A critical literature review of security and privacy in smart home healthcare schemes adopting IoT & blockchain: problems, challenges and solutions
Protecting private data in smart homes, a popular Internet-of-Things (IoT) application, remains a significant data security and privacy
challenge due to the large-scale development and distributed nature of IoT networks. Recently, smart healthcare has leveraged smart
home systems, thereby compounding security concerns in terms of the confidentiality of sensitive and private data and by extension the
privacy of the data owner. However, PoA-based Blockchain DLT has emerged as a promising solution for protecting private data from
indiscriminate use and thereby preserving the privacy of individuals residing in IoT-enabled smart homes. This review elicits some
concerns, issues, and problems that have hindered the adoption of blockchain and IoT (BCoT) in some domains and suggests requisite
solutions using the aging-in-place scenario. Implementation issues with BCoT were examined as well as the combined challenges BCoT
can pose when utilised for security gains. The study discusses recent findings, opportunities, and barriers, and provide recommendations
that could facilitate the continuous growth of blockchain application in healthcare. Lastly, the study then explored the potential of using
a PoA-based permission blockchain with an applicable consent-based privacy model for decision-making in the information disclosure
process, including the use of publisher-subscriber contracts for fine-grained access control to ensure secure data processing and sharing,
as well as ethical trust in personal information disclosure, as a solution direction. The proposed authorisation framework could guarantee
data ownership, conditional access management, scalable and tamper-proof data storage, and a more resilient system against threat
models such as interception and insider attacks
Securing Our Future Homes: Smart Home Security Issues and Solutions
The Internet of Things, commonly known as IoT, is a new technology transforming businesses, individuals’ daily lives and the operation of entire countries. With more and more devices becoming equipped with IoT technology, smart homes are becoming increasingly popular. The components that make up a smart home are at risk for different types of attacks; therefore, security engineers are developing solutions to current problems and are predicting future types of attacks. This paper will analyze IoT smart home components, explain current security risks, and suggest possible solutions. According to “What is a Smart Home” (n.d.), a smart home is a home that always operates in consideration of security, energy, efficiency and convenience, whether anyone is home or not
BlockChain: A distributed solution to automotive security and privacy
Interconnected smart vehicles offer a range of sophisticated services that
benefit the vehicle owners, transport authorities, car manufacturers and other
service providers. This potentially exposes smart vehicles to a range of
security and privacy threats such as location tracking or remote hijacking of
the vehicle. In this article, we argue that BlockChain (BC), a disruptive
technology that has found many applications from cryptocurrencies to smart
contracts, is a potential solution to these challenges. We propose a BC-based
architecture to protect the privacy of the users and to increase the security
of the vehicular ecosystem. Wireless remote software updates and other emerging
services such as dynamic vehicle insurance fees, are used to illustrate the
efficacy of the proposed security architecture. We also qualitatively argue the
resilience of the architecture against common security attacks
