Secure ID management for social security and tax number system

The Japanese government will adopt the Social Security and Tax Number System. The system is beneficial, but it is necessary to consider how to prevent abuse of the system. To prevent any abuse of the system, we developed a secure device which manages IDs such as Social Security and Tax Number. This secure device safely manages IDs, and can increase efficiency of audit. In this paper, we evaluate the Japanese Social Security and Tax Number System by fault-tree analysis and summarise the proposed ID-management device.
