This essay critically examines some classic philosophical and legal theories of privacy, organized into four categories: the nonintrusion, seclusion, limitation, and control theories of privacy. Although each theory includes one or more important insights regarding the concept of privacy, I argue that each falls short of providing an adequate account of privacy. I then examine and defend a theory of privacy that incorporates elements of the classic theories into one unified theory: the Restricted Access/Limited Control (RALC) theory of privacy. Using (...) an example involving data-mining technology on the Internet, I show how RALC can help us to frame an online privacy policy that is sufficiently comprehensive in scope to address a wide range of privacy concerns that arise in connection with computers and information technology.

Theory in the traditional sense of the word comprises a deductive system in which hypotheses and their logical consequences are compared with empirical observations. Such comparison is usually regarded as a verification of the theory. The ideal for this conception of theory is a universal scientific system in which the theories of the different scientific disciplines are brought together under the head of a few fundamental principles.Traditional theory and reality belong to two distinct and separate provinces. Insofar as men make (...) forecasts with the help of theory and attempt to change reality, they do not act as theoreticians. Theory remains in the realm of contemplation. Philosophers have frequently made something absolute out of this aspect of theory and, under the title of,logosf or.spirit', have deified the subject of these intellectual activities. It appears in their systems as the creator of the world. What they are really doing, however, is treating the scholar’s activity, which is based on the division of labor in modern society, as an dbjective and independent substance. The real subject of theory in its traditional aspect is not pure spirit but the scholar who performs definite and necessary functions in modem society.If such an analysis is accepted, the philosophical naiveté of the theoretician disappears. He perceives that not only thinking as such, but also its task, its direction, and the structure of the objective world are ultimately connected with human activity and work. Out of the historical process by which men wrest their living from nature, there emerges the separation of material and intellectual work, as well as the structure and the content of the latter. The dogmatic differentiation between the logical and historical premises of science cannot be maintained. The theoretician is himself part and parcel of the subject which forms the real objective world. To take an active part in the direction of the social life of humanity, therefore, becomes a function and a requirement of science.So it is as theory, in the critical sense of the word, that the author regards the type of reasoning which attempts to impart to social life in its totality a rational form and which does not limit itself to working within the framework of the given system of the division of labor. The history of different scientific theories shows theory, with its unity and clarity, in contrast and opposition to the heterogeneity and disharmony of the real world. In the attempts to achieve harmony in society, thought may play an important role.The author analyses the logical structure of critical theory in the performance of such a function. Its content is the description of present society in terms of a development towards a rational form. Critical theory, therefore, always remains intimately linked up with the reality of existence. It needs for its development in each and every instance the existence and assistance of the various scientific disciplines. Its logical structure, however, is more complicated than that of theory in the traditional sense, because it does not regard its objectives as a separate and foreign province. Science, in the traditional sense, even where it formulates developments in nature and human history, regards interests and purposes as given facts and guideposts that are foreign to its own structure. It has a utilitarian character in a directly understandable sense. Critical theory, however, is confronted with the task of justifying its own problems and their differentiation and has to adjust its internal structure accordingly. It does not set up an unchanging system but sees as its purpose the attempt to apply the knowledge that has been accumulated in the traditional theories to the social totality in the direction that critical theory itself indicates.La théorie, au sens traditionnel, est un système déductif. La confrontation des connaissances obtenues par voie déductive avec les faits constatés permet la vérification de la théorie. L'idéal est un système universel de la science dans