Beware of copyright infringement with P2P file sharing apps and software

What is P2P file sharing app/software?

Do you use any app or software that offers all-you-can-watch movies or a function to save your favorite videos?
Such apps and software may be using a structure called “peer-to-peer (P2P)” behind the scenes.
In such a case, you could unknowingly commit copyright infringement, which may result in you being billed for expensive damage compensation costs.
You may not be concerned with the topic because you do not know much about it. However, to protect yourself and your family, let’s learn about the P2P structure and how to prevent the associated risks.

P2Pファイル共有ソフトとは?

A structure that causes you to receive and distribute at the same time

P2P file sharing apps/software use a structure that allows you to directly exchange files with an unknown number of people over the internet. BitTorrent is one of the popular apps/software. The key feature of this structure is that once a user downloads (or receives) a file, it simultaneously uploads (or distributes) that file to other people.
This means that your computer or smartphone automatically takes on the role of a file distribution hub for people around the world.

You can be the “offender” without knowing it

Most users only want to watch a video or save a specific file and do not intend to distribute files to other people.
However, as long as you use such an app or software, you will unintentionally be distributing copyright content (video, comics, music, etc.) without permission.
This is an act of copyright infringement – an illegal act committed without the permission of the copyright holder.

The number of damage claims due to copyright infringement is surging

When you connect to a P2P network, your communication record (such as IP address) is logged.
Based on the Information Distribution Platform Act (formerly the Provider Liability Limitation Act), copyright holders can use this communication record to request that the internet service provider disclose information about “who is subscribing to the line or who is using the communication”.
As a result, the subscriber’s name and address can be identified, and the number of expensive damage claims is surging.

How to prevent

There are three ways to prevent becoming involved in such unintentional trouble.

対策方法

Beware of “free” and “all-you-can-watch” apps

Please beware of unofficial, unverified “free movie apps” and “file saving tools”.
Those apps may not include the word “P2P” or “Torrent” in their names, but may use the structure behind the scenes.
The most effective countermeasure is to “not download” or “not to allow the downloading of illegal files.”

Decide on family rules

Cases have been reported where a child or anyone who lives with the subscriber installs the app or software for convenience.

  • Make a promise to watch videos only on official, authorized apps.
  • Configure the settings to prevent the installation of apps or software on family computers and smartphones.

It is important for all family members to understand the risks of P2P file sharing apps and software, and have a rule not to use them.

Check your device settings

It is also important to be aware of peripheral devices such as Wi-Fi routers and network attached storage (NAS) devices.
Some products include a file sharing function as a default setting.
If such a function is enabled, you are at risk of files being distributed at any time, even when the computer is not in use.
Please check your device’s manual and turn off any unnecessary file sharing function.

Where to find help when you are uncertain
