A Denial of Service (DoS) is a computer crime where machines and other resources are
made unavailable to its legitimate users by flooding the resources with unwanted requests …

Despite the critical role that range queries play in analysis and visualization for HPC
applications, there has been no comprehensive analysis of indices that are designed to …

In today's society, an increasing number of users and enterprises encrypt substantial
amounts of data, including spatial text data, and outsource it to cloud servers. However …

Geometric range query is a general query algorithm over spatial data and applies to many
real-world applications, such as location-based services. Considering the sensitivity of …

We propose an efficient privacy-preserving, content-protecting location-based service (LBS)
scheme. Our proposal gives refined data classification and uses generalised ElGamal to …

Based on hybrid encryption algorithms, this paper presents a novel location privacy
protection scheme with the aid of the cloud server. The scheme can effectively protect both …

Location‐based services (LBS) leverage the geographical information of a device to deliver
information, entertainment, and other services tailored to the user's present location. LBS not …

Privacy and integrity preservation of user data is a major challenge in the context of location
based services, as the assumption of trusted relationship between the user and the service …

Range search of spatial data, has been applied in many scenarios such as geometric
queries, location-based services, and computational geometry, etc. Due to the increasing …

Geometric range query is an essential operation in many applications, including location-
based service, querying on sensor networks, and computational geometry. In the Internet of …
