BITTRUST - Solução de Prova de Autenticidade Utilizando o Blockchain

This paper highlights alternative solutions for blockchain technology that address the principles of Information Security and apply these concepts to the registration and validation of digital documents on the Bitcoin network. This way documents can be validated and publicly visible to any user with Internet access. The goal is to develop a solution that aims to abstract all the complexity of cryptographic algorithms and techniques and use them in conjunction with blockchain technology, enhancing the registration and authenticity of a digital document in a decentralized public environment. With the developed solution it is possible to register digital documents in the Bitcoin blockchain, ensuring the authenticity validation of digital files in a chronological and cryptographic manner. In this way the tool can guarantee the authenticity of files without the need for a certifying entity to guarantee its legitimacy.
