Privacy, Location Based Application, People Location Information Service, High Performance
Location privacy concerns are main issue of location based application. For protecting privacy, it is necessary to encrypt location information. However, there exists a trade-off between higher speed and higher security because of data encryption time. In this paper, we propose a privacy management mechanism to control two conflicting factors – higher speed and higher privacy protection. At first, we investigate the performance of various encryption algorithms and analyze kind of location information. Eventually, we’ve designed a privacy management mechanism which enables user’s system both to protect location privacy and to maintain high system performance.
