Every company, large or small, that handles personal data concerning individuals within the European Union, is obliged to fully comply with the new EU GDPR (EU General Data Protection Regulation), by reviewing or even revising all its information management procedures. This represents the biggest change in data protection legislation in the last 20 years. All companies must consider adapting or even changing their information systems to comply with the terms of the new Regulation.  The GDPR aims to expand data protection in the era of big data and cloud computing, ensuring that it constitutes a fundamental basic right and therefore authorizes the respective Data Protection Authorities  to impose severe fines. In this book, written by the most specialized team of E&Y led by Eirinikos Platis,  you will find all the essential information that every executive, owner, or business manager, from the smallest to the largest, needs to know about the new Regulation, gathered and well-organized. The series  SMALL INTRODUCTIONS   includes reference books, written by experts, which provide authoritative and in-depth information on topics of immediate interest. Simple but not simplistic, scientific but not inaccessible, concise but complete, the series offers the modern reader the keys to deeply understand our complex and changing world. The director of the series is  Babis Papadimitriou.
