Terminal security protection method and system

The invention discloses a terminal security protection method and system. The method comprises the following steps: acquiring a to-be-authenticated face image in a preset range of a current terminal through a camera; then, when the to-be-authenticated face image comprises at least two face images, matching the to-be-authenticated face image in a pre-established authorized personnel library, and when a matching result is that all the face images are matched, allowing the terminal to be operated, and when the to-be-authenticated face image is only one face image, allowing the terminal to be operated. If yes, the terminal is locked so as to reject the operation, the important terminal equipment can be effectively prevented from being checked and even used by an unauthorized person during use, and the use safety of the terminal is improved. 本发明公开了一种终端安全防护方法及系统，该方法包括：先通过所述摄像头获取当前终端的预设范围内的待认证人脸图像；然后当所述待认证人脸图像包括至少两个人脸图像时，将所述待认证人脸图像在预先建立的授权人员库中进行匹配，并在匹配结果为全部匹配时，则允许操作终端，并且在所述待认证人脸图像仅为一个人脸图像时，则将所述终端进行锁定从而拒绝操作，能够有效地避免重要
