Anonymization is a technique that removes or modifies personal data in such a way that it can no

longer be attributed to a specific data subject. Anonymization can be achieved by various methods,

such as encryption, pseudonymization, aggregation, generalization, etc. When using anonymization

techniques to prevent unauthorized access to personal data, the most important consideration to

ensure the data is adequately protected is that the key must be kept separate and distinct from the

data it protects. The key is a piece of information that is used to reverse the anonymization process

and restore the original personal data. The key must be stored and managed in a secure location that

is different from where the anonymized data is stored and processed. This way, even if the

anonymized data is compromised, the key cannot be accessed or used to re-identify the data

subjects. Reference: : CDPSE Review Manual (Digital Version), page 29
