The smartphone market is growing at a rapid pace. The security issues of smartphones are increasing, and preventive measures for smartphone loss are needed. The portability of smartphones has increased the risk of loss incidents, and the dangers of lass are increased by personal information leakage and subsequent damages. In this paper, we propose an enhanced security scheme through remote control for the prevention of smartphone loss through remote control to minimize such damages. The proposed scheme provides remote synchronization, blocking access to personal information, location tracking, remote camera control, and event log transferring. In addition, the scheme can prevent personal information leakages and increase the possibility of re-acquisition.
