Abstract-Smart mobile devices are fast becoming the epicentre of people's lives. Most smart phones are currently embedded with powerful and programmable sensors such as GPS, gyroscope, microphone, camera, accelerometer etc. These sensor-enabled smart-phones would form an important element of the future networked-infrastructure. A new wave of services is bound to erupt from such connected infrastructure and smart devices that will influence all aspects of our social ecosystem. In the context of Smart Cities, this position paper and the associated invited talk presents the Mobile Technology perspective of the Smart-city architecture by presenting a conceptualized framework and highlights the open and emerging research challenges in this landscape.

Smart cities achieved digital transformation of patients' health records through the use of new technology in IoT healthcare industry. Such technologies of using IoT and remote patient monitoring systems have become dramatically fundamental to reduce the movement of patients, and hence reducing the risk of spreading Covid-19 infection. The Ministry of Health in the Kingdom of Bahrain strives to achieve digital transformation in the healthcare industry, where the National Health Information System (I-SEHA) was launched to provide higher-quality health services. The system interconnects the public healthcare institutes, allowing access to patient's data from any location without the hassle of moving the files physically. Digitization of medical data of patients and sharing some of the data with other institutions outside the protected networks may lead to major privacy and integrity concerns. This paper introduces Blockchain-based Zero-Knowledge Proof (BZKP) model, which is an IoT-based patient-centric model that fuses a zero-knowledge proof solution to be developed for protecting patient's privacy, and ensures patients prior consent on any access to their data including their health status and account balance. The proposed model is developed to provide a robust and scalable architecture for data sharing, which protects the privacy of sensitive data while maintaining high availability. It also provides strong trust and integrity of data by using the immutability features of the blockchain. BZKP is based on preapproved blockchain access tokens to address challenges of accountability and privacy in Bahrain smart cities. As a result, the model provides a secure and trusted access model between different stakeholders to share patient data while maintaining privacy, trust, and high availability. The zero-knowledge proof can be used with the smart contracts, which provides programmable actions that can be used for automating the prescriptions dispensation process for private pharmacies in a decentralized manner with high confidence. Finally, it recommends enhanced electronic key (eKey) procedures used by eGovernment of the Kingdom of Bahrain to update the smart card which stores the personal keys for protecting patient's privacy and provide better consent.
Cloud computing has created a remarkable paradigm shift in the IT industry and brought several advantages such as on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. These advantages enabled cloud to have significant impact on different sectors of smart cites. However, cloud adoption has increased the sophistication of the ever changing security risks which frustrate enterprises on expanding their on-premises infrastructure towards cloud horizons. These risks have the potential of being a major concern for smart cities due to the increasing impact of cloud on them. Managing these security risks requires adopting effective risk management method which involve both the cloud service provider and the customer. The risk management frameworks currently applied to manage enterprise IT risks do not readily fit the cloud environment and the dynamic nature of clouds, which are characterized by on demand self-service and rapid elasticity. Therefore, researchers have proposed different cloud security risk management methods and frameworks. This paper critically reviews these risk management methods and frameworks. In addition, it conducts critical analysis on two of them using qualitative content analysis technique, and evaluates their effectiveness for assessing and mitigating cloud security risks. Keywords-cloud security risk management; cloud security risk assessment; security risk management; cloud security riskI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
