A Proactive Digital Chain of Custody for Internet of Healthcare Things (IoHT) Data

The increased use of the Internet of Healthcare Things (IoHT), i.e., Internet of Things devices used in healthcare, highlights the need to support continuous gathering and maintenance, leading to challenges in preserving healthcare data security and privacy. This paper briefly examines these challenges and proposes an end-to-end proactive Digital Chain of Custody (DCoC) when using IoHT. It outlines an IoHT-DCoC using concepts, such as data accountability using datakeeper software and dynamic data logging built on data encryption. Finally, an attribute-based access control (ABAC) model is developed that proactively ensures end-to-end data security and privacy.
