ABSTRACT

Information system security is of paramount importance to every institution that deals with digital information. Nowadays, efforts to address cybersecurity issues are mostly software or hardware-oriented. However, the most common types of cybersecurity breaches happen as a result of unintentional human errors also known as end user errors. Thus, this study aimed to identify the end-user errors and the resulting vulnerabilities that could affect the system security requirements, the CIA triad of information assets. The study further present state-of-the-art countermeasures and intellectual ideas on how entities can protect themselves from advent events. Adopted is a mixed-method research approach to inform the study. A closed-ended questionnaire and a semi-structured interview were used as data collection tools. The findings of this study revealed that system end user errors remain the biggest threat to information systems security. Indeed errors make information systems vulnerable to certain cybersecurity attacks and when exploited puts legitimate users at risk.

Xiangyu Xu and Jianfei Peng, College of Computer Science and Technology, Nanjing University of Aeronautics and Astronautics, Nanjing, China

ABSTRACT

The smart city is an emerging notion that leveraging the technique of Internet of Things (IoT) to achieve more comfortable, smart and controllable cities. The communications crossing domains between smart cities is indispensable to enhance collaborations. However, crossing-domain communications are more vulnerable since there are in different domains. Moreover, there are huge different devices with different computation capabilities, from sensors to the cloud servers. In this paper, we propose a lightweight twolayer blockchain mechanism for reliable crossing-domain communication in smart cities. Our mechanism provides a reliable communication mechanism for data sharing and communication between smart cities. We defined a two-layer blockchain structure for the communications inner and between smart cities to achieve reliable communications. We present a new block structure for the lightweight IoT devices. Moreover, we present a reputation-based multi-weight consensus protocol in order to achieve efficient communication while resistant to the nodes collusion attack for the proposed blockchain system. We also conduct a secure analysis to demonstrate the security of the proposed scheme. Finally, performance evaluation shows that our scheme is efficient and practical.

Privacy as invisibility (by default) Bridging the gap between anarcho-capitalists and cypherpunks

Andrea Togni, Independent researcher (PhD in philosophy), Italy

ABSTRACT

The main thesis of this paper in political philosophy is that privacy as invisibility (by default) is one of the best weapons to defend property rights. Privacy is not something that can be owned, but it is a necessary condition for the preservation of property. Physical and tangible objects behave differently from information, ideas and data with regard to property and privacy: while ownership of the latter is lost as soon as they are seen by adversaries, this is not the case for the former. In both cases, however, making property invisible is crucial to keep it safe. This paper tries to point out why attaining privacy as invisibility is a prerequisite for any free society. In the first paragraph, I recollect some of the main theories on privacy, so that the discussion is contextualized properly. Then, I provide some conceptual clarifications useful to better understand the purpose of this work. In the third section, I address the question why the private sector has not been successful in replacing governments despite being able to provide better services at better prices. Last, I discuss the concept of privacy as invisibility with a special consideration for the digital realm, and in doing so I call for a structural alliance between anarchocapitalists and cypherpunks. To paraphrase Rothbard: the cypherpunk ethos is the fullest expression of anarcho-capitalism, and anarcho-capitalism is the fullest expression of the cypherpunk ethos.

Redefining the Data Protection Impact Assessment Methodology to Support the Requirements of the General Protection Regulation in a Big Data Analytics Context – A Delphi Study Approach

Georgios Georgiadis and Geert Poels, Faculty of Economics and Business Administration, Ghent University, Belgium

ABSTRACT

Big Data Analytics (BDA) is a complex ecosystem comprising users, high-capacity infrastructure, services, and applications that store, retrieve, and process large amounts of data from widely scattered sources. Because of their benefits, like in the case of suppressing the spread of COVID-19, there is growing interest from companies and organisations in investing in such technologies. There are, however, several mounting concerns associated with the secure and lawful processing of personal data under the General Data Protection Regulation (GDPR) and whether privacy and data protection risks associated with the overall data handling could be adequately assessed using the Data Protection Impact Assessment (DPIA). In this position paper, we describe our research work in addressing those concerns and our imminent research plan that will lead to the development of an improved DPIA methodology capable of assessing the data protection risks inherent in projects relying on BDA technologies.

