Personal Data Protection Aspects of Big Data

Paolo Balboni

Abstract

New technologies have significantly changed both the way that we live and the ways in which we do business. The advent of the Internet and the vast amounts of data disseminated across global networks and databases has brought with it both significant advantages in terms of scientific understanding and business opportunities, and challenges in terms of competition and privacy concerns. More data are currently available than ever before. Neelie Kroes, vice president of the European Commission responsible for the Digital Agenda, defined our era as “the data gold rush.” What is Big Data? In its most general sense, the term Big Data refers to large digital data sets often ...
