    eIDeCert: a user-centric solution for mobile identification

    No full text
    The necessity to certify one's identity for different purposes and the evolution of mobile technologies have led to the generation of electronic devices such as smart cards, and electronic identities designed to meet daily needs. Nevertheless, these mechanisms have a problem: they don't allow the user to set the scope of the information presented. That problem introduces interesting security and privacy challenges and requires the development of a new tool that supports user-centrity for the information being handled. This article presents eIDeCert, a tool for the management of electronic identities (eIDs) in a mobile environment with a user-centric approach. Taking advantage of existing eCert technology we will be able to solve a real problem. On the other hand, the application takes us to the boundary of what the technology can cope with: we will assess how close we are to the boundary, and we will present an idea of what the next step should be to enable us to reach the goal

    Quality of Service for Information Access

    Get PDF
    Information is available in many forms from different sources, in distributed locations; access to information is supported by networks of varying performance; the cost of accessing and transporting the information varies for both the source and the transport route. Users who vary in their preferences, background knowledge required to interpret the information and motivation for accessing it, gather information to perform many different tasks. This position paper outlines some of these variations in information provision and access, and explores the impact these variations have on the user’s task performance, and the possibilities they make available to adapt the user interface for the presentation of information

    Digital Image Access & Retrieval

    Get PDF
    The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

    E-City Planning: Geospatial Data Technologies

    The use of new technologies such as ICT (information and communication technologies) is already a reality in several domains of the scientific development. In this context, this paper aims to present an example of the use of ICT in the spatial planning domain at the local level. It is focused on the e-City Planning, based on the example of the municipal master plan, which is the most iconic figure of the planning system framework in Portugal. The conclusions show that the uses of e-platforms and e-City Planning instruments have several advantages, considering the geospatial data technologies. Among these advantages, there is the sharing of knowledge in between local authorities and the citizens in general, who have direct access to the spatial planning contents information, at the distance of a click. With e-City Planning tools and platforms, it is possible to update the planning strategies automatically and therefore, according to the real territory needs, opportunities, and features.info:eu-repo/semantics/publishedVersio

    2017 SCAT (Shoreline Cleanup Assessment Technique) Workshop Report

    On January 18-19, 2017, the Coastal Response Research Center (CRRC) and the National Oceanic and Atmospheric Administration (NOAA) Office of Response and Restoration (ORR) Gulf of Mexico (GOM) Disaster Response Center (DRC) co-sponsored the “Shoreline Cleanup Assessment Technique (SCAT) for Tomorrow” workshop at NOAA’s Disaster Response Center training facility in Mobile, AL. NOAA ORR supports the U.S. Coast Guard (USCG) in its role in emergency response (Emergency Response Division [ERD]) and also overseas damage assessment and restoration (Assessment and Restoration Division [ARD]). As part of its role, ORR updates existing tools and creates new ones related oil spill response, assessment and restoration. This workshop assisted ORR in advancing SCAT with respect to data standards and data exchange. Collecting, managing and sharing SCAT data collected or managed by different organizations can be difficult due to the various data methods and formats used. One of ORR’s major goals is to develop a common data standard for SCAT that is acceptable to federal and state agencies, and industry, and enhancing information sharing

    GIS Application to Support Land Administration Services in Ghana: Institutional Factors and Software Developments

    Get PDF
    In June 1999, the Ghanaian Government launched a new land policy document that sought to address some fundamental problems associated with land administration and management in the country. The document identified the weak land administration system as a particular problem and recommended the introduction of computer-aided information systems in the ‘lands sector’. In 2001, the Government made further proposals to prepare and implement a Land Administration Programme (LAP) to provide a better platform for evolving an efficient land administration that would translate the ‘National Land Policy’ into action. Thus, an up-to-date land information system (LIS), supporting efficient management of land records, is to be constructed, which provides a context for the research reported in this paper. We document two aspects of our research on the adoption of GIS by the Lands Commission Secretariat (LCS) which form part of a pilot project in GIS diffusion. Part one of the paper mainly outlines the empirical results arising from fieldwork undertaken during 2001 to determine the information and GIS requirements of the LCS in relation to their routine administrative processes and to identify the critical factors that are required to ensure that any new GIS applications are successfully embraced. Part two explains the prototype software system developed using ArcView 3.2 and Access that provides the LCS with a means to automate some of the routine administrative tasks that they are required to fulfil. The software has been modified and upgraded following an initial evaluation by LCS employees also conducted as part of the fieldwork in Accra
