Reducing the Digital Divide by using Cloud Computing – A focus on Education.

Cloud computing is a hot technology now, is a new business model. The use of cloud computing to businesses in many industries, especially e-commerce has brought new opportunities, However, due to the characteristics of its own cloud computing and the Internet network security flaws, Resulting in e-commerce system security weaknesses. This paper describes the cloud computing and security issues of cloud computing in the e-commerce, Through e-commerce security needs analysis, Proposed ensuring e-commerce security methods in the cloud.

Despite the promising application of cloud computing within government organisations, determining the barriers to the successful implementation of cloud computing remains a major challenge. Often, government organisations face formidable barriers to fully adopting cloud computing functions. These barriers include organisational culture issues, a weak application of service-level agreements (SLAs), compliance issues, interoperability and integration issues, the lack of an organisational strategy, cost calculation methods, cloud service availability, and cloud data security and privacy, as well as insufficient trust in providers. Tackling these barriers while meeting the specifications of government cloud computing involves architectural requirements and mechanisms. In addition, the nature of cloud ecosystem operation and its alignment with appropriate strategies are known to be complex, also considering the growing desire for governance solutions. Although researchers and organisations have recognised cloud computing obstacles prior to the cloud implementation stage, fewer efforts have been made to investigate cloud barriers in-depth during and after cloud implementation projects or when introducing governance solutions. This might partly be attributable to inadequate enterprise requirements for addressing cloud barriers, the complexity of government cloud specifications, and the lack of involvement by cloud stakeholders, such as providers and consumers. Thus, the aim of this dissertation is to develop a governance method consisting of the generation and testing of architectural requirements to overcome dominant cloud barriers and improve cloud computing functionalities in the implementation stage. To achieve this, the roles of related cloud providers and consumers have been investigated. The study was guided by activities of The Open Group Architecture Framework (TOGAF) Architecture Development Method (ADM) to design related architectural requirements that would provide best practices for the development of the governance method. Using a sequential, exploratory mixed method, multiple qualitative case studies on the role of cloud providers were conducted to explore which and how architectural requirements are suitable and applicable for addressing the identified cloud barriers. Afterwards, a quantitative survey study was performed to examine and validate the findings from the qualitative phase and to discover the role of cloud consumers in tackling cloud barriers. The utilisation of dual perspectives, from cloud providers and consumers, to design and measure the suitability and applicability of the architectural requirements is a substantial theoretical contribution in the field of enterprise information systems and cloud governance. Both cloud providers and consumers in the selected research context balanced their roles in the composition of cloud ecosystem projects, reducing complexity and enabling cooperative solutions for handling cloud barriers with different levels of emphasis and prioritisation. The results of this thesis provide significant guidance in eliciting architectural requirements as well as in their successful contribution to addressing the 10 identified cloud barriers in the selected context. Seeking a cloud provider’s perspective through multiple case studies resulted in 24 confirmed, newly emerged architectural requirements and 48 sub-requirements for best practices to support Information Technology (IT) managers and practitioners during the implementation of government cloud projects. From the point of view of the cloud service consumer, statistical evidence showed that the architectural requirements proved to be relevant and applicable and resulted in the validation of only eight important cloud constructs with a scale of 36 architectural requirements. The results at the governance level also produced a clear method that can enhance the realisation of value when business/IT strategies and EA governance practices both take place in cloud projects. The governance method also consists of a set of architectural requirements to support managing and controlling cloud computing implementation projects with related stakeholders and change management initiatives. The architectural requirements have been modelled via the ArchiMate 3.0 modelling language as unique and beneficial contributions for the enhancement of enterprise architecture practices. This thesis thereby introduces a novel cloud governance method with clear mechanisms and practices to serve as crucial resources for related organisations, decision-makers, business practitioners and researchers.

Digital Divide means there is a gap between information and communication technology(ICT) of different objects. ICT is classified two types, traditional ICT and emerging ICT. Using time series data analyze influence factors. Results show degree of urbanization, education attainment, level of developing economy, degree of trade openness vary in degree during different stages of ICT diffusion. Moreover, at the same stage, traditional ICT and emerging ICT are affected by different factors. So making a different between them, we could close gap.