Database Security in a Dynamic IT World (Examine Database Security Fundamentals that Help to make sure High Levels of Flexibility in Data Use, and Effectiveness in Data Protection)

Temitope-Awodiji, California Miramar University, USA

ABSTRACT

Databases are vulnerable. Public statements by Target, Home Depot, and Anthem following their extremely advertised data breaches are each uniform and succinct on how their breaches unfolded: unauthorized access to those systems that ultimately led to the extraction of sensitive information. A comprehensive strategy to secure a database is over data security. Usually, security events will be related to the later action: illegitimate access to data confidentiality damage, injury to the integrity of knowledge, loss of data accessibility (Discover). Loss of privacy of data, creating them accessible to others without a right of access is not visible within the database and does not need changes deductible database. This paper addresses these events to confirm database security.

Hadoop Mapreduce as a General Framework for Mining Small Patterns

Ishak H.A MEDDAH, LabRi Laboratory, Ecole Superieure en Informatique Sidi Bel Abbes, Algeria

ABSTRACT

Hadoop MapReduce is an open solution for the big data treatment, it’s used to analyse and process a set of voluminous data. his happens by distributing the computational work across a cluster of virtual servers running in a cloud or a large set of machines. Process Mining provides an important bridge between data mining and business process analysis. Its techniques allow for extracting information from event logs. Generally, there are two steps in process mining, correlation definition or discovery and the inference or composition. First of all, our work consists to mine small patterns from a log traces. Those patterns are the representation of the traces execution from a log file of a business process. In this step, we use existing techniques. The patterns are represented by finite state automaton or their regular expression; and the final model is the combination of only two types of different patterns represented by regular expressions. Second, we compute these patterns in parallel, and then combine those small patterns using the Hadoop framework. We have two steps; the first is the Map Step through which we mine patterns from execution traces, and the second one is the combination of these small patterns as a reduce step.

Learning Styles as a Referential Framework for Classifying Learners who learn online

Pengiran Shaiffadzillah Pengiran Omarali, Educational Technology Centre, Brunei Darussalam

ABSTRACT

Over the last two decades, the online learner demographic is predominantly attributed to higher education students who undertake formal online learning courses from institutions all over the world. Coming from different backgrounds, these learners collectively comprise of already diverse and heterogeneous groups of individuals with different dispositions toward learning in general and learning online or in blended learning environments. More recently however, and abruptly augmented further by the global Covid-19 pandemic, online learning and blended learning have been introduced into K-12 learning. With the higher education online learner demographic being diverse in online learning preferences as it is, the more dynamic profiles of learners in K-12 demand education providers the capacity to identify learners using different types of taxonomies and learner constructs so that their learning environments, whether it be fully online or blended, can supplement if not replicate the teaching and learning that occur in the on-site classrooms. One such construct is ‘learning styles’. This article is a review of learning styles used as a referential framework in the practice of online learner classification, taking into consideration arguments from different perspectives of the Learning Styles discourse including studies that have found evidence in support of learning styles, studies that have found no relationship between learning styles and learning effectiveness, and commentaries by researchers who have questioned the significance of learning styles itself.

A Case Study of Integrating Audio-Visual Aids into English Language Teaching in Indonesian Junior High Schools: A Multiliteracies Pedagogical approach

