"Privacy preservation" in data handling refers to the processes and techniques employed to protect personal information from unauthorized access and misuse. This involves implementing strategies to ensure that data collection, storage, and processing comply with data protection regulations such as GDPR. Techniques may include anonymization, where identifying information is removed or altered, and encryption to safeguard data during transmission and storage. Effective privacy preservation builds trust with users and helps mitigate legal risks associated with data breaches and misuse of personal information.
