Transformation of the healthcare sector through the adoption of IoMT devices offers significant benefits, including efficient and timely medical interventions based on real-time monitoring of patients’ vitals. Security, authentication and privacy safeguards are the key hurdles in adopting medical-grade IoMT deployment. To address these critical hurdles, a lightweight, efficient and reliable key exchange scheme, termed iSecureHealth, has been proposed. The proposed system incorporates a security control node outside the User-IoMT-Gateway paradigm to enforce end-to-end secure data transactions for a medical-grade IoMT-based patient monitoring Environment. The secure data transaction techniques and key management comprise an authentication, authorization, and access (AAA) control layer, ensuring a secure data channel between IoMT sensors and the Gateway node (GNo) paradigm. Elliptic Curve Cryptography (ECC)-based key management, using the Elliptic Curve Diffie–Hellman Key Exchange technique, provides a secure, end-to-end private health data transmission through authorized IoMT devices. We used HMACSHA256 for JWT session key generation to design a lightweight automatic authentication scheme for iSecureHealth. For mutual authentication validation, a well-known BAN-Logic is applied. We considered the widely accepted random Oracle-based Real-Or-Random (ROR) model and Dolev–Yao (DY) logic for formal and informal security analysis, respectively. A generic ESP32/ESP-32S development board connected with a multisensory (MAX30102) was used for implementation. The publisher–subscriber-based lightweight Secure Message Queuing Telemetry Transport (SMQTT) protocol demonstrates real-time streaming of sensor-acquired data over the secure transport layer. Our experiments and results show that the performance of the proposed technique is better compared to the baselines.</p></div>","PeriodicalId":37151,"journal":{"name":"Smart Health","volume":"33 ","pages":"Article 100504"},"PeriodicalIF":0.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141953185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray images are frequently observed manually to find out the existence of pneumonia in a patient’s body. However, diagnosing pneumonia using X-ray images through manual observation by different health professionals may lead to different conclusions. Thus, an efficient autonomic system is required to diagnose pneumonia from X-ray images, and deep learning techniques, such as CNN-based approaches are frequently used to create such autonomy. To ease the process of pneumonia diagnosis, in this study, we have proposed the SE-MobileNet approach. We compared the performance of the proposed SE-MobileNet with the default version of MobileNetV2 integrated with transfer learning. Using the publicly available Kaggle dataset, it is observed that SE-MobileNet obtained 97.4% accuracy on a select test set against the 96.4% accuracy of MobileNetV2, and in 10-fold cross-validation, SE-MobileNet achieved an average of 95.92% accuracy against the 92.35% accuracy of MobileNetV2. Further comparison analysis proves that the SE-MobileNet model not only performs much better than the vanilla MobileNetV2 but also performs competitively against the literature. In addition, robustness evaluation has been introduced in this study where Fast Gradient Sign Method (FGSM) is performed to generate adversarial images. It is found that in robustness evaluation, SE-MobileNet also performs better compared to MobileNetV2. Finally, to validate the appropriateness of the learning of the model, Explainable AI (XAI) based techniques have been employed.</p></div>","PeriodicalId":37151,"journal":{"name":"Smart Health","volume":"33 ","pages":"Article 100500"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141325545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
