O uso de blockchain para auditoria de dados: um estudo de caso em cloud computing

Abstract

This work explores the applications of Blockchain technology within Cloud Computing context. The research started with a literature review, contextualizing the main concepts and characteristics involving Cloud Computing and Blockchain technology, in addition to bring related works to this integration, that served as a starting point for the idealization of this monograph. During the study, the main challenges faced by Cloud systems were identified, such as security issues involving data violation, unauthorized access and permanent data loss. Moreover, it was possible to trace which Blockchain characteristics could meet this demand, such as the authorization levels defined for each user and a ledger containing all data history. The results showed that Blockchain technology is indeed relevant in the Cloud context, and can be useful as a means of audit in cases of cloud mistrust, ensuring that customers and users have access to a complete and immutable record of all data inclusions and changes. Therefore, it is expected that this work can contribute to future studies and developments related to the integration of these two emerging technologies, bringing the interest of professionals in the area.
