To address these points, this article identifies all the healthcare stakeholders and translates each useful element of a patient’s electronic health record (EHR) into Fast Healthcare Interoperability Resources (FHIR), to propose a complete role-based access control model that specifies which FHIR resources an actor is allowed to access. To validate this role model, three new use cases are defined, in which the various stakeholders interact and access the FHIR resources. Moreover, specific smart contracts are detailed to implement the role model in an automated way and provide a robust access control mechanism within healthcare organizations. The feasibility of the proposed access control mechanism is demonstrated through proof-of-concept and test performance measurements.

Thus, the paper presents a comparative analysis of syntax accuracy generated for SQL databases utilizing the services of GPT-3.5 and Gemini 1.0 Pro. Firstly, the algorithms for testing GPT-3.5 and Gemini 1.0 Pro were developed. Secondly, five types of tests, which implied 700 queries, were conducted by considering requirements with low and high degrees of difficulty. The tests focus on syntax-generated accuracy using an experimental (NorthWind) database, syntax-generated accuracy study using a user-made database, syntax correction accuracy, different responses to the same question on the same account, and different responses to the same question on other accounts. The accuracy obtained for all tests revealed that the GPT-3.5 service has a value of 87 % for SQL syntax generation or correction, whereas the Gemini 1.0 Pro service has an accuracy of 80 %. These results underscore the effectiveness of GPT-3.5 and Gemini 1.0 Pro in assisting with SQL syntax tasks, albeit with differing levels of precision. The findings highlight the significance of human supervision and validation in ensuring the correctness of AI-generated responses, particularly in database-related tasks. The results affect developers and database administrators when selecting appropriate tools for query requirements.

Modern attacks incorporate a wide range of attack vectors, from social engineering to signal injection.

Regardless of the vector of a USB-based attack, the most important risks concerning most people and enterprises are service crashes and data loss. The host OS manages USB peripherals, and malicious USB peripherals, such as those infected with BadUSB, can crash a service or steal data from the OS. Although USB firewalls have been proposed to thwart malicious USB peripherals, such as USBFilter and USBGuard, their effect is limited for preventing real-world intrusions. This paper focuses on building a security framework called USBIPS within Windows OSs to defend against malicious USB peripherals. This includes major efforts to explore the nature of malicious behavior and achieve persistent protection from USB-based intrusions. Herein, we first introduce an allowlisting-based method for USB access control. We then present a behavior-based detection mechanism focusing on attacks integrated into USB peripherals. Finally, we propose a novel approach that combines cross-layer methods to build the first generic security framework that thwarts USB-based intrusions. Within a centralized threat analysis framework, the approach provides persistent protection and may detect unknown malicious behavior.

However, integrity auditing in decentralized and shared storage typically involves linear overheads, with revoked users potentially colluding with cloud providers to evade audits. To address these issues, we propose a blockchain-based multiuser data integrity auditing protocol for cognitive IoT, supporting secure user revocation and batch auditing in decentralized storage. Our protocol classifies group users into different categories and manages group users efficiently and dynamically. Besides, files stored across various storage nodes can be audited in batches and effectively updated based on novel block tags.

Clustering methods are frequently utilized in recommender systems to suggest relevant products. Fuzzy clustering techniques, one of the most commonly used clustering methods, determine the degree of relevance of each product to a cluster through the membership matrix it generates. However, determining the number of clusters in these methods poses a challenge. This study proposes an Adaptive Fuzzy C-Means Jensen Shannon (AFCM-JS) algorithm, a fuzzy and interest-based clustering method that estimates the number of clusters. The proposed AFCM-JS algorithm is implemented on an artificial dataset consisting of 6 clusters and 1000 elements. The results of the study are compared with Fuzzy C-Means (FCM), Probabilistic C-Means (PCM), and Probabilistic Fuzzy C-Means (PFCM) methods, which are fuzzy-based clustering algorithms, and the interest-based method JS. To evaluate the comparison results, 7 different cluster validity indices and an accuracy metric are employed. AFCM-JS method consistently and accurately predicted the number of clusters when tested with different maximum cluster numbers. When the clustering ability of the method is tested with cluster validity indices and the accuracy metric, AFCM-JS is found to be successful. The performance of the AFCM-JS method is tested on a dataset created for a movie recommendation system with the aim of recommending movies to users. For this purpose, movie data is weighted with a Dirichlet function for action, adventure, comedy, drama, and horror genres, creating a dataset that includes the characteristics of these 5 movie genres. The AFCM-JS method is compared with 3 different fuzzy clustering methods using 7 different cluster validity indices with this created movie dataset. Additionally, the AFCM-JS algorithm is compared with the other 3 fuzzy clustering methods based on the accuracy metric. As a result of this comparison, the AFCM-JS method achieves the highest performance among the methods with 81.9366%. Furthermore, when the performance of the proposed method is compared in terms of cluster validity indices, the AFCM-JS method successfully predicts the appropriate number of clusters and effectively groups similar movies according to their genres, accomplishing the purpose.</div></div>","PeriodicalId":50635,"journal":{"name":"Computer Standards & Interfaces","volume":"95 ","pages":"Article 104035"},"PeriodicalIF":4.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, many traditional security solutions lack adaptability to emerging technologies such as telemedicine and the Internet of Things (IoT), which introduce new attack vectors if not properly managed. To address these challenges, we introduce <strong>SMART-DEFENSE</strong> (Secure Medical Architecture for Resilient Trust and Dynamic Encryption in Federated Edge Networks with Security Enhancements), a novel defense model specifically designed for smart healthcare environments.
