解説
問 23
Incorrectア
The new-feature emails are sent only to “users who requested them.” This is a method of sending information only to those who gave prior consent (requested it), an example of “opt-in,” the opposite concept of opt-out. It is not the form of sending by default and then excluding those who refuse, so it is wrong.
- イ
正解 Opt-out means a method in which, without assuming the person’s prior consent, information is used or listed in advance, and the use is stopped only once the person objects and asks to stop. In choice イ, the person’s name was listed at their home’s location on the residential map without their consent (i.e., listed by default); upon noticing it, the person contacted the publisher and had the listing removed. This flow of listing in advance and stopping it once the person requests is exactly opt-out, so イ is correct.
Incorrectウ
Because the payment procedure was troublesome, the person stopped the purchase operation partway — this is merely a purchase cancellation (so-called cart abandonment). It is not about refusing or stopping the use of personal information, and is unrelated to the concept of opt-out, so it is wrong.
Incorrectエ
Replacing names and addresses with random values so that customers cannot be identified is processing that makes individuals unidentifiable — an example of “anonymization.” This is a different idea from opt-out, which stops use at the person’s request, so it is wrong.
ここがポイント
- Definition of opt-out: a method that uses or lists information in advance without the person’s prior consent and stops once the person requests refusal or cessation. In contrast, a method carried out only toward those who have given prior consent is “opt-in.”
- Distinguishing it from confusing concepts: anonymization (replacing names, etc., with random values so individuals cannot be identified) and purchase cancellation (cart abandonment) are not opt-out.
