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 health-care, 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.