Information and Communication Technologies (ICTs) are of great importance in today’s society and have permeated different aspects of human life. In fact, access to them is now considered a fundamental right. There exists, however, a gap between individuals and populations who have access to these technologies and those who do not, which has led to social exclusion. In addition, the COVID-19 pandemic has exacerbated the effects of this disparity. In this regard, digital inclusion, through ICTs, becomes a strategy to close not only technical but also social gaps, thereby bringing well-being to vulnerable groups and favouring compliance with the Sustainable Development Goals (SDGs). Given the importance and topicality of this matter, we conducted a bibliometric analysis, which aims to answer what are the main trends in digital inclusion and digital divide studies and what are the challenges facing digital inclusion initiatives in the social context? For this purpose, we applied a search equation in Scopus and used VOSviewer. With this analysis, we were able to identify the evolution of publications over time and the main authors, countries and topics in the field, and the trends and challenges in digital inclusion initiatives. Finally, we conclude that this study can be used to address other research topics, such as the role of ICTs in the promotion of the SDGs through digital inclusion initiatives, the psychosocial aspects of technology adoption and the need for public policies that serve as a platform for digital and social inclusion.

Despite figures suggesting that Australia is a high consumer of information and communication technologies (ICT), it is well documented that the pattern of this consumption is not spread evenly across the population; a 'digital divide' exists. In general, research suggests that people from higher socioeconomic backgrounds have greater access to ICT compared to those from lower socioeconomic backgrounds. A less well-researched area is the factors that may influence ICT access and usage within certain demographic and socioeconomic groups. This paper presents new data on the access and usage of ICT (computers and the Internet) by 3,404 households and 6,874 children from financially disadvantaged backgrounds. Fifty-nine per cent of the sample had a home computer and just under one-third had the Internet connected at home. The most common location for accessing the Internet was at school. A striking finding was the strong association between the level of parental education and ICT access and use. Schools are important in closing or levelling the access gap, as most students use computers and the Internet at school. However, considering the importance of having home Internet access for children's educational performance, the fact that almost three-quarters of students in this study did not use the Internet at home is of concern, particularly given that almost half of a comparable Australian population have home Internet access. Finding ways to increase the home access of low-income families to the Internet should therefore remain a policy priority for all sectors aiming to bridge the digital divide. Policies aimed at bridging the digital divide should also ensure that programs provide appropriate parenting support and emphasise the educational importance of having home access to computers and the Internet.

Cloud computing has different meaning to different people, the privacy and security issues also differ between a consumer using a public cloud application, a medium-sized Company using a customized Design of business on a cloud platform, and Some Companies are using Platform on Public level which are Public to Public Network The security requirements in cloud computing environment is to find the Security threats in the Structure of clouds To find the security solutions, and finding basis so that Pre Security Step Should be taken in concerned with security future model. In this paper is to build a trusted computing environment for cloud computing system by Combining the trusted computing platform into cloud computing system Which is free from attacks and threats and system is designed with a model system in which cloud computing system is combined with trusted computing platform and trusted platform models.

Cloud computing offers cost effective services on-demand which encourage critical infrastructure providers to consider migrating to the cloud. Critical infrastructures are considered as a backbone of modern societies such as power plants and water. Information in cloud computing is likely to be shared among different entities, which could have various degrees of sensitivity. This requires robust isolation and access control mechanisms. Although various access control models and policies have been developed, they cannot fulfil requirements for a cloud based access control system. The reason is that cloud computing has a diverse sets of security requirements and unique security challenges such as multi-tenant and heterogeneity of security policies, rules and domains. This thesis provides a detailed study of cloud computing security challenges and threats, which were used to identify security requirements for various critical infrastructure providers. We found that an access control system is a crucial security requirement for the surveyed critical infrastructure providers. Furthermore, the requirement analysis was used to propose a new criteria to evaluate access control systems for cloud computing. Moreover, this work presents a new cloud based access control model to meet the identified cloud access control requirements. The model does not only ensure the secure sharing of resources among potential untrusted tenants, but also has the capacity to support different access permissions for the same cloud user. Our focused in the proposed model is the lack of data isolation in lower levels (CPU caches), which could lead to bypass access control models to gain some sensitive information by using cache side-channel attacks. Therefore, the thesis investigates various real attack scenarios and the gaps in existing mitigation approaches. It presents a new Prime and Probe cache side-channel attack, which can give detailed information about addresses accessed by a virtual machine with no need for any information about cache sets accessed by the virtual machine. The design, implementation and evaluation of a proposed solution preventing cache side-channel attacks are also presented in the thesis. It is a new lightweight solution, which introduces very low overhead (less than 15,000 CPU cycles). It can be applied in any operating system and prevents cache side-channel attacks in cloud computing. The thesis also presents a new detecting cache side-channel attacks solution. It focuses on the infrastructure used to host cloud computing tenants by counting cache misses caused by a virtual machine. The detection solutions has 0% false negative and 15% false positive.

