Authenticating Top-k Queries in Location-based Services with Confidentiality
State-of-the-art location-based services (LBSs) involve data owners, requesting clients, and service providers. As LBSs become new business opportunities, there is an increasing necessity to verify the genuineness of service results. Unfortunately, while traditional query authentication techniques can address this issue, they fail to protect the confidentiality of data, which is sensitive locat...

With the popularity of location-based services and the abundant usage of smart phones and GPS-enabled devices, the necessity of outsourcing spatial data has grown rapidly over the past few years. Meanwhile, the fast a rising trend of cloud storage and cloud computing services has provided a flexible and cost-effective platform for hosting data from businesses and individuals, further enabling m...
متن کاملEffective Management of Location Dependent Continuous Queries in Mobile Environment
Advances in wireless and mobile computing environments allow a mobile user to perform within a wide range of applications. For example, mobile users need to pull data about unfamiliar places or local life styles related to their location. Furthermore, a mobile user may be interested in getting location dependent query results periodically. We propose an algorithm for handling continuous queries...
متن کاملSkyline Queries
DEFINITION: Given a set of points p1, p2, ......., pn, the skyline query returns a set of points P, called as the skyline points, such that any point pi ∈ P is not dominated by any other point in the dataset. A point p1 dominates another point p2, if p1 is not worse than p2 in all dimensions and p1 is better than p2 in at least one dimension. In other words, a point p1 dominates another point p...
متن کاملSemi-Skyline Optimization of Constrained Skyline Queries
Skyline evaluation techniques (also known as Pareto preference queries) follow a common paradigm that eliminates data elements by finding other elements in a data set that dominate them. Nowadays already a variety of sophisticated skyline evaluation techniques are known, hence skylines are considered a well researched area. On the other hand, the skyline operator does not stand alone in databas...
