Spirit: Security and Privacy in Real-Time Monitoring System

Abstract

In this paper, we investigate the effect of data size on mobile device’s computing power for different security protocol. Based on the fact that the computing power efficiency of security protocol may depend on the data size, we propose a system prototype, Spirit, which can minimize its computation power by selecting the security protocol dynamically according to different data types which may be of different data size, such as blood pressure, brain wave, overall health status, etc..
