Research on Information Security and Privacy Technology Based on Blockchain

Blockchain provides IoT security and privacy in all industries including manufacturing, finance, healthcare, supply chain, e-governance, education, banking, trading through decentralization, persistency, anonymity, auditability characteristics. This paper presents the blockchain technology assimilating with other data technologies to design a based sharing system. Based on network architecture of system, we test analyze various processes sharing. To function have built environment system consisting three nodes, four participant nodes (three users, one provider), data-sharing composed CA. We developed Base App as an application provided by user, addition, deletion, check modification code for simulated experiment related scenario, then wrote program generate vehicle information import it into MySQL storage. The has found some valuable results functional test, safety performance realizes possibility that can connect multiple participants their corresponding data.
