The prevalent use of the Internet not only brings with it numerous advantages, but also some drawbacks. The biggest of these problems is the threat to the individual’s personal privacy. This privacy issue is playing a growing role with respect to technological advancements. While new service-based technologies are considerably increasing the scope of information flow, the cost is a loss of control over personal information and therefore privacy. Existing privacy protection measures might fail to provide effective privacy protection in these new environments. This dissertation focuses on the use of new technologies to improve the levels of personal privacy. In this regard the WSP3 (Web Service Model for Personal Privacy Protection) model is formulated. This model proposes a privacy protection scheme using Web Services. Having received tremendous industry backing, Web Services is a very topical technology, promising much in the evolution of the Internet. In our society privacy is highly valued and a very important issue. Protecting personal privacy in environments using new technologies is crucial for their future success. These facts, combined with the detail that the WSP3 model focusses on Web Service environments, lead to the following realizations for the model: The WSP3 model provides users with control over their personal information and allows them to express their desired level of privacy. Parties requiring access to a user’s information are explicitly defined by the user, as well as the information available to them. The WSP3 model utilizes a Web Services architecture to provide privacy protection. In addition, it integrates security techniques, such as cryptography, into the architecture as required. The WSP3 model integrates with current standards to maintain their benefits. This allows the implementation of the model in any environment supporting these base technologies. In addition, the research involves the development of a prototype according to the model. This prototype serves to present a proof-of-concept by illustrating the WSP3 model and all the technologies involved. The WSP3 model gives users control over their privacy and allows everyone to decide their own level of protection. By incorporating Web Services, the model also shows how new technologies can be used to offer solutions to existing problem areas.

This thesis explores the issue of how to reconcile the value of individual privacy with that of freedom of speech. It argues that there ought to be legal protection against invasion of privacy by the media, and that such protection should be seen as complementary to a system of free expression rather than opposed to such a system. A definition of privacy is outlined which, it is contended, meets the criteria for a coherent, neutral definition. Various reasons for valuing privacy and in favour of protecting the individual's reasonable expectations of privacy are identified. It is argued that lack of precision in the normative realm, in defining with certainty when privacy is invaded, should not be an excuse for leaving the individual without legal protection. There follows an examination of the protection of privacy against media incursions in English, New Zealand, Australian and Canadian law, other than the coincidental protection afforded by certain common law actions. There has been significant judicial and legislative recognition of the need to safeguard privacy interests, and many interesting developments in recent years are discussed. However, none of the countries considered has yet developed effective recourse for victims of unwarranted and invasive publications. It is argued that the relationship between privacy and free speech has been wrongly conceptualised, and that in fact both interests serve the same underlying set of values. Problems arise when privacy and free speech interests are balanced in the abstract rather than in context, and when a simplistic view of press freedom is adopted in disregard of the realities of the modern mass media. Invasive publications generally do not significantly advance free speech interests unless they help to provide the information needed for public decision-making. Furthermore, this information can in many cases be conveyed without detriment by withholding details which disclose identity. A three-step test is proposed to determine whether privacy and free speech interests can be reconciled without compromise to either of them, or whether it is necessary to balance these interests in the context of the case. It will also be maintained that a contextual approach is preferable to the adoption of categories such as "public figures" and "public places". These concepts tend to be misleading, and should be eschewed as analytical tools, since they confuse important questions which require separate analysis. / Law, Peter A. Allard School of / Graduate

While on the broadest level this paper argues for a rethinking of governance in our "information society," the central thesis of this paper argues for a national policy for data protection in the private sector. It does so through three sets of lessons from the Quebec data protection experience. These include lessons for I) the policy model, (2) the policy process, (3) the policy area as it relates to the policy problem as well as general questions about governance in an information polity. The methodology for this paper is based on a four-part sequential analysis. The first part is a theoretical and empirical exploration of the problem, which is broadly defined as the "tension over personal information." The second part looks comparatively at how other jurisdictions have responded to the problem. The third part assesses which model is the better policy alternative for Canada and concludes that Quebec regulatory route is better than the national status quo. The fourth part uses a comparative public policy framework, as well as interviews, to understand the policy processes in Quebec and Ottawa so that we can highlight the opportunities and constraints for a national data protection policy in the private sector.