Salwa, The University of Newcastle Australia

ABSTRACT

With the implementation of the current 2013 curriculum in Indonesian secondary education, the use of multimedia and technology as New Literacies is promoted. The practice of adopting a Multiliteracies Pedagogical approach has become increasingly prominent. Drawing on the framework of Multiliteracies practices which incorporates the four components of situated practice, overt instruction, critical framing, and transformed practice (New London Group,1996), this article presents the findings of a descriptive case study investigating teachers’ perceptions of the use of Audio Visual Aids in English language teaching in Indonesian Junior high schools. Data was collected from semi-structured interviews, focus group discussions and classroom observations with four English teachers, four students’ focus group discussions from four different types of schools. Thematic analysis was used in analysing the qualitative data. The findings indicated that most teachers frequently applied Multiliteracies Pedagogy which focuses on the use of Multimodality in their English language teaching by integrating Audio-Visual materials into their English language teaching. The findings also indicated that the teachers’ enactment in applying the four multiliteracies framework aspects, the situated practice and overt instruction were mostly applied whereas critical framing and transformed practice were not dominantly used. Given that fact, promoting Audio-Visual materials in preservice teachers’ training and teacher professional development training in Indonesian Junior High schools is recommended.

An Intelligent and Data Driven Mobile Platform for Early Childhood Development using Machine Learning and Data Mining

Maggie Ding¹ and Yu Sun², ¹Orange County School of the Arts, Santa Ana, CA 92701, ²California State Polytechnic University, Pomona, CA, 91768

ABSTRACT

In China almost 96 million children live in rural areas. Some of these children suffer from malnutrition since parents or guardians do not have knowledge of nutritional plans or how to calculate nutritional values. However, most of the Chinese population has access to a mobile device. This paper proposes a mobile application, which runs on the IOS and Android platforms, to calculate nutritional values and recommend a nutritional menu. EZ Nutrition and Education is a mobile app that targets millions of parents and caregivers in rural China and provides a solution to the regions’ early childhood underdevelopment problems. It provides recommendations for healthy meals and age-appropriate educational activities, measures children’s daily intake of calories and macro-nutrients (protein, carbs, and fats), and provides a way to have fun through activities that teach skills and values so as to prevent the underdevelopment of rural children’s physical, intellectual and mental growth. We applied our application to a group of participants (ages 6-12) and conducted a qualitative evaluation of the approach. The results show that the nutritional calculator feature can help parents improve the nutritional health of their children. Though two of the underweight participants lost weight and two of the overweight participants gained weight while using the recommended nutritional plan, we believe that the recommended nutritional menu could be an excellent feature for this application after we adjust some of the parameters since some parents claimed they could not follow the recommended menus.

Fencingestimate: A 3D Game-Based Interactive Driving Simulation Training System Using Artificial Intelligence and Computer Vision

Weixuan Lei¹ and Yu Sun², ¹Irvine, CA 92604, ²California State Polytechnic University, Pomona, CA, 91768

ABSTRACT

Training for fencing during the pandemic has changed from what it was beforehand. Students have been taking lessons online, and instead of fencing with peers, students now train by watching and analyzing fencing videos. Learning fencing from watching videos of world class fencers is an effective way of learning. However, sabre fencing is so fast that many inexperienced fencers are unable to capture the important information by watching short clips. Therefore, they are unable to learn techniques such as sabre fencing just from watching videos. This paper traces the development of an application that can utilize computer vision and pose estimation to analyze fencing video clips and output accurate scored points as well as the techniques used within the given clips. We applied our application to help less experienced fencers improve their ability to recognize points and conduct qualitative evaluations of different fencing techniques.

Curriculum Semantic Retrieval System based on Distant Supervision

Qingwen Tian, Shixing Zhou, Jianxia Chen, Yi Gao and Shuijing Zhang, School of computer science, Hubei University of Technology, Hubei, China

ABSTRACT

Knowledge Graph is a semantic network that reveals the relationship between entities, which construction is to describe various entities, concepts and their relationships in the real world. Since knowledge graph can effectively reveal the relationship between the different knowledge items, it has been widely utilized in the intelligent education. In particular, relation extraction is the critical part of knowledge graph and plays a very important role in the construction of knowledge graph. According to the different magnitude of data labeling , entity relationship extraction tasks of deep learning can be divided into two categories: supervised and distant supervised. Supervised learning approaches can extract effective entity relationships. However, these approaches rely on labeled data heavily resulting in the time-consuming and labor-consuming. The distant supervision approach is widely concerned by researchers because it can generate the entity relation extraction automatically. However, the development and application of the distant supervised approach has been seriously hindered due to the noises, lack of information and disequilibrium in the relation extraction tasks. Inspired by the above analysis, the paper proposes a novel curriculum points relationship extraction model based on the distant supervision. In particular, firstly the research of the distant supervised relationship extraction model based on the sentence bag attention mechanism to extract the relationship of curriculum points. Secondly, the research of knowledge graph construction based on the knowledge ontology. Thirdly, the development of curriculum semantic retrieval platform based on Web. Compared with the existing advanced models, the AUC of this system is increased by 14.2%; At the same time, taking "big data processing" course in computer field as an example, the relationship extraction result with F1 value of 88.1% is realized. The experimental results show that the proposed model provides an effective solution for the development and application of knowledge graph in the field of intelligent education.

