What does "pseudonymization" achieve in data protection?

Pseudonymization is a process used in data protection that focuses on reducing the risks associated with handling personal data. Specifically, it involves transforming personal data in such a way that the data can no longer be attributed to a specific individual without the use of additional information. This process is crucial because it enhances privacy and security by removing direct identifiers from the data sets, thereby minimizing the likelihood that data can be linked back to individuals.

By effectively masking the identity of individuals, pseudonymization helps organizations mitigate the potential impact of data breaches or unauthorized data access. This is particularly important under regulatory frameworks such as the General Data Protection Regulation (GDPR), which encourages the use of techniques like pseudonymization to protect the privacy of individuals. Additionally, while pseudonymized data still falls under regulatory scrutiny, it allows for a level of analysis and processing that balances the need for data use with the importance of safeguarding personal information.

In the context of data protection practices, this method does not enable increased data collection (which could lead to additional risks) or facilitate data sharing without consent. Moreover, pseudonymization does not imply permanent data storage, as ethical standards and legal requirements for data retention still apply. Thus, the primary goal of pseudonymization is to reduce privacy
