Liu, Liping, Piao, Chunhui, Jiang, Xuehong, Zheng, Lijuan.  2018.  Research on Governmental Data Sharing Based on Local Differential Privacy Approach. 2018 IEEE 15th International Conference on e-Business Engineering (ICEBE). :39—45.

With the construction and implementation of the government information resources sharing mechanism, the protection of citizens' privacy has become a vital issue for government departments and the public. This paper discusses the risk of citizens' privacy disclosure related to data sharing among government departments, and analyzes the current major privacy protection models for data sharing. Aiming at the issues of low efficiency and low reliability in existing e-government applications, a statistical data sharing framework among governmental departments based on local differential privacy and blockchain is established, and its applicability and advantages are illustrated through example analysis. The characteristics of the private blockchain enhance the security, credibility and responsiveness of information sharing between departments. Local differential privacy provides better usability and security for sharing statistics. It not only keeps statistics available, but also protects the privacy of citizens.

Babenko, Liudmila, Pisarev, Ilya.  2018.  Security Analysis of the Electronic Voting Protocol Based on Blind Intermediaries Using the SPIN Verifier. 2018 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery (CyberC). :43—435.

Cryptographic protocols are the basis for the security of any protected system, including the electronic voting system. One of the most effective ways to analyze protocol security is to use verifiers. In this paper, the formal verifier SPIN was used to analyze the security of the cryptographic protocol for e-voting, which is based on model checking using linear temporal logic (LTL). The cryptographic protocol of electronic voting is described. The main structural units of the Promela language used for simulation in the SPIN verifier are described. The model of the electronic voting protocol in the language Promela is given. The interacting parties, transferred data, the order of the messages transmitted between the parties are described. Security of the cryptographic protocol using the SPIN tool is verified. The simulation of the protocol with active intruder using the man in the middle attack (MITM) to substitute data is made. In the simulation results it is established that the protocol correctly handles the case of an active attack on the parties' authentication.

Kő, Andrea, Molnár, Tamás, Mátyus, Bálint.  2018.  A User-centred Design Approach for Mobile- Government Systems for the Elderly. 2018 12th International Conference on Software, Knowledge, Information Management Applications (SKIMA). :1—7.

This paper aims to discover the characteristics of acceptance of mobile government systems by elderly. Several initiatives and projects offer various governmental services for them, like information sharing, alerting and mHealth services. All of them carry important benefits for this user group, but these can only be utilized if the user acceptance is at a certain level. This is a requirement in order for the users to perceive the services as a benefit and not as hindrance. The key aspects for high acceptance are usability and user-friendliness, which will lead to successful-government systems designed for the target group. We have applied a combination of qualitative and quantitative research methods including an m-Government prototype to explore the key acceptance factors. Research approach utilizes the IGUAN framework, which is a user-driven method. We collected and analysed data guided by IGUAN framework about the acceptance of e-government services by elderly. The target group was recruited from Germany and Hungary. Our findings draw the attention to perceived security and perceived usability of an application; these are decisive factors for this target group.

Pandes, Tiffany Lyn O., Omorog, Challiz D., Medrano, Regino B..  2018.  LeMTrac: Legislative Management and Tracking System. :1—6.

{Information and Communications Technology (ICT) have rationalized government services into a more efficient and transparent government. However, a large part of the government services remained constant in the manual process due to the high cost of ICT. The purpose of this paper is to explore the role of e-governance and ICT in the legislative management of municipalities in the Philippines. This study adopted the phases of Princeton Project Management Methodology (PPMM) as the approach in the development of LeMTrac. This paper utilized the developmental- quantitative research design involving two (2) sets of respondents, which are the end-users and IT experts. Majority of the respondents perceived that the system as "highly acceptable" with an average Likert score of 4.72 for the ISO 9126 Software quality metric Usability. The findings also reveal that the integration of LeMTrac within the Sangguniang Bayan (SB) Office in the Municipal Local Government Units (LGU) of Nabua and Bula, Camarines Sur provided better accessibility, security, and management of documents.

