Responsible use

Goal and impact

The anonymization software is used to provide transparency on the one hand and the necessary protection of the persons and companies to whom documents relate on the other.

Considerations

The alternative is to manually erase personal data. In practice, this is not possible. Using the tool takes work off your hands.

Human intervention

The documents anonymized by the software can be checked by an employee afterwards. The algorithm itself is retrained periodically

Risk management

The risk is minimal because it has been decided that a municipal employee always carries out the final test.

Data

personal data, such as email address, address details or signature

Technical design

Smart features, such as set rules or templates, make it possible to anonymize per document or in bulk. In this way, the method and degree of anonymization of frequently used (standard) documents can also be set. The software then uses pattern recognition and Natural Language Processing to search for names, addresses, dates of birth, specific set words, signatures or regular expressions (such as e-mail, IBAN, BSN). The DataMask software recognizes these and makes suggestions to mask them or anonymizes them completely automatically
