Privacy by Design is not just a GDPR requirement — it is a competitive advantage. Learn the seven foundational principles and how to apply them in practice.
What is Privacy by Design?
Privacy by Design (PbD) is an approach to systems engineering that takes privacy into account throughout the whole engineering process. Developed by Dr. Ann Cavoukian, it has been codified into law through Article 25 of the GDPR, which requires data protection by design and by default.
The Seven Foundational Principles
1. Proactive, Not Reactive
Anticipate and prevent privacy-invasive events before they happen. Do not wait for a breach or a regulatory investigation to address privacy risks.
2. Privacy as the Default Setting
Personal data should be automatically protected in any given IT system or business practice. No action should be required on the part of the individual to protect their privacy.
3. Privacy Embedded into Design
Privacy is not bolted on as an add-on after the fact; it is embedded into the design and architecture of IT systems and business practices.
4. Full Functionality — Positive-Sum
Privacy by Design seeks to accommodate all legitimate interests and objectives in a positive-sum manner, not through a dated, zero-sum approach where unnecessary trade-offs are made.
5. End-to-End Security
Privacy by Design extends throughout the entire lifecycle of the data involved, from collection to secure destruction.
6. Visibility and Transparency
All stakeholders can verify that the business practices and technologies involved operate according to the stated promises and objectives.
7. Respect for User Privacy
Above all, Privacy by Design requires architects and operators to keep it user-centric.
Practical Application
Embedding Privacy by Design into your organisation requires a Data Protection Impact Assessment (DPIA) process for new projects, privacy review gates in your software development lifecycle, and a culture where privacy is considered a quality attribute alongside performance and security.
