Reidentifikációra

Reidentifikációra is a Hungarian term that translates to "re-identification" in English. It refers to the process of identifying an individual who was previously de-identified or anonymized. This can occur when seemingly anonymous data is linked with other available information, allowing for the reconstruction of a person's identity.

The concept of re-identification is particularly relevant in the context of data privacy and the use of personal information. While data anonymization techniques aim to protect individuals' privacy by removing direct identifiers, they are not always foolproof. Re-identification can happen if the de-identified dataset is combined with external sources of information, such as public records, social media profiles, or other datasets, which contain the missing pieces needed to link back to the original individual.

The ability to re-identify individuals raises significant privacy concerns. It can expose sensitive personal details that individuals believed were protected. This is a key challenge in fields like data mining, research, and the development of artificial intelligence, where large datasets are often used. Regulations such as the General Data Protection Regulation (GDPR) in Europe address re-identification by stating that data that can be re-identified is still considered personal data, requiring appropriate safeguards. Therefore, robust de-identification methods and careful consideration of data linkage risks are crucial to maintain privacy in the digital age.
