When a student excels in a course, the school rewards them with a course credential. These credentials are crucial for students when presenting their academic achievements to potential employers or government agencies for employment or further education. However, with the current reliance on computer systems to store this information, there is a risk of data theft or loss in case of device malfunctions. Obtaining government approval for these credentials is a time-consuming process, as manual verification is required to cross-reference the candidate's information with the school records. Additionally, the existing methods for preventing the creation and alteration of counterfeit graduation papers are insufficient. The use of blockchain technology in this process can address these challenges by creating a decentralized system. Blockchain ensures security through cryptographic links between blocks, and the entire chain is shared among all local nodes, making the system less vulnerable to centralization. The proposed decentralized certificate verification system incorporates essential features to create a Decentralized Application (DAPP) in the blockchain era. This design aims to streamline the verification and issuance of certificates, addressing the prevalent issue of fraudulent statements. The system is comprehensive, providing solutions for the entire Validation Issuance, Confirmation, and Certification Cycle while considering the needs of all stakeholders. © 2024 IEEE.

Training summarization models requires substantial amounts of training data. However for less resourceful languages like Hungarian, openly available models and datasets are notably scarce. To address this gap our paper introduces HunSum-2 an open-source Hungarian corpus suitable for training abstractive and extractive summarization models. The dataset is assembled from segments of the Common Crawl corpus undergoing thorough cleaning, preprocessing and deduplication. In addition to abstractive summarization we generate sentence-level labels for extractive summarization using sentence similarity. We train baseline models for both extractive and abstractive summarization using the collected dataset. To demonstrate the effectiveness of the trained models, we perform both quantitative and qualitative evaluation. Our dataset, models and code are publicly available, encouraging replication, further research, and real-world applications across various domains. © 2024, CC BY.

Phishing is a cyber threat where attackers create deceptive websites or emails to exploit individuals for fraudulent purposes such as providing sensitive information like usernames, passwords, or financial details. Hence, detecting phishing emails is of paramount importance to protect sensitive information, preventing financial losses, protecting against identity theft, and maintaining trust. This study employs machine learning techniques to classify and categorize websites that are used for phishing attacks. To achieve this, we proposed a classification model for the detection of phishing domains based on classification rules. These rules were formulated based on analyzing and distributing them into three classifiers: domain name features, search engine opinion (SEO) information of the domain, and security scans by security vendors. A total of eleven classification rules were formulated which were distributed as follows: six rules for the first classifier, four rules for the second classifier, and one rule for the third classifier. Each classifier feeds its results to the main classifier, which then evaluates the received results based on its rules. Domain names from 222 confirmed phishing URLs were used to test the suggested model. The model demonstrated exceptional performance, achieving an impressive accuracy rate of 99.1% during testing. © 2023 IEEE.

When learning from instructional videos, students frequently take handwritten notes to improve recall and comprehension. When reviewing their notes, it can be difficult to return to the corresponding part of the video. In this paper, we present NoteLink, a mobile application that allows students to take pictures of their notes to re-find and play relevant videos on their smartphone or tablet. Our study followed four phases. In Phase I, we identified the characteristics of students' notes by analyzing 10 engineering students' handwritten notes taken while watching instructional videos. We found: 1) students' notes are comprised of four content types: text, formula, drawing, and a hybrid of two or more types, 2) at least 75% of the notes, regardless of content type, manifest some degree of verbatim overlap with the corresponding video content, and 3) videos are referenced at three scales of temporal granularity: point, interval, and whole video. In Phase II, we designed a prototype mobile application, NoteLink, that retrieves instructional videos that are similar to students' notes. In Phase III, we ran a usability study with 12 engineering students to evaluate their preferences for the temporal granularity of retrieved videos and how search results are displayed. Students reported a preference for matches at the interval temporal granularity. Interviews with participants suggest that NoteLink-like tools for re-finding instructional videos are useful. In Phase IV, we evaluated the retrieval accuracy of NoteLink using the data collected in Phase I. The overall accuracy was 78%, and 98% for textual notes. We also provide design recommendations for optimizing NoteLink.

