Título.https://repositorio.ifal.edu.br/handle/123456789/1415Information security is an essential aspect for the reliability of systems that handle data, with integrity, authenticity, and availability of information as its pillars. In the context of educational institutions, these principles become even more relevant, since academic documents have institutional, academic, and legal value. The absence of standardized mechanisms for managing and verifying these documents can make them vulnerable to loss, alteration, and fraud. Given this scenario, this work proposes the development of a system for managing the thesis defense process for the Federal Institute of Alagoas (IFAL), using blockchain technology as an anti-fraud mechanism, based on permissioned blockchain with Hyperledger Fabric, integrated with a distributed storage system (IPFS), in which academic documents are securely stored, while only their identifiers and integrity proofs are recorded on the blockchain. The system includes functionalities such as scheduling defenses, document submission and versioning, approval workflow between students, advisors, and coordinators, as well as document authenticity verification. To validate the proposal, a functional prototype was developed with a web interface and API integrated into the blockchain network, allowing for the simulation of its application in an academic context. The results obtained demonstrate that the solution contributes to increasing the reliability, traceability, and transparency of academic records.ptAttribution-NonCommercial-NoDerivs 3.0 BrazilBlockchain permissionadaHyperledger fabricArmazenamento distribuídoIntegridade documentalInformática na educaçãoTrabalho de Conclusão de CursoCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::METODOLOGIA E TECNICAS DA COMPUTACAO::SISTEMAS DE INFORMACAO
