中文摘要：

随着宽带无线接入技术和移动终端技术的飞速发展，人们迫切希望能够随时随地从互联网获取信息和服务，移动互联网应运而生并迅猛发展。然而，由于云计算平台、移动通信网络和移动终端的开放性，传统互联网服务中信息传播和管控机制不再适应于移动互联网，信息安全和用户隐私保护已经成为移动互联网用户迫切关心和亟待解决的问题。结合国内外移动互联网发展的最新趋势，对移动互联网服务和隐私保护方面的研究进行了展望。首先对当前移动互联网服务模型和移动互联网服务架构进行了评述；其次对当前的移动互联网数据传播控制机制以及隐私保护机制进行了分析和讨论；最终给出了一些潜在的研究热点，为未来研究工作指明方向。

英文摘要：

With the development of the broadband wireless access technology and mobile terminal technology, mobile internet arises at the historic moment and has been rapid development, by which users can easily obtain information and services from the internet anywhere at any time. However, owing to the openness of cloud computing platform, the mobile communication network and mobile terminals, information transmission and control mechanisms in traditional internet are no longer fit in with that in mobile internet, it is a key point for mobile internet to ensure information security and user privacy protection. Combined with the latest trend of the development of the mobile internet at home and abroad, a number of contributions to mobile internet service and privacy protection are made. First, an overview of mobile intemet service models and mobile internet services architectures is given. Second, the current data transmission control mechanisms and privacy protection mechanisms in mobile intemet are ravened and discussed. Finally, the potential research issues for the future research works are shown.
