The emergence of location-based social networks, or geo-social networks (GSN), allows users to share their whereabouts with friends, to find nearby contacts, and to provide/search for recommendations about points of interest that are close to their current geographical coordinates. Furthermore, users can act as mobile sensors in various location-centric crowd-sourcing scenarios, such as monitoring the levels of vehicle traffic congestion, or the levels of air pollution. Such applications require users to disclose their locations in one form or another, which raises serious privacy concerns. With knowledge of user locations, a malicious adversary can stage a broad spectrum of attacks against individuals, from physical surveillance and stalking, to identity theft, to inferring sensitive information, such as the individual's health status, alternative lifestyles, political and religious affiliations, etc. Preserving location privacy is an essential requirement towards the successful deployment of location-based applications. Currently, there are several related use-case scenarios in which some form of location sharing is necessary, and for which privacy must be preserved. First, users send location-based queries to un-trusted servers that store databases of points of interest. In this case, the privacy objective is to allow the users to retrieve nearby points of interest without having to disclose exact locations to the location service provider. Second, commercial entities that users trust with their locations, such as a telephone company, or an online GSN, wish to perform collaboratively a computation in the form of data matching with spatial predicates, for data mining tasks that enhance the user experience by synthesizing profiles, or increase the companies' revenue. Each party will contribute its own dataset of locations, but only in anonymized form, and only the results of the computation should be revealed to each party, without gai

Location-based applications refer to those that use location data in a prominent manner. Location data can be very effective for service provisioning, enabling the birth of a new generation of information services. Although data security and privacy issues have been extensively investigated in several domains, current techniques are not readily applicable to location-based applications. Conciliating the effectiveness of these applications with privacy concerns constitutes a unique challenge, mostly due to the semantic richness of location and time information. Research in this field involves aspects of spatio-temporal reasoning, query processing, system security, statistical inference, and more importantly, anonymization techniques. Several research groups have been working in recent years to identify privacy attacks and defense techniques in this domain. This state-of-the-art survey provides a solid ground for researchers approaching this topic to understand current achievements through a common categorization of privacy threats and defense techniques. This objective is particularly challenging considering the specific (and often implicit) assumptions that characterize the recent literature on privacy in location-based services. The book also illustrates the many facets that make the study of this topic a particularly interesting research subject, including topics that go beyond privacy preserving transformations of service requests, and include access control, privacy preserving publishing of moving object data, privacy in the use of specific positioning technology, and privacy in vehicular network applications.

Location-based service (LBS) is gaining momentum as GPS-equipped mobile devices become increasingly affordable and popular. One of the potential obstacles faced by LBS is that users may raise concerns about their personal privacy when location data are sent to a distrusted LBS provider. A well-known solution is to render the location data less accurate through spatial or temporal cloaking. However, such a solution has limitations when the LBS is based on location data that either include speed and heading direction, or are sent at a regular time interval. In the former case, by combining consecutive location data including speed, heading direction, and cloaked locations, an adversary can obtain more accurate estimation of the actual location. In the latter case, an adversary can infer additional information when an expected update to the location data is not received because cloaking is not possible. In this thesis, we will first show how privacy protection provided by spatial cloaking can be breached, and proposed a new cloaking method to integrate the speed and direction into the spatial cloaking process. We then propose an auditing system to ensure all the mobile devices can be well protected even when it is impossible to cloak some of them to meet their customized privacy requirements. We evaluate the proposed methods with experiments based on simulated mobile devices using real city maps. The experiments show that our speed and direction cloaking methods can achieve sufficient privacy protection without causing significant decrease in the service quality.

Location-based services (LBS) are a new concept integrating a user’s geographic location with the general notion of services, such as dialing an emergency number from a cell phone or using a navigation system in a car. Incorporating both mobile communication and spatial data, these applications represent a novel challenge both conceptually and technically. The purpose of this book is to describe, in an accessible fashion, the various concepts underlying mobile location-based services. These range from general application-related ideas to technical aspects. Each chapter starts with a high level of abstraction and drills down to the technical details. Contributors examine each application from all necessary perspectives, namely, requirements, services, data, and scalability. An illustrative example begins early in the book and runs throughout, serving as a reference. · This book defines the LBS field and identifies its capabilities, challenges, and technologies. · The contributors are recognized experts from academia and industry. · Coverage includes navigation systems, middleware, interoperability, standards, and mobile communications. · A sample application, the "find-friend" application, is used throughout the book to integrate the concepts discussed in each chapter.

This book delivers concise coverage of classical methods and new developments related to indoor location-based services. It collects results from isolated domains including geometry, artificial intelligence, statistics, cooperative algorithms, and distributed systems and thus provides an accessible overview of fundamental methods and technologies. This makes it an ideal starting point for researchers, students, and professionals in pervasive computing. Location-based services are services using the location of a mobile computing device as their primary input. While such services are fairly easy to implement outside buildings thanks to accessible global positioning systems and high-quality environmental information, the situation inside buildings is fundamentally different. In general, there is no simple way of determining the position of a moving target inside a building without an additional dedicated infrastructure. The book’s structure is learning oriented, starting with a short introduction to wireless communication systems and basic positioning techniques and ending with advanced features like event detection, simultaneous localization and mapping, and privacy aspects. Readers who are not familiar with the individual topics will be able to work through the book from start to finish. At the same time all chapters are self-contained to support readers who are already familiar with some of the content and only want to pick selected topics that are of particular interest.

Location-aware computing is a technology that uses the location (provides granular geographical information) of people and objects to derive contextual information. Today, one can obtain this location information free of cost through smartphones. Smartphones with location enabled applications have revolutionized the ways in which people perform their activities and get benefits from the automated services. It especially helps to get details of services in less time; wherever the user may be and whenever they want. The need for smartphones and location enabled applications has been growing year after year. Nowadays no one can leave without their phone; the phone seemingly becomes one of the parts of the human body. The individual can now be predicted by their phone and the identity of the phone becomes the person’s identity. Though there is a tremendous need for location-enabled applications with smartphones, the debate on privacy and security related to location data has also been growing. Privacy and Security Challenges in Location Aware Computing provides the latest research on privacy enhanced location-based applications development and exposes the necessity of location privacy preservation, as well as issues and challenges related to protecting the location data. It also suggests solutions for enhancing the protection of location privacy and therefore users’ privacy as well. The chapters highlight important topic areas such as video surveillance in human tracking/detection, geographical information system design, cyberspace attacks and warfare, and location aware security systems. The culmination of these topics creates a book that is ideal for security analysts, mobile application developers, practitioners, academicians, students, and researchers.
