With the rapid development of Internet and Internet‐based applications, accessing of the file become easy from various locations at the same time around the globe, however, maintaining of data integrity turn into a challenging issue. In order to maintain a data integrity in a large database(s), database file is being kept to secure with the presence of control policies and firewalls, which basically limit the outside users with more strict control policies. Despite these control policies, there still lies a threat to the security of the data through an insider attack. An insider attack refers to someone who is a part of the organization and can have access to the resources (network, system, etc.) with inside knowledge of the system or knows the administrative rights, and thus interferes with the data, now become one of the most critical challenging issues for the organization as such attacks are hard to notice. An insider attacker is more crucial to the organization as they can perform espionage, embezzlement, theft of the intellectual property, disclosing of the research, and development being carried out in the organization, and sabotage. Therefore, to highlight this, an Event‐Driven Data Alteration Detection technique using the tamper resistance property of Block‐chain technology is being presented in this paper. The model has been tested and found that if any unauthorized alteration in the database is being made then it can be detected using the Block‐chain Database API. To make it robust to insider attacks we have implemented and tested the model on a web‐based application. A machine learning based technique will be considered for detection in the future scope of this paper. The results obtained after experiments show the performance of the proposed architecture and the comparison outcome shows that the proposed architecture is better than related models.

“…The use of e-learning presents singularities that other teaching and learning methods do not have (Wongwuttiwat, Buraphadeja & Tantontrakul, 2020), since it was conceived as the evolution of distance education (Sathiyamoorthi, 2020;Semerci & Goularas, 2020) and is completely different from face-to-face education (Gerhatova, Perichta & Palcut, 2020). In this sense, the use of the e-learning method presents several casuistry when applied in teaching and learning processes; these characteristics include promoting conversation and interaction among students; facilitating the development of group tasks; fostering peer relationships (Bakhouyi et al, 2019); promoting collaboration among students to achieve the same goals (Sathiyamoorthi, 2020); offering communication possibilities in synchronous or asynchronous time (Gunasinghe et al, 2019); favoring learning anywhere and anytime (Krzyszkowska & Mavrommati, 2020); encouraging digital improvement (Mousavi et al, 2020); adapting to a new pace and level of learning (Mowla & Kolekar, 2020); to promote students' motivation (Rakic et al, 2020); to facilitate the progress of the ability to learn and learn at their own pace (Chaka, Nkhobo & Lephalala, 2020); so the teacher can also attend to the different peculiarities of the students (Waluyo, 2020); to provide the opportunity to reach an infinite number of pedagogical and didactic resources, which can favor and boost their learning (Mayer, 2020); to favor the continuous monitoring of the teaching and learning development by the teacher (Bheki, 2020); the teacher will make use of different digital and technological resources more familiar and friendlier to the students (Lam & Dongol, 2020).…”

The technological progress in the social field in a sudden way, specifically in the pedagogical field due to the spread of COVID-19, has had to force and use new teaching and learning strategies. As one of these many teaching processes is the method known as e-learning, which has become more valuable and very important in these times due to the rapid spread of the COVID-19 pandemic. The research method applied is descriptive, correlational, cross-sectional and predictive. The sample applied in this research is 608 students of the 5th grade of secondary education in the province of Sullana, Piura region of Peru. The results reveal the existence of a very significant influence in almost all the dimensions of the study. The dimensions with the highest association values are participation-autonomy, outcome resolution, decision concepts and decision outcomes. The dimensions with the lowest strength of association are undoubtedly the motivation rating, which can be interpreted as meaning that motivation does not have a strong influence on the results. It can be concluded that the application of the e-learning method in the teaching of 5th grade high school students in the area of mathematics is positively valued, although a strong incidence of the method on the grades is not observed, due to the fact that a lower percentage of students were unaware of the application of information and communication technologies for online learning. In addition, women tend to rate autonomy and participation more positively than men when the aforementioned teaching method is applied.

Background/Objectives: Tremendous growth of information and communication technologies (ICTs) have positively affected the field of E-Learning (EL). However, recently the education mode is shifted from the traditional classroom towards EL due to widespread COVID-19. The selection of suitable EL tool and security of EL data and environment are still the key challenges that need to be addressed. The objective of this paper is to guide the EL Practitioners in the selection of suitable EL tool and to provide a detailed framework for maintaining privacy and security of EL data and environment. Purpose: This study aims to help EL practitioners in the selection of suitable EL tool and to provide a secure framework for the security of EL data and environment. Method: Realtime statistics are gathered and analyzed to visualize the impact of COVID-19 on education around the world. The increasing demand for EL during COVID-19 is analyzed, and a detailed taxonomy is provided to make the EL practitioners aware of existing distance learning solutions. A comparison of commonly used EL tools is provided that will help in the selection of EL tools according to institutional requirements. A Blockchain-based EL framework is proposed that will help EL designer in managing the security of EL data and environment. Conclusion: The proposed framework is expected to provide a promising solution for developing a fair and open learning online education environment and will overcome the deficiencies caused by school closures during COVID-19.
