Data Anonymization
Data anonymization is the process of altering or removing personally identifiable information from datasets to protect individual privacy while preserving the data's overall utility for analysis. This technique is essential in modern digital ethics, helping organizations comply with regulations like GDPR and HIPAA, yet it often involves a delicate balance between privacy and the need for accurate insights in fields such as AI and big data.

A famous case involving data anonymization is the 2000 release of anonymized medical records from Massachusetts Group Insurance Commission, which researchers re-identified by cross-referencing with voter rolls, showing that even 'anonymized' data can be deanonymized with just a few variables—highlighting how this technique isn't foolproof and has shaped privacy laws globally.