In the study of cloud computing and its applications, security has been regarded as one of the greatest problems in the development of cloud computing. Therefore, the study and prevention of computer virus in cloud computing infrastructure becomes practically significant for cloud security. Based on the characteristics of the rapid spread of computer viruses, when a community which is composed by cloud nodes has a higher influence in the cloud-based network, it has a greater potential hazard if there are some viruses lurking in the community. Therefore, it's necessary to find the influential community for virus prevention in cloud infrastructure. To evaluate cross-community influence, this paper proposes a novel method that consists of two components: (1) the Mutual Evaluation Learning (MEL) model for evaluating the pairwise influence between two nodes (clients, servers) and (2) a cross-community influence ranking algorithm (CCIR) designed to quantify the influential strength of each cross-community based on MEL and PageRank. Empirical studies on numerous real networks demonstrate that the proposed method can adapt to different networking scenarios and can reasonably and effectively reflect the distribution of community influence.

Digital divide appears when China coordinates the development of traditional industry and informatization. The main reason is the asymmetric information caused by regional informatization difference. The study uses Keith Griffin's model that is about the generation and diffusion of agricultural green technology revolution, and uses the ideas of information economics to draw an Information and Communications Technology (ICT) diffusion model containing an isoquant. The ICT model can analyze user's different choices in communication technologies in different stages of informatization, and we can identify an ICT gap by crossing the isoquant of different stages and the ratio between different user's capital and laboring. The ICT gap can describe the size of the digital divide. A demonstration analysis is made on the informatization level of Liaoning province by informatization index measuring. The results show that ICT is an efficient way to narrow digital divide and also give suggestions in how to further develop ICT and narrow digital divide.

