💡Quick Answer

Design and implement a pseudonymization architecture: token vault for identity mapping, separated behavioral data store, and pseudonym lifecycle management. GDPR Article 25 and Recital 26 compliant. Enables analytics without exposing real identities. Fixed price €2,700–5,400.

📋Why this service exists

Article 32(1)(a) explicitly names pseudonymization as an appropriate security measure. Article 25 (Privacy by Design) requires it by default where possible. Recital 26 clarifies that properly pseudonymized data reduces GDPR exposure significantly — pseudonymized data that cannot be re-identified without the key is not considered personal data.

Frequently asked questions

What's the difference between pseudonymization and anonymization?
Pseudonymized data can be re-identified using a key — it's still personal data under GDPR but with reduced risk. Truly anonymized data (irreversibly de-identified) is no longer personal data. Pseudonymization is used when you need to re-identify for legitimate purposes (customer support, fraud investigation).
Does this let us skip GDPR requirements?
No — pseudonymized data is still personal data. But it significantly reduces your risk profile and demonstrates proactive compliance (Article 25). It also limits breach damage: if behavioral data is stolen but the token vault is not, identities remain protected.
