《手机防盗系统的设计与实现》毕业学术论文.doc

摘 要 随着科技的不断发展，手机逐渐成为生活的必需品。传统的手机逐渐退出历史舞台。以Android系统为主的智能手机由于功能强大、价格低廉，俘获了大众的心。手机上会存储大量的信息，包括通讯录、短信、照片、银行卡密码等。个人隐私信息容易被别人无意看到或有意窃取。一旦手机丢失，可能这些隐私泄露了，还可能导致亲戚朋友上当受骗，对人们的工作和生活产生极大的影响，给用户造成不可挽回的损失，所以针对此问题开发一款功能简单好用的手机防盗软件必不可少。 本软件可以通过简单的设置，就可以通过亲友手机发送短信就可以实现手机定位、锁屏、响警报、销毁数据，还有丢失手机换SIM卡会自动向亲友手机发送提醒。这样一款简单实用，软件所占内存较小的手机防盗软件，通过模拟器和真机测试，适合Android 2.3及以上的手机，上述功能均已实现。 关键词：Android；手机防盗；广播机制；短信 ABSTRACT With the continuous development of science and technology, mobile phone has gradually become the necessities of life. The traditional phone gradually withdrew from the historical stage. Android smartphones have captured the public's heart due to its powerfulness, low price.
