 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 value1. 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 element2. References: 1: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 5, page 2812: CISSP For Dummies, 7th Edition, Chapter 10, page 289.
