Abstract: With the development of ubiquitous computing, positioning technology and mobile communication technology, mobile data management has been widely used in many applications. Privacy preserving is one of the most critical issues in the field of mobile data management. People expect to get high-quality services, as well as the privacy preserved. This paper mainly discusses the membership query which concerns about whether there are moving objects in some areas, and proposes a method called BFSQ(Bloom filter-based spatial query) to solve this query which is well performed in privacy preserving and makes sure of high quality of services. Experimental results show the effectiveness and efficiency of the proposed method.
