Blockchain Application Analysis Based on IoT Data Flow

In the Internet of Things (IoT) system, data leakage can easily occur due to differing security edge devices and different processing methods in transmission process. Blockchain technology has advantages good non-tamperability, decentralization, de-trust, openness, transparency, it protect on Things. This research integrates means by which flow be combined with blockchain prevent privacy throughout entire transportation process from sender receiver. Through a keyword search last five years, 94 related papers Web Science IEEE Xplore were extracted complex frameworks explained using reconstruction graph. The is divided into modules: encryption, access control, expansion, storage, visualization. A total 11 combining IoT summarized. application field was summarized objectively comprehensively, new perspective for studying given.
