The Application of XML Key Management Specification in e-Business

The technology of PKI can satisfy most of the needs of security in e_Business. But it is restricted to use the PKI technology adequately because applications can not know the PKI System very well without an uniform architecture standard of PKI system. Now, XKMS gives the standard of key management, so applications can use the underlying PKI system transparently by using the standard interfaces. In this paper, we introduce the XKMS Web Services and the client software development kit (brief as CSDK) developed by ourselves. The web services and the CSDK are all in accord with the XKMS specification.. We also have developed an application system about e_Business to see how to call the web services by using the CSDK

Data hiding in multimedia - theory and applications

Multimedia data hiding or steganography is a means of communication using subliminal channels. The resource for the subliminal communication scheme is the distortion of the original content that can be tolerated. This thesis addresses two main issues of steganographic communication schemes: 1. How does one maximize the distortion introduced without affecting fidelity of the content? 2. How does one efficiently utilize the resource (the distortion introduced) for communicating as many bits of information as possible? In other words, what is a good signaling strategy for the subliminal communication scheme? Close to optimal solutions for both issues are analyzed. Many techniques for the issue for maximizing the resource, viz, the distortion introduced imperceptibly in images and video frames, are proposed. Different signaling strategies for steganographic communication are explored, and a novel signaling technique employing a floating signal constellation is proposed. Algorithms for optimal choices of the parameters of the signaling technique are presented. Other application specific issues like the type of robustness needed are taken into consideration along with the established theoretical background to design optimal data hiding schemes. In particular, two very important applications of data hiding are addressed - data hiding for multimedia content delivery, and data hiding for watermarking (for proving ownership). A robust watermarking protocol for unambiguous resolution of ownership is proposed

BUSINESS PERSPECTIVE E-BANKING SYSTEMS IN INDIA

The paper seeks to explore how internet or e-banking has improvised the efficiency and adequacy in the banking sector within a very short span of time, Research Design/Process in Financial Organization, Methods of Data Collection, taking into consideration the trends, challenges of E-banking, the security measures and propound a solution that can root out the fraud in e-banking. I would like to thank my professor Dr. Stephen Onu for all the guidance he is providing me for the completion of the paper. I would also want to thank Professor Prof. John Clark for helping me out with the research with the thesis topic. I would say this paper would never have been possible without them. I shall also thank my friends and family who for being supportive right from the day I have started my research work. And finally, I would like to thank Harrisburg University for providing me with all the resources and guidelines required for the research

Leveraging contextual-cognitive relationships into mobile commerce systems

A thesis submitted to the University of Bedfordshire in partial fulfilment of the requirements for the degree of Doctor of PhilosophyMobile smart devices are becoming increasingly important within the on-line purchasing cycle. Thus the requirement for mobile commerce systems to become truly context-aware remains paramount if they are to be effective within the varied situations that mobile users encounter. Where traditionally a recommender system will focus upon the user – item relationship, i.e. what to recommend, in this thesis it is proposed that due to the complexity of mobile user situational profiles the how and when must also be considered for recommendations to be effective. Though non-trivial, it should be, through the understanding of a user’s ability to complete certain cognitive processes, possible to determine the likelihood of engagement and therefore the success of the recommendation. This research undertakes an investigation into physical and modal contexts and presents findings as to their relationships with cognitive processes. Through the introduction of the novel concept, disruptive contexts, situational contexts, including noise, distractions and user activity, are identified as having significant effects upon the relationship between user affective state and cognitive capability. Experimental results demonstrate that by understanding specific cognitive capabilities, e.g. a user’s perception of advert content and user levels of purchase-decision involvement, a system can determine potential user engagement and therefore improve the effectiveness of recommender systems’ performance. A quantitative approach is followed with a reliance upon statistical measures to inform the development, and subsequent validation, of a contextual-cognitive model that was implemented as part of a context-aware system. The development of SiDISense (Situational Decision Involvement Sensing system) demonstrated, through the use of smart-phone sensors and machine learning, that is was viable to classify subjectively rated contexts to then infer levels of cognitive capability and therefore likelihood of positive user engagement. Through this success in furthering the understanding of contextual-cognitive relationships there are novel and significant advances that are now viable within the area of m-commerce
