The evolution of information and communications technology, and particularly the Internet of Things as the basis for the setting up of the Smart Cities, are provoking a worldwide revolution in terms of data protection management. A clear example of this shift can be seen in the European Union which is adapting the regulation to meet current society requirements, although similar initiatives are being undertaken by the rest of continents. However, existing data regulation and management solutions offer isolated tools that cover particular rights and laws and are actually not conceived to be integrated with libraries widely used by organizations to implement data management processes. To cover the previous gap, we propose a novel platform which is geared toward the protection of citizen’s sensitive data according to their data protection preferences and the rights provided by current data protection regulation laws. Finally, we present a case study to demonstrate how our platform manages data anonymization, protecting a private citizen’s right.
