Collaborative Fraud Detection in Outsourcing Scenarios: Issues of and Solutions for Privacy and Confidentiality

Authors: Ulrich Flegel, Florian Kerschbaum, and Richard Wacker

Published in: Dagstuhl Seminar Proceedings, Volume 8302, Countering Insider Threats (2008)


Abstract
In this paper we investigate the privacy dimension of collaborative fraud detection envisioned for outsourcing scenarios. Firstly, we investigate the privacy requirements derived from privacy law and present the resulting judicial argument for pseudonymizing audit data generated for the purpose of fraud detection. Second, we summarize the requirements for such pseudonymization derived from the requirements of the misuse detection approach for fraud detection. Third, we describe our approach for pseudonymization of audit data and two approaches for hiding timestamps in audit data.

Fraud Detection from a Business Perspective: Future Directions and Challenges

Authors: Ulrich Flegel, Julien Vayssière, and Gunter Bitz

Published in: Dagstuhl Seminar Proceedings, Volume 8302, Countering Insider Threats (2008)


Abstract
This contribution summarizes the state of the art of fraud detection in practice and shows the relations between the technology for fraud detection and intrusion detection. We identify prospective directions for further investigation and imminent challenges.

7. 08102 Working Group – Intrusion and Fraud Detection for Web Services

Authors: Marc Daciér, Ulrich Flegel, Ralph Holz, and Norbert Luttenberger

Published in: Dagstuhl Seminar Proceedings, Volume 8102, Perspectives Workshop: Network Attack Detection and Defense (2008)


Abstract
Web services (WS) technology bears the promise to finally bring the power of SOA middleware to the road on a large scale and across organizational domains. Big players such as Google, Amazon, SAP, and IBM have already adopted the technol-ogy. European funding agencies are strongly believing and heavily investing into WS-related technological developments and application scenarios. We expect a growing adoption and widespread use of Web services for different application areas, among them e.g. value added service composition, Web 2.0-enhanced communication sys-tems (e.g. based on Ajax), and focused service offerings from specialized small or medium sized enterprises (SMEs).
