**9. Appling ICMetric technology in intelligent wheelchairs**

In this chapter, ICMetric technology is integrated into an intelligent wheelchair. In order to ensure effective usage of the intelligent wheelchair and the need to protect the safety of each wheelchair, it is advantageous to provide identification of intelligent wheelchair to confirm the user's right to access the system and information and defend against identity theft and fraud. For achieving these aims, ICMetrics represents a new method for generating unique identifiers for embedded devices and improves security by reducing fraudulent activity.

ICMetric technology can improve secure communication between devices, reduce fraudulent activity, prevent unauthorised access to the systems and devices connected with the wheelchair, implicit detection of tampering of the software or hardware associated with the wheelchair, and prevent the fraudulent cloning or imitation of the electronics associated with the wheelchair.

While many security techniques are now developed, these cannot necessarily defend against unauthorised activity when the security and safety cannot be absolutely assured. The use of ICMetric technology to provide identification represents a new concept of controlling access to devices and is explicitly aimed at providing protection against attacks and improving security.

The ICMetric security system proposed in this chapter uses bias readings that have been extracted from sensor devices. These readings exploited to create ICMetric basis numbers that were working as identification for device.

In this chapter, suitable features can be gotten from the sensors to describe behaviour of intelligent wheelchair such as the gyroscope, magnetometer, and accelerometers. The offset is utilised in the sensor measurement to propose a security system that apply an ICMetric basis number using the sensor bias readings.
