For software companies that need to comply with Brazil’s General Data Protection Law (LGPD), data breaches not only might harm application users but also could expose the companies to hefty fines. In this context, engineering fine-grained authorization controls (that comply with the LGPD) to decentralized web application requires creating audit trails, possibly in the source code. Although the literature offers some solutions, they are scattered. We present Esfinge Guardian, an authorization framework that completely separates authorization from other concerns, which increases compliance with the LGPD. We conclude the work with a brief discussion.InglêsCC BYArtigos CientíficosEngenharia de softwareLei Geral de Proteção de Dados (LGPD)https://doi.org/10.1145/3308560.33164612019819-822May
