Responsible use

Goal and impact

We use a tool to mask personal data. We do this when making decisions available for inspection and when requesting documents for, for example, objections, Woo requests and other information requests.
Impact is low: The algorithm searches specifically for personal data and masks it regardless of the further content of documents.

Considerations

This tool helps us recognise and quickly (and digitally) mask personal data.

Human intervention

Any masked text in a document is approved or rejected by an employee.

Risk management

Low

Legal basis

Environmental Law (General Provisions) Act (Wabo)
Open Government Act (WOO)
General Administrative Law Act (Abw)

Operations

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.
