Sensitive personal data forms the category of privileged data which is a subject to legal regulation at national and international level with the conceptualization of special qualified personal data. The risks revealed by the rapid transformation of information technologies and the growth of access to information networks are important factors that make sensitive data, special in national and global dimensions in the process of law formation. Special personal data belonging to the sub-category of personal data includes information, which will lead to discrimination or victimization of the individual in the community if disclosed and accessed by others, to high-sensitivity and special features like sexual life and beliefs, political-ideological views, criminal records, biometric and genetic data, race, ethnicity and health information. For this reason, personal safety, fundamental rights, private life, privacy, right to work, democratic participation and protection of social dignity describe areas of legal interest which are considered more important at the level of sensitive data than general personal data.
