    BlockChain: A distributed solution to automotive security and privacy

    Full text link
    Interconnected smart vehicles offer a range of sophisticated services that benefit the vehicle owners, transport authorities, car manufacturers and other service providers. This potentially exposes smart vehicles to a range of security and privacy threats such as location tracking or remote hijacking of the vehicle. In this article, we argue that BlockChain (BC), a disruptive technology that has found many applications from cryptocurrencies to smart contracts, is a potential solution to these challenges. We propose a BC-based architecture to protect the privacy of the users and to increase the security of the vehicular ecosystem. Wireless remote software updates and other emerging services such as dynamic vehicle insurance fees, are used to illustrate the efficacy of the proposed security architecture. We also qualitatively argue the resilience of the architecture against common security attacks

    Social Media and Information Overload: Survey Results

    Full text link
    A UK-based online questionnaire investigating aspects of usage of user-generated media (UGM), such as Facebook, LinkedIn and Twitter, attracted 587 participants. Results show a high degree of engagement with social networking media such as Facebook, and a significant engagement with other media such as professional media, microblogs and blogs. Participants who experience information overload are those who engage less frequently with the media, rather than those who have fewer posts to read. Professional users show different behaviours to social users. Microbloggers complain of information overload to the greatest extent. Two thirds of Twitter-users have felt that they receive too many posts, and over half of Twitter-users have felt the need for a tool to filter out the irrelevant posts. Generally speaking, participants express satisfaction with the media, though a significant minority express a range of concerns including information overload and privacy

    This case study is part of six country case study reports that were commissioned in 2003 by the World Bank specifically for the purposes of a summary report on the design and implementation of household targeting systems in the following countries: Chile, Colombia, Costa Rica, Mexico, Brazil and the United States. The report was prepared at the request of officials from the Ministry of Social Assistance. It seeks to examine Brazil's main existing beneficiary registry and selection mechanism. While targeting can effectively channel resources to the poor, implementation details matter tremendously to distributive outcomes. Several key factors affect performance, including: data collection processes; information management; household assessment mechanisms; institutional arrangements; and monitoring and oversight mechanisms. This report conducts an in-depth assessment of key design and implementation factors and their potential impact on outcomes for the household targeting system Cadastro Unico used in Brazil to target social programs to the poor and vulnerable.

    Based on its advanced computing capabilities and ubiquity, the smartphone has rapidly been adopted as a tourism travel tool.With a growing number of users and a wide varietyof applications emerging, the smartphone is fundamentally altering our current use and understanding of the transport network and tourism travel. Based on a review of smartphone apps, this article evaluates the current functionalities used in the domestic tourism travel domain and highlights where the next major developments lie. Then, at a more conceptual level, the article analyses how the smartphone mediates tourism travel and the role it might play in more collaborative and dynamic travel decisions to facilitate sustainable travel. Some emerging research challenges are discussed

    Obama’s election campaign and the integrated use of social\ud media

    Get PDF
    When Barack Obama won the 2008 US Presidential election he\ud did so partly as a result of harnessing the power of social media to\ud communicate with, and enlist the support of, millions of Americans who\ud had never previously been active in the processes of an election campaign.\ud As a result of Obama‘s invitation and his use of new media, some of the\ud poorest members of the world‘s wealthiest nation found themselves able\ud to make a critical contribution through a myriad of small activities starting\ud from seemingly inconsequential choices such as the selection of a mobile\ud phone ring tone. Although ‗people power‘ is not a new force in politics,\ud the Obama campaign set a fresh benchmark for inclusive ways in which to\ud communicate to and with a holistic cross section of the American people,\ud including many who would not have been previously seen as a critical\ud ‗target market‘. This paper examines Obama‘s use of integrated\ud communications and considers the potential implications for other\ud campaigns which may have an inclusion agenda