Tungela, Nomawethu, Mutudi, Maria, Iyamu, Tiko.  2018.  The Roles of E-Government in Healthcare from the Perspective of Structuration Theory. 2018 Open Innovations Conference (OI). :332—338.

The e-government concept and healthcare have usually been studied separately. Even when and where both e-government and healthcare systems were combined in a study, the roles of e-government in healthcare have not been examined. As a result., the complementarity of the systems poses potential challenges. The interpretive approach was applied in this study. Existing materials in the areas of healthcare and e-government were used as data from a qualitative method viewpoint. Dimension of change from the perspective of the structuration theory was employed to guide the data analysis. From the analysis., six factors were found to be the main roles of e-government in the implementation and application of e-health in the delivering of healthcare services. An understanding of the roles of e-government promotes complementarity., which enhances the healthcare service delivery to the community.

Sayed Javed, Ahmad.  2018.  Total e-Governance: Pros Cons. 2018 International Conference on Computational Science and Computational Intelligence (CSCI). :245—249.

"Good Governance" - may it be corporate or governmental, is a badly needed focus area in the world today where the companies and governments are struggling to survive the political and economical turmoil around the globe. All governments around the world have a tendency of expanding the size of their government, but eventually they would be forced to think reducing the size by incorporating information technology as a way to provide services to the citizens effectively and efficiently. Hence our attempt is to offer a complete solution from birth of a citizen till death encompassing all the necessary services related to the well being of a person living in a society. Our research and analysis would explore the pros and cons of using IT as a solution to our problems and ways to implement them for a best outcome in e-Governance occasionally comparing with the present scenario when relevant.

Ingale, Alpana A., Moon, Sunil K..  2018.  E-Government Documents Authentication and Security by Utilizing Video Crypto-Steganography. 2018 IEEE Global Conference on Wireless Computing and Networking (GCWCN). :141—145.

In our daily lives, the advances of new technology can be used to sustain the development of people across the globe. Particularly, e-government can be the dynamo of the development for the people. The development of technology and the rapid growth in the use of internet creates a big challenge in the administration in both the public and the private sector. E-government is a vital accomplishment, whereas the security is the main downside which occurs in each e-government process. E-government has to be secure as technology grows and the users have to follow the procedures to make their own transactions safe. This paper tackles the challenges and obstacles to enhance the security of information in e-government. Hence to achieve security data hiding techniques are found to be trustworthy. Reversible data hiding (RDH) is an emerging technique which helps in retaining the quality of the cover image. Hence it is preferred over the traditional data hiding techniques. Modification in the existing algorithm is performed for image encryption scheme and data hiding scheme in order to improve the results. To achieve this secret data is split into 20 parts and data concealing is performed on each part. The data hiding procedure includes embedding of data into least significant nibble of the cover image. The bits are further equally distributed in the cover image to obtain the key security parameters. Hence the obtained results validate that the proposed scheme is better than the existing schemes.

Al-Nemrat, Ameer.  2018.  Identity theft on e-government/e-governance digital forensics. 2018 International Symposium on Programming and Systems (ISPS). :1—1.

In the context of the rapid technological progress, the cyber-threats become a serious challenge that requires immediate and continuous action. As cybercrime poses a permanent and increasing threat, governments, corporate and individual users of the cyber-space are constantly struggling to ensure an acceptable level of security over their assets. Maliciousness on the cyber-space spans identity theft, fraud, and system intrusions. This is due to the benefits of cyberspace-low entry barriers, user anonymity, and spatial and temporal separation between users, make it a fertile field for deception and fraud. Numerous, supervised and unsupervised, techniques have been proposed and used to identify fraudulent transactions and activities that deviate from regular patterns of behaviour. For instance, neural networks and genetic algorithms were used to detect credit card fraud in a dataset covering 13 months and 50 million credit card transactions. Unsupervised methods, such as clustering analysis, have been used to identify financial fraud or to filter fake online product reviews and ratings on e-commerce websites. Blockchain technology has demonstrated its feasibility and relevance in e-commerce. Its use is now being extended to new areas, related to electronic government. The technology appears to be the most appropriate in areas that require storage and processing of large amounts of protected data. The question is what can blockchain technology do and not do to fight malicious online activity?