As a new medium for questionnaire delivery, the internet has the potential to revolutionise the survey process. Online (web-based) questionnaires provide several advantages over traditional survey methods in terms of cost, speed, appearance, flexibility, functionality, and usability [1, 2]. For instance, delivery is faster, responses are received more quickly, and data collection can be automated or accelerated [1- 3]. Online-questionnaires can also provide many capabilities not found in traditional paper-based questionnaires: they can include pop-up instructions and error messages; they can incorporate links; and it is possible to encode difficult skip patterns making such patterns virtually invisible to respondents. Like many new technologies, however, online-questionnaires face criticism despite their advantages. Typically, such criticisms focus on the vulnerability of online-questionnaires to the four standard survey error types: namely, coverage, non-response, sampling, and measurement errors. Although, like all survey errors, coverage error (“the result of not allowing all members of the survey population to have an equal or nonzero chance of being sampled for participation in a survey” [2, pg. 9]) also affects traditional survey methods, it is currently exacerbated in online-questionnaires as a result of the digital divide. That said, many developed countries have reported substantial increases in computer and internet access and/or are targeting this as part of their immediate infrastructural development [4, 5]. Indicating that familiarity with information technologies is increasing, these trends suggest that coverage error will rapidly diminish to an acceptable level (for the developed world at least) in the near future, and in so doing, positively reinforce the advantages of online-questionnaire delivery. The second error type – the non-response error – occurs when individuals fail to respond to the invitation to participate in a survey or abandon a questionnaire before it is completed. Given today’s societal trend towards self-administration [2] the former is inevitable, irrespective of delivery mechanism. Conversely, non-response as a consequence of questionnaire abandonment can be relatively easily addressed. Unlike traditional questionnaires, the delivery mechanism for online-questionnaires makes estimation of questionnaire length and time required for completion difficult1, thus increasing the likelihood of abandonment. By incorporating a range of features into the design of an online questionnaire, it is possible to facilitate such estimation – and indeed, to provide respondents with context sensitive assistance during the response process – and thereby reduce abandonment while eliciting feelings of accomplishment [6]. For online-questionnaires, sampling error (“the result of attempting to survey only some, and not all, of the units in the survey population” [2, pg. 9]) can arise when all but a small portion of the anticipated respondent set is alienated (and so fails to respond) as a result of, for example, disregard for varying connection speeds, bandwidth limitations, browser configurations, monitors, hardware, and user requirements during the questionnaire design process. Similarly, measurement errors (“the result of poor question wording or questions being presented in such a way that inaccurate or uninterpretable answers are obtained” [2, pg. 11]) will lead to respondents becoming confused and frustrated. Sampling, measurement, and non-response errors are likely to occur when an online-questionnaire is poorly designed. Individuals will answer questions incorrectly, abandon questionnaires, and may ultimately refuse to participate in future surveys; thus, the benefit of online questionnaire delivery will not be fully realized. To prevent errors of this kind2, and their consequences, it is extremely important that practical, comprehensive guidelines exist for the design of online questionnaires. Many design guidelines exist for paper-based questionnaire design (e.g. [7-14]); the same is not true for the design of online questionnaires [2, 15, 16]. The research presented in this paper is a first attempt to address this discrepancy. Section 2 describes the derivation of a comprehensive set of guidelines for the design of online-questionnaires and briefly (given space restrictions) outlines the essence of the guidelines themselves. Although online-questionnaires reduce traditional delivery costs (e.g. paper, mail out, and data entry), set up costs can be high given the need to either adopt and acquire training in questionnaire development software or secure the services of a web developer. Neither approach, however, guarantees a good questionnaire (often because the person designing the questionnaire lacks relevant knowledge in questionnaire design). Drawing on existing software evaluation techniques [17, 18], we assessed the extent to which current questionnaire development applications support our guidelines; Section 3 describes the framework used for the evaluation, and Section 4 discusses our findings. Finally, Section 5 concludes with a discussion of further work.

The Digital Divide has been a topic under investigation since the mid-1990s both within and outside the USA. The Digital Divide historically has referred to a social inequity between those individuals who have access to information and communication technology (ICT) and those that do not. In recent years, the notion of the Digital Divide has expanded to include other dimensions beyond access, such as use, knowledge, skills, and dispositions of ICT resources. The Digital Divide manifests itself on a number of dividing factors, such as socioeconomic status, gender, age, culture, geographic location, and more. As formal educational programs are often perceived to be the instrument to correct this social inequity, studying the structure of the Digital Divide in the context of formal educational settings is important to ensure programs are narrowing as opposed to widening the ICT gaps. This chapter presents the Levels of the Digital Divide in Schools presented by Hohlfeld, Ritzhaupt, Barron, and Kemker (2008) as a conceptual framework to characterize the evolving phenomenon. The conceptual framework organizes the Digital Divide into three layers in school settings: (1) access to ICT resources, (2) use of technology by teachers and students, and (3) creation of ICT artifacts to empower students. Recent research literature is thoroughly examined in light of this conceptual framework, and viable solutions are presented using formal educational programs at each level of the model.

In this age the emergence of information and communication technologies (ICTs) has been identified as a major step toward solve the problems challenged the nation development. Problems such as corruption, delays in service delivery, lack of public sector accountability can be overcome with ICT. Furthermore, ICT are the key factors in improving government business and human sustainable development in all life aspects. Whilst the ICT considered the key to these problems but owning these technologies was facing many obstacles staring from bought them to continuous use, and create a gap between countries and within a country from the perspective of who does have computer and networks communication and who doesn't, and this refers to the digital divide. Some aspects of the digital divide exist everywhere and not only related to developing countries but also the size of the gap, which is different in countries and within a single community. This study focuses on the digital divide problem by exploring the current state of the access digital divide in Kingdom of Saudi Arabia (KSA) based on three main research questions. And to achieve that, Data collected from International Telecommunication Union (ITU), Communications and Information Technology Commission (CITC), and World Bank were used. The study found that Saudi Arabia is suffering from the access digital divide, and there is a strong link between household income and the access digital divide resulting from unaffordable prices in both ICT and broadband services and this gap tends to be larger in the regions where the inhabitants have the lowest income level. The study recommends that the government should give improving household income the highest priorities and at the same time offering affordable prices for broadband services. Also, the study finds that mobile penetration represents a valuable resource for the Saudi Arabia government to be investing in delivering government services through mobile platforms. Finally, the study recommends that public-private partnerships with promoting and encouraging the private sectors to invest in ICT is one of the most important measurements in bridging the access digital divide.

