Correct answer: Pseudonymized signals – identifiers are made into unidentifiable strings of data..
Why this is the answer
Pseudonymized signals help protect privacy by replacing direct identifiers with non-identifying strings. Amazon Marketing Cloud uses privacy-safe inputs and controls so analysis can occur without exposing individual customer identities. This allows advertisers to evaluate aggregated patterns while reducing the risk of re-identification. It is a core clean room mechanism for enabling collaboration and measurement with protected data.
