A Novel Approach for Improving the Security of IoT–Medical Data Systems Using an Enhanced Dynamic Bayesian Network

Abstract

IoT (Internet of Things) devices are increasingly being used in healthcare to collect and transmit patient data, which can improve patient outcomes and reduce costs. However, this also creates new challenges for data security and privacy. Thus, the major demand for secure and efficient data-sharing solutions has prompted significant attention due to the increasing volume of shared sensor data. Leveraging a data-fusion-based paradigm within the realm of IoT-protected healthcare systems enabled the collection and analysis of patient data from diverse sources, encompassing medical devices, electronic health records (EHRs), and wearables. This innovative approach holds the potential to yield immediate benefits in terms of enhancing patient care, including more precise diagnoses and treatment plans. It empowers healthcare professionals to devise personalized treatment regimens by amalgamating data from multiple origins. Moreover, it has the capacity to alleviate financial burdens, elevate healthcare outcomes, and augment patient satisfaction. Furthermore, this concept extends to fortifying patient records against unauthorized access and potential misuse. In this study, we propose a novel approach for secure transmission of healthcare data, amalgamating the improved context-aware data-fusion method with an emotional-intelligence-inspired enhanced dynamic Bayesian network (EDBN). The findings indicated that F1 score, accuracy, precision, recall, and ROC-AUC score using DCNN were 89.3%, 87.4%, 91.4%, 92.1%, and 0.56, respectively, which was second-highest to the proposed method. On the other hand, the F1 score, accuracy, precision, recall, and ROC-AUC scores of FRCNN and CNN were low in accuracy at 83.2% and 84.3%, respectively. Our experimental investigation demonstrated superior performance compared with existing methods, as evidenced by various performance metrics, including recall, precision, F measures, and accuracy.

With highlights like range, surface, and region, it gives significant insights into cell attributes [15]. The dataset distinguishes between dangerous and harmless cases, aiding in disease finding.…”

Secure Healthcare Model Using Multi-Step Deep Q Learning Network in Internet of Things

“…In [30], the author discusses the deep Q learning based neural network with a privacy preservation method, DQNNPP. In this a model for secure transmission of healthcare data, known as EDBN-Enhanced Dynamic Bayesian Network-is discussed [31]. In [32], a demonstration of IoT architecture based on improving the deep learning model known as YOLO-You Only Look Once-for providing security is given.…”

Using Learning Focal Point Algorithm to Classify Emotional Intelligence

“…This research undertakes the formidable challenge of seamlessly integrating emotional intelligence into the fabric of robot teachers, with a deliberate emphasis on the significance of understanding and appropriately responding to students' emotions. By doing so, it seeks to enhance the effectiveness of the teaching and learning experience, recognizing that the emotional context within the educational setting plays a crucial role in shaping the overall success of the educational process [6], [7], [8], [9].…”
