Selecting Optimal Meeting Point with Security Measures

Malathi S Y, Maithri C

Protecting privacy in location based services is an important requirement in wireless communication. Many privacy preserving approaches exist that allow protecting privacy in location based services. These applications often rely on current (or preferred) locations of individual users or a group of users to provide the desired service, which jeopardizes their privacy users do not necessarily want to reveal their current (or preferred) locations to the service provider or to other, possibly un-trusted users. The main aim of privacy-preserving algorithms is determining an optimal meeting location for a group of users.Privacy evaluation is performed by formally quantifying privacy-loss of the proposed approaches.The performance of privacy preserving algorithms is determined by implementing and testing their execution efficiency on Nokia smart phones. Further study is carried out to get an insight into the privacyawareness of users in location based services and the usability of the proposed solutions.