In our digitalized world and under the economic pressure of competition, every company must react flexibly to opportunities and problems that arise. One way to cope with these challenges is to use web-based Enterprise Resource Planning (ERP) or Customer Relationship Management (CRM) Systems, which provide significant functionality inside their system range. Third-party systems often have to be integrated with ERP or CRM systems but cannot be connected, for instance, because of limited Application Programming Interfaces (API) or data structures. Therefore, such tasks are complex and time-consuming and must be done by software engineers, who are limited resources in today's enterprise context. However, HTML documents can be integrated with web-based systems such as ERP or CRM, and HTML creation is not limited to the software engineering workforce. Our low-code environment, which is based on W3C web components standards and RESTful web services with state-of-the-art authentication approaches, could solve the shortage because we empower business developers to embed dynamic database content declaratively in static HTML pages or web-based systems such as WordPress or SoftEngine ERP-Suite. Our system also allows the declarative integration of forms for creating/modifying and deleting data records (CRUD functionality). The low-code web components access the database via the RESTful service. The API of the RESTful service abstracts the database manufacturerspecific characteristics, such as the storage format of the metadata. Copyright © 2024 by SCITEPRESS.

In this paper, we study a generalized quasi-variational inequality (GQVI for short) with twomultivalued operators and two bifunctions in a Banach space setting. A coupling of the Tychonov fixedpoint principle and the Katutani-Ky Fan theorem for multivalued maps is employed to prove a new existencetheorem for the GQVI. We also study a nonlinear optimal control problem driven by the GQVI and givesufficient conditions ensuring the existence of an optimal control. Finally, we illustrate the applicability of thetheoretical results in the study of a complicated Oseen problem for non-Newtonian fluids with a nonmonotone andmultivalued slip boundary condition (i.e., a generalized friction constitutive law), a generalized leak boundarycondition, a unilateral contact condition of Signorini’s type and an implicit obstacle effect, in which themultivalued slip boundary condition is described by the generalized Clarke subgradient, and the leak boundarycondition is formulated by the convex subdifferential operator for a convex superpotential.

The problem of efficiently covering an area with a limited number of sensors or cameras is an important research topic in various fields such as surveillance, monitoring, and inspection. This problem can be posed as a Traveling Salesman Problem (TSP), where the optimal path needs to be found to visit all the coverage points and return to the starting point. However, the computational complexity of solving TSP increases exponentially with the number of coverage points, making it impractical for large-scale applications. This paper proposes a novel approach to solving the coverage problem as a TSP by incorporating tree selection algorithms to improve efficiency and accuracy. The proposed approach represents the study area as a graph, with each node representing a coverage point and the edges representing the distance between them. To reduce computational complexity, we use various tree selection algorithms to select the best possible starting point for the TSP algorithm. To evaluate the effectiveness of the proposed approach, we conduct simulations using different scenarios with varying numbers of coverage points. The simulation results demonstrate that the proposed approach significantly improves the quality of coverage while reducing computational complexity compared to traditional TSP algorithms. Moreover, the proposed approach can be applied in a wide range of real-world applications, such as surveillance, monitoring, or inspection, where efficient and accurate coverage of an area is essential. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The denial of service (DoS) attack has evolved into one of the most serious security threats on the Internet, aimed at preventing a service from being available. To launch a distributed denial of service (DDoS) attack, a group of compromised machines is used. This paper discusses and analyzes certain flooding-based DoS attacks, which flood a network or a specific system inside a network with unwelcome traffic, in addition to a discussion of the classification of DDoS defense mechanisms, and countermeasures and presenting a comparison of selected Flood-DoS attacks mitigation algorithms. Finally, we explore the severity of distinct DoS attacks by comparing each attack type to a set of criteria and highlighting some of the future research directions. © 2022 IEEE.
