Authenticating IoT Devices Using Multimodal Biometric and Blockchain: A Personalised Healthcare Scenario

The Internet of Things (IoT) has become an integral part of today's life as IoT solutions integrate equally into households and industrial sectors. However, with the widespread adoption of IoT devices, there is an increasing concern for privacy preservation and device integrity. The concerns are due to the continuous collection of extensive data encompassing personal movements, behaviours, and preferences and the sending of that data for further storage in various data centres by such devices. Recently, researchers have taken a great interest in blockchain-based techniques in response to these challenges in various relevant domains.
