Key insights: Implementing GDPR Technically
Implement GDPR technically: encryption, access control, retention and deletion patterns that auditors and engineering can both defend.
Implementing the GDPR technically: TOMs under Art. 32
Data protection is not only a legal but a technical task. Art. 32 GDPR requires technical and organisational measures (TOMs) appropriate to the risk. We translate these requirements into concrete software and infrastructure decisions – measurable and verifiable – as part of GDPR-compliant software development. We do not replace legal advice; the binding interpretation stays with your data protection counsel.
Encryption in transit and at rest
We protect personal data with TLS in transit and strong encryption at rest (e.g. AES-256), backed by secure key management. This reduces the impact of data breaches and is a recognised state-of-the-art measure.
Access control and permission concepts
Role-based access, the principle of least privilege and clean authorisation at object level (see API security) ensure that only authorised people and systems reach personal data – consistent with Security by Design.
Deletion concepts and data minimisation
Storage limitation requires data to be deleted or anonymised once the purpose ends. We implement retention periods, automated deletion routines and data minimisation – so that only what is genuinely needed is collected and stored.
Logging, accountability and privacy by design (Art. 25)
Logging must be sufficient for accountability without over-collecting personal data. Privacy by design and by default (Art. 25 GDPR) means privacy-friendly defaults from the start – an approach that also strengthens overall IT security and reduces the attack surface tested in a security audit.
Frequently asked questions about Implementing GDPR Technically
- What are technical and organisational measures (TOMs)?
- TOMs under Art. 32 GDPR are concrete safeguards for personal data – e.g. encryption, access control, pseudonymisation, logging and recovery procedures. They must match the protection needs and be documented in a verifiable way.
- What encryption does the GDPR require?
- The GDPR names no specific technology but requires the state of the art. In practice that means TLS for transport and encryption of sensitive data at rest (e.g. AES-256), complemented by secure key management.
- Do we need a deletion concept?
- Yes. The principle of storage limitation means data is deleted or anonymised once the purpose no longer applies. We implement retention periods and automated deletion routines technically and document them.
- What is the difference between pseudonymisation and anonymisation?
- Pseudonymised data can be re-linked to a person with additional knowledge and remains personal data. Anonymised data allows no re-identification and falls outside the GDPR – but the anonymisation must be robust.
- Who is liable with a processor (DPA)?
- Controller and processor carry graded obligations. A data processing agreement governs instructions, TOMs and sub-processors. As a development partner we support the technical implementation of the agreed measures.
