Blockchain Framework for Securing Ambient Health Care Systems

In the world of wearable technology, smart homes and cities, innovation continues to thrive. Computing is pervasive, and ambient computing is ubiquitous integration of computer into the background of everyday environments and situations. With contact-free sensors and wearables that require interaction, ambient computing is increasingly finding use in the healthcare industry. This ubiquitous nature of ambient computing raises concerns on privacy, confidentiality, data protection, informed consent and fairness. The continuous collection of massive health care data not only unobtrusively monitors the health condition of the patient and trajectory for high quality care but also has a detrimental effect in terms of privacy, bias and fairness. This paper discusses the main ethical issues in ambient health care systems and explores the blockchain based solutions for ambient health care systems emphasizing on patient dignity and autonomy. Furthermore, a secure EHR access using RBAC and Cryptographic techniques for the responsible development and use of ambient health care systems is proposed in this research work.
