Abstract: Limited resources and user information leak restrict the development and promotion of location-based services (LBS) applications. By combining the powerful computing power and storage capacity of cloud computing and the high-speed mobile network in the development of 3G network, a development model with a mobile terminal and cloud server-side are adopted. It can deliver complicated computing tasks and storage tasks at the mobile end to the cloud which has high-speed computing power and massive storage capacity. In addition, this paper proposes an information push strategy based on relations and states, which can well protect the user’s location and other private information, and provide users with flexible permission settings. It is showed feasibility and practicality of the system through operation of a prototype system.
