This thesis intends to contribute for a better understanding and application of the so-called right to be forgotten in the contemporary society, notably characterized by the intense circulation of information made possible by the ongoing technological progress. In order to develop the study, it was necessary to weave critical considerations to the term used in Brazil to identify the right under review, conceptualize it as a way to restrict the unlimited disclosure of past individual information lacking public interest, as well as define its legal configuration of fundamental right of the personality resulting from the general clause of human dignity protection. From the recognition of clear limits for the application of the right to be forgotten and considering the protection of the private life in its current bias of control over the circulation of information regarding individuals, it is noticeable that it is not only possible but also fundamental to provide for the full protection of the right addressed in the thesis. Due to the magnitude of the role that is currently performed by the Internet in social communication, the right of an individual to require the exclusion of results from the lists of links presented after a search in search providers using certain words or terms, even if such exclusion fails to also reach the source where the information was originally disclosed, is defended, among other possibilities to apply the right to be forgotten. In addition to that, the analysis of the legislation related to the subject, the assessment of draft bills on the subject, as well as the survey of the recent Brazilian jurisprudence in the application of the right to be forgotten were methods used to get to the suggestion of criteria that may be adopted when pondering the possibly conflicting interests with freedom of expression and protection of personality rights. In short, outdated and irrelevant information under the perspective of public interest, whose dissemination may cause proven and unfair damages to the rights of personality, shall not beunrestrictedly disclosed, under the penalty of configuring notorious violation to human dignity and, moreover, not allowing that defended informative limitation to be considered a practice that is similar to the so condemnable censorship.
