“…All forms of data obscuring (except encryption) involve some degree of data quality degradation. Options for obscuring location data include: removal, 4 encryption, 12 cloaking, 11 adding noise, 10,13 decreasing the resolution, 14 and simulation. [15][16][17][18] Of note, modern methods for simulating synthetic data can provide nuanced data that can be minimally "lossy" while preserving privacy.…”

Location data are becoming easier to obtain and are now bundled with other metadata in a variety of biomedical research applications. At the same time, the level of sophistication required to protect patient privacy is also increasing. In this article, we provide guidance for institutional review boards (IRBs) to make informed decisions about privacy protections in protocols involving location data. We provide an overview of some of the major categories of technical algorithms and medical-legal tools at the disposal of investigators, as well as the shortcomings of each. Although there is no "one size fits all" approach to privacy protection, this article attempts to describe a set of practical considerations that can be used by investigators, journal editors, and IRBs.

“…He et al provided a publish‐subscribe system with secure proxy decryption in mobile social networks, which is based on cipher‐policy A B E and public‐key encryption with keyword search. Xie et al propose a privacy‐preserving LBS scheme based on the RSA algorithm and ciphertext policy attribute‐based encryption scheme, involving a Trusted Authority.…”

Summary With the dramatic growth of smart phones and social network services, location‐based service has become increasingly popular in our daily life, which also brings great privacy leakage about user's location information. Thus, privacy‐preserving location sharing is still a significant problem. In this paper, two models of our scheme are verifiable, supporting location query on homomorphic encrypted ciphertext with searching index and trapdoor. The characteristics of our scheme are that it (1) allows users to share their current location without leaking any location information to the untrusted server; (2) protects users from the cheating of untrusted server's malicious behavior by verifying query result; (3) supports a novel personalized query according to users' classifications of social network friends; (4) the user does not have to be online to make permissions for accessing his shared location, and (5) model 2 does not rely on any trusted third party server to perform any computation. The security analysis shows that it ensures secure location sharing in social scenarios.

“…Protection of data is a critical issue and has been an active area of research (Yao et al, 2013;Chow et al, 2009). Numerous approaches have been proposed and implemented including various routing and encryption techniques (Karimi & Kalantari, 2018;Xie & Wang, 2016) in order to prevent the data leakage to the adversaries. Adversaries are the ones who attack the network when the data is being transmitted.…”

Location privacy is one of the most challenging threats that has grown to acquire attention across the globe. Wireless sensor network (WSN) where the transmission occurs through multiple hops between the nodes suffers from attacks such as backtracking and directional attacks by the adversaries. As an analogy, sensor nodes employed in wildlife monitoring region to constantly monitor their presence and activities are threatened by attackers. The attackers constantly monitor the transmission with the objective of locating the source node ultimately leading to poaching. In order to do away with these threats leading to location disclosure, various routing mechanisms that involves phantom node, fake packets and fake source nodes have been proposed time and then by various researchers. In this paper we present a comprehensive study of various routing mechanisms for source location privacy preservation that are compared on four parameters: i. safety period ii. energy consumption iii. Packet latency iv. Network life time. Different routing mechanisms are analyzed in detail and future scope for improvement is provided to enhance further research.
