An ICMetric Security System for Intelligent Wheelchairs Based on Triple MEMS Sensors

Abstract

Embedded systems are increasing in many areas, some examples of an embedded system are mobile phones, video game consoles, and industrial monitoring. Currently, interest with embedded systems is concerned with the issues of the providing safety, privacy and security. Security techniques rely on keeping the keys hidden, system can be exposed when the keys are described. We propose a system based on ICMetric that exploits the features of an embedded device to produce the identification of device. This paper proves that unique device features can be utilized to present an identity to a device which can be consumed for the providing security. The ICMetric technology has the facility to protect the systems by exploiting features of device. The proposed system uses the embedded MEMS magnetometer, gyroscope and accelerometer in the myAHRS_plus sensor to create a device ICMetric. An intelligent wheelchair is required which is equipped with the MEMS sensors. The proposed system is built on the features which have been produced by bias values of magnetometer, gyroscope and accelerometer. Reading generated from sensors are analyzed statistically to generate a triple ICMetric numbers used for device identification. The ICMetric number is not stored on the system and can be reproduced when necessary. If the system is attacked, there will be no theft because the ICMetric number is non-store. The proposal system proves that using MEMS sensors to generate an ICMetric number which using for device identification increase authentication and security of embedded devices.
