An organization is participating in an industry benchmarking study that involves providing customer transaction records for analysis Which of the following is the MOST important control to ensure…

Nondisclosure agreements (NDAs) are contractual agreements to protect data but do not technically prevent the re-identification of individuals if the shared data contains PII.

Data anonymization is the process of removing or modifying personally identifiable information (PII) from data sets so that the individuals involved cannot be identified. This is crucial for privacy in benchmarking studies, as it allows the data to be used for analysis without exposing customer identities.

Data cleansing focuses on identifying and correcting errors or inconsistencies in data, not primarily on removing PII for privacy purposes.

Data encryption protects data confidentiality during transit or storage but can be decrypted by authorized parties, meaning the PII is still present and viewable if accessed.
