Title: Addressing the privacy management crisis in online social networks

Abstract: The sharing of personal data has emerged as a popular activity over online social networking sites like Facebook. As a result, the issue of online social network privacy has received significant attention in both the research literature and the mainstream media. Our overarching goal is to improve defaults and provide better tools for managing privacy, but we are limited by the fact that the full extent of the privacy problem remains unknown; there is little quantification of the incidence of incorrect privacy settings or the difficulty users face when managing their privacy. In this talk, I will first focus on measuring the disparity between the desired and actual privacy settings, quantifying the magnitude of the problem of managing privacy. Later, I will propose some technical approaches towards addressing the privacy management crisis.

Speaker Bio: Krishna Gummadi leads the Networked Systems research group at the Max Planck Institute for Software Systems (MPI-SWS) in Germany. He received his Ph.D. (2005) and M.S. (2002) degrees in Computer Science and Engineering from the University of Washington, Seattle. He also holds a B.Tech (2000) degree in Computer Science and Engineering from the Indian Institute of Technology, Madras. Krishna’s research interests are in the measurement, analysis, design, and evaluation of complex Internet-scale systems. His current projects focus on enabling the social Web. Specifically, they include (a) understanding the structure and evolution of social network graphs, (b) understanding how content and information propagates through social networks, (c) leveraging social networks for building better information sharing systems (i.e., better search results and content recommendations as well as filtering unwanted communication and content), and (d) building scalable infrastructures for supporting social networking sites and their workloads. Krishna’s work on online social networks, Internet access networks, and peer-to-peer systems has led to a number of widely cited papers. He also received best paper awards at OSDI, SIGCOMM IMW, and MMCN for his work on Internet measurements and peer-to-peer systems.

Title: Dealing with the digital dilemma – Dodging digital exhaust while delivering trust

Abstract: Managing identity information has long been recognised as being critical to a thriving digital economy. However, many of the solutions developed have created all sorts of security and privacy problems. Solutions have been pursued largely company by company, and government by government in an uncoordinated fashion. Governments, in particular, are starting to realise that going it alone is unproductive and not always in the interests of the individual. Many now see the importance in developing frameworks that can get some consistency and cooperation across governments, including internationally. Furthermore they are seeking, for a range of reasons, including efficiency, consistency and simplification, to involve the private sector.

However, cooperation and interoperability brings with it significant privacy risks. There is major potential for key players in such systems to track and monitor the lives of individuals through not only the identity information itself, but also the ‘digital exhaust’ they leave behind about when, how, and for what purpose they rely on the identity management system.

In response, a commitment to a more user centric approach is emerging that respects privacy. However, implementing these principles in practice is proving to be difficult for a number of reasons. Not least of these is that capitalising on personal information is likely to be a major driver for business involvement in providing the kinds of identity information management services envisaged by these trusted identity frameworks. This presentation will summarise some recent and current initiatives to deliver user centric identity management.

Speaker Bio: Malcolm Crompton is Managing Director of Information Integrity Solutions P/L. He was Australia’s Privacy Commissioner for five years until April 2004. He led the implementation of Australia’s private sector privacy law.

He has advised Australian Government departments and agencies, Australian financial services institutions and many leading global ICT companies on developing trust and delivering privacy to customers. Malcolm has advised APEC on the APEC privacy framework.

He was the Foundation President of iappANZ, the Australia New Zealand affiliate of the International Association of Privacy Professionals (IAPP) and has served on both boards.

He is also a member of the Microsoft Trustworthy Computing Academic Advisory Board and the Reference Groups for a number of EU funded projects, including ABC4Trust. He has sat on international privacy award judging panels. In the previous 20 years, Malcolm held senior executive positions in the Australian Public Service.

Malcolm’s global contribution was recognised when he was awarded the 2012 Privacy Leadership Award by IAPP. His work was also recognised in 2004 when he was awarded the inaugural Chancellor’s Medal for distinguished contribution to the Australian National University.

He has degrees in Chemistry and Economics.
