よくある質問：個人情報の保護について｜デジタル庁

This page presents FAQs about personal information protection in Japan's My Number system administered by the Digital Agency. It clarifies that sensitive medical information is not stored on the My Number Card's IC chip, and that personal information is managed in a decentralized manner across different agencies rather than being centrally managed. The system incorporates multiple security measures including access controls and encrypted communications. Even if a My Number is leaked, it cannot be misused alone since procedures require strict identity verification. The page also addresses differences from identity theft cases in the United States and South Korea.
