European case law on the processing of personal data

The use of personal data has become one of the most sensitive issues in terms of protection of fundamental freedoms and democratic organisation of the State. This paper will reconstruct the most recent rulings on the subject, which have developed along at least two lines. The first line is aimed at the protection of European citizens' data with respect to processing by companies (both through the censorship of those national systems that do not offer an adequate level of protection, and with respect to companies whose non-EU destination systems do not offer guarantees equivalent to those of the Community system). A second line, on the other hand, is addressed to the protection of the citizen with respect to national instruments of data control for purposes of security and public order. The aim is to analyse the effectiveness of the protection offered by the European Union in this matter in relation to the autonomy profiles, although preserved by the individual member states.
