Verificação de autenticidade de contas de órgãos públicos em mídias sociais com blockchain: uma abordagem para transparência e confiabilidade

Abstract

With the growing presence of public agencies on social media, the risks related to the dissemination of false information by unofficial profiles increase. This work proposes the development of a web system that uses blockchain technology to guarantee the authenticity of institutional profiles, linking them in an auditable manner to their respective public agencies. The application was built with the Hyperledger Fabric platform and offers features such as registering institutions, linking and revoking profiles, and public consultation to verify these links. To assess the system’s acceptance, a user study was conducted, based on the TAM (Technology Acceptance Model). The results indicated that 86.6% of participants fully or partially agree that the system is useful to avoid deception caused by fake profiles and would use it regularly. Most users demonstrated ease in using the application, even with little prior knowledge of blockchain. Thus, the solution proved to be effective in promoting greater trust and transparency in digital communication between public agencies and society.
