[Consultation] Review of issues related to the anonymization of user IP addresses and public disclosure

Law firm Veat reviewed the issue of A’s ‘user IP address anonymization and public disclosure’ regarding the game-related community software development company.

A contacted us to inquire about whether they could take measures to anonymize part of their IP addresses and then publicly disclose them, regarding their efforts to manage malicious posts and comments within their bulletin boards.

In response, Law firm Veat reviewed the re-identification potential of anonymized IP addresses, providing advice on ▲ reducing the disclosure scope from public disclosure to administrator disclosure ▲ requiring confidentiality agreements for IP address administrators ▲ adding relevant content to their personal information processing policy. Furthermore, we concurrently reviewed necessary forms, including confidentiality agreements, in response to the views of agencies such as the Ministry of Interior and Safety.
