[jjyuhub]

The current implementation of lacks safeguards required by Article 9 of the GDPR regarding the processing of special categories of personal data. The code currently allows processing of any data columns without screening for sensitive personal data categories.

Current Behavior: The anonymization process accepts any feature names as quasi-identifiers
No validation exists to detect or prevent processing of special category data
No mechanisms to screen for proxy variables that might reveal protected characteristics
Categorical feature processing occurs without sensitivity checks

Racial or ethnic origin
Political opinions
Religious or philosophical beliefs
Trade union membership
Genetic data

Health data
Data concerning a person's sex life or sexual orientation

Impact:
Risk of non-compliance with GDPR Article 9

Legal exposure for organizations using this code
Privacy risks for data subjects
