Goal and impact
The municipality of Sittard-Geleen wants to be transparent to its residents and entrepreneurs, but it also has to comply with privacy legislation. The use of anonymization software makes this possible by supporting employees in anonymizing documents.
Considerations
The use of anonymization software accelerates and simplifies the process of active and passive disclosure. Automated anonymization is also less error-prone than human action. This reduces the chance of a data leak and better protects the data of residents and entrepreneurs.
Human intervention
An employee will review the anonymization software proposal before it is finalized.
Risk management
The risks are minimal, the final decision to anonymize lies with the end user who evaluates the results of the software.
Legal basis
General Data Protection Regulation (GDPR), Implementation Act General Data Protection Regulation (UAVG) and the Open Government Act (Woo)

Elaboration on impact assessments
Before using this anonymization software, a DPIA was used to gain insight into the risks for the data subject and the necessary measures that need to be taken. In addition, it may be the case that certain documents present a potentially high risk if large-scale processing of special categories of personal data has been processed.
Impact assessment
Operations
Data
Depending on the type of document that is anonymized. Think of personal data such as:
Personally Identifiable Information (PII)
- Names
- Addresses
- Dates of birth
- Email addresses
- Phone numbers
- Bank account numbers (IBAN)
- Citizen service numbers (BSN)
- Signatures
Additional words or regular expressions specifically set by the municipality that are considered sensitive can be anonymized.

Technical design
Datamask is a web application with Smart functions, 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.
