基于Andriod系统手机私人数据保护软件控制平台

摘要

随着信息时代的到来，人们在享受其带来的极大便利和利益的同时，也面临着信息安全的严峻考验，特别是在三年前的“棱镜门”事件曝光以来，公众对信息安全的重视提到了前所未有的高度，人们对保护自己私人数据的意愿也十分迫切。另一方面，随着传统互联网的进一步普及和新兴移动互联网的繁荣，人们各类社交账号、银行账号等信息也越来越多。记忆和管理数量庞大的账号密码便成了人们的巨大负担。因此设计和开发一款安全、高效的软件来帮助用户管理各种账户和密码变得十分迫切和必要。

本文主要介绍上述软件的设计开发过程和相关的开发知识。本系统是一款专注于私人数据保护的Android应用程序它作为安全类软件，有强大的数据安全保障机制。系统采用了AES加密算法作为程序数据加密算法，AES算法具有更高安全性、效率和灵活性，能够抵御已知的所有攻击方式。同时系统还具有登陆密码验证、数据加密秘钥验证、用户数据跨设备不可使用、非安全状态销毁数据、程序后台驻留控制等多种措施以保障用户数据安全。本系统在Windows系统环境下，使用SDK

4.4、SQLite、Eclipse进行开发而来。系统多维的安全保障机制和简单易用的UI设计可以帮助用户安全、快捷、高效地管理私人账户及密码，让用户用得舒心的同时还能让用户用得放心。

protection software control platform

Abstract

With the advent of the information age, people are enjoying the great convenience

and benefits brought by information resources and also facing a severe test of

information security in the coming information age. Especially the exposure of "Prism"

incident three years ago raising the public attention to information to an unprecedented

height. People are becoming more urgent to protect their privates. On the other hand,

along with the further spreading of traditional Internet and prosperity of emerging

mobile Internet, people’s all kinds of social accounts and bank accounts information are

also increasing. Memory and management of a large number of the account password

have become a huge burden on the people.Therefore, the design of a secure and efficient

software to help users manage various accounts and passwords has become a very urgent

desire.

This paper mainly describes the design and development process of the above

software and related development knowledge.This system is an Android application

which focus on the protection of personal data.As a security software, there are many

strong data security mechanisms.The system uses the AES encryption algorithm, a

algorithm with higher security, efficiency and flexibility which can ithstand all known

attacks.And it has multiple security measures to protect user data, a login password

authentication, data encryption secret key authentication, user data can not be used

across devices, a non-secure state destroy data, program daemon control ,etc.The system

develop from SDK 4.4, SQLite, Eclipse under Windows environment.Multidimensional

security mechanism and easy used UI design can help users managing private accounts

and passwords more secure, fast and efficient. Allowing users to simultaneously get the

convenience and safety.
