| 摘 要: 现有的个人私密信息管理工具一般基于独立的软件或云服务，存在着数据难以共享、易被泄露等问题。 区块链技术具有去中心化、数据难以篡改、可追溯等特点，能用于数据管理，但目前缺乏成熟的应用模式。本文对利用 以太坊智能合约存储和管理数据的特点进行了分析，设计了一个基于区块链技术的个人信息管理系统。其不依赖于任何 服务商实现个人信息数据的存储和分享，能够有效解决数据丢失、数据泄露和数据滥用的问题，同时也为区块链技术应 用于数据管理提供了一种可行的解决方案。 |

| Abstract: The existing personal private information management tools are generally based on independent software or cloud services,and there are problems such as difficulty in sharing data and being easily leaked.Blockchain technology has the characteristics of decentralization,falsified data prevention,and traceability.It can be used for data management,but currently there is no mature application mode.We analyze the characteristics of using Ethereum smart contracts to store and manage data,and design a block-chain-based personal information management system.It does not rely on any service provider to store and share personal information,and can effectively solve the issues of data loss,data leakage,and data abuse. Furthermore,it provides a feasible solution for blockchain technology applied to data management. |
