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 internet service models and mobile internet services architectures is given. Second, the current data transmission control mechanisms and privacy protection mechanisms in mobile internet are ravened and discussed. Finally, the potential research issues for the future research works are shown.
