ABSTRACT
This chapter discusses the data protection and security in electronic communications. It has been an evolutionary concept: starting with the electronic age, where personal computer began to be used; followed by information age, characterized by networked computers. However, there are important elements of the earlier modernity such as the historical moment in which human rights were recognized that persist into the digital society. In the digital world, the person is the result of the aggregation of different data and therefore can have many different electronic personalities created in a heterogeneous way by simple technological performance or by commercial interest. The exposure of privacy increases because defence and public security interests are becoming more important. The sophistication of the means of attack and disclosure of personal information increases simultaneously with the development of security systems and protection technologies.
