Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. XML Key Management Specification (XKMS) uses the web services framework to make it easier for developers to secure inter-application communication using public key infrastructure (PKI). XML Key Management Specification is a protocol developed by W3C which describes the distribution and registration of public keys. Services can access an XKMS compliant server in order to receive updated key information for encryption and authentication. The XKISS service specification is concerned with management of the public component of a public key pair. The XKRSS is concerned with management of private keys.
Increase in the use of images in the continuous expansion of multimedia applications has increased the demand for efficient techniques that can store and transmit visual information. This demand has made image compression a vital factor. This work proposes compression techniques for compound images. For this purpose, the primary goal was set as to develop compression schemes that can compress color compound images quickly, which can reduce the compression rate, while maintaining a good level of visual quality in a secure fashion . Here two types of segmentation techniques (i) layer-based segmentation and (ii) block-based segmentation are analyzed and two hybrid models are proposed. The first hybrid model combines histogram-threshold block-based technique with wavelets and the second model combines layer and block-based techniques for efficient compression. Security to image content is provided in three ways, namely, Block Transformation Coding (BTC), XML transformation and conversion for text block and Encryption of image blocks. Experiments are conducted with the traditional compressors which prove that the proposed models give better results.

XML Encryption, also known as XML-Enc, is a specification, governed by a W3C recommendation, that defines how to encrypt the contents of an XML element. Although XML Encryption can be used to encrypt any kind of data, it is nonetheless known as "XML Encryption" because an XML element contains or refers to the cipher text, keying information, and algorithms. Both XML Signature and XML Encryption use the KeyInfo element, which appears as the child of a SignedInfo, EncryptedData, or EncryptedKey element and provides information to a recipient about what keying material to use in validating a signature or decrypting encrypted data. The KeyInfo element is optional: it can be attached in the message, or be delivered through a secure channel.
This book provides and in-depth examination of the core concepts and general principles of web application development, using examples from specific technologies. This conceptual knowledge is critical when designing and debugging complex systems, and makes it easier to learn the new application programming interfaces (APIs) that arise in the rapidly changing Internet environmentSplit into three sections:HTTP protocol as a foundation for web applicationsDiscussion of markup languages such as HTML, XML and CSSSurvey of emerging technologiesIncludes new coverage on technologies including:Rapid application approaches Ruby on RailsApplication PrimersSearch technology, including Search Engine Optimization·Simple Object Access Protocol (SOAP)·XML Path Language (XPath)Platform for Privacy Preferences (P3P)User-generated content technology for community websites and online collaboration applicationsSecurity and encryption It is not enough for Web application developers to be proficient in just one platform. As platforms grow and evolve, and as new ones arise, developers must be able to transfer their proficiency across platforms in order to build complex Web applications effectively. This book helps developers understand the underlying core technologies so that they can learn new APIs and application frameworks more quickly.Web Application Architecture provides an in-depth examination of the basic concepts and general principles associated with Web application development, using examples that illustrate specific technologies. This conceptual knowledge is critical when building and deploying complex systems that are scaleable, extensible, maintainable and reusable. The book explains the underlying protocols and languages that support Web application development, and delineates the best practices associated with building robust applications. It describes mechanisms for providing Web access to heterogeneous data sources including relational databases and multimedia.The new edition includes brand new and fully updated chapters on:Internet protocols - from TCP/IP to HTTP and beyondsoftware components - servers, browsers, proxies and agentsthe dynamic web - how web applications present dynamic datamarkup languages - HTML, XML and CSStools, libraries and frameworks - AJAX, Struts, and Ruby on Railssearch technologies - underlying principles, application design, and SEOfuture directions and emerging technologies - XML Query, RDF, and the Semantic WebIdeally suited for course usage and self-study, this practical, engaging textbook is essential reading for students, programmers and system architects and designers alike. It provides a comprehensive, timely overview of modern web technology.Visit the supplementary website at www.wileyeurope.com/college/shklar
The LNCS journal Transactions on Large-Scale Data- and Knowledge-Centered Systems focuses on data management, knowledge discovery, and knowledge processing, which are core and hot topics in computer science. Since the 1990s, the Internet has become the main driving force behind application development in all domains. An increase in the demand for resource sharing across different sites connected through networks has led to an evolution of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications providing high scalability. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between grids, P2P systems, and agent technologies is the key to data- and knowledge-centered systems in large-scale environments.This, the ninth issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, contains five revised selected regular papers focusing on the following topics: top-k query processing in P2P systems, self-stabilizing consensus average algorithms in distributed sensor networks, recoverable encryption schemes, xml data in a multi-system environment, and pairwise similarity for cluster ensemble problems.
