Digital Twins in Healthcare: Security, Privacy, Trust and Safety Challenges

The health sector is a critical and vulnerable infrastructure, making it an easy target for hackers and attackers. Healthcare is also a highly trusted sector that contains sensitive and personal information; therefore, exploiting its vulnerabilities can lead to great financial and political gains. The digital twin is an emerging technology that could play a powerful role in the healthcare sector in the future, for example, offering customized diagnosis and treatment to each patient. Although digital twins come with several advantages, there are several challenges to implementing digital twins successfully in healthcare. In this paper, we have discussed the different challenges related to the security, privacy, trust, and safety of digital twins and its implementation in healthcare. We have also presented the comparative conflict analysis of implementing the security, safety, privacy, trust, and operational requirements for IoT digital twins.