BackgroundThe widespread adoption of information and communication technologies (ICTs) further deepens disparities in resource access, particularly among the aging population. However, the relationship between these factors and their resulting impact on cognitive abilities remains uncertain.ObjectiveThis study aims to investigate the potential impact of the digital divide on individuals’ cognitive function and its association with the development and reversion of mild cognitive impairment (MCI).MethodsThis cohort study used data from Beijing Aging Brain Rejuvenation (BABRI) study applying a multistage cluster sampling design between 2008 and 2020. The digital divide was quantified by the frequency of using ICTs. Analysis of covariance (ANCOVA), mixed linear models, and Cox proportional hazards models were used to model the association of digital divide and multidomain cognition.ResultsAmong the 10098 participants, nearly half (n=4941, 48.9%) faced the digital divide, which was associated with a worse performance in processing speed (F10096=10.67; P<.001; effect size r=0.42), rather than memory, executive function, and language. The model indicated that individuals’ physical and mental health, combined with their educational and occupational prestige, influenced the resources they attained, which ultimately caused the digital divide. Moreover, longitudinal data revealed that older adults who successfully crossed the digital divide during the tracking process and those who had already done so prior to tracking showed significantly slower rates of decline in processing speed (B=–1.98, P<.05; B=–2.62, P<.01) and general cognitive function (B=3.50, P<.001; B=3.13, P<.01). Additionally, overcoming the digital divide was also associated with a lower risk of developing MCI (hazard ratio [HR] 0.5, 95% CI 0.34-0.74; HR 0.43, 95% CI 0.29-0.62) and a greater probability of reversion from MCI to normal cognition (HR 6, 95% CI 3.77-9.56; HR 9.22, 95% CI 5.63-15.11).ConclusionsOvercoming the digital divide was significantly associated with improved cognitive function, a slower aging rate in cognitive performance, a reduced risk of developing MCI, and a higher likelihood of reverting from MCI to normal cognition.

Undoubtedly, digital technology (DT) has revolutionalised information and communications technology (ICT) base of the global economy, which has impacted tremendously the socio-economic, political, cultural and scientific development in the majority of the world’s economies. The chapter examines “digital divide” in a broader perspective of information and communications technologies (ICTs) that encompass not only computers, but also telephone (line and cellular), television (TV), radio etc. It is an open secret that ICTs have played and will continue to play a pivotal role in sustaining economic development in the developed countries. Through ICTs, creating, storing and sharing enormous volume of information with relative ease in almost all the spheres of human endeavour have been made possible. The power inherent in ICT that can break up barriers and boundaries holding countries, continents and businesses miles apart can never be over-emphasized. Despite the attendant benefits of ICTs, there are still deep-seated ICT inequalities both within and among the Organization of the Islamic Conference (OIC) member countries. This chapter investigates the depth of the existing digital divide among the OIC member countries and to unearth the possible obstacles. Finally, some policy recommendations have been offered towards the end of the chapter.

Cloud computing is a distributed architecture that has shared resources, software, and information is provided to computers and other devices on a scalable platform and demand. Availability of the cloud services is one of the key security issues in it. Distributed Denial of Service (DDoS) is an attack that threats the availability of the cloud services. In this paper, effect of the DDoS attack on the cloud is investigated. Therefore, a model for attack based on the DDoS is designed, and then we simulate a cloud system on the experimental environment. Experiments show that the cloud system is vulnerable to this attack. In order to confronting this attack, several solutions are proposed in this paper. We suggest load balancing and honeypots beside the intrusion detection systems (IDS) is used to defend from the attack.
