Abstract

In this paper, we propose a method for detecting physical shock by a mobile phone and its applications in security and emergency scenarios. We use acceleration signal provided by accelerometers integrated in a mobile phone to detect shocks. The shock is identified by analysis of acceleration pattern using statistical signal processing methods. We propose to use such a shock detection application for increasing security of data access in a mobile phone, as well as identifying scenarios which user of mobile phone experiences risky emergency events.
