Responsible use

Goal and impact

The anonymisation software is used to give substance to transparency on the one hand and the necessary protection of the individuals and companies to whom documents relate on the other. The impact of the algorithm on citizens is low. The algorithm specifically searches for (personal) data and confidential company data and masks them regardless of the further content of documents.

Considerations

The use of anonymisation software speeds up and simplifies the process for active and passive disclosure. Automated anonymisation is also less error-prone than human intervention. This reduces the risk of a data breach and better protects citizens' and companies' data.

Human intervention

The documents anonymised by the software can be checked by an employee after completion. The algorithm itself is retrained periodically.
