This study aims at analyzing how fundamental rights and individual freedom interfere with privacy issues for transgender people. The main purpose is to identify the legal and social challenges faced by this community in the process of legal recognition of gender identity. To achieve these objectives, the research uses a mixed methodology, which combines comparative legal analysis of legislation from different jurisdictions with relevant jurisprudence and public policy, highlighting exemplary practices and legislative gaps. The results of the study indicate the existence of a gap between the principles of human rights agreed at the international level and their implementation at the national level. Despite significant progress in some countries, many transgender individuals still face bureaucratic obstacles and discrimination when claiming their rights. Therefore, is obvious the need for legislative reform to facilitate the recognition of gender identity in a way that respects personal autonomy and privacy. The study recommends the development of policies and practices that promote social integration and respect for human rights for transgender people, emphasizing the crucial role of a rights-based approach in achieving equality and non-discrimination.
