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.

Considerations

The alternative is manual deletion of personal data. This is not feasible in practice. Using the tool takes work off your hands.

Human intervention

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

Risk management

Risk is minimal because it has been chosen that an employee of the municipality always does the final test

Data

personal data, e.g. mail address, address details or signature

Technical design

Smart features, such as set rules or templates, make it possible to anonymise per document or as a bulk. In this way, you can also set the method and degree of anonymisation of commonly used (standard) documents. 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 recognises these and makes suggestions to mask or anonymise them fully automatically
