Managing identity management systems

Al-sinani, Haitham January 2012 (has links)
Although many identity management systems have been proposed, in- tended to improve the security and usability of user authentication, major adoption problems remain. In this thesis we propose a range of novel schemes to address issues acting as barriers to adoption, namely the lack of interoper- ation between systems, simple adoption strategies, and user security within such systems. To enable interoperation, a client-based model is proposed supporting in- terworking between identity management systems. Information Card systems (e.g. CardSpace) are enhanced to enable a user to obtain a security token from an identity provider not supporting Information Cards; such a token, after en- capsulation at the client, can be processed by an Information Card-enabled relying party. The approach involves supporting interoperation at the client, while maximising transparency to identity providers, relying parties and iden- tity selectors. Four specific schemes conforming to the model are described, each of which has been prototyped. These schemes enable interoperation be- tween an Information Card-enabled relying party and an identity provider supporting one of Liberty, Shibboleth, OpenID, or OAuth. To facilitate adoption, novel schemes are proposed that enable Informa- tion Card systems to support password management and single sign on. The schemes do not require any changes to websites, and provide a simple, intu- itive user experience through use of the identity selector interface. They fa- miliarise users with Information Card systems, thereby potentially facilitating their future adoption. To improve user security, an enhancement to Information Card system user authentication is proposed. During user authentication, a one-time pass- word is sent to the user's mobile device which is then entered into the com- puter by the user. Finally, a universal identity management tool is proposed, designed to support a wide range of systems using a single user interface. It provides a consistent user experience, addresses a range of security issues (e.g. phishing), and provides greater user control during authentication.

Differentiating between collaboration and decision making as predictors of leadership effectiveness : a four nation study

Beech, David Haworth January 2008 (has links)
This thesis addresses conceptual and empirical gaps and confusion in the literature regarding differences between leadership collaboration and decision making and between leadership styles, orientations or methods and dimensions of leadership behaviour. The thesis proposes that the structure of leadership behaviour involves a set of collaboration dimensions and a set of decision making dimensions that have different relationships with effectiveness.

Exploration and evaluation of decision support systems for complex capability acquisition processes in industry

Priestley, Duncan January 2004 (has links)
Recognition of the need to effectively develop and deploy new capability within large BAE SYSTEMS projects has lead to the development of several lifecycle management processes. Many of these processes are generic and open to interpretation, or large and unwieldy. The Capability Development and Deployment Process (COOP) evolved to amalgamate many of these mandatory lifecycIe processes but in doing so became a large complex business process in itself with issues regarding representation, usability and decision making. The hypothesis of this thesis is that a Decision Support System (DSS) could be developed to resolve issues of representation, usability and decision making associated with large complex business processes such as the CDDP. In proving the hypothesis, a 'proof of concept' DSS has been developed and evaluated from 'personal', 'technical' and 'organisational' perspectives as a tool for use by managers that reduces the apparent complexity of the CDDP, bridges islands of knowledge, alleviates bias and misconception, and facilitates the progression of a new capability through development to deployment. Key to the success of the 'proof of concept' DSS was the research methodology and design approach taken, which involved the selection and implementation of appropriate tools and techniques. This included the development of a standardised version of the CDDP using IDEFO modelling format, the development and utilisation of a Bayesian Belief Network in a novel approach to decision support for project maturity, and the development of a graphical user interface to remove the user from the complexity of the CDDP, aid navigation through the process and provide multiple cues to aid decision support. The original paper based version of the CDDP along with the equivalent IDEFO representations are provided on the CD accompanying this thesis. A complete version of the 'proof of concept' Decision Support System could not be supplied due to licensing restriction of the commercialoff- the-shelf (COTS) tools embedded within the application (Systems Architect and Netica). However, the software can be made available for demonstration at Loughborough University on request.

Transaction space : an information based typology of firms

Cook, Peter R. January 2008 (has links)
The research explores the information variety processed in transactions between a firm and its customers, a contingency factor previously ignored in the literature but of increasing importance as businesses focus on customers and technology reduces the cost of information processing. Conceptualizing transactions as Markov chains of business acts the thesis develops, from a theoretical basis in cybernetics, three dimensions (Scale, Diversity & Complexity) which characterise the information variety. These dimensions delineate transaction space within which the firm's position provides a novel typology which integrates a range of structural and strategic theories from the literature, and is hypothesized to explain anomalies in organization design theories. By exaggerating each dimension three ideal type firms are defined and transaction space is operationalized using characteristics of these identified in the literature. On the basis of data collected by survey from a range of business units the research validates the typology and derives a set of theories which describe contingent relationships between the firm's strategy, structure, organisation and information technology and its position in transaction space. The total information variety processed by the firm is found to be bounded, and non-linearly related to business performance allowing the research to posit a cybernetic model of the firm's management processes. The thesis concludes by proposing further ideas which emerge from the application of the transaction space lens to organisation design theory, and suggests further areas for research which may benefit from the transaction space framework. Overall it shows that Transaction space provides both academic researchers and practitioners a framework which unifies theoretical strands, drawn from organisation theory and strategy, which exhibit the influence of the three dimensions and bases ideas about the firm and the way it changes on a so far neglected core aspect of the firm - what it actually does for its customers.
