The correct answer is D. Data tokenization. Data tokenization is a method of protecting PII by replacing the sensitive data element with a non- sensitive equivalent, called a token, that has no extrinsic or exploitable meaning or value. The token is then mapped back to the original data element in a secure database. This w

Explanation

Data tokenization is a method of protecting PII by replacing the sensitive data element with a non- sensitive equivalent, called a token, that has no extrinsic or exploitable meaning or value. The token is then mapped back to the original data element in a secure database. This way, the PII is not exposed in the data processing or storage, and only authorized parties can access the original data element. Data tokenization is different from encryption, which transforms the data element into a ciphertext that can be decrypted with a key. Data tokenization does not require a key, and the token cannot be reversed to reveal the original data element.
