Security System Approach With pressure Sensor

Abstract

The increased usage of smart wearable in various applications, specifically in health-care, emphasizes the need for secure communication to transmit sensitive health-data.  practically, where multiple devices are carried by a person, a common secret key is essential for secure group communication. In this paper, we present a novel solution to generate and distribute group secret keys by exploiting on-board accelerometer sensor and the unique walking style of the user, i.e., gait. We propose a method to identify the suitable samples of accelerometer data during all routine activities of a subject to generate the keys with high entropy. In our scheme, the Smartphone placed on waist employs fuzzy vault, cryptographic practical applications. Suitable construct, and utilizes the acceleration due to gait, a common characteristic extracted on all wearable devices to share the secret key. We implement our solution on commercially available off-the-shelf smart wearable's, measure the system performance, and conduct experiments with multiple subjects. Our results, and is suitable for demonstrating that the proposed solution has a bit rate of 750 bps, low system overhead, distributes the key securely and quickly to all legitimate devices we have presented our novel protocol for group secret key generation and secure key distribution for multiple smart wearable devices. Our solution leverages the accelerometer sensor available on the off-the-shelf wearable devices and the unique walking characteristics of the user. We have presented a method to detect the suitable samples of sensor data dynamically to ensure the generation of the secret keys with good entropy during different activities. The secure key distribution process extracts the acceleration due to gait on all the smart devices and exploits this as a common characteristic to share the keys using the fuzzy vault. The solution is implemented on real wearable devices.
