Proposed cookies based and an inverse cookie based virtual password authentication protocols are very effective to thwart online dictionary attacks because the computation cost of login on to the web server increases exponentially with each login failure for an attacker. We proposed an efficient SSO password based two-server architecture in which the user has to login once to get a valid ticket. Improvements to several static and dynamic identity based authentication protocols have also been suggested. The proposed dynamic identity based authentication protocols aim to provide the privacy to the user`s identity so that users are anonymous in communication channel. Also the concept of two- tier authentication for the client makes it difficult for an attacker to guess out the information pertaining to password and ticket. The work presented in this book is a step toward making e-commerce transactions more reliable and secure. ····· 10361103030

For this purpose, a software system was developed to implement buffer strategy at sender and receiver sides. Four experiments were performed under this system and five scenarios were designed under each experiment. A subjective test of MOS was conducted for all the scenarios to collect people`s perception about three different videos. People from different background and of different age group were invited to take part in all the experiments. MATLAB and MS Excel were used for data collection and plotting graphs. We conclude that people have convergence of opinions when communication break time increases than the size of buffers at both ends. Finally, the MOS ratings of this subjective test prove that by the use of same size buffers at both ends improves the user`s perceived quality of video at acceptable level. Because of empirical study, the main focus was on implementation strategy of buffers at both ends. The implementation strategy was the design of a number of scenarios in which the statistics of the behavior of sender and receiver buffers have been collected. ····· 10361102633

Creating new relationships is often one of the challenges that older adults may encounter. The Internet opens new options for communication and may change the extent to which people are involved in community. Use of the Internet as a new communication technology may lead to changes in older adults` social relationships. Social networks facilitate interaction among people and may influence the production of social capital. Social capital is defined as `features of social organisation such as networks, norms and trust that facilitate coordination and co-operation`. Social capital is a multidimensional approach which includes diverse aspects of social structure. Although it is increasingly obvious that the Internet is changing the way humans live, the details of this change are not yet clear. A major debate in current literature involves the capacity of the Internet to enhance social capital and wellbeing in old age. In this regard, the present study attempts to investigate the relationships between Internet use and seniors` social capital and wellbeing. ····· 10361101676

This study itself discusses the potential for promoting cyber democracy through interactivity, on the Internet. Both interactivity and cyber democracy will lead to a broadening of the Zimbabwean public sphere by including online newspapers in the media circle. It views interactivity, cyber democracy and the public sphere as central to free expression. Zimbabwean online newspapers are not fully exploiting the Internet`s potentials to promote the threefold ideal for public deliberations identified in this study. The content analysis of 22 Zimbabwean online newspapers revealed that many newspapers are providing interactive tools that are of limited relevance to interactive communication. The different models for assessing interactivity, cyber democracy and the public sphere in the online newspapers that were employed in this study point to very low levels of interactivity, hence the rest of the components were affected.

As an essential component of the web based educational systems, the student model enables the system to provide individualised course contents and study guidance, and therefore to help the students with different backgrounds and knowledge levels to achieve their learning goals effectively on the web. A prototype student model was developed in this project for a web based learning system. The architecture of student model is divided in two parts: individual and group student models. The information contained in individual student model includes the student knowledge levels for course contents, study goals, learning styles, preferences, etc. The model is updated dynamically according to student study times and/or assessment results. The group student model is extracted by a cumulative analysis of the individual student models of various students and is used for giving guidance to the students.

However, there are challenges facing interactive e- learning environments Like the available bandwidth and the need for Real-Time communication. According to these and other challenges, the system performance should be analyzed deeply. Interactive e-learning environment, to be most effective, should provide different components and tools that allow different types of interaction between speaker and attendees. Creation and integration between all required components is not trivial as different privileges are granted to different users. To create such rich environment, technologies used should be selected carefully to satisfy real time and learning environment constraints. For instance, a streaming server is a must to stream audio/video and other data to all attendees simultaneously. Client components are preferred to be compatible with the server not to waste resources. With integrated clients and server, we could build an interactive environment providing the required functionality and interactivity. ····· 10361100949

People are capable of using the Web for tasks such as finding places by name, reserving books, tickets, searching for the lowest price to buy, and so on. A computer cannot accomplish the same tasks without human direction because web pages are designed to be read by people and not by machines. The semantic web is a vision of information that is understandable by computers, so that they can perform more of the tedious work involved in finding, sharing, and combining information on the web. It involves languages specifically designed for data and web data management and comprises a set of design principles and a variety of technologies.

The main objective of Information Retrieval (IR) systems is to satisfy searchers needs. We present a more realistic view of searchers needs by considering not only theories from information retrieval and information science, but also from psychology, philosophy, and sociology. We extensively report on the role of emotion in every aspect of human behaviour, both at an individual and social level. This serves not only to modify the current IR views of emotion, but more importantly to uncover social situations where emotion is the primary factor (i.e., source of motivation) in an Information Retrieval and Seeking process. We also show that the emotion aspect of documents plays an important part in satisfying the searcher s need, in particular when emotion is indeed a primary factor. Given the above, we define three concepts, called emotion need, emotion object and emotion relevance, and present a conceptual map that utilises these concepts in IR tasks and scenarios. ····· 1036191810

Intruders and hackers have also learnt, and become more tech savvy. This raises the need to introduce a better and more reliable authentication mechanism which is not dependent on a series of characters, but rather on a technology that is unique and only possessed by the individual. Another problem faced by modern-day Internet users is that they are required to maintain a long list of passwords for their web accounts - maybe 15-20 accounts. In this book, we propose a one-stop solution to eliminate all these problems a new security model based on Fingerprint Recognition for Distributed Systems.

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Lack of sufficient semantic description makes it difficult to find and compose suitable Web services during analysis, search, and matching processes. As Semantic Web Services provide well-defined meaning, composition of new services is possible through logical deductions achieving resolutions automatically. This book develops an Inference-based Semantic Business Process Composition Agent (SCA). Utilizing Revised Armstrong s Axioms (RAAs) in inferring functional dependencies, SCA System composes available OWL-S based atomic processes into required services. RAAs are embedded in the knowledge base ontology of SCA System. In order to find functional dependencies between processes in the candidate set of SWSs, the Semantic Matching Step (SMS) was prepared using a well-organized matchmaking algorithm. The SMS scores the similarity of two focused-on processes based on the assessment of distance among concepts. Experiments show that the SCA System produces process sequences as a composition plan that satisfies user s requirement for a complex task. The SCA System is the first to use RAAs for semantic-based planning and inference. ····· 1036188777
