Data Deduplication Strategies in Cloud Computing

Cloud computing assumes an essential job in the business stage as figuring assets are conveyed on request to clients over the Internet. Distributed computing gives on-request and pervasive access to a concentrated pool of configurable assets, for example, systems, applications, and administrations This guarantees the vast majority of undertakings and number of clients externalize their information into the cloud worker. As of late, secure deduplication strategies have bid extensive interests in the both scholastic and mechanical associations. The primary preferred position of utilizing distributed storage from the clients' perspective is that they can diminish their consumption in buying and keeping up capacity framework. By the creating data size of appropriated registering, a decline in data volumes could help providers reducing the costs of running gigantic accumulating system and saving power usage. So information deduplication strategies have been proposed to improve capacity effectiveness in cloud stockpiles. Also, thinking about the assurance of delicate documents. Before putting away the records into the cloude stockpile they frequently utilize some encryption calculations to ensure them.In this paper we propose stratagies for secure information deduplication

The Future of Library Services in the Digital Economy

Libraries may be on the verge of a revolutionary phase of integrating technology in all their services in order for them to become effective information providers in the digital economy. In much of the literature on the potential of ICTs in academic libraries, it is argued that advancements in ICTs are changing the way people are accessing and using information. Hence, integration of ICTs in library services is necessary if libraries are to effectively provide information at anytime and anywhere. This chapter seeks to address this issue with a focus on the Copperbelt University library in Kitwe, Zambia. The chapter reviews various similar sources that looked at technology and its impact on library services. Additionally, in the African context, there has been massive adoption of Internet-enabled technologies. For example many people have smart phones such as Blackberries, Samsung, Nokia and Apple iPhones, which enable them access Internet ubiquitously. The emergence of these technologies and their abilities to provide tailor made applications for pervasive access to information resources entails that even library content may now be provided on electronic platforms. Whereas the rest of the world has done a substantial amount towards electronic library systems, not much has been done in Africa. Despite such challenges, libraries are taking steps in modernizing their services in an effort to fully satisfy the ever-changing needs of their information users. Additionally, recommendations on what libraries ought to do in order for them to bridge the widening gap in terms of how people are accessing and using information are given.

mVITAL

Pervasive care and chronic disease management to reduce institutionalization is a priority for most western countries. The realization of next generation ubiquitous and pervasive healthcare systems will be a challenging task, as these systems are likely to involve a complex structure. Such systems will consist of various devices, ranging from resource-constrained sensors and actuators to complex multimedia devices, supporting time critical applications. This is further compounded by cultural and socio-economical factors that must be addressed for next generation healthcare systems to be widely diffused and used. In this study, the requirements for a vital sign monitoring solution are derived and based on these requirements a standards compliant medical device networking solution is presented. mVITAL is an end-to-end solution based on IEEE-11073 framework. IEEE-11073 defines a family of standards and nomenclature for device communication protocol, data format and logical interface between monitoring station and standard compliant medical devices. mVITAL is not only providing medical sensor networking and vital sign monitoring but also closes the loop by signaling alert messages to the caregiver and allowing pervasive access to vital signs of a patient using smartphones over a heterogeneous network. A role based access control mechanism is developed to limit the access to secure data. The end-to-end delay and the variations in delay for both the sensor data collection and the pervasive access are analyzed. mVITAL is developed as a complementary solution augmenting functionality of a hospital information system and can be loosely coupled with the hospital information system using web services.

Valuation of Alternative Business Models in Information, Communication and Media Markets

Information, Communication and Media Markets (ICMM) are in a process of tremendous change. IP-based technologies and services such as broadband and triple/quadruple-play are realities that have the ability to enforce the convergence of so far parallel industries, that is, Telephony, Internet, and Broadcast. In this paper, the authors derive a scenario where a telecom operator aims to design, develop, and validate a global B3G (Beyond 3rd Generation) framework to support secure, personalized, and pervasive telecommunications services built on heterogeneous network and service infrastructures. The authors rethink the telecommunications architecture and business models to enable easy, seamless, and pervasive access to content and services, while supporting user preferences and context. This proposal involves significant changes in current industry business models. A value chain approach allows the identification of different scenarios, where the firm faces several options from which to choose. The authors investigate operators’ decision process and evaluates the project based on its flexibility, using a real option approach.

Content online and the end of public media? The UK, a canary in the coal mine?

Online delivery of content has changed media advertising markets, undermining the business model which has underpinned provision of ‘public media’. Three business models have sustained mass media: direct payment for content, payment for advertising and state subsidy, and the author argues, contrary to others’ claims, that advertising finance has made possible production and provision of high-quality, pluralistic and affordable public media. In consequence, substitution of the internet as an advertising medium has undermined the system of finance which, in the UK and societies like it, sustained public media. Global advertising revenues have both fallen and been redistributed, though to differing degrees in different countries, with particularly deleterious effects on local newspapers. Prices have risen, original content production has fallen and reversion to a direct payment-for-content business model is pervasive. And this despite the growth of new entrant online media and established publicly funded media (notably public service broadcasters) resulting in the likelihood of a continued general worsening of affordable and pervasive access to high-quality and diverse public media.

Medical Data Visualization via a Pervasive Multi-Agent Platform

Pervasive healthcare is the field of application emerging from the combination of healthcare with pervasive computing, which is the computing paradigm that provides users with access to services in a transparent way, wherever they are and whichever their interacting device is. In this paper, a software infrastructure for pervasive healthcare is presented. Such an infrastructure aims at supporting medical practitioners with advanced pervasive access to medical data, which is also context-aware in the sense that the modality to fruit data depends on the device used by the operator and on his or her physical position within the environment. The paper also describes a service for high quality 3D rendering of medical volume data, which takes advantage of the software infrastructure to distribute the computational load upon the devices available in the environment in a completely transparent way to users.
