Hiding User Privacy for Location Sharing Services in Social Networks Manu Manjunath,Pavan Kumar Kuppalu Basavarajappa, Sharath Ramesha Department of Computer Science, Texas A&M University-Kingsville Abstract— A location sharing service is one of the services offered by location based services (LBS) which allows a group of people to share their locations. With an not so trustworthy servers around, such a location sharing services (LSS) may intimidate the privacy of users. Current solutions for hiding user privacy for Location Sharing Services (HUPLSS) need a trusted third party which can access the exact locality of all users in the system or depend on algorithms or protocols for computations or communication overhead. In this paper, …show more content…

1.1 Problem Identification The problem is with centralized server that is it can produce complete information about the user i.e., location , time and number of times the user visited the certain place and which in turn breaches the privacy issues [5]-[7]of the user. Current privacy preserving techniques target at preserving user privacy by protecting the centralized server to some extent .However, it is not able to fully protect the user privacy because center server identifies the user location [8]-[11]. While other techniques need some information to exchanged not only between user and centralized server but also with their friends.[12][13].Other techniques make use of NAT(network address translation) where user devices communicate with the intermediate server directly thereby avoiding direct communication with the device[14]-[15]. …show more content…
