The present dissertation intends to realize an investigation about the social phenomenon of individual and collective political actions conducted anonymously from the perspective of the right to privacy, especially because of the prohibitive trend adopted by Brazilian s institutional agents, in the opportunities they have spoken on the subject. In this sense, we develop a theoretical and prescriptive research, using the hypothetical-deductive method. Our main objective is the analytic construction of certain concepts related to democratic political participation today, to the anonymity and to privacy. It is intended, therefore, to identify and propose some regulatory principles of the exercise of anonymous political action, according to limits exploited in the development of the research. The construction of these regulatory principles, in turn, was made from two major conceptual perspectives. First, we used the concept of Michael Hardt and Antonio Negri about Multitude (2005) , the political entity responsible for guiding the current political actions, as well the description of events in network made by Manuel Castells (2013) . With regard to the contours currently assumed by the right to privacy and its relation to the anonymity of political actions, we used the privacy notion developed by Stefano Rodotà (2007, 2011). From these two main theoretical axes, we found that, in the various forms of contemporary political activity, mainly influenced by the communication paradigm of digital technologies, anonymity, as an essential feature of communication and expression in several cases, has already social benefits that should be considered in any regulatory proposal on the subject.
