GDPR Technical Implementation

10. 06. 2024 1 min read intermediate

GDPR is not just a legal document. It requires specific technical measures — encryption, pseudonymization, data portability, right to erasure.

Key Requirements

  • Encryption of personal data (at rest + in transit)
  • Pseudonymization where possible
  • Data minimization — collect only what is necessary
  • Right to erasure — deletion upon request
  • Data portability — export in machine-readable format
  • Breach notification — 72 hours

Implementation

Pseudonymization

import hashlib def pseudonymize(email): return hashlib.sha256(email.encode() + SALT).hexdigest()

Right to erasure

async def delete_user_data(user_id): await db.users.delete(user_id) await db.orders.anonymize(user_id) # Anonymize, not delete await db.logs.redact(user_id) await search_index.delete(user_id) await backups.mark_for_deletion(user_id)

Data export (portability)

async def export_user_data(user_id): data = { “profile”: await db.users.get(user_id), “orders”: await db.orders.list(user_id), “preferences”: await db.prefs.get(user_id), } return json.dumps(data, indent=2)

Key Takeaway

Encrypt, pseudonymize, minimize data. Implement erasure and export APIs. Breach notification within 72 hours.
