“…Along with this transition process, location sharing, as the fundamental means of enabling people to share their locations with designated friends, has always been a critical building block of implementing LBSs over mOSNs. For example, Foursquare * * * is one of the most popular geosocial service providers that allow users to register their current locations and share their location information with nearby friends or strangers [2].…”

Location sharing services have recently gained momentum over mobile online social networks (mOSNs), seeing the increasing popularity of GPS-capable mobile devices such as smart phones. Despite the convenience brought by location sharing, there comes severe privacy risks. Though many efforts have been made to protect user privacy during location sharing, many of them rely on the extensive deployment of trusted Cellular Towers (CTs) and some incur excessive time overhead. More importantly, little research so far can support complete privacy including location privacy, identity privacy and social relation privacy. We propose SAM, a new System Architecture for mOSNs, and P 3 S, a Privacy-Preserving Protocol based on SAM, to address the above issues for privacypreserving location sharing over mOSNs. SAM and P 3 S differ from previous work in providing complete privacy for location sharing services over mOSNs. Theoretical analysis and extensive experimental results demonstrate the feasibility and efficiency of the proposed system and protocol.

“…Nonetheless, these services expose the sensitive information of users such as their location and the location privacy is especially concerned in these systems. Recently, there have been many researches which are conducted to tackle this problem [54][55][56][57]. In the research of [16], the negative survey was used to resolve the problem.…”

Social networks have become part of today's life; however, they also create numerous privacy problems for their users as they reveal sensitive information. Thus, the privacy preservation has become a big problem in social networks and there are several researches related to this topic. However, the current research achievements for this issue are only ad hoc solutions and the broad picture of the problem is not clear. This paper surveys a wide range of related researches and realises that the topic includes many sub-areas; for example, the privacy in publishing social network data for the use of third-party consumers or the privacy of users in the leakage of individuals' information to unexpected people in their social circle. The study also analyses the advantages as well as limitations of proposed solutions. On the basis of that the research outlines key outstanding issues and recommends directions for the future research. Moreover, the research also investigates common privacy metrics and popular privacy-preserving techniques to provide readers some basic tools to resolve open problems in the topic. The ultimate purpose of this research is to pave a solid background for people, who are interested in the topic, to do research further.

“…Schlegel et al proposed an Order‐Retrievable Encryption notion for privacy‐reserving location sharing, without any third party, achieving lower communication between a user and a server, but the scheme did not give a full verification for the query result and it needed to share pre‐established secret among friends. Son et al introduced a pseudonym scheme based on Lagrange polynomial with the public social network IDs of the designated friends, without pre‐established secret among friends and a trusted server. To detect whether a position is within a given circular area in a privacy‐preserving way, Li et al proposed the first encryption scheme for inner product range and designed a privacy‐preserving tree index structure.…”

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.
