Preface

Welcome to the wonderful world of data privacy! You might have some preconceived notions around privacy—that it is a nuisance, that it is administrative and therefore boring, or that it’s a topic that interests only lawyers. What this book will show you is just how technically challenging and interesting data privacy problems are and will continue to be for years to come. If you entered the field of data science because you liked challenging mathematical and statistical problems, you will love exploring data privacy in data science. The topics you’ll learn in this book will expand your understanding of probability theory, modeling, and even cryptography.

Learning how to solve data privacy problems is increasingly critical for data science practitioners today. You’ll be able to solve real-world problems in fields like cybersecurity, healthcare, and finance, and you’ll be able to advance your career in a patchwork world of privacy regulations, policies, and frameworks. Since 2018 when the General Data Protection Regulation (GDPR) went into effect in Europe, the global landscape has become more complicated, and that complexity will increase as regulatory agencies and lawmakers continue to change the rules about how, where, why, and when you store data. Building up your data privacy and data security skill set now is an investment in your career.

Additionally, taking the time to learn new privacy skills means you are contributing to the field of data science—enhancing trust, ...
