Data anonymization is done for the purpose of protecting an individual’s or company’s private activities while maintaining the integrity of the data gathered and shared.
When should data be anonymised?
Anonymised data means that all identifiers have been irreversibly removed and data subjects are no longer identifiable in any way. Information is fully anonymised if there are at least 3-5 individuals to whom the information could refer.
How do you implement Anonymization?
Data anonymization is done by creating a mirror image of a database and implementing alteration strategies, such as character shuffling, encryption, term, or character substitution. For example, a value character may be replaced by a symbol such as “*” or “x.” It makes identification or reverse engineering difficult.

What is group based anonymization?
Group based anonymization is the most widely studied approach for privacy preserving data publishing. This includes k-anonymity, l-diversity, and t-closeness, to name a few. The group based anonymization approach basically hides each individual record behind a group to preserve data privacy.
What is anonymization and how does it work?
Anonymization is designed to make it impossible (or extremely impractical) to connect personal data to an identifiable person. Organizations can then use, publish, and share that data without requiring permission. Anonymization permanently replaces sensitive data with a substitute value—it’s a form of data tokenization without the token vault.

What is the difference between anonymization and pseudonymization?
Pseudonymization: The idea behind this method is to replace personally identifiable elements of data entry with artificial records known as pseudonyms. Whereas anonymization is an irreversible process, pseudonymization allows for re-identifying the cloaked data via specific clues at a later point.
What happens to personal data once it has been anonymized?
