Blockchain-Based IoT Forensics: Challenges and State-of-the-Art Frameworks

Abstract

There is no doubt that the recent emergence of Internet of Things (IoT) paradigm brings significant changes in many aspects of our life including smart homes, smart cities, healthcare, farming, etc. Despite the unlimited advantages of IoTs, the tremendous increase of interconnected smart devices attracts more threats and hence introduces many challenges related to the security and digital forensics of the IoT environment. Although the IoT forensics is relatively new domain of research, several IoT forensics frameworks have been proposed recently to investigate cybercrimes. However, blockchain-based IoT forensics is the most promising approach. This chapter introduces the digital forensics from the point of view of IoT environment. It also discusses recent IoT forensics challenges and presents the most recently developed blockchain-based frameworks for the IoT forensic.
