    The Value of User-Visible Internet Cryptography

    Full text link
    Cryptographic mechanisms are used in a wide range of applications, including email clients, web browsers, document and asset management systems, where typical users are not cryptography experts. A number of empirical studies have demonstrated that explicit, user-visible cryptographic mechanisms are not widely used by non-expert users, and as a result arguments have been made that cryptographic mechanisms need to be better hidden or embedded in end-user processes and tools. Other mechanisms, such as HTTPS, have cryptography built-in and only become visible to the user when a dialogue appears due to a (potential) problem. This paper surveys deployed and potential technologies in use, examines the social and legal context of broad classes of users, and from there, assesses the value and issues for those users

    Janssen is a manufacturing plant that works in furniture assembly. Component shortages often occurs, it will cause the increase of work in process (WIP) in assembly section. In previous studies, we analyze the root causes with FMEA and then it is resulted that router section is the constraint of the system. There are many non value added activities such as searching and transportation caused by a messy condition of work places and the devices that aren’t put in the right place. The impact is that the time allocated for every change over is higher than before. There are many components that are worked by the router section, so improvements are needed to minimize changes in over time. 5S method and the use of a new design of rack by TRIZ method are suggested for fixing the conditions of work environment. It is expected to eliminate non value added activities and changes in over time. Result shows that we can reduce non value activities in change over of regular components up to 41% and the elimination of this time is 41,6%. The non value activities in changeover of new items is 36,6% and this elimination of time is 53,3%. Key word : change over, kaizen, design, TRIZ metho

    A Novel Application: Using Mobile Technology to Connect Physical and Virtual Reference Collections

    This chapter describes an innovative implementation of the use of iPad kiosks to blur the lines between physical and virtual library collections. Providence College’s Phillips Memorial Library + Commons began lending iPads to students, faculty, and staff in 2012. In addition to lending the devices, library staff dedicated time to learning about both task-based and subject-based mobile applications that would be of use to our community. A small group of library staff tested, discussed, and vetted a variety of apps that would be deployed on the iPads to be lent out. Efforts were made to promote the use and discovery of various apps on the devices through thoughtful organization of the apps on the devices themselves, programming around applications, and the creation of an online research guide designed to teach more about the apps. Despite these initiatives, assessment data from the iPad lending program collected over the course of five semesters suggests that patrons borrowing the iPads are using them primarily for accessing the Internet (Safari, Chrome, etc.), social media (Facebook, Twitter, etc.), and consuming media (YouTube, Netflix, Pandora, Spotify, etc.). With this data in mind, library staff began to think of alternative ways to connect our patrons with useful, content-based, mobile applications. Drawing on research around the Internet of Things and the integration of digital technologies with our physical lives, the Digital Publishing Services Coordinator suggested positioning iPad kiosks strategically within the library’s physical book collection as a means to connect patrons browsing a given area of the stacks with the library’s online resources related to that subject area. The library’s Commons Technology Specialist had experience with iPad kiosks and programming the iPads as he had managed the logistics of the iPad lending program since its inception. Working collaboratively, these colleagues devised a way to image the iPads for public use and load them with subject-specific apps as well as links to library databases and open web resources. The team chose to use Scalar as the primary content management tool for kiosk content. This chapter provides details about the selection and deployment of content for the Theology Kiosk, signage and communications created to attract patrons to the kiosk, and initial data about kiosk use. The piece concludes with a review of the kiosk project and an outline of future planning related to the project (staff time, hardware and software requirements, usability testing, scaling the project, etc.)

    JOHANNESBURG METRO POLICE DEPARTMENT (JMPD) FINESONLINE.CO.ZA TRAFFIC FINE SYSTEM

    The Johannesburg Metro Police Department (JMPD) Finesonline.co.za system aims to serve as part of a company called 2Big Mobile's Integrated Information System (I2MS), a five-part project, of which three phases have now been implemented by the Johannesburg Metro Police Department. The system seeks to offer Johannesburg motorists the chance to search for and view details of their fines, thus allowing motorists to verify their fines by viewing online pictures from speed and red light cameras as well as give them the opportunity to query and or contest the summons or warrant(s). There are far too many people issued with traffic fines daily on South African roads throughout the country. There are also equally as many if not more motorists who are arrested on a daily basis because of unpaid fines; but are reluctant to pay because they do not have the time to stand in winding queues at traffic departments or local municipalities to do it. At the moment, if a motorist wants to check traffic camera photos they have to visit the traffic department in person, sometimes more than once. That is very inconvenient and usually impossible for people who were a long way from home when they incurred the fine. There is only one main municipal court in the Johannesburg CBD that handles traffic fines as well as all the other by-laws contraventions, and hears many cases daily. This leads to reluctance of offenders to contest/query their fine which ultimately leads to more offenders neglecting their sununonses/warrants; which in turn leads to more motorists being arrested at roadblocks. Many researchers have found that E-commerce and usability issues are inextricably linked, since unusable E-commerce sites are often also unsuccessful. It has been discovered that usability plus security issues are the major setbacks to a lot of E-Commerce website in South Africa. Through this project, the author aspires to discover ways to achieve this fourth phase of the JMPD project by developing a website that will facilitate a good and up to date database system which allows for good capturing of data, including images, a sound search capability; being able to retrieve the correct fine/warrant with its relevant and corresponding information for that specific user together with the images of the offense. Lastly, the system should, provide a means to or act as an intermediary between the Johannesburg traffic department and the mnnicipal court to facilitate simpler and specialized querying of fines and or warrants. While striving to achieve, this, the system should also be usable and secure meeting nniversal E-Commerce standards. The system was developed in accordance with System Development Life Cycle (SDLC) ; comprising Analysis phase, Requirements Specification phase, Designing phase, Implementation and Testing, all following Royce's Final Model of the Waterfall Model with the output of each phase serving as the input in the subsequent phase, allowing jumping back and forth between phases to accommodate changing requirements. The selection of tool for this system was done without compromise to ensure that all the objectives of the system would be met and the successful development of the JMPD Finesonline.co.za realised. In conclusion, the JMPD Finesonline.co.za System will be a solution for the problems faced with the current manual system. It will therefore enhance service delivery on the part of the JMPD as well as the mnnicipal courts by better serving South African citizens efficiently and conveniently

    Search Engine Optimisation in UK news production

    This is an Author's Accepted Manuscript of an article published in Journalism Practice, 5(4), 462 - 477, 2011, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/17512786.2010.551020.This paper represents an exploratory study into an emerging culture in UK online newsrooms—the practice of Search Engine Optimisation (SEO), which assesses its impact on news production. Comprising a short-term participant observational case study at a national online news publisher, and a series of semi-structured, in-depth interviews with SEO professionals at three further UK media organisations, the author sets out to establish how SEO is operationalised in the newsroom, and what consequences these practices have for online news production. SEO practice is found to be varied and application is not universal. Not all UK news organisations are making the most of SEO even though some publishers take a highly sophisticated approach. Efforts are constrained by time, resources and management support, as well as off-page technical issues. SEO policy is found, in some cases, to inform editorial policy, but there is resistance to the principal of SEO driving decision-making. Several themes are established which call for further research