Nowadays citizens live in a world where communication technologies offer opportunities for new interactions between people and society. Clearly, e-government is changing the way citizens relate to their government, moving the interaction of physical environment and management towards digital participation. Therefore, it is necessary for e-government to have procedures in place to prevent and lessen the negative impact of an attack or intrusion by third parties. In this research work, he focuses on the implementation of anonymous communication in a proof of concept application called “Delta”, whose function is to allow auctions and offers of products, thus marking the basis for future implementations in e-government services.

The low attention to security and privacy causes some problems on data and information that can lead to a lack of public trust in e-Gov service. Security threats are not only included in technical issues but also non-technical issues and therefore, it needs the implementation of inclusive security. The application of inclusive security to e-Gov needs to develop a model involving security and privacy requirements as a trusted security solution. The method used is the elicitation of security and privacy requirements in a security perspective. Identification is carried out on security and privacy properties, then security and privacy relationships are determined. The next step is developing the design of an inclusive security model on e-Gov. The last step is doing an analysis of e-Gov service activities and the role of inclusive security. The results of this study identified security and privacy requirements for building inclusive security. Identification of security requirements involves properties such as confidentiality (C), integrity (I), availability (A). Meanwhile, privacy requirement involves authentication (Au), authorization (Az), and Non-repudiation (Nr) properties. Furthermore, an inclusive security design model on e-Gov requires trust of internet (ToI) and trust of government (ToG) as an e-Gov service provider. Access control is needed to provide solutions to e-Gov service activities.

Wang, Xiaozhen.  2019.  Study on E-government Information Security in the Era of Big Data. 2019 IEEE 4th Advanced Information Technology, Electronic and Automation Control Conference (IAEAC). 1:2492—2496.

The government in the era of big data requires safer infrastructure, information storage and data application. As a result, security threats will be the bottleneck for e-government development. Based on the e-government hierarchy model, this thesis focuses on such information security threats as human effects, network technology defects and management deficiency facing the e-government system in the era of big data. On this basis, three solutions are put forward to improve e-government information security system. Firstly, enhance information security awareness and improve network technology of information management departments in the government; secondly, conduct proper information encryption by ensuring information confidentiality and identity authentication; thirdly, implement strict information management through isolation between intranet and extranet and united planning of e-government information management.

Security is one of the main and continual challenges that restrict government stakeholders (e.g. citizens) engagement with the cloud services. This paper has as its objective the discovery of the security perceptions of cloud-based e-government services from the citizens' and IT-staff perspectives. It investigates the factors that influence the citizen's perception of security. Little efforts have been done by previous literature to investigate and analyze the integration between citizens' concerns regarding the perceived security and those of IT -staff, the current study highlights this issue. This work provides an empirical study to understand citizens' priorities, needs and expectations regarding the perceived security of cloud-based e-government services which are a novel e-government initiative in Jordan, also enriches the existing security perceptions literature by introducing new insights. An interpretive-qualitative approach was adopted, as it helps to understand the participants' perceptions in the research natural setting.

Bayaga, Anass, Ophoff, Jacques.  2019.  Determinants of E-Government Use in Developing Countries: The Influence of Privacy and Security Concerns. 2019 Conference on Next Generation Computing Applications (NextComp). :1—7.

