Part I provides the building blocks for understanding GDPR. In this section, we discuss why data privacy has become a pressing global concern and introduce the fundamental concepts and definitions used in the GDPR. We will cover the seven key principles that underpin the regulation, define its scope of application, clarify the roles and responsibilities of dataΒ controllersΒ andΒ processors, and explain what constitutes personal data (and sensitive personal data). By the end of Part I, youβll have a solid grounding in the βlanguageβ of GDPR and the rationale behind it, which will prepare you for the more detailed topics that follow.
