Anonymisation in data privacy refers to the process of transforming personal data in such a way that the individual cannot be identified. This process often involves removing or altering personal identifiers like names, addresses, and other unique elements. However, true anonymisation is challenging, as it requires ensuring that individuals cannot be re-identified, even indirectly. The effectiveness of anonymisation techniques is crucial in legal contexts, where data protection regulations may allow freer use of anonymised data. The evolving nature of technology and data analysis methods continually tests the limits of anonymisation, making it a dynamic and complex aspect of data privacy.
