    Secure Mobile Social Networks using USIM in a Closed Environment

    Online social networking and corresponding mobile based applications are gaining popularity and now considered a well-integrated service within mobile devices. Basic security mechanisms normally based on passwords for the authentication of social-network users are widely deployed and poses a threat for the user security. In particular, for dedicated social groups with high confidentiality and privacy demands, stronger and user friendly principles for the authentication and identification of group members are needed. On the other hand, most of the mobile units already provide strong authentication procedures through the USIM/ISIM module. This paper explores how to build an architectural framework for secure enrollment and identification of group members in dedicated closed social groups using the USIM/SIM authentication and in particular, the 3GPP Generic Authentication Architecture (GAA), which is built upon the USIM/SIM capabilities. One part of the research is to identify the marketable use-cases with corresponding security challenges to fulfill the requirements that extend beyond the online connectivity. This paper proposes a secure identification design to satisfy the security dimensions for both online and offline peers. We have also implemented an initial proof of the concept prototype to simulate the secure identification procedure based on the proposed design. Our implementation has demonstrated the flexibility of the solution to be applied independently for applications requiring secure identification

    Using technology in service delivery to families, children and young people

    This paper provides an overview of how the innovative use of technology can add value to service delivery in organisations working with families, children and young people.Key messages:Most Australians have access to the Internet and use mobile devices to connect from anywhere, at any time. Research suggests that even isolated and marginalised groups are using technology in their everyday lives.For some groups (e.g., young people), technology may be their preferred method of communication.There appears to be a difference between how people are using the Internet (regularly, from anywhere, connecting with social networks, investigating services) and how some organisations are engaging with it (infrequently, in one direction).Technology works best when used to augment or improve existing services for clients, or to offer innovative approaches to existing services.Technology can be used in diverse ways for organisational improvement (e.g., remote access, staff training, professional development) or client services (e.g., online counselling, SMS appointment reminders, access to resources).Using technology does not necessarily involve large monetary investments or reinventing the wheel in terms of policy and procedures. Often it is a matter of adapting and refining existing services and policies to better suit the online world.Incorporating technology into services takes time, and will need continued assessment and refinement to be successful

    Webliography of African-American Champaign-Urbana

    This Lab Note reflects one part of a year-long project called eBlackChampaign-Urbana. Our interest here is to provide better access to the dispersed documentation of local African-American history and culture in ChampaignUrbana, using digital technology to aggregate and enliven historical and contemporary information. Although this webliography focuses primarily on substantial, in-depth texts documenting local African-American life, we are also aggregating into the eBlackCU.net website URLs for local African-American websites, facebook pages, photographs, newspaper clippings, flyers, posters and other ephemeral documentation of Champaign-Urbana's Black heritage.published or submitted for publicationnot peer reviewe

    Delivering elder-care environments utilizing TV-channel based mechanisms

    In this paper, we present a smart environment for elderly. What makes the development of such system challenging is that the concept of smartness for elderly brings to the extreme the idea of invisibility of the technology. In our experience, elders are well-disposed to new technologies, provided that those will not require significant changes - namely, they are invisible - to their habits. Starting from this consideration, 200 caregivers responses were collected by questionnaire, so as to better understand elders' needs and habits. A system was subsequently developed allowing elders to access a number of "modern web services" as standard TV channels: at channel 43 there is the health status, at channel 45 the photos of the family, at 46 the agenda of the week, just to mention few of the available services. The content of such services is automatically generated by the smart devices in the environment and is managed by the caregivers (e.g., family members) by simple web apps. Fourteen families were asked to install the system in their house. The results of these experiments confirm that the proposed system is considered effective and user-friendly by elders

    An active, ontology-driven network service for Internet collaboration

    No full text
    Web portals have emerged as an important means of collaboration on the WWW, and the integration of ontologies promises to make them more accurate in how they serve users’ collaboration and information location requirements. However, web portals are essentially a centralised architecture resulting in difficulties supporting seamless roaming between portals and collaboration between groups supported on different portals. This paper proposes an alternative approach to collaboration over the web using ontologies that is de-centralised and exploits content-based networking. We argue that this approach promises a user-centric, timely, secure and location-independent mechanism, which is potentially more scaleable and universal than existing centralised portals
