KBD-Share: Key Aggregation, Blockchain, and Differential Privacy based Secured Data Sharing for Multi-User Cloud Computing
In today's era of widespread cloud computing and data sharing, the demand for secure and privacy-preserving techniques to facilitate multi-user data sharing is rapidly increasing. However, traditional approaches struggle to effectively address the twin objectives of ensuring privacy protection while preserving the utility of shared data. This predicament holds immense significance due to the pivotal role data sharing plays in diverse domains and applications. However, it also brings about significant privacy vulnerabilities. Consequently, innovative approaches are imperative to achieve a harmonious equilibrium between the utility of shared data and the protection of privacy in scenarios involving multiple users. This paper presents KBD-Share, an innovative framework that addresses the intricacies of ensuring data security and privacy in the context of sharing data among multiple users in cloud computing environments. By seamlessly integrating key aggregation, blockchain technology, and differential privacy techniques, KBD-Share offers an efficient and robust solution to protect sensitive data while facilitating seamless sharing and utilization. Extensive experimental evaluations convincingly establish the superiority of KBD-Share in aspects of data privacy preservation and utility, outperforming existing approaches. This approach achieves the highest R2 value of 0.9969 exhibiting best data utility, essential for multi-user data sharing in diverse cloud computing applications
Applications of Federated Learning in Smart Cities: Recent Advances, Taxonomy, and Open Challenges
Federated learning plays an important role in the process of smart cities.
With the development of big data and artificial intelligence, there is a
problem of data privacy protection in this process. Federated learning is

applications and research directions of federated learning in smart cities
Federated Machine Learning
In recent times, machine gaining knowledge has transformed areas such as processer visualisation, morphological and speech identification and processing. The implementation of machine learning is frim built on data and gathering the data in confidentiality disturbing circumstances. The studying of amalgamated systems and methods is an innovative area of modern technological field that facilitates the training within models without gathering the information. As an alternative to transferring the information, clients co-operate together to train a model be only delivering weights updates to the server. While this concerning privacy is better and more adaptable in some circumstances very expensive.
This thesis generally introduces some of the fundamental theories, structural design and procedures of federated machine learning and its prospective in numerous applications. Some optimisation methods and some privacy ensuring systems like differential privacy also reviewed
Federated Learning for Medical Applications: A Taxonomy, Current Trends, Challenges, and Future Research Directions
With the advent of the IoT, AI, ML, and DL algorithms, the landscape of
data-driven medical applications has emerged as a promising avenue for
designing robust and scalable diagnostic and prognostic models from medical
data. This has gained a lot of attention from both academia and industry,
leading to significant improvements in healthcare quality. However, the
adoption of AI-driven medical applications still faces tough challenges,
including meeting security, privacy, and quality of service (QoS) standards.
Recent developments in \ac{FL} have made it possible to train complex
machine-learned models in a distributed manner and have become an active
research domain, particularly processing the medical data at the edge of the
network in a decentralized way to preserve privacy and address security
concerns. To this end, in this paper, we explore the present and future of FL
technology in medical applications where data sharing is a significant
challenge. We delve into the current research trends and their outcomes,
unravelling the complexities of designing reliable and scalable \ac{FL} models.
Our paper outlines the fundamental statistical issues in FL, tackles
device-related problems, addresses security challenges, and navigates the
complexity of privacy concerns, all while highlighting its transformative
potential in the medical field. Our study primarily focuses on medical
applications of \ac{FL}, particularly in the context of global cancer
diagnosis. We highlight the potential of FL to enable computer-aided diagnosis
tools that address this challenge with greater effectiveness than traditional
data-driven methods. We hope that this comprehensive review will serve as a
checkpoint for the field, summarizing the current state-of-the-art and
identifying open problems and future research directions.Comment: Accepted at IEEE Internet of Things Journa
