中文摘要：

随着移动终端设备的进步与发展以及互联网的高速发展，人们的生活越来越依赖于互联网和移动终端设备。为了保护企业的商业机密以及用户的个人隐私，文章通过限制接收方对图片的控制权，并且在一定时段内自动销毁未授权用户接收的图片，使发送方的隐私权得到保护。基于移动互联的客户-服务器系统，充分利用服务器的下载上传功能，使其一次只能下载一张照片，从而不断替换掉已有的照片，并利用 Android 系统自带的 handler 多线程的延时功能，实现了照片的定时显示，使接收方在能够看见发送方的图片的同时却不能控制发送方的图片，保护发送方的隐私。使用过程简单明了，不需要过于复杂的操作。

英文摘要：

With rapid development of mobile terminal equipment and the Internet, people＆#39;s lives are increasingly dependent on the Internet and mobile terminal equipment. In order to protect the commercial secrets of enterprises and the privacy of users, the access control of the picture is limited and the unauthorized user is automatically destroyed in a certain period of time to protect the sender＆#39;s privacy. Based on the application of mobile Internet client-server system, this technology limits users to only download a photo once, so as to constantly replace an existing photo. The handler mechanism based on Android is used to display photos in a period. At the same time, the recipient can see the received photo which cannot be controlled. As above, the privacy of sender can be protected.
