    Quality of Service (QoS) is a set of non-functional requirements that could enhance the adoption rate of web services. It is essential to consider the QoS requirements for web services in order to guarantee for quality of web services and attract more users. There are many QoS scenarios such as QoS computation, QoS evaluation, QoS specification, QoS prediction and QoS measurement. In this paper, we prepare a systematic review study to provide a broad vision of primary studies to researchers in QoS scenarios to find the gaps and give the overview to perform researches to fill in the gap. The study focuses on these five most usable digital libraries including the IEEE Explorer,Springer link, ISI web of Knowledge, Emerald, and Science Direct between 2001 and 2012. The result shows that there is an urgent need to do research especially in QoS prediction and QoS computation

    A fuzzy-based technique for describing security requirements of intrusion tolerant systems

    Get PDF
    To care for security in early stages of software development has always been a major engineering trend. However, due to the existence of unpreventable and accidental security faults within the system, it is not always possible to entirely identify and mitigate the security threats. This may eventually lead to security failure of the target system. To avoid security failure, it is required to incorporate fault tolerance (i.e. intrusion tolerant) into the security requirements of the system. In this paper, we propose a new technique toward description of security requirements of Intrusion Tolerant Systems (ITS) using fuzzy logic. We care for intrusion tolerance in security requirements of the system through considering partial satisfaction of security goals. This partiality is accepted and formally described through establishment of a Goal-Based Fuzzy Grammar (GFG) and its respective Goal -Based Fuzzy Language (GFL) for describing Security Requirement Model (SRM) of the target ITS

    Since the web services are growing rapidly in cloud, service consumers and providers are looking for a means to find better services that satisfy both parties. From both user’s and developer’s perspectives, discovering functional and non-functional characteristics of a web service is essentially considerable. Due to over-coming the above issues many research have been published to improve the usage of web services to satisfy customers. The paper reviews the literature of web services with respect to quality of service (QoS) or non-functional properties, to acquire better understanding of concepts and issues related to QoS web service selecting and discovering processes

    Facilitate recycle activities via ICT and physical approach

    Recycle, reuse and reduce are commonly heard as the activities to support for green environment. However, without or lack of self awareness and voluntary to contribute to the green it can cause a failure effort and projects from the government and other sectors. Furthermore, the public could not be expected to keep recycling without enough motivation, assistance and facility. Alternatively, we proposed a web application as an e-platform for the community and business entity including shopping mall, green business and other agencies to support and collaborate between each other in supporting for recycle and reuse. We have investigated through survey and interview with those involved including the public and representatives from the selected shopping malls to collect data of the current scenario regarding their awareness and willingness to contribute to green. Our solution called e-Reward for Recyclers purposely to motivate people to recycle their used items from home at one stop recycling centre by collaborating with shopping malls. Lastly, we wanted to connect people from the green business including recycle factory, reused company and welfare organization to the recycle centre for them to collect mass recycled items to be reused for their purposes

    A review of cloud migration techniques and models for legacy applications: key considerations and potential concerns

    Get PDF
    Legacy systems refer to the applications designed for a particular client that have been in use for a long period of time and developed using obsolete technologies. They are often business-critical systems therefore any changes here inevitably will affect the other parts of the system. Although these systems are considered to be outdated, they are too costly and risky for an organization to replace it. Cloud computing provides a new platform for organization that promises flexible scalability, business agility, high availability and reduction in costs. Considering these benefits, migration of legacy systems to cloud is a lucrative option for many organizations. However the architecture of these legacy applications require a tested, fool-proof and risk free approach for migration. Limited migration models or frameworks have been proposed which caters issues of legacy systems migration to cloud platform. Many of these cloud adoption techniques and models emphasize on the generic phases and procedures on migrating the applications and data to cloud. However some of these models are more flexible, and provide better approaches compared to others. This research explores the issues associated with the legacy applications with regards to their migration on cloud and reviews the existing techniques and models that have been proposed in this context

    A generic framework for e-commerce requirements to comply with Sharia in business-to-consumer perspective

