Transparent authentication methodology in electronic education
No full textIn the context of on-line assessment in e-learning, a problem arises when a student taking an exam may wish to cheat by handing over personal credentials to someone else to take their place in an exam, Another problem is that there is no method for signing digital content as it is being produced in a computerized environment. Our proposed solution is to digitally sign the participant’s work by embedding voice samples in the transcript paper at regular intervals. In this investigation, we have demonstrated that a transparent stenographic methodology will provide an innovative and practical solution for achieving continuous authentication in an online educational environment by successful insertion and extraction of audio digital signatures
Approaches to maintaining provenance throughout the additive manufacturing process
Get PDFThe development of 3D printers has resulted in significant Intellectual Property Right issues. This work presents a model for signing printable 3D objects. The paper initially reviews the security principles of signing of objects in both digital or physical form, and the metrics for assessing signatures. 3D designs are not just a file, but actual physical objects and should be treated identically, to digital documents that have associated intellectual property rights and copyright protection. In this paper we propose a signing methodology intended to resolve issues with the adaptation of rapid prototyping and 3D printing by users both in engineering and the humanities. The proposed digital signing methodology is based on physical signing principles that follow archival principles to maintain accurate records. The new model allows the transition of provenance between digital and physical form

Provenance framework for additive manufacturing
No full textAdvances in additive manufacturing have had a disruptive influence to the conventional manufacturing process by bringing manufacturing to the hands of the customer and shortening the supply chain. The customer can customise and manufacture any 3D object using additive manufacturing without leaving their office, lab or home. This paradigm shift in manufacturing raised concerns about the intellectual property rights of 3D objects. At the moment additive manufacturing has allowed owners of 3D printers to fabricate any 3D object with no accountability and no provenance measures for the original authors of the 3D objects. This is a problem because licensing usually allows for limited use and provenance reflects the value of the 3D object. This work presents a framework for provenance of 3D objects that investigates the transition of security properties from digital 3D objects to 3D printed objects because of the absence of such mechanisms. A wholistic security view of additive manufacturing process by presenting a additive manufacturing security reference model and a tool to benchmark security of additive manufacturing. This framework is intended to facilitate for the industry with the adaptation of 3D printing by engineers, designers and other types of users. The proposed framework is based on digital security measures, physical signing principles and following archival principles to maintain accurate records because of the nature of the transition of properties from digital to analogue records. The proposed framework has the potential of pushing 3D printing adaptation thought sharing and exchange of 3D objects by public and academic domain by using our security framework as enabling technology.The security reference model for additive manufacturing is intended to provide security by design for any additive manufacturing process, this reference model also covers the cyber to physical security aspect of additive manufacturing.The benchmarking tool provides a security measure that is flexible and is tailored fit assessment process to any additive manufacturing workflow, it give freedom to security practitioners to fit it to any organisation structure to report on the organisation state of security
Transparent authentication in e-learning
No full textIn the context of on-line assessment in e-learning a problem arises is that someone taking an exam may wish to cheat by handing over personal credentials to someone to take their place in an exam. This differs from authenticating for on-line banking where it is in the user interest to ensure safe and correct authentication. Our proposed solution is to digitally sign the student work by embedding voice samples in the exam paper at regular intervals. In this investigation we have demonstrated that transparent steganography can provide an effective mechanism for achieving such a good goa
Charity accountability: evidence from the United Kingdom (UK)
No full textThis thesis examines UK charities’ accountability through the use of annual reports and annual reviews as formal accountability tools. The overall aim of the thesis is to undertake a coherent analysis of the accountability of annual reports and annual reviews using multiple dimensions of text and disclosures by empirically examining UK charities’ accountability disclosure. Given the overall aim, the objectives of this thesis are: first, to assess the effectiveness of narrative communication textual characteristics - specifically chairman’s statements - in the context of the role played by trustees in delivering charity accountability; second, to examine the determinants of the extent of performance disclosures in the top 100 UK fundraising charities; and third, to investigate narratives’ disclosure trends, strategies and rationales in the annual reports by Kids Company to communicate its performance and activities over time and around critical events, until its final collapse and leaders cognitive behavioural traits (e.g., hubris) impact on disclosures. Systematic engagement with the literature surrounding charities’ accountability helps to identify the problems and highlights the knowledge gaps in discharging accountability through public discourse. Three different theoretical frameworks are used to develop and address the research questions of the thesis: stakeholder theory, resource dependence theory, legitimacy theory and hubris. Due to the nature of the research questions and the theoretical framework, the underpinning philosophy for this study is pragmatism. The research outcome of the first paper revealed that charities tend to behave instrumentally when preparing chairman’s statements to cover both bad and good news, but charities still reflect some ethical sense by adopting a felt accountability by prioritising internal accountability. The second paper showed that the overall level of the Performance Disclosure Index (PDI) remains weak with a high emphasis on input and output information and less focus on efficiency, outcome and effectiveness disclosures. Moreover, there have been shifts in the influence of resource providers and stakeholders on the level of charity accountability. The third paper revealed that positive and uncertainty words (frequencies) dominated the narrative disclosures, while more positive performance news was emphasised using hyperbole words. It was found that the charity responded to external concerns either reactively or proactively. Finally, informed by hubris literature, it is indicated that the most common form of hubris found in the CEO statements was overconfidence and attribution of performance to self. Overall, this thesis contributed to the field on a number of different levels - theoretical, methodological and contextual - as well as informing policy and practical implications by providing a multi-layered understanding of the charity accountability phenomenon within the UK context.<br/
