一种基于区块链的个人数据保护模型

An individual Data Protection Model Based on Block Chain

近年来因监听和安全漏洞导致用户数据泄露的事件时有发生,这使得人们开始怀疑现有的第三方机构大量收集和控制个人隐私数据的行为是否会威胁到其信息安全。然而在金融领域,比特币向世人展示了使用"以公账为基础的分散对等网络",完全可以创建出一种受信的、可审计的机制。因此本文通过介绍一种采用"分散式"技术的个人数据管理系统的简要模型,来展示如何使用区块链技术保护个人隐私数据。这个模型实现了一系列将区块链技术转化为一种"去中心化的自动权限控制管理机制"。与比特币交易系统不同的是,这个模型节点间"交易"的不全是虚拟货币,更多的是用于携带存储、查询、分享数据的信息。本文最后还讨论了未来将区块链技术全面拓展成可信计算的可行方案。

In recent years,the leakage of user data due to surveillance and security loopholes has occurred,which has led people to doubt whether the existing third-party agencies'extensive collection and control of personal privacy data will threaten their information security.In finance,however,Bitcoin shows the world that using"decentralized peer-to-peer networks based on public accounts"can create a credible and auditable mechanism.Therefore,this paper introduces a brief model of personal data management system using"decentralized"technology to show how to use block chain technology to protect personal privacy data.This model implements a series of changes in block chain technology to a"decentralized automatic permission control management mechanism."Unlike Bitcoin trading systems,not all"transactions"between this model node are virtual currencies,and more are used to carry information that stores,queries,and shares data.Finally,the paper discusses the feasible scheme of extending the block chain technology into credible computing in the future.
