Multimedia content delivery applications are becoming widespread thanks to increasingly cheaper access to high bandwidth networks. Also, the pervasiveness of XML as a data interchange format. has given rise to a number of standard formats for lIlultimedia, such as Sl\HL for multimedia presentations, SVG for vector graphics, VoiceXML for dialog, and MPEG-21 for video. Innovative programming paradigms (such as the one of Web services) rely on the availability of XML-based markup and metadata in the multimedia flow in order to customize and add value to multimedia content distributed via the Net. In this paper, we present. a general access control model for multimedia information that allows for expressing complex filtering conditions on a wide range of properties of multimedia data. Access control policies' syntax and enforcement is illustrated by applying the model to some of XML-based multimedia data formats for multimedia.

The paper deals with a new technical solution addressed to implement an innovative tools for the sharing data through the web. This new way for the creation of a Web-GIS is based on the SVG (Scalable Vector Graphics), a simple and open web-compliant format, belonging to the XML (eXtensible Markup Language) language-family. This solution allows to access and to share the data in a fast and user-friendly way reducing the time-consuming for the processing and converting data. By means of this application is possible to publish easily GIS applications without giving up the typically functions of GIS software. This "light" solution enables archaeologists (with low computer skills) to perform data-search in a fast and not difficult way without having complex solution on the server-side, neither on client-side.

Abstract The Web is becoming the main information dissemination means in private and public organizations. As a consequence, several applications at both internet and intranet level need mechanisms to support a selective access to data available over the Web. In this context, developing an access control model, and related mechanisms, in terms of XML (eXtensible Markup Language) is an important step, because XML is increasingly used as the language for representing information exchanged over the Web.

Abstract Access control techniques for XML provide a simple way to protect confidential information at the same granularity level provided by XML schemas. In this article, we describe our approach to these problems and the design guidelines that led to our current implementation of an access control system for XML information

The Internet (and networks overall) are currently the core media for data and knowledge exchange. XML is currently the most popular standardization for Web document representation and is rapidly becoming a standard for data representation and exchange over the Internet. One of the main issues is XML documents and in particular, storage and accessing.

XML promoted by the World Wide Web Consortium (W3C) is a de facto standard language for document representation and exchange on the Internet. XML documents may contain private information that cannot be shared by all user communities. Several approaches are designed to protect information in a website. However, these approaches typically are used at file system level, rather than for the data in XML documents that have to be protected from unauthorized access. Usage control has been considered as the next generation access control model with distinguishing properties of decision continuity. In this paper, we present a usage control model to protect information distributed on the web, which allows the access restrictions directly on structures and documents. The model not only supports complex constraints for XML components, such as elements, attributes and datatypes but also provides a mechanism to build rich reuse relationships between models and documents. Finally, comparisons with related works are analysed.

Abstract Web-based applications greatly increase information availability and ease of access, which is optimal for public information. The distribution and sharing of information via the Web that must be accessed in a selective way, such as electronic commerce transactions, require the definition and enforcement of security controls, ensuring that information will be accessible only to authorized entities. Different approaches have been proposed that address the problem of protecting information in a Web system.

Abstract XML (eXtensible Markup Language) has emerged as a prevalent standard for document representation and exchange on the Web. It is often the case that XML documents contain information of different sensitivity degrees that must be selectively shared by (possibly large) user communities. There is thus the need for models and mechanisms enabling the specification and enforcement of access control policies for XML documents.
