Which of the following allows a data analyst to send out a spreadsheet containing sensitive information without revealing personal details?

Using a UUID might pseudonymize an identifier, but it doesn't guarantee the removal of all other PII that could lead to re-identification or ensure personal details are not revealed.

Redacting all PII (Personally Identifiable Information) involves removing or obscuring any data that could directly or indirectly identify an individual from the spreadsheet. This directly achieves the goal of sharing sensitive information without revealing personal details, as the identifying elements are no longer present.

Adding access controls limits who can view the ID column, but it does not remove personal details from the spreadsheet itself for authorized viewers who receive it.

Encrypting the spreadsheet protects its contents from unauthorized access, but once decrypted by an authorized recipient, all personal details would be fully visible.
