The EU Data Retention Directive (2006/24/EC) provides an obligation for providers of publicly available electronic communications services and of public communications networks to retain traffic and location data for six months up to two years for the purpose of the investigation, detection, and prosecution of serious crime. Considering potential uses and misuses of retained data such as traffic analysis, social network analysis, and data mining, this research examines the suitability, necessity, and proportionality of the interference with the fundamental rights to privacy and data protection as guaranteed by the Charter of Fundamental Rights of the European Union.
