Description

Mobile Online Social Networks (mOSNs) have recently grown in popularity. With the ubiquitous use of mobile devices and a rapid shift of technology and access to OSNs, it is important to examine the impact of mobile OSNs from a privacy standpoint. Location sharing is a fundamental component of mobile online social networks (mOSNs), which also raises significant privacy concerns. The mOSNs collect a large amount of location information over time, and the users’ location privacy is compromised if their location information is abused by adversaries controlling the mOSNs. With the development of real time localization and mobile computing technology, it becomes increasingly popular for sharing individual locations in mobile Online Social Network (mOSN), which inevitably raises significant concerns on the privacy of users’ locations. Mobile online social networks (mOSNs) become more and more popular, and compared with traditional OSNs, mOSNs take a step further in that they provide the location-based services, which also raise significant privacy concerns. Location sharing is a fundamental component of mOSN, however, users may be hesitant to share locations if privacy is not guaranteed. Existing system used some location sharing system that provides flexible location in mOSNs. They cannot prevent the location server form linking the queries from the same user and extract sensitive information. In this project, the system propose a novel solution achieving social network privacy and location privacy. The proposed system cannot be linked to the same user. It improve the privacy. Compared to the existing system our system encrypt more location information form the server.