There has been growing concern about privacy and security risks towards electronic-government (e-government) services adoption. Though there are positive results of e- government, there are still other contestable challenges that hamper success of e-government services. While many of the challenges have received considerable attention, there is still little to no firm research on others such as privacy and security risks, effects of infrastructure both in urban and rural settings. Other concerns that have received little consideration are how for instance; e-government serves as a function of perceived usefulness, ease of use, perceived benefit, as well as cultural dimensions and demographic constructs in South Africa. Guided by technology acceptance model, privacy calculus, Hofstede cultural theory and institutional logic theory, the current research sought to examine determinants of e- government use in developing countries. Anchored upon the aforementioned theories and background, the current study proposed three recommendations as potential value chain, derived from e-government service in response to citizens (end- user) support, government and community of stakeholders.

Results and Conclusion: The government information sharing model based on the blockchain solution and the transparency of government information can be used as a research framework for information interaction analysis between the government and users. It can also promote the construction and development of information sharing for Chinese government, as well as providing unified information sharing solution at the departmental and regional levels for e-government.

Shayganmehr, Masoud, Montazer, Gholam Ali.  2019.  Identifying Indexes Affecting the Quality of E-Government Websites. 2019 5th International Conference on Web Research (ICWR). :167—171.

With the development of new technologies in the world, governments have tendency to make a communications with people and business with the help of such technologies. Electronic government (e-government) is defined as utilizing information technologies such as electronic networks, Internet and mobile phones by organizations and state institutions in order to making wide communication between citizens, business and different state institutions. Development of e-government starts with making website in order to share information with users and is considered as the main infrastructure for further development. Website assessment is considered as a way for improving service quality. Different international researches have introduced various indexes for website assessment, they only see some dimensions of website in their research. In this paper, the most important indexes for website quality assessment based on accurate review of previous studies are "Web design", "navigation", services", "maintenance and Support", "Citizens Participation", "Information Quality", "Privacy and Security", "Responsiveness", "Usability". Considering mentioned indexes in designing the website facilitates user interaction with the e-government websites.

In this study, we conducted a survey of those who have used E-Government Services (civil servants, employees of public institutions, and the public) to empirically identify the factors affecting the continuous use intention E-Government Services, and conducted an empirical analysis using SPSS and Smart PLS with 284 valid samples except for dual, error and poor answers. Based on the success model of the information system (IS access model), we set independent variables which were divided into quality factors (service quality, system quality, information quality) and risk factors (personal information and security), and perceived ease of use and reliability, which are the main variables based on the technology acceptance model (TAM) that best describes the parameter group, were established as useful parameters. In addition, we design the research model by setting user satisfaction and the continuous use intention as dependent variables, conducted the study about how affecting factors influence to the acceptance factors through 14 hypotheses.The study found that 12 from 14 hypotheses were adopted and 2 were rejected. Looking at the results derived, it was analyzed that, firstly, 3 quality factors all affect perceived ease of use in relation to the quality of service, system quality, information quality which are perceived ease of use of E-Government Services. Second, in relation to the quality of service quality, system quality, information quality and perceived usefulness which are the quality factors of E-Government Services, the quality of service and information quality affect perceived usefulness, but system quality does not affect perceived usefulness. Third, it was analyzed that both factors influence reliability in the relationship between Privacy and security and trust which are risk factors. Fourth, the relationship between perceived ease of use and perceived usefulness has shown that perceived ease of use does not affect perceived usefulness. Finally, the relationship between user value factors (perceptual usability, perceived usefulness and trust) and user satisfaction and the continuous use intention was analyzed that user value factors affect user satisfaction while user satisfaction affects the continuous use intention. This study can be meaningful in that it theoretically presented the factors influencing the continued acceptance of e-government services through precedent research, presented the variables and measurement items verified through the empirical analysis process, and verified the causal relationship between the variables. The e-government service can contribute to the implementation of e-government in line with the era of the 4th Industrial Revolution by using it as a reference to the establishment of policies to improve the quality of people's lives and provide convenient services to the people.

Al-Haj, Ali, Farfoura, Mahmoud.  2019.  Providing Security for E-Government Document Images Using Digital Watermarking in the Frequency Domain. 2019 5th International Conference on Information Management (ICIM). :77—81.

