Title
An Adaptive Dummy-based Mechanism to Protect Location Privacy in Smart Health Care System
Abstract
Advances in the scientific and technological revolution have engendered the spurt development of smart health care system (SHS). In SHS, Patients' location in-formation is transmitted to the designated medical service provider by sensors and wearables attached to patients' bodies for professional and quality assessment. The location information combined with time slot can disclose patients' sensitive privacy, including mental status, sensitive location, financial circum-stance. Thus, it demands our devoted attention and instant action to protect patient's location privacy, especially sensitive locations in SHS. In the privacy mechanisms based on location anonymizer, they are vulnerable to suffer collusion attacks and subjected to essentially compromise. In this paper, an adaptive dummy-based mechanism is proposed to preserve patients' sensitive locations, consisting of dual strategies, which are considering the direct distance between the generated false trajectories and the sensitive positions and weighing the sensitive locations. Extensive experiments are implemented to evaluate performance. The validity and feasibility of our proposed approach in protecting sensitive locations are indicated by simulation consequences compared with existing methods.
