“…Identity managers [Jendricke and Gerd tom Markotten 2000;Clauß and Köhntopp 2001;Berthold and Köhntopp 2001] are envisaged high-level mechanisms that assist users in managing their privacy online. They are based on some underlying anonymous communication infrastructure, like the one that was described in this article.…”

User-adaptive applications cater to the needs of each individual computer user, taking for example users' interests, level of expertise, preferences, perceptual and motoric abilities, and the usage environment into account. Central user modeling servers collect and process the information about users that different user-adaptive systems require to personalize their user interaction.Adaptive systems are generally better able to cater to users the more data their user modeling systems collect and process about them. They therefore gather as much data as possible and "lay them in stock" for possible future usage. Moreover, data collection usually takes place without users' initiative and sometimes even without their awareness, in order not to cause distraction. Both is in conflict with users' privacy concerns that became manifest in numerous recent consumer polls, and with data protection laws and guidelines that call for parsimony, purpose-orientation, and user notification or user consent when personal data are collected and processed.This article discusses security requirements to guarantee privacy in user-adaptive systems and explores ways to keep users anonymous while fully preserving personalized interaction with them. User anonymization in personalized systems goes beyond current models in that not only users must remain anonymous, but also the user modeling system that maintains their personal data. Moreover, users' trust in anonymity can be expected to lead to more extensive and frank interaction, hence to more and better data about the user, and thus to better personalization. A reference model for pseudonymous and secure user modeling is presented that meets many of the proposed requirements.

“…The importance of management is concluded in validating established profiles, and rights in the relations (Casassa et al, 2002). The information can be used in process related with identity management (Koch and Wörndl, 2001;Berthold and Köhntopp, 2001) or security mechanisms (Clifford, 1995).…”

“…Identity management system maintains the privacy not only on his/her digital identity, but genuine identity too. Another advantage is the control over digital identities in terms of authenticity, lifecycle and validity (Berthold and Köhntopp, 2001). The main use of GI's information is to create accounts (figure 1).…”

The identity is a unique and intransitive property which any human being possesses. Due to its characteristics is used in Internet. Unfortunately, when a user discloses his personal information to web site does not know the risks about his identity's privacy. This paper describes the usefulness of user's identity in Internet and the problems related with their usage in web sites. To improve the user's privacy we propose a digital pseudonym identity as an alternative to replace the used of genuine identity in Internet.

“…Dazu gibt es verschiedene Ansätze in Wirtschaft und Forschung, die sich dadurch unterscheiden, wie feingranular diese Daten verwaltet werden können, wo diese Daten gespeichert und welche Sicherheitsmechanismen integriert werden. Sie können zudem einen unterschiedlichen Fokus setzen: entweder optimaler Datenschutz(Berthold & Köhntopp 2000) oder die bestmögliche Repräsentation einer Online-Identität(Koch 2002), wobei ein ideales Identitätsmanagementsystem beides vereinen sollte. Im Rahmen des Projektes onefC der Universität Hamburg entsteht ein Identitätsmanagementsystem, welches als Hauptmotivation die Selbstdarstellung der Internetnutzer sieht, jedoch auch großen Wert auf Sicherheitsaspekte legt…”

Die Benutzer des World Wide Webs werden regelmäßig mit seinen vielfältigen Benutzbarkeitsproblemen konfrontiert. Ein gravierender Mangel liegt dabei darin, dass es bis heute kaum brauchbare Konzepte zur Individualisierung der im Web angebotenen Informationen und Dienste gibt, die auch siteübergreifend einsetzbar wären: Suchmaschinen bieten keine personalisierten Ausgaben, Links sind nur durch die Autoren eines Dokuments zu erstellen und Annotationstechniken konnten sich bis heute nicht durchsetzen. Dieses Paper stellt ein neues Konzept von Social Navigation vor, das eine Identitätsinfrastruktur verwendet, um auch global einsetzbar zu sein und typischer Probleme wie des Kaltstartproblems oder des Sparsity-Problems Herr zu werden. Durch eine Identitätsinfrastruktur werden die sozialen Aspekte der Internetnutzung betont und die Voraussetzungen für soziales Navigieren verbessert. Es wird ein Prototyp vorgestellt, der diese Konzepte in Teilen realisiert. Abschließend werden die Ergebnisse einer damit durchgeführten Benutzbarkeitsevaluation diskutiert.