lequel les théories des différentes disciplines, toutes ensemble, sont rattachées à un petit nombre de propositions premières.La réalité demeure extérieure à une théorie ainsi conçue. Dans la mesure où les hommes utilisent la théorie pour faire des prévisions et pour modifier la réalité, ils ne sont plus des théoriciens. En ce sens, la théorie est purement contemplative. Les philosophes qui ont analysé la connaissance ont souvent porté à l'absolu cet aspect de la théorie et ont fait du sujet des opérations intellectuelles, sous les noms de,Logos4 ou de,Esprit4, le démiurge du monde. En vérité, ils ont ainsi hypostasié l'activité, qui dans la société moderne revient au savant du fait de la division du travail. Le sujet réel de la théorie sous sa forme traditionnelle, loin d'être l'esprit pur, est le savant qui remplit dans la société bourgeoise une fonction nécessaire, bien déterminée.Après cette prise de conscience, la naïveté philosophique du théoricien doit disparaître. Il comprend que la pensée, ses tâches et son orientation, l'organisation du monde qui lui est donné, se ramènent en dernière analyse au travail humain. Le combat de l'homme avec la nature est la condition de l’évolution historique, dans laquelle le travail matériel se sépare du travail intellectuel, il détermine la structure et le contenu de ce dernier. La séparation rigide des hypothèses logiques et historiques de la science est impossible à maintenir. L'activité du théoricien exprime le sujet concret qui ne donne pas forme à la seule théorie, mais aussi au monde réel. Prendre position dans la vie sociale, l'influencer consciemment devient une tâche immanente à la science.Par théorie au sens critique, H. entend la connaissance qui ne se contente pas de construire ses systèmes en respectant les cadres de la division du travail existante, mais qui s'efforce de donner à la totalité sociale une forme raisonnable. Dans l'histoire, la cohérence logique et comme transparente qui caractérise les théories traditionnelles, était en contradiction avec les rapports réels. Dans les tentatives pour rendre la société conforme à l'harmonie de la pensée, celle-ci peut jouer un rôle important.H. étudie la structure logique que présente la pensée lorsqu'elle exerce une telle fonction. Elle a pour contenu la représentation de la société actuelle, envisagée par rapport à révolution vers la raison. La théorie critique forme par conséquent un jugement existentiel unique. Pour développer et justifier celui-ci, elle a besoin, à chaque instant, de la science spéciale. Mais comme la théorie ne conçoit pas les buts qu'elle s'assigne comme extérieurs à elle, elle est logiquement plus compliquée que la théorie traditionnelle. Même lorsque la discipline spéciale construit des évolutions comme dans l'histoire naturelle et humaine, elle est orientée par des objectifs et des intérêts. Elle est, en un sens immédiatement compréhensible, utile. La théorie critique, au contraire, doit justifier elle-même la manière dont elle pose les problèmes, qui d'ailleurs sans cesse se transforment, elle doit modifier en conséquence l'ordre de son développement. Elle ne travaille pas en vue d'un système fixe, mais se comprend elle-même comme une tentative pour appliquer le savoir accumulé par les théories traditionnelles, à la marche historique de l'ensemble social, afin d'exercer une action dans un sens bien déterminé.Aussi bien, cette fonction de la théorie est-elle la réalisation des intentions authentiques de la philosophie idéaliste classique.

This paper presents some results of a case study of the usage of the social networking platform studiVZ by students in Salzburg, Austria. The topic is framed by the context of electronic surveillance. An online survey that was based on questionnaire that consisted of 35 (single and multiple) choice questions, 3 open-ended questions, and 5 interval-scaled questions, was carried out (N = 674). The knowledge that students have in general was assessed with by calculating a surveillance knowledge index, the critical (...) awareness towards surveillance by calculating a surveillance critique index. Knowledge about studiVZ as well as information behaviour on the platform were analyzed and related to the surveillance parameters. The results show that public information and discussion about surveillance and social networking platforms is important for activating critical information behaviour. In the case of studiVZ, a change of the terms of use in 2008 that brought about the possibility of targeted personalized advertising, was the subject of public discussions that influenced students’ knowledge and information behaviour.

The paper begins with a defence of a new definition of privacy as the absence of undocumented personal knowledge. In the middle section, I criticise alternative accounts of privacy. Finally, I show how my definition can be worked into contemporary American Law.
