【摘要】 随着社会信息化程度的加深，数据的安全性正在被人们愈来愈明显的重视。硬盘作为大多数计算机设备的数据存储介质，对于它的数据保护就显得异常重要。目前国内外对此的工作一般是对数据进行加密，而对于介质本身丢失或被盗窃缺乏比较全面的解决方案。本文的目的在于设计实现一个软硬结合的保护机制，通过GPS技术定位硬盘介质当前位置，使用传感器来检测硬盘周围温度，支持用户使用短信方式与该硬盘保护系统进行交互，并能对使用系统的用户和用户操作进行安全验证，根据硬件的状态自动向管理员报警、甚至自动销毁数据，使之能最大限度保护硬盘，避免其中的数据被非法获取，采用了伪装盘和实用盘结合的机制，即保证了用户数据的安全性，也可以防止误操作造成数据的丢失。本人的主要工作是：（1）完成了开源系统软件μC/OS-II的分析和移植；（2）设计和实现特定硬件模块的驱动程序；（3）在分析GSM网络的短信通信机制基础上，根据需要对短信进行编码和解码；（4）完成安全控制模块的设计实现，该模块功能是接收和执行用户的指令、自动根据环境状态报警、自动在特殊状况下销毁数据，以及向用户通知等。本论文设计实现的硬盘安全保护机制在东莞市公安局技术侦察支队蓝盾系统中进行了部署，实际的使用情况表明其在保护硬盘的数据安全性上具有良好的效果。更多还原

【Abstract】 As social informatization deepens, people pay more and more attentions to the safety ofdata. Hard-Disk is data storage medium for most computers, due to which it is extremelyimportant to protect its data. At present, data encryption is a common measure taken homeand abroad, whereas there is a lack of a comprehensive solution to protect the medium fromloss or burglary.The purpose of this article is to designing a protection mechanism for hard, which candetermines the current position of hardware by GPS, detects the ambient temperature of harddisk by a sensor, supports users to interact by messages and the hard disk protection system,verifies the safety of users who use the system and their operation, automatically gives analarm to the administrator according to the state of hard disk and even automatically destroysthe data, in order that the hard disk can be protected as far as possible and the its data can beprevented from illegal acquisition. The system is equipped with fake hard disk in addition topractical hard disk, which not only guarantees the safety of users’data, but also avoids dataloss resulted from faulty operation.My prime tasks are as follows:（1）analyzing and transplanting the open-source software;（2）designing drivers for specific hardware;（3）encoding and decoding messages according to needs after analyzing messagingmechanism of GSM network;（4）designing a safety control module which can receive and execute users’instructions,give automatic warnings according to environmental conditions, automaticallydestroy data under special situation and notify users, etc.The hard disk storage protection mechanism designed by the author has been deployed inthe Blue Shield of the technical reconnaissance detachment, Dongguan Public SecurityBureau. After practical use, it is suggested that this mechanism is effective in protecting thedata safety of the hardware.更多还原
