Mobile data services in combination with profluent web services are seemingly the path breaking domain in current information research. Effectively, these mobile web services will pave the way for exciting performance and security challenges, the core needto-be-addressed issues. On security front, though a lot of standardized security specifications and implementations exist for web services in...

Security is a very important aspect for web service technology. Many people find the idea of creating security metrics to be a daunting task. Secure web service discovery aims at finding the best component services that satisfy the end-to-end security requirements between service consumer and service provider. The term "metrics or criteria" refers to specific objectives that have defined securi...

Web service technology is a new technology for the Internet in recent years, and is extensively taken as the important technology in the next generation dynamic e-commerce. But the dynamic e-commerce’s development speed is affected by itself security, that’s the web service security. In this paper, the backgrounds and concepts of dynamic electronic commerce are introduced, and then its security...

Web Services are regarded as the premier building blocks of Service-Oriented Architectures (SOA). Founding on specifications for basic communication patterns and message syntax, a lot of additional Web Service specifications that address non-functional requirements have been introduced. The most relevant specifications for these non-functional requirements deal with security aspects of Web Serv...

The Service Oriented Architecture (SOA) becomes an essential element of modern Enterprise Application Integration (EAI). Among the available SOA implementations, Web Services are most preferable choice by the enterprises as they operate on simple Internet protocols. In principle, web services use SOAP protocol as a base for transmitting requests and responses in between service requester and se...

Security and trust aspects, perceived as difficult to quantify, have been neglected in various service interactions. However, factors related to security and trust are in fact crucial in the overall value of service quality. A security ontology that enables a quantification of risks related to the usage of Semantic Web services in enterprise information systems was created to meet users’ requir...

The massive and automated access to Web resources through robots has made it essential for Web service providers to make some conclusion about whether the "user" is a human or a robot. A Human Interaction Proof (HIP) like Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) offers a way to make such a distinction. CAPTCHA is a reverse Turing test used by Web serv...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...