Many countries around the world have realized the benefits of the e-government platform in peoples' daily life, and accordingly have already made partial implementations of the key e-government processes. However, before full implementation of all potential services can be made, governments demand the deployment of effective information security measures to ensure secrecy and privacy of their citizens. In this paper, a robust watermarking algorithm is proposed to provide copyright protection for e-government document images. The proposed algorithm utilizes two transforms: the Discrete Wavelet Transformation (DWT) and the Singular Value Decomposition (SVD). Experimental results demonstrate that the proposed e-government document images watermarking algorithm performs considerably well compared to existing relevant algorithms.

e-Government is needed to actualize clean, effective, transparent and accountable governance as well as quality and reliable public services. The implementation of e-Government is currently constrained because there is no derivative regulation, one of which is the regulation for e-Government Security. To answer this need, this study aims to provide input on performance management and governance systems for e-Government Security with the hope that the control design for e-Government Security can be met. The results of this study are the e-Government Security Governance System taken from 28 core models of COBIT 2019. The 28 core models were taken using CSF and risk. Furthermore, performance management for this governance system consists of capability and maturity levels which is an extension of the evaluation process in the e-Government Evaluation Guidelines issued by the Ministry of PAN & RB. The evaluation of the design carried out by determining the current condition of capability and maturity level in Badan XYZ. The result of the evaluation shows that the design possible to be implemented and needed.

Chen, Yuxiang, Dong, Guishan, Bai, Jian, Hao, Yao, Li, Feng, Peng, Haiyang.  2019.  Trust Enhancement Scheme for Cross Domain Authentication of PKI System. 2019 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery (CyberC). :103–110.
Public Key Infrastructure (PKI) has been popularized in many scenarios such as e-government applications, enterprises, etc. Due to the construction of PKI system of various regions and departments, there formed a lot of isolated PKI management domains, cross-domain authentication has become a problem that cannot ignored, which also has some traditional solutions such as cross-authentication, trust list, etc. However, some issues still exist, which hinder the popularity of unified trust services. For example, lack of unified cross domain standard, the update period of Certificate Revocation List (CRL) is too long, which affects the security of cross-domain authentication. In this paper, we proposed a trust transferring model by using blockchain consensus instead of traditional trusted third party for e-government applications. We exploit how to solve the unified trust service problem of PKI at the national level through consensus and transfer some CA management functions to the blockchain. And we prove the scheme's feasibility from engineering perspective. Besides, the scheme has enough scalability to satisfy trust transfer requirements of multiple PKI systems. Meanwhile, the security and efficiency are also guaranteed compared with traditional solutions.
Ali, Abdullah Ahmed, Zamri Murah, Mohd.  2018.  Security Assessment of Libyan Government Websites. 2018 Cyber Resilience Conference (CRC). :1-4.

