| 中文摘要:为解决传统烟草行业缺少物料管理数据留痕导致的物料无法追溯问题，在研究区块链中智能合约及IoT技术基础上提出了一种基于物联网及区块链的去中心化数据管理系统。系统由三个主要组件组成，包括IoT客户端网络、智能合约和安全模块。实现利用区块链技术防止数据信息被篡改，利用数据加密等特性存储数据。通过物联网技术实现物料从采购到出库全生命周期数据可查询，可溯源，可分析，可信任。仿真分析结果进一步验证了所提方法的有效性及实用性。 |

| Abstract:In order to improve the traditional tobacco industry’s lack of material management data traces, which leads to the problem that materials can not be traced back, this paper proposes a decentralized data management system based on the Internet of things and blockchain, based on the research of intelligent contract and IoT technology in blockchain. The system is composed of three main components, including IoT client network, smart contract and security module. It can store data by using blockchain technology to prevent data tampering, data encryption and other features. It can query, trace, analyze and trust the whole life cycle data of materials from purchase to delivery through internet of things technology. The simulation results further verify the effectiveness and practicability of the proposed method. |
