解説

問 17

  • ア

    正解 The Provider Liability Limitation Act (now the Information Distribution Platform Response Act) is a law that, when someone's rights (such as reputation, privacy, or copyright) are infringed by information distributed over the Internet, both defines the scope of a provider's liability for damages and covers responses such as requests to disclose sender information and requests to delete the information. In case a, personal information such as a name was posted on an electronic bulletin board, a place that an unspecified number of people can view, infringing on an individual's rights, which is exactly an infringement of rights caused by the distribution of information. Therefore, the only case that can be subject to the provider's response obligation is a, and the correct answer is “ア”.

  • Incorrectイ

    This option lists all of a, b, and c, but b and c fall outside this law. Case b is a malware infection, not an infringement of rights caused by the distribution of information, and case c is a matter of unauthorized access. Therefore it is incorrect.

  • Incorrectウ

    This option lists a and c, but case c involves using someone else's user ID and password without permission to gain access, a case of unauthorized access that falls under the Unauthorized Computer Access Act, not the Provider Liability Limitation Act. Therefore it is incorrect.

  • Incorrectエ

    This option lists only c, but case c is one of unauthorized access and falls outside this law. Conversely, case a, which is an infringement of rights caused by the distribution of information, is missing, so it is incorrect.

ここがポイント
  • The Provider Liability Limitation Act (Information Distribution Platform Response Act) targets infringements of rights caused by the distribution of information on the Internet, and defines the limitation of a provider's liability for damages, disclosure of sender information, and deletion responses. Malware infection and unauthorized access fall outside its scope.
  • Distinguishing the related laws: infringement of rights by posting information = Provider Liability Limitation Act; access using someone else's ID and password without permission = Unauthorized Computer Access Act.
