Privacy Conscious Screening Framework for Frequently Moving Objects
S. P. Vijayaragavan, B. Karthik · 2014
The mainstay of this project is to monitor the continuously moving objects location and minimizes the number of location updates using PAM. The fundamental problem in a monitoring system is when and how a mobile client should send location updates to the server because it determines three principal performance measures of monitoring accuracy, efficiency and privacy. It is also proposed to optimize the performance of the framework. In particular the minimum cost update strategy shows that the safe region is a crude approximation of the ideal safe area, mainly because to separately optimize the safe region for each query, but not globally. A possible solution is to sequentially optimize the queries but maintain the safe region accumulated by the queries optimized so far. Then, the optimal safe region for each query should depend not only on the query, but also on the accumulated safe region by developing efficient query evaluation/reevaluation and safe region computation algorithms in the PAM framework.
