QRQueijo: sistema para validação e emissão de identificadores de queijos utilizando Blockchain

Abstract

The food chain in the food industry has generated more and more information about its processes. Ensuring the integrity and security of this information has been a challenge. The current work aims to understand and evaluate what kind of information is generated in these processes, as well as from the results obtained, implement a solution that can generate identifiers for cheeses and through a local Blockchain network validate this information, as well as from a mobile application it is possible to view this data. For this, it was necessary to understand the structure of Blockchain and its characteristics in relation to information security through a bibliographic search. Important points of traceability have been identified for food production processes. With the results it was possible to model and implement a web system capable of recording data about a cheese and its manufacturer in a local Blockchain network, validating the information provided and made available to its consumers through the QRQuejio (Android) application, in which the cheese was transported. And, using a multi-level query system, check the authenticity of the records by reading the system database and the local Blockchain to confirm the authenticity of the record.
