vertrouwelijkheidsbelang

Vertrouwelijkheid, or confidentiality, is the obligation to protect information from unauthorized access or disclosure. It encompasses the secure handling, storage, and use of data or communications entrusted to an individual or organization. The term derives from the Dutch word vertrouwen (trust) and denotes information treated as secret or restricted to a limited audience. In practice, confidentiality obliges professionals and institutions to restrict who can access information, why they can access it, and for how long it can be kept.

Confidentiality is distinct from privacy; privacy concerns individuals’ rights over their personal information, while confidentiality relates to how information is handled within trusted relationships or systems. It is a central requirement across many sectors—healthcare, legal services, finance, journalism, and government—where divulging information could harm clients, patients, or partners.

Legal frameworks: In the European Union and the Netherlands, the General Data Protection Regulation (GDPR/AVG) mandates safeguards to protect personal data, including confidentiality measures. Sector-specific rules impose additional duties (for example, medical confidentiality and attorney–client privilege). Breaches can lead to civil liability, regulatory penalties, or professional discipline, as well as reputational damage.

Practices and safeguards: Organizations implement access controls, encryption, secure storage, data handling policies, training, and incident response. Non-disclosure agreements and contractual clauses formalize duties toward third parties. Confidentiality is not absolute; disclosures may be required by law, to protect vital interests, or with proper authorization.
