Question

Which of the following MOST effectively ensures data privacy when sharing datasets for machine learning (ML) model training?

Options

AIntegrity checks
BData anonymization
CAttribute-based access
DData encryption in transit

Explanation

Anonymization (de-identification) is the PET that removes or irreversibly transforms identifiers so individuals are not identifiable, enabling safer secondary use and sharing. Controls like encryption in transit (D) and attribute-based access (C) restrict access or protect data in motion but do not prevent reidentification once data are accessed. Integrity checks (A) protect correctness, not privacy. Key CDPSE-aligned phrasing (short extract): "Anonymization... renders personal data not identifiable to a data subject."
