A review paper on preserving privacy in mobile environments

摘要: Technology is improving day-by-day and so the usage of mobile devices. Every activity that would involve manual paper transactions can now be completed in seconds using your fingertips. On one hand, life has become fairly convenient with help devices, whereas on other hand security data occurring process have been under continuous threat. This paper, re-evaluates different policies procedures used for preserving privacy sensitive device location. Policy languages very vital environments as they extended/used significantly sending/receiving any data. In environment users always go to service providers access various services. Hence, communications between handsets needs secured. Also, control place. A section this will review communication paths channels their related criteria. a contribution domain, showing possible attacks mechanisms preserve end-user privacy. addition, it also gives comparison methods provide guidance readers. Finally, summarizes future research challenges area preservation. examines 'where' problem particular, tradeoffs enforcing location at vs. an edge server. sketches implementation solution both server presents detailed experiments real mobility user profile sets collected from multiple sources (taxicabs, Smartphones).
