What is Privacy by Design?

Privacy by Design (PbD) is a framework developed by Ann Cavoukian that calls for privacy to be embedded into the design and operation of IT systems, networked infrastructure, and business practices from the earliest stages. It's now a legal requirement under GDPR.

The Seven Principles

1. Proactive not Reactive Anticipate and prevent privacy-invasive events.

2. Privacy as the Default Automatic protection without user action.

3. Privacy Embedded into Design Built into systems, not bolted on.

4. Full Functionality Positive-sum, not zero-sum trade-offs.

5. End-to-End Security Lifecycle protection of data.

6. Visibility and Transparency Open and accountable practices.

7. Respect for User Privacy User-centric design.