Many governments organizations in Libya have started transferring traditional government services to e-government. These e-services will benefit a wide range of public. However, deployment of e-government bring many new security issues. Attackers would take advantages of vulnerabilities in these e-services and would conduct cyber attacks that would result in data loss, services interruptions, privacy loss, financial loss, and other significant loss. The number of vulnerabilities in e-services have increase due to the complexity of the e-services system, a lack of secure programming practices, miss-configuration of systems and web applications vulnerabilities, or not staying up-to-date with security patches. Unfortunately, there is a lack of study being done to assess the current security level of Libyan government websites. Therefore, this study aims to assess the current security of 16 Libyan government websites using penetration testing framework. In this assessment, no exploits were committed or tried on the websites. In penetration testing framework (pen test), there are four main phases: Reconnaissance, Scanning, Enumeration, Vulnerability Assessment and, SSL encryption evaluation. The aim of a security assessment is to discover vulnerabilities that could be exploited by attackers. We also conducted a Content Analysis phase for all websites. In this phase, we searched for security and privacy policies implementation information on the government websites. The aim is to determine whether the websites are aware of current accepted standard for security and privacy. From our security assessment results of 16 Libyan government websites, we compared the websites based on the number of vulnerabilities found and the level of security policies. We only found 9 websites with high and medium vulnerabilities. Many of these vulnerabilities are due to outdated software and systems, miss-configuration of systems and not applying the latest security patches. These vulnerabilities could be used by cyber hackers to attack the systems and caused damages to the systems. Also, we found 5 websites didn't implement any SSL encryption for data transactions. Lastly, only 2 websites have published security and privacy policies on their websites. This seems to indicate that these websites were not concerned with current standard in security and privacy. Finally, we classify the 16 websites into 4 safety categories: highly unsafe, unsafe, somewhat unsafe and safe. We found only 1 website with a highly unsafe ranking. Based on our finding, we concluded that the security level of the Libyan government websites are adequate, but can be further improved. However, immediate actions need to be taken to mitigate possible cyber attacks by fixing the vulnerabilities and implementing SSL encryption. Also, the websites need to publish their security and privacy policy so the users could trust their websites.

Han, Meng, Li, Lei, Peng, Xiaoqing, Hong, Zhen, Li, Mohan.  2017.  Information Privacy of Cyber Transportation System: Opportunities and Challenges. Proceedings of the 6th Annual Conference on Research in Information Technology. :23–28.
The Cyber Transport Systems (CTSs) have made significant advancement along with the development of the information technology and transportation industries worldwide. The rapid proliferation of cyber transportation technology provides rich information and infinite possibilities for our society to understand and use the complex inherent mechanism, which governs the novel intelligence world. In addition, applying information technology to cyber transportation applications open a range of new application scenarios, such as vehicular safety, energy efficiency, reduced pollution, and intelligent maintenance services. However, while enjoying the services and convenience provided by CTS, users, vehicles, even the systems might lose privacy during information transmitting and processing. This paper summarizes the state-of-art research findings on information privacy issues in a broad range. We firstly introduce the typical types of information and the basic mechanisms of information communication in CTS. Secondly, considering the information privacy issues of CTS, we present the literature on information privacy issues and privacy protection approaches in CTS. Thirdly, we discuss the emerging challenges and the opportunities for the information technology community in CTS.
Qayum, Mohammad A., Badawy, Abdel-Hameed A., Cook, Jeanine.  2017.  DyAdHyTM: A Low Overhead Dynamically Adaptive Hybrid Transactional Memory with Application to Large Graphs. Proceedings of the International Symposium on Memory Systems. :327–336.
Big data is a buzzword used to describe massive volumes of data that provides opportunities of exploring new insights through data analytics. However, big data is mostly structured but can be semi-structured or unstructured. It is normally so large that it is not only difficult but also slow to process using traditional computing systems. One of the solutions is to format the data as graph data structures and process them on shared memory architecture to use fast and novel policies such as transactional memory. In most graph applications in big data type problems such as bioinformatics, social networks, and cybersecurity, graphs are sparse in nature. Due to this sparsity, we have the opportunity to use Transactional Memory (TM) as the synchronization policy for critical sections to speedup applications. At low conflict probability TM performs better than most synchronization policies due to its inherent non-blocking characteristics. TM can be implemented in Software, Hardware or a combination of both. However, hardware TM implementations are fast but limited by scarce hardware resources while software implementations have high overheads which can degrade performance. In this paper, we develop a low overhead, yet simple, dynamically adaptive (i.e., at runtime) hybrid (i.e., combines hardware and software) TM (DyAd-HyTM) scheme that combines the best features of both Hardware TM (HTM) and Software TM (STM) while adapting to application's requirements. It performs better than coarse-grain lock by up to 8.12x, a low overhead STM by up to 2.68x, a couple of implementations of HTMs (by up to 2.59x), and other HyTMs (by up to 1.55x) for SSCA-2 graph benchmark running on a multicore machine with a large shared memory.
