Acesso em:.https://bdm.ufpa.br/handle/prefix/8270This research reviewed the protection of sensitive data from the perspective of the General Data Protection Law (LGPD), focusing on cases of data leaks in the Unified Health System (SUS). The methodological approach consisted of a bibliographic review based on scientific articles, institutional reports, and legislation published between 2018 and 2024, accessed in databases such as Scielo and Google Scholar. The studies analyzed discussed failures in the treatment of sensitive information in the SUS, such as the exposure of more than 200 million records in the e-SUS Notifica system in 2020, and the impacts of cyberattacks on outsourced institutions. The theoretical framework was based on the LGPD legislation and information security concepts, in addition to analyses of ethics and privacy in public health. The main results indicate that the leaks occurred due to technological weaknesses, such as the lack of multifactor authentication and the use of obsolete systems, in addition to administrative gaps, such as the absence of effective policies for data management and insufficient training of professionals. The application of the LGPD still faces significant challenges, evidenced by the ineffectiveness of preventive and reactive measures in avoiding new incidents. Consequently, citizen trust in the SUS is shaken, affecting both the collection of accurate data and adherence to health programs. The research concludes that strengthening data governance is essential to reverse this scenario. Measures such as regular audits, adoption of advanced technologies and continuous training of the agents involved are recommended to mitigate risks and ensure the security of information in the SUS. The LGPD has the potential to consolidate an organizational culture focused on data protection, as long as its application is integrated and effective.Acesso AbertoLGPDProteção de DadosVazamentosSaúde PúblicaData ProtectionLeaksPublic HealthCNPQ::CIENCIAS SOCIAIS APLICADAS::DIREITOTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivatives 4.0 International
