Developing a Framework to Implement Public Key Infrastructure Enabled Security in XML Documents

This paper concentrates on proposing a framework to implement the PKI enables security in XML documents, by defining a common framework and processing rules that can be shared across applications using common tools, avoiding the need for extensive customization of applications to add security. The Framework reuses the concepts, algorithms and core technologies of legacy security systems while introducing changes necessary to support extensible integration with XML. This allows interoperability with a wide range of existing infrastructures and across deployments. Currently no strict security models and mechanisms are available that can provide specification and enforcement of security policies for XML documents. Such models are crucial in order to facilitate a secure dissemination of XML documents, containing information of different sensitivity levels, among (possibly large) user communities

DTD level authorization in XML documents with usage control

[Summary]: In recent years an increasing amount of semi-structured data has become important to humans and programs. XML promoted by the World Wide Web Consortium (W3C) is rapidly emerging as the new standard language for semi-structured data representation and exchange on the Internet. XML documents may contain private information that cannot be shared by all user communities. So securing XML data is becoming increasingly important and several approaches have been 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. Usage control has been considered as the next generation access control model with distinguishing properties of decision continuity. Usage control enables finer-grained control over usage of digital objects than that of traditional access control policies and models. In this paper, we present a usage control model to protect information distributed on the web, which allows the access restrictions directly at DTD-level and XML document-level. Finally, comparisons with related works are analysed

CWRML: representing crop wild relative conservation and use data in XML

Background Crop wild relatives are wild species that are closely related to crops. They are valuable as potential gene donors for crop improvement and may help to ensure food security for the future. However, they are becoming increasingly threatened in the wild and are inadequately conserved, both in situ and ex situ. Information about the conservation status and utilisation potential of crop wild relatives is diverse and dispersed, and no single agreed standard exists for representing such information; yet, this information is vital to ensure these species are effectively conserved and utilised. The European Community-funded project, European Crop Wild Relative Diversity Assessment and Conservation Forum, determined the minimum information requirements for the conservation and utilisation of crop wild relatives and created the Crop Wild Relative Information System, incorporating an eXtensible Markup Language (XML) schema to aid data sharing and exchange. Results Crop Wild Relative Markup Language (CWRML) was developed to represent the data necessary for crop wild relative conservation and ensure that they can be effectively utilised for crop improvement. The schema partitions data into taxon-, site-, and population-specific elements, to allow for integration with other more general conservation biology schemata which may emerge as accepted standards in the future. These elements are composed of sub-elements, which are structured in order to facilitate the use of the schema in a variety of crop wild relative conservation and use contexts. Pre-existing standards for data representation in conservation biology were reviewed and incorporated into the schema as restrictions on element data contents, where appropriate. Conclusion CWRML provides a flexible data communication format for representing in situ and ex situ conservation status of individual taxa as well as their utilisation potential. The development of the schema highlights a number of instances where additional standards-development may be valuable, particularly with regard to the representation of population-specific data and utilisation potential. As crop wild relatives are intrinsically no different to other wild plant species there is potential for the inclusion of CWRML data elements in the emerging standards for representation of biodiversity data

DRIVER Technology Watch Report

This report is part of the Discovery Workpackage (WP4) and is the third report out of four deliverables. The objective of this report is to give an overview of the latest technical developments in the world of digital repositories, digital libraries and beyond, in order to serve as theoretical and practical input for the technical DRIVER developments, especially those focused on enhanced publications. This report consists of two main parts, one part focuses on interoperability standards for enhanced publications, the other part consists of three subchapters, which give a landscape picture of current and surfacing technologies and communities crucial to DRIVER. These three subchapters contain the GRID, CRIS and LTP communities and technologies. Every chapter contains a theoretical explanation, followed by case studies and the outcomes and opportunities for DRIVER in this field

A Study on the Open Source Digital Library Software's: Special Reference to DSpace, EPrints and Greenstone

The richness in knowledge has changed access methods for all stake holders in retrieving key knowledge and relevant information. This paper presents a study of three open source digital library management software used to assimilate and disseminate information to world audience. The methodology followed involves online survey and study of related software documentation and associated technical manuals.Comment: 9 Pages, 3 Figures, 1 Table, "Published with International Journal of Computer Applications (IJCA)

THE OPTIMIZATION OF THE INTERNAL AND EXTERNAL REPORTING IN FINANCIAL ACCOUNTING: ADOPTING XBRL INTERNATIONAL STANDARD

More and more enterprises, especially the listed companies, have adopted newaccounting norms and regulations (IFRS or US GAAP, Bale II and, in perspective, SURFI),manifesting interest for publishing financial reports using a standard format able to considerablyimprove their communication, data collection in the receiving units, control and analysis offinancial information. When switching to the new accounting rules specified in international orregional standards and norms, regulatory and control bodies recommend the XBRL format forfinancial reporting, with recognition of the regional jurisdiction. Our paper makes a review of theliterature, presents the XBRL specific elements and proposes possible solutions for internal andexternal financial reporting of an enterprise. Finally, it concludes on the benefits of adopting XBRLat national level in a potential XBRL Romania project.accounting norms, financial reporting, XBRL, taxonomy, XBRL jurisdiction.

Safe Data Sharing and Data Dissemination on Smart Devices

The erosion of trust put in traditional database servers, the growing interest for different forms of data dissemination and the concern for protecting children from suspicious Internet content are different factors that lead to move the access control from servers to clients. Several encryption schemes can be used to serve this purpose but all suffer from a static way of sharing data. In a precedent paper, we devised smarter client-based access control managers exploiting hardware security elements on client devices. The goal pursued is being able to evaluate dynamic and personalized access control rules on a ciphered XML input document, with the benefit of dissociating access rights from encryption. In this demonstration, we validate our solution using a real smart card platform and explain how we deal with the constraints usually met on hardware security elements (small memory and low throughput). Finally, we illustrate the generality of the approach and the easiness of its deployment through two different applications: a collaborative application and a parental control application on video streams
