“…The AP-based approaches [30], [31] have been widely used for LBSs in mobile environments. In our approach, a user can send queries anytime and anywhere, and the query is generated in the format of (x, y), I, r, others , where (x, y) represents the exact location of the user, I represents the queried interest, r is the queried range and others include the user's identity, etc.…”

Abstract-Location-Based Service (LBS) has become a vital part of our daily life. While enjoying the convenience provided by LBS, users may lose privacy since the untrusted LBS server has all the information about users in LBS and it may track them in various ways or release their personal data to third parties. To address the privacy issue, we propose a DummyLocation Selection (DLS) algorithm to achieve k-anonymity for users in LBS. Different from existing approaches, the DLS algorithm carefully selects dummy locations considering that side information may be exploited by adversaries. We first choose these dummy locations based on the entropy metric, and then propose an enhanced-DLS algorithm, to make sure that the selected dummy locations are spread as far as possible. Evaluation results show that the proposed DLS algorithm can significantly improve the privacy level in terms of entropy. The enhanced-DLS algorithm can enlarge the cloaking region while keeping similar privacy level as the DLS algorithm.

“…A similar higher level primitive is location proofs, introduced by Saroiu et al [42]. In a typical usage scenario, a mobile device, seeking to prove its location may request a component of the local wireless infrastructure (such as a WiFi access point or a cell phone tower) to issue it a location proof.…”

Abstract-Wireless bodyworn sensing devices are fast becoming popular for fitness, sports training and personalized healthcare applications. Securing data generated by these devices is essential if they are to be integrated into the current health infrastructure and employed in medical applications. In this paper, we propose a mechanism to secure data provenance for these devices by exploiting spatio-temporal characteristics of the wireless channel that these devices use for communication. Our solution enables two parties to generate closely matching 'link fingerprints' which uniquely associate a data session with a wireless link such that a third party can later verify the details of the transaction, particularly the wireless link on which the data was transmitted. These fingerprints are very hard for an eavesdropper to forge, they are lightweight compared to traditional provenance mechanisms, and enable interesting security properties such as accountability, non-repudiation, and resist man-in-the-middle attacks. We validate our technique with experiments using bodyworn sensors in scenarios approximating actual device deployment, and present some extensions which reduce energy consumption. We believe this is a promising first step towards using wireless-link characteristics for data provenance in body area networks.

Abstract-Location-based Services (LBS) have gained popularity as a result of the advances in mobile and communication technologies. LBS provide users with relevant information based on their location. In spite of the desirable features provided by LBS, the geographic locations of users are not adequately protected. Location privacy is one of the major challenges in vehicular and mobile networks. In this article, we analyse the security and privacy requirements for LBS in vehicular and mobile networks. Specifically, this paper covers privacy enhancing technologies and cryptographic approaches that provide location privacy in vehicular and mobile networks. The different approaches proposed in literature are compared and open research areas are identified.
