Answer: Anonymization

## Explanation **Anonymization** is the correct answer because: - **Anonymization** refers to the process of irreversibly altering personal data so that the data subject cannot be identified directly or indirectly - It is a permanent process that removes all identifying information - Once data is anonymized, it is no longer considered personal data under privacy regulations like GDPR **Why the other options are incorrect:** - **Tokenization**: This involves replacing sensitive data with non-sensitive equivalents (tokens) that can be reversed with the proper key - **Pseudonymization**: This replaces identifying fields with pseudonyms, but the original data can still be recovered using additional information - **Binning**: This is a data preprocessing technique for grouping continuous data into categories, not specifically for privacy protection The key distinction is that anonymization is **irreversible**, while pseudonymization and tokenization are reversible processes that still maintain the ability to identify individuals under certain conditions.
