Information about individuals is becoming increasingly valuable. Free data flows across Europe are essential for the common market, but they also pose a significant risk to people's fundamental rights. To safeguard these rights, the General Data Protection Regulation (GDPR) was introduced, a piece of legislation that applies throughout the European Union and, to some extent, globally.This book demonstrates that the GDPR is not incomprehensible and that its principles are, in fact, quite straightforward. It will assist anyone responsible for or involved in the processing of personal data in benefiting from innovative data processing technologies without being unnecessarily hindered by the restrictions of the GDPR. Numerous examples, references to relevant publications from the Data Protection Board (the European supervisory authority), news articles, and case law clarify the law's requirements and make them accessible and clear.Leo's book makes the legal requirements comprehensible and applicable for anyone who utilises personal data for work, in sports clubs and associations, or any other context. Absolutely indispensable.
