Data Anonymization

The protection of personal data is one of the priority topics of the European Union, including Hungary, and since the entry into force of the GDPR in 2016, companies must pay special attention to its implementation and compliance. Data protection should be ensured in both live and test systems against unauthorized access and use, in particular by anonymisation and pseudonymisation. Anonymization is an undecryptable transformation of data, while pseudonymisation means a modification that can be decrypted with a secret key. In developing our service, we follow the recommendations of the European Commission Opinion 05/2014 and maintain technical consistency, ensuring legal and technical compliance through multi-level processing and continuous monitoring.

The first step to anonymization is to create a Personal Data Map (PDM), which maps the personal data stored in company systems and their relationships. This map serves as the basis for GDPR compliance and data security. Using PDM, anonymization interfaces can be designed, and then iteratively running the procedure ensures data consistency. By the end of the process, the systems will become fully GDPR compliant and a robust data protection framework that is sustainable over the long term will be established.
