The General Data Protection Regulation (GDPR) gives extra protection to certain types of sensitive personal information. These are known as special categories of personal data under Article 9 GDPR.
Organizations that collect or process this data must follow stricter rules because misuse can create higher risks for individuals’ privacy, rights, and freedoms.
What Are Special Categories of Personal Data?
Under GDPR, special category data includes personal data revealing or concerning:
- Racial or ethnic origin
- Political opinions
- Religious or philosophical beliefs
- Trade union membership
- Genetic data
- Biometric data used for identification
- Health data
- Sex life data
- Sexual orientation
Why This Data Needs Extra Protection
This information is considered highly sensitive. If mishandled, it may lead to discrimination, identity misuse, reputational harm, or privacy violations.
That is why GDPR generally restricts processing of this data unless a valid legal condition applies.
When Can Organizations Process Special Category Data?
Processing may be allowed when one of the Article 9 conditions applies, such as:
- Explicit consent from the individual
- Employment or social security obligations
- Protecting vital interests
- Healthcare or medical purposes
- Legal claims
- Substantial public interest
- Scientific or statistical research under safeguards
Examples of Special Category Data
Examples include:
- Employee medical records
- Fingerprint access systems
- Diversity or ethnicity data
- Religious accommodation requests
- Health insurance information
- Biometric identity verification
Best Practices for Compliance
Organizations handling special category data should:
- Minimize data collection
- Use strong security controls
- Limit access to authorized users
- Maintain clear retention policies
- Document lawful basis for processing
- Conduct DPIAs when high risk exists
- Update privacy notices regularly