ABSTRACT

The issue of cell-to-cell interferences is a serious problem that has always been raised in digital communication system such as NR. The communication method of NR and LTE is OFDM. OFDM has many advantages, but has fatal disadvantage called ICI(Inter-Cell Interference) because resources among cells are overlapped always. For example, NR’s typical interferences are ICIs among PDSCH(Physical Downlink Shared Channel), PDCCH(Physical Downlink Control Channel), PUSCH(Physical Uplink Shared Channel), PUCCH(Physical Uplink Control Channel, CSI-RS(Channel State Information-Reference Signal) and SRS(Sounding Reference Signal). Among them, it is important to determine the correct beamforming weight factor value by estimating the channel with SRS. Therefore, the ICI of SRS degrades the performance of downlink throughput. This paper analyses the impact of SRS’s ICI in conventional scheme, introduces the proposed AC-CS(Auto-Correlation Cyclic Shift) schemes by the Zadoff-Chu sequence to overcome the ICI of SRS and analyses theirs performance. The method used for performance analysis is determined by the detection abilities, which are missing probability and false alarm probability.

ABSTRACT

One of the issues that many judicial and security authorities are concerned about is the speech accuracy confirmation. All of the designed lie detection systems have not been able to confirm the speech accuracy completely. These methods include sound stress measurement, thermal imaging, and deception detection which use blinking. The drawback of the above methods is that they are costly, and difficult to registration, analysis and interpretation. According to the results of various experiments on polygraph data, Photo Plethysmography signals and skin electrical resistance are mostly depend on mental states, especially stress. Also, the variations of these signals have the most weight in the general conclusion of the parameters changes. In this paper, lie detection data recorded at the Intelligent Signal Processing Research Institute were used to show that the ELMAN classifier has a proper percentage of accuracy.

ABSTRACT

This paper presents an analysis of the performance of popular convolutional neural network (CNN) architectures on Image Recognition. The performances of different types of CNN’s are compared on a single dataset. The CNN’s are already pre-trained on imagenet data, so their performances will give a measure of which type of CNN to use for quick fine tuning with greater accuracy. This study focuses on analysing the performance of four popular networks: Alex Net, VGGNet, Inception and ResNet50. Four different CNN’s are taken and fine tuned them on furniture images. The analysis shows that ResNet50 and Inception are able to recognize objects with much better accuracy than AlexNet and VGG16 with less number of epochs.

Seyed Ali Hosseini and Karim Salahshoor, Department of Automation and Instrumentation Engineering Petroleum University of Technology Ahwaz, Iran

ABSTRACT

Systems are continually subjected to faults or malfunctions because of age or sudden events, which might degrade the operation performance and even result in operation failure that is a quite important issue in safety-critical systems. Thus, this vital problem is the main reason to use the Fault-Tolerant strategy to improve the performance of the system with the presence of faults. A fascinating property in Fault-Tolerant Controllers (FTCs) is adaptability to system changes as they evolve throughout system operations. In this paper, a Q-learning algorithm with greedy policy is used to realize the FTC adaptability. Then, some fault scenarios are introduced in a Continuous Stirred Tank Reactor (CSTR) to compare closed-loop performance of the developed Q-learning based FTC with respect to conventional PID controller and a RL-based FTC. The obtained results show the effectiveness of Q-learning-based FTC in different fault scenarios.
