Abstract :
Spatial data consists of geographic and geometric data primitives. Searching on spatial data is carried by geometric range queries. FastGeo, an efficient two-level search scheme is introduced. The major contributions focus on two aspects. First, enrich search functionalities by designing new solutions to carry out fundamental geometric search queries, which are supported over encrypted data. Second, minimize the gap between theory and practice by building novel schemes to perform geometric queries with highly efficient search time and updates over large scale spatial data. Spatial data and geometric range queries are converted into a new form, denoted as equality-vector form and perform two-level search to verify whether a point is inside a geometric range. FastGeo is implemented using java as programming language on Net Beans IDE. An honest-but-curious server efficiently performs geometric range queries and returns data points that are inside the geometric region to the client without learning query or sensitive information. Better privacy can be achieved which cannot drop or create a new message. Experimental results on spatial data can achieve sublinear search time.
