What is Personal Data breach

The digital infrastructure of smart cities necessarily implies collecting big amounts of personal and its subsequent processing by software and applications designed to acquire analytical capabilities regarded to public spaces in order to enable efficient control over it. In the European Union legal context, aiming to densify the principle of informational self-determination, the general data protection regulation (GDPR) has provided citizens with greater power and control over their personal data, turning the responsibilities of smart cities administrators towards citizens much heavier. This chapter aims to analyse the impact on personal data and democratic public spaces derived from smart cities activities, to present the rights granted to individuals by the GDPR and its applicability to smart cities, and to make some recommendations regarding the implementation and the adaptation of the Regulation to the specific case of a smart city, not only to preserve a high-level level of privacy protection but also as a means to promote democratic solutions in public spaces.
