As the U disk using high frequency,easy to lose,this paper puts forward an intelligent plug and remind with safety protection system,the system can automatically perform,monitoring U disk is removed according time,to ensure the U disk data security,at the same time to verify a user's identity,to ensure the safety of user authentication.The experiment shows that the system is small,green and no need to install,and comes with the encryption function,which can effectively prevent the loss of U disk and ensure the security of personal data after it is lost.%针对U盘使用频率高,易遗失的问题,提出了一种智能插拔提醒及安全防护系统,该系统能够自动执行,根据时间监控U盘是否取走,保证了U盘数据的安全,同时能够验证使用者的身份,确保用户认证的安全.实验表明,系统体积小、绿色无需安装,并附带加密功能,能够有效防止U盘遗失及确保遗失后个人数据的安全.
