Cloud computing is an Internet based development, in concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure that supports them. According to a 2008 IEEE paper, -Cloud Computing is a paradigm in which information is permanently stored in servers on the internet and cached temporarily on clients that include desktops, entertainment centers, table computers and notebooks etc.‖ Some examples of emerging Cloud computing infrastructures are Microsoft Azure, Amazon EC2, Google App Engine, and Aneka. Cloud service providers enable users to access and use the necessary resources via the internet. To provide these resources, providers often fall back upon other providers in the cloud, hence this raises security issues in Cloud Environment as Clouds have no borders and the data can be physically located anywhere in the world. So this phenomenon raises serious issues regarding user authentication and data confidentiality. Hence it is proposed to implement a simple Data Protection framework which performs authentication, verification and encrypted data transfer, thus maintaining data confidentiality. Programming is performed using JAVA platform, Cloud environment is created using wired and wireless LAN networks. And Advanced Encryption Standard security algorithm is implemented for ensuring security framework.
The present educational systems are trying to incorporate the semantic web technologies, so as to provide an adaptable, personalized and an intelligent learning environment. The long term vision of Education is to provide AAAL: Anytime, Anywhere, Anybody Learning. This paper discusses the architecture of semantic web for the purpose education system which satisfies AAAL .It contains an overview of how ontology can represent the knowledge base which forms the backbone of the Semantic Web based Educational system, thus making the system useful to the learners. It also contains methods on how ontology construction can take place for a particular domain.
Abstract-The education system in rural and semi-rural areas of developing and underdeveloped countries are facing many challenges. The limited accessibility and challenges to the education are attributed mainly to political, economic and social issues of these underdeveloped countries. We propose a "Feasible Rural Education System (FRES)" based on Ontology and supported by Cloud to enhance the accessibility to education in rural areas. The system has been proposed incorporating the FOSS approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
