嵌入式Linux系统智能手机防盗追踪功能的实现

防盗追踪功能是智能手机的一项重要安全技术,基于嵌入式Linux操作系统的智能手机尚未实现这一功能。本文设计了一种利用非法用户的手机号在系统后台以隐蔽方式向合法用户预先准备的安全手机号码发送特殊短信的防盗追踪技术,是通过修改刷机文件、定制智能手机的嵌入式Linux系统来实现的。改造的嵌入式Linux系统在手机开机启动的过程中能够运行特定程序,通过执行shell命令侦测手机sim卡的合法性来触发防盗报警功能。

Cell-phone Burglarproof Tracing Function Realization on Embedded Linux System

The burglarproof tracing function is one of the important security techniques of the intelligent cell phone not yet realized on cell-phones based on the Embedded Linux System. This article introduces a burglarproof tracing technique, that is, sending special text massages secretly at the backstage of the system from the illegal subscriber's number to the safe number which has been prepared by the legal subscriber, which is to be realized through the modification of firmware in the embedded Linux operating system. The modified system activates the burglarproof alarm function, when the cell-phone is turned on, through the running of a definite program, to test the legality of the SIM card with the shell order.
