問題文
A healthcare provider's chat must hide patient identifiers from the representative's screen on asynchronous channels, and must hide internal notes from the patient. Which design detail matters most?
選択肢
- The two masking directions behave differently on asynchronous channels: masking customer data affects only the representative's interface there, while masking representative data affects both parties.
- Masking is not available for asynchronous channels at all, so the provider must move the conversation to live chat before any patient identifier can be hidden.
- Masked values are preserved in the stored transcript even though they are hidden on screen, so a separate retention rule is needed to keep the identifiers out of the record.
- Both masking directions behave identically on every channel, so a single rule with the patient identifier pattern covers both of the provider's requirements at once.
