Controle de emissão e validação de diplomas digitais utilizando Blockchain

Abstract

With the development of new technologies, new challenges also arise regarding the security of the many information that is constantly generated. This paper aims to evaluate the feasibility of using Blockchain to guarantee security in the issuance of digital diplomas by Higher Education Institutions and to develop an application to exemplify the process of issuing and validating a digital document. For this, a bibliographical research was carried out to understand the operation of a Blockchain network and the level of security presented by it, also sought to understand how the process of issuing a diploma is given and what security mechanisms traditionally used for data protection. Next, a web system was implemented, using modern development tools, in order to demonstrate the issuance of a digital diploma and the use of a local Blockchain network to register this document. The application also allows the validation of documents issued using a multi-level query system, which verifies that the document is registered in the application database and the local Blockchain, only to confirm its authenticity.