    Get PDF
    The serious concern over fulfillment of the essential requirements of Sharia by the conventional e-commerce system constitutes a barrier to e-commerce adoption and use among many Muslims. Therefore, it is important to explore and understand the essential requirements for Sharia compliant e-commerce specifically in Business to Consumer (B2C) setting. Our research has identified the necessary requirements for e-commerce Sharia compliant. The requirements are categorised into two; Islamic law of contract, and Sharia prohibition in e-commerce. The requirements for Islamic law of contract those include compliant with form (offer and acceptance), contracting parties (buyer and seller), and subject matter (object and price). In addition, the requirements for prohibition in e-commerce are referred to the avoidance of fundamentally prohibited elements of riba, gharar, haram and maysir. Furthermore, we have developed a generic framework of requirements for B2C Sharia compliant e-commerce. This framework will serve as a guide to consumers in determining the legitimacy of an e-commerce transaction in the light of Sharia. Besides, e-commerce merchants, web application developers and other stakeholders will gain clear understanding of these requirements to improve the development and diffusion of Sharia compliant e-commerce application. Conclusively, this research postulates that, any e-commerce transaction or platform that complies with the Islamic law of contract and is devoid of any fundamentally prohibited element (riba, gharar, haram and maysir) is deemed Sharia compliant

    Sharia compliance service quality metrics for e-commerce: An exploratory analysis

    Get PDF
    Despite the rising call for Sharia compliance in e-commerce systems, yet there are no established service quality metrics that would ensure Muslim consumer trust, use and users satisfaction. Therefore, we prudently proffered Sharia compliance service quality metrics for e-commerce that would foster e-commerce use, user satisfaction and net benefits for the over 1.8 billion Muslims globally. By deducing extant e-commerce service quality metrics from literature and harnessing the opinion of Sharia compliance scholars/experts, an integrative Sharia compliance service quality metrics for e-commerce are proffered. Fundamentally, Sharia compliance assurance of e-commerce systems is found to be an essential service quality metric that will ensure Muslim consumer trust, use, user satisfaction and net benefits from e-commerce.Whereas, conventional e-commerce service quality best practices that are aimed at enhancing the welfare and devoid of Sharia violations are also deemed important service quality metrics for Sharia compliance. Because, providing pre-sale, during the sale and post-sale support services are vital in ensuring the Sharia obligation of eliminating uncertainties, risk, losses, displeasure and discord emanating from e-commerce

    An integrated approach towards Sharia compliance e-commerce trust

    The Sharia compliance trust concerns over the conventional e-commerce systems among devoted Muslims causes reluctance and abstinence to partake in e-commerce transactions. Although e-commerce trust building mechanisms have been highlighted in the extant literature, there has not been any integrative or exhaustive solution to the Sharia compliance trust concerns of Muslims. Therefore, it became necessary to develop a framework that will provide a guide towards achieving Sharia compliance e-commerce trust (SCE-C). Consequently, relevant literature on e-commerce trust from a conventional perspective and the Sharia perspective were reviewed to gain a background. It provided the basis for proffering a framework for SCE-C trust with a view to enhancing e-commerce adoption and use by Muslims around the world. The framework for SCE-C Trust highlights that e-commerce vendor trustworthiness factors comprising of Sharia compliance, integrity, benevolence, competence, website quality, and third-party assurance if positively moderated by consumer trust propensity and religious commitment will ensure SCE-C trust

    E-commerce quality evaluation metrics: a sharia compliance approach

    Get PDF
    There is a growing concern and need for Sharia compliance e-commerce quality metrics to evaluate policies and practice that will ensure that Sharia principles are adhered and user’s desirable characteristics are provided. Therefore, extant conventional e-commerce quality metrics from the literature are critically reviewed. Furthermore, an exploratory study involving Sharia compliance experts was conducted, revealing adherence to the maqasid Sharia and the principles of Islamic law of contract as the fundamental Sharia compliance requirements for e-commerce systems. Hence, we integrated the relevant conventional e-commerce quality metrics and the Sharia compliance requirements deduced to propose a set of Sharia compliance e-commerce quality metrics based Information, systems and service quality dimensions. The Sharia compliance e-commerce information quality metrics proffered are accuracy, relevance, timeliness, understandability, completeness, and currency. System quality metrics involves being devoid of riba, devoid of gharar, devoid of haram objects, ethical advertisements, usability, reliability, functionality, customization, security, and privacy. While Service quality metrics are Sharia compliance assurance, khiyar policy, responsiveness, empathy, follow-up services, and the effectiveness of online support capabilities. Developing and evaluating Sharia compliance e-commerce quality based on the proposed metrics is envisaged to foster Muslim consumer trust, use and user satisfaction with e-commerce systems
