Handling of information

Some of the things we must be especially careful of regarding internet-related trouble include violations of intellectual property rights, improper use of SNS, and virus infection caused by replying to suspicious emails, opening attachments, and accessing suspicious websites (leakage of personal information). In most cases, small misunderstandings can cause a conflict even if the person had no intention to do so, leading to unexpected trouble. Use the internet while keeping social rules and common sense in mind.

Violation of intellectual property rights

Most internet-related incidents that become issues in universities are a violation of intellectual property rights.

Intellectual property rights refer to patents, utility model rights, breeder’s rights, design rights, copyrights, trademark rights, etc. However, the scope of illegality has been expanding in recent years. One example is downloading with one click. In some cases, this simple act can be applicable to a violation of copyright. In addition, illegally sharing files of music and videos is a criminal act. Whether it is in Japan or not, downloading illegally uploaded music/videos is punishable with “imprisonment for a term of up to two years, a fine of up to two million yen, or both” according to the Copyright Act.

“They will never find out if I don’t say anything” would not work in this case. There are organizations not only in Japan and the U.S. but throughout the world that continuously monitor the internet to identify those who illegally share files.

Virus infection caused by replying to suspicious emails, opening attachments, and accessing suspicious websites

Virus emails are sent under various subject names. When you execute (double-click) the attached file, these programs infect your device with PC remote operation viruses. Some viruses cannot be detected by virus checking software.

While accessing suspicious websites is not prohibited due to it being at one’s own risk, we must fully understand the risks that come with it. Especially, carelessly clicking links within websites and downloading software are extremely dangerous.

Smartphones are being rapidly disseminated, but smartphones have the same kind of features as computers. There are also a number of unlawful applications that steal personal information, and there have been over 11.9 million cases in which personal information (such as phone numbers and email addresses) was leaked. Review the applications in your smartphone, understand the characteristics of smartphones, and use them carefully.



  • Do not access links (URLs) included in emails from unfamiliar senders. Do not send any replies.
  •  In case of attachments, there have been reported cases of those that appear to be Word files at a glance but have the extension “.exe” or are in fact compressed files with the extension “.lzh.” If you receive these suspicious files from unfamiliar senders, never open them.
  • If you opened an attachment or your PC was infected by a virus (a strange message is displayed or things don’t seem to be working normally), immediately unplug the PC network cable or turn off the wireless LAN connection feature to prevent the infection from spreading. Then, consult consulting services, such as the WPO (Waseda Portal Office), etc.

Improper use of SNS

Illegal acts and wrongful acts are not acceptable. However, there have been many cases in which people have confessed their own criminal acts through SNS (such as LINE, Facebook, and Twitter) in recent years. It seems unbelievable, but there are actually students among you who write about underage drinking/smoking, shoplifting, sexual harassment, and cheating (on university tests).

It seems that many of them either don’t understand that SNS is open to the entire world or have overconfidence about the anonymity of the internet. Even if the personal information is fragmented, individuals can be identified by connecting them in some cases. Also, understand that information disclosed on the internet can never be completely deleted.

Misunderstanding caused by exchanges of written words

People can create disagreements, discrepancies, and conflicts through wording choices in communication. Furthermore, if you are communicating with an unspecified large number of people only through written words, “flaming” can occur any time. Once a flame is ignited, repeated remarks can fuel the flame, causing it to burn more.

When you transmit information, clearly and articulately express your intention as much as possible. On the other hand, when you are receiving information, try to only read the words as they are written without reading between the lines. If any misunderstanding still occurs, it is important that you don’t continue exchanging only written words.

Cautions when using computers

  • Do not let external parties use university computers.
  • Do not lend your Student ID or ID/password to third parties.
  • Do not post test questions, report problems, or answers on websites.
  • When you upload a file to a website, etc. or download a file from a website, etc., always perform a virus check.
  • When storing important data, such as name list and photos, store it in memory media with security features, such as passwords and fingerprint authentication.
  • Do not use unauthorized copies of products using file exchange software.
  • Do not illegally copy purchased software. Always keep the OS and software, such as applications, updated and introduce security software, such as antivirus software.
  • Also keep your smartphone/tablet PC locked with passwords.

Counseling service in case of trouble

If you find yourself in trouble due to using the internet, etc. or if you feel that you may personally be in trouble, immediately consult your school office.
