download the desired file by entering the code address of a specific file using a magnet address.

There is no doubt that torrent-related technology is a groundbreaking technology, but the damage caused by the illegal distribution of copyrighted content in the torrent environment is serious, and millions of online illegal copies have been accumulated over the years, and torrenting is the most distributed distribution channel of illegal copies. It is currently in the path.

Figure 3 is a sequence diagram showing a method of preventing the distribution of torrent-based copyright infringement content according to the present disclosure. Figures 4 and 5 are diagrams for explaining the process of transmitting a RUDP Flooding packet to a seeder sharing illegal works according to the present disclosure. 6 to 8 are diagrams for explaining a poisoning method for a tracker supporting various protocols according to the present disclosure. FIG. 9 is a diagram illustrating a method for delaying the search for illegal works by adding a fake seeder to a tracker according to the present disclosure. While explaining FIG. 3, necessary portions will be described with reference to FIGS. 4 to 9.

first of all, The processor 190 of the device 100 for preventing the distribution of torrent-based copyright infringement content can check illegally written content (S310).

The processor 190 can monitor the torrent environment and check for illegally created content. The processor 190 may check whether a specific file is copyright infringement content due to illegal copying, etc. based on user input.

In an optional embodiment, the processor 190 may provide rewards to peers who report illegal works in a torrent environment. Various information or points may be provided as rewards to peers who report illegal works.

The processor 190 may transmit a number of RUDP Flooding packets including a SYN Flag to a seeder that shares copyright infringement content (S320).

Here, RUDP is Reliable UDP, a communication protocol that complements the shortcomings of UDP. Specifically, in the case of RUDP, the order of data can be guaranteed, the arrival of data can be guaranteed, and the integrity of data can be guaranteed.

Referring to FIG. 4, the processor 190 of the torrent-based copyright infringement content distribution obstruction device 100 sends a number of RUDP Flooding packets including a SYN Flag to the seeder 200 that is sharing or attempting to share copyright infringement content. Can be transmitted.

Then, the seeder 200 that shares the illegal work must repeatedly transmit the ACK Flag (S420, S440) in response to receiving the SYN Flag (S410, S430), so the data sharing speed gradually decreases.

In an optional embodiment, the processor 190 may perform a hash collision process and store the data set when an illegal work is discovered, or may modify a shared file using a hashset DB when an illegal work is discovered. That is, the processor 190 may attempt hash collision.

In an optional embodiment, the device 100 for preventing the distribution of torrent-based copyright infringement content may be the same device as the peers storing the torrent program, depending on the implementation.

After step S320 of FIG. 3, the processor 190 may gradually reduce the seeder's data sharing speed to a preset speed and then block sharing of content (S330).

Referring to FIG. 5, when the torrent-based copyright infringement content distribution obstruction device (100, SOP) repeatedly transmits a SYN Flag to the seeder (SD3), the peer including a plurality of reachers who download data from the seeder (SD3) For the group (PR1), data sharing may be interrupted even though the Internet connection is normal.

After step S330 of FIG. 3, the processor 190 may transmit a command to remove a seeder related to content uploaded to the tracker to the tracker (S340).

A tracker GET request sent to the tracker may include multiple parameters, including info_hash, peer_id, ip, port, uploaded, downloaded, left, and event parameters.

Specifically, the info_hash parameter is a 20-byte sha1 hash of the bencoded form of the info value in the metainfo file, and may be a string in the metadata file. The peer_id parameter is a string of length 20 that the downloader uses as its ID. Each downloader can randomly generate its own ID when starting a new download. The ip parameter is an optional parameter that provides information about the IP (or DNS name) where the peer is located. The Port parameter is the port number used by the peer to listen. Typically, downloaders can use a specific port (such as 6881) to listen. The uploaded parameter is the total uploaded capacity so far and can be encoded as a decimal ASCII code, and the downloaded parameter is the total downloaded capacity so far and can be encoded as a decimal ASCII code. The left parameter is the capacity that the peer needs to download more, and can be encoded in decimal ASCII code. Since some of the downloaded data may fail the integrity check and need to be downloaded again, the value of the left parameter cannot be calculated from the value of the downloaded parameter and the length of the file.

Additionally, the event parameter is an optional parameter that has a value of one of started, completed, or stopped. The event parameter has a value of started when a download first starts, and a value of completed when the download is completed. Additionally, event can have the value stopped when downloading is stopped.

Referring to FIG. 6, the processor 190 may change the event parameter of the tracker GET request message to the stopped state and transmit it to the HTTP-based tracker (TRK1). Then, the tracker (TRK1) can delete the seeder information (e.g., parameter values such as peer_id, info hash, ip, port, etc.).

Referring to FIG. 7, the processor 190 may change the event parameter of the tracker GET request message to the stopped state and transmit it to the HTTPS-based tracker (TRK2). Then, the tracker (TRK2) can delete the seeder information (e.g., parameter values such as peer_id, info hash, ip, port, etc.).

Referring to FIG. 8, the processor 190 may change the event parameter of the tracker GET request message to the stopped state and transmit it to the UDP-based tracker. Then, the UDP-based tracker can delete the seeder information (e.g., parameter values such as peer_id, info hash, ip, port, etc.).

After step S340 of FIG. 3, the processor 190 removes seeders related to illegal copyrighted content from the tracker and adds one or more fake seeders corresponding to the removed seeders to the tracker to prevent illegal distribution of content that will occur in the future. It can be prevented (S350).

In the case of peers searching for illegal works on torrents, it takes time to find seeders holding illegal work content due to fake seeders, which may cause search delays.

In an optional embodiment, the processor 190 may transmit a command to remove the fake seeder from the tracker to the tracker when a predetermined time elapses. In addition, when the fake seeder is removed from the tracker, a notification can be provided to the device 100 for preventing the distribution of torrent-based illegal copyrighted content. When sharing of illegal works begins again, the processor 190 may transmit a RUDP Flooding packet to the sharing seeder.

As described above, the processor 190 uses RUDP Flooding packet transmission, a poisoning method to remove seeders sharing illegal works in the tracker, and a method to add fake seeders to the tracker to prevent the distribution of illegal works. It can be prevented.

Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium that stores instructions executable by a computer. Instructions may be stored in the form of program code, and when executed by a processor, may create program modules to perform operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

Computer-readable recording media include all types of recording media storing instructions that can be decoded by a computer. For example, there may be read only memory (ROM), random access memory (RAM), magnetic tape, magnetic disk, flash memory, optical data storage device, etc.

As described above, the disclosed embodiments have been described with reference to the attached drawings. A person skilled in the art to which this disclosure pertains will understand that the present disclosure may be practiced in forms different from the disclosed embodiments without changing the technical idea or essential features of the present disclosure. The disclosed embodiments are illustrative and should not be construed as limiting.
