委託事業における個人情報漏えいについて｜厚生労働省

This page announces a personal information disclosure incident in a commissioned research project on blood product usage appropriateness conducted by Japan's Ministry of Health, Labour and Welfare. PDFs posted on the ministry's website had masking that could be removed by certain operations, exposing patient information including names, addresses, and blood types. Information for 32 patients across Kagoshima, Hyogo, and Ishikawa prefectures was affected. The ministry has corrected the masking and committed to preventing recurrence through enhanced attention to personal information handling and stricter pre-publication verification of reports.
