    Get PDF
    In the World of AI in Healthcare, coupling Federated Learning (FL) with Blockchain is a changing paradigm in building secure and privacy upholding AI systems. However, FL potentially can be subject to model poisoning attacks and has no mechanisms for integrity verification of local models. This paper presents a blockchain-based federated learning framework with Secure Multi-Party Computation for the verification of encrypted models. Prior to aggregation, local model validation takes place under privacy preservation to ensure no malicious updates are counted. Verified models are then stored and SMPC aggregation on the blockchain to enable tamperproof decentralized training. The updated global model is shared among participants via the blockchain ledger. Experimental evaluations using Convolutional Neural Networks (CNNs) on medical datasets show that the proposed system can eliminate all poisoned models, improving global model accuracy from 0 to potentially 25%, while the verification speed is still close to normal inference. This framework promotes trust, data privacy, and model integrity in collaborative healthcare AI

    The Rise of Artificial Intelligence in Intellectual Property Law: Patentability and Copyright Issues

    Get PDF
    The rise of Artificial Intelligence (AI) is transforming and posing important challenges in the field of Intellectual Property (IP) law regarding patentability and copyright. As AI systems increasingly produce inventions and creative works without human involvement, doubts arise on how suitable the present framework of intellectual property rights-invented to protect human-made innovations-is for such a confused state of AI. This paper develops its line of analysis around the AI implications for patent and copyright laws, checking out if current legal structures are such that they can address outputs from AI systems. While current laws in the patent regime recognize only a human inventor, an AI system can produce novel and non- obvious inventions. Should AI be viewed as an inventor, or would patent laws be transformed to recognize that AI is merely a tool in the invention process? The paper discusses various in-applicable case law and decisions such as the 2019 ruling of the USPTO that in certain inventions, the inventor could only be a human being, which manifests the fact that patentability frameworks remain unfit for AI-generated inventions. Moreover, in relation to copyright, it can be noted that the contingent works executed by AI challenge and suspend the necessity for human authorship. When AI generates such works on its way, the alternative arises and must be critically analysed who is to be considered the actual owner of copyright over the work? Current copyright frameworks in various jurisdictions, such as the U.S., do not extend protection to AI-generated works without incorporation of some human involvement in their creation. Possible suggestions of reform like placing authorship over X work under the AIs developer or user, or a New IP category addressing the input of AI in creation, formulations were discussed in the paper. Ultimately, innovations in both patent and copyright laws ought to grow in a balanced way that, while producing adequate protective layers over human creators, prepares itself to come into terms with rising Aid creativity and invention. For maintaining justice and fairness, reform in legal constructs for tracking with AI-generated creations is inevitable

    Context-Aware Anomaly Detection In Smart Cities Using Multi-Modal Machine Learning Approaches

    Get PDF
    Anomaly detection in smart cities is crucial for identifying unusual patterns in real-time data streams generated by diverse urban systems, such as traffic flow, energy consumption, air quality, and public safety. This study proposes a multi-modal machine learning framework for context-aware anomaly detection, integrating Convolutional Neural Networks (CNNs) for spatial feature extraction, Long Short-Term Memory (LSTM) networks for temporal pattern recognition, and contextual data (e.g., weather, public events) to improve detection accuracy. The hybrid CNN-LSTM model captures both spatial and temporal dependencies. At the same time, the inclusion of contextual information enables the model to adapt to changing conditions, improving the detection of anomalies such as traffic accidents or pollution spikes. Experimental results demonstrate that the proposed framework outperforms traditional anomaly detection methods in terms of accuracy, precision, and recall. The hybrid model's superior performance highlights its potential for real-time applications in smart cities, including sustainable urban management, fraud detection, and public safety monitoring

    Estimation Of Binary Logistic Regression Parameters In Sensitive Surveys For A Two-Stage Randomized Response Technique

    Get PDF
    When collecting data on sensitive topics such as abortion, harassment, tax evasion, and income, respondents often provide untruthful answers, leading to biased results. To address this issue, Warner introduced the Randomized Response Technique (RRT) to obtain sensitive information while ensuring respondent privacy. Building on this, Narjis and Shabbir proposed a two-stage RRT to estimate the prevalence of a sensitive attribute. This study extends their two-stage RRT by incorporating covariates through logistic regression to analyze their effect on the sensitive characteristic. Parameters of the logistic regression model are estimated under simple random sampling, and the performance of maximum likelihood estimators is evaluated through simulation

    Blockchain For Higher Education Reform: A Strategic Model For Formalizing Knowledge, Advancement, And Governance Systems

    Get PDF
    Universities across post-transition and semi-formal education systems face a persistent paradox: while knowledge production lies at the heart of their mission, the structures guiding staff advancement, knowledge use, and internal governance remain informal, politicized, and resistant to change. This paper presents a strategic reform model that uses blockchain not as a digital overhaul, but as a trust-enabling backbone to support cultural and institutional formalization. Grounded in prior field research and lived insight into Eastern European academic environments, the model integrates blockchain infrastructure with knowledge management formalization and performance accountability. It offers a layered blueprint to address deep-rooted challenges such as misaligned strategic plans, opaque staff progression, fragmented budgeting, and siloed information systems. Each layer maps onto essential university functions—rectorate governance, HR, finance, research, international relations, and IT—while allowing phased, modular implementation rooted in organizational realism. Rather than replacing the culture, the design respects it, while offering scalable tools for traceable decisions, transparent recognition, and shared institutional memory. By linking strategy, governance, and knowledge in practical and culturally aware ways, this model offers a path toward universities that are not only better managed—but more transparent, future-ready, and self-aware
