QRQueijo: sistema para validação e emissão de identificadores de queijos utilizando Blockchain
(2019-07-12) Silva, Ademário José da; Mendonça, Sérgio Francisco Tavares de Oliveira; http://lattes.cnpq.br/6313698968060384; http://lattes.cnpq.br/3733518574144348
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.
