解説
問 8
Incorrectア
The combination of a and b. Action b is appropriate, but action a, “using a My Number as a control number for managing personnel evaluation information,” departs from the legally defined purposes (social security, taxation, disaster response) and is a use for an unauthorized purpose, so it is not appropriate. Because it includes the inappropriate action a, this option is wrong.
Incorrectイ
This treats a, b, and c all as appropriate, but action a is a use for an unauthorized purpose and is not appropriate. Because it includes the inappropriate action a, this option is wrong.
Incorrectウ
This lists only b, but the identity confirmation in c is also an appropriate action required by the Number Act, and it is left out. Because it does not list all of the appropriate actions, this option is wrong.
- エ
正解 The My Number Act (Number Act) strictly limits the purposes for which a My Number may be used to the legally defined tasks of social security, taxation, and disaster response. Action b, “recording an employee’s My Number on a report submitted to the tax office,” is itself a legally defined tax-related task and is therefore appropriate. Action c, “when receiving a My Number, confirming that the number belongs to that person,” falls under the identity confirmation (number confirmation plus identity verification) that the Number Act requires, and is also appropriate. Therefore the appropriate actions are the two items b and c, and the correct answer is エ.
ここがポイント
- The use of a My Number is limited to the legally defined tasks of social security, taxation, and disaster response; diverting it to purposes such as an internal personnel management number (use for an unauthorized purpose) is prohibited.
- When obtaining a My Number, an identity confirmation consisting of number confirmation and identity verification is mandatory.
