Confidentiality and integrity in GDPR
Confidentiality and integrity are core data protection principles under the General Data Protection Regulation (GDPR). These principles ensure that personal data is processed securely, protecting it from unauthorized access, unlawful processing, accidental loss, destruction, or damage.
As part of GDPR’s seven key principles, confidentiality and integrity require organizations to implement technical and organizational security measures to safeguard personal data throughout its lifecycle.
What do confidentiality and integrity mean under GDPR?
Under Article 5(1)(f) of GDPR, organizations must process personal data in a way that ensures:
- Confidentiality – Data is protected from unauthorized access, ensuring only authorized individuals can view or process it.
- Integrity – Data remains accurate, complete, and unaltered throughout its storage and processing.
These principles are essential for maintaining data security, reducing breach risks, and ensuring compliance with privacy regulations.
Key aspects of confidentiality & integrity
