ABSTRACT
The most important aim of security is to ensure full and free enjoyment of fundamental rights without fear that something like a terrorist attack or crime can impede it and deprive. This chapter analyses existing interrelations and balance between security and fundamental rights, and freedoms in general, and to look in depth at rights directly related to information exchange in police investigation, i.e. privacy and data protection. While gathering and further processing of information, among all fundamental rights, the right to privacy has the biggest risk of violation. Protection of privacy was directly established by the Directive 2002/58/EC of the European Parliament and of the Council of July 12, 2002 concerning the processing of personal data and the protection of privacy in the electronic communications sector. The principle of data accuracy is broadened and includes the obligation to make distinctions between personal data based on facts and based on personal assessments.
