Enabling Efficient and Geometric Range Query With Access Control Over Encrypted Spatial Data
IEEE Transactions on Information Forensics and Security, 2019As a basic query function, range query has been exploited in many scenarios such as SQL retrieves, location-based services, and computational geometry. Meanwhile, with explosive growth of data volume, users are increasingly inclining to store data on the

Efficient Privacy-Preserving Spatial Range Query Over Outsourced Encrypted Data
IEEE Transactions on Information Forensics and Security, 2023With the rapid development of Location-Based Services (LBS), a large number of LBS providers outsource spatial data to cloud servers to reduce their high computational and storage burdens, but meanwhile incur some security issues such as location privacy

Comprehensive Survey on Privacy-Preserving Spatial Data Query in Transportation Systems
IEEE transactions on intelligent transportation systems (Print), 2023With the rapid development of Intelligent Transportation System (ITS), a large number of spatial data are generated in ITS. Although outsourcing spatial data to the cloud server can reduce the high local computation and storage overheads, it will also ...

3D BIM-enabled spatial query for retrieving property boundaries: a case study in Victoria, Australia
International Journal of Geographical Information Science, 2019In the cadastral system of Victoria, the legal extent of properties is defined by a wide range of property boundaries referencing physical objects. These boundary types are typically represented in 2D plans. However, to address the challenges of 2D plans

Flexible Location-Based Spatial Queries
2007A model for representing and evaluating flexible Location-Based Spatial Queries (LBSQ) is proposed. In a LBSQ the selection condition is generally a constraint on the distance of the objects in the database (instances) from the user location. Such queries are becoming more and more useful in location-based services such as those provided by cell-phones,
