Wearable fitness devices are widely used to track an individual's health and physical activities to improve the quality of health services. These devices sense a considerable amount of sensitive data processed by a centralized third party. While many researchers have thoroughly evaluated privacy issues surrounding wearable fitness trackers, no study has addressed privacy issues in trackers by giving control of the data to the user. Blockchain is an emerging technology with outstanding advantages in resolving consent management privacy concerns. As there are no fully transparent, legally compliant solutions for sharing personal fitness data, this study introduces an architecture for a human-centric, legally compliant, decentralized and dynamic consent system based on blockchain and smart contracts. Algorithms and sequence diagrams of the proposed system's activities show consent-related data flow among various agents, which are used later to prove the system's trustworthiness by formalizing the security requirements. The security properties of the proposed system were evaluated using the formal security modeling framework SeMF, which demonstrates the feasibility of the solution at an abstract level based on formal language theory. As a result, we have empirically proven that blockchain technology is suitable for mitigating the privacy issues of fitness providers by recording individuals' consent using blockchain and smart contracts.

Blockchain-enabled real-time SLA monitoring for cloud-hosted services

Cloud computing is an important technology for businesses and individual users to obtain computing resources over the Internet on-demand and flexibly. Although cloud computing has been adopted across diverse applications, the owners of time-and-performance critical applications require cloud service providers’ guarantees about their services, such as availability and response times. Service Level Agreements (SLAs) are a mechanism to communicate and enforce such guarantees typically represented as service level objectives (SLOs), and financial penalties are imposed on SLO violations. Due to delays and inaccuracies caused by manual processing, an automatic method to periodically verify SLA terms in a transparent and trustworthy manner is fundamental to effective SLA monitoring, leading to the acceptance and credibility of such service to the customers of cloud services. This paper presents a blockchain-based distributed infrastructure that leverages fundamental blockchain properties to achieve immutable and trustworthy SLA monitoring within cloud services. The paper carries out an in-depth empirical investigation for the scalability of the proposed system in order to address the challenge of transparently enforcing real-time monitoring of cloud-hosted services leveraging blockchain technology. This will enable all the stakeholders to enforce accurate execution of SLA without any imprecisions and delays by maintaining an immutable ledger publicly across blockchain network. The experimentation takes into consideration several attributes of blockchain which are critical in achieving optimum performance. The paper also investigates key characteristics of these factors and their impact to the behaviour of the system for further scaling it up under various cases for increased service utilization.

In smart home systems (SHS), devices intercommunicate to create an intelligent environment that can monitor the inhabitant's health state and provide adapted services.However, existing health monitoring systems (HMS) do not provide adapted services to the patient autonomy degree. Furthermore, in these critical systems, the Quality of Service (QoS) aspect is very important; therefore, service level agreements (SLA) are the best solution to define and guarantee the expected QoS levels, nevertheless, existing SLA specification languages lack expressiveness in terms of user preference specification, dynamic service management and pricing. In this work, we propose an elderly health state-aware SHS to offer adapted services according to the elderly health state, it is based on three main parts: (a) the functional autonomy measurement system (SMAF) for calculating the inhabitant's profile or autonomy degree, (b) domain-specific language (DSL) for SLA that aims to increase patient-awareness through the use of preferences, facilitate the SLA management using microservices, and manage the QoS dynamically using multilevel SLA (ML-SLA) concept, and (c) smart contracts for the provision of adapted services and the verification of SLA terms.
