Medical data protection in hair clinics
Health data is a special category under GDPR. If your clinic processes patient data, you need to meet specific requirements.
What is health data (Art. 9 GDPR)
Article 9 of the GDPR defines "special categories of data" as those relating to a person's health. This includes:
- Patient medical history
- Clinical photos (pre and post-operative)
- Analysis results and diagnoses
- Alopecia classification (Norwood/Ludwig)
- Treatment and medication information
- Biometric data (3D scalp scans)
Encryption and access control for clinical data
Legal bases for processing medical data
To process health data, you need a reinforced legal basis:
- Explicit consent (Art. 9.2.a): the patient signs specific consent for health data processing
- Medical necessity (Art. 9.2.h): processing is necessary for diagnosis, medical treatment, or health management
- Vital interest (Art. 9.2.c): in medical emergencies
What your clinic MUST do
Specific informed consent
- Separate document from medical treatment consent
- Explain what data is collected, for what purpose, for how long
- Inform the right to withdraw consent
- Must be signed before collecting any data
Record of processing activities
- Mandatory document detailing all data processing
- Include: purpose, data categories, recipients, retention periods
Data Protection Impact Assessment (DPIA)
- Mandatory when processing health data at large scale
- Analyzes risks and mitigation measures
Security measures
- Data encryption in transit (TLS 1.3) and at rest (AES-256)
- Role-based access control (RBAC)
- Access logging (audit log)
- Encrypted backups
- Breach response plan (72 hours to notify the authority)
