Data anonymization

Definition

Data anonymization is the process of transforming personal data in such a way that individuals cannot be identified from the data, either directly or indirectly. This technique aims to protect individual privacy while still allowing organizations to analyze and use data for various purposes, such as research and analytics. Effective data anonymization balances the need for data utility with the ethical obligation to safeguard personal information.
