DESCRIPTION:Online Social Networks like Facebook\, MySpace\, Xing\, etc. h
 ave become extremely popular. Yet they have some limitations that we want 
 to overcome for a next generation of social networks: privacy problems and
  requirements of Internet connectivity\, both of which are due to web-base
 d applications on a central site whose owner has access to all data.\n\nTo
  overcome these limitations\, we envision a paradigm shift from client-ser
 ver to a peer-to-peer infrastructure coupled with encryption so that users
  keep control of their data and can use the social network also locally\, 
 without Internet access. This shift gives rise to many research questions 
 intersecting networking\, security\, distributed systems and social networ
 k analysis\, leading to a better understanding of how technology can suppo
 rt social interactions. \n\nOur project\, PeerSoN\, consists of several pa
 rts. One part is to build a peer-to-peer infrastructure that supports the 
 most important features of online social networks in a distributed way. We
  have written a first prototype to test our ideas. Another part is concern
 ed with encryption\, key management\, and access control in such a distrib
 uted setting. Extending the distributed nature of the system\, we investig
 ate how to integrate such peer-to-peer social networking with ubiquitous c
 omputing and delay-tolerant networks\, to enable direct exchange of inform
 ation between devices and to take into account local information. http://w

 Deutsche Telekom Laboratories\, Berlin. In 2005 and 2006\, she was a post-
 doctoral scholar at the University of California at Berkeley\, School of I
 nformation. She received her Ph.D. in Communication Systems from EPFL\, Sw
 itzerland\, in 2004\, a graduate degree in Computer Science in 1999\, and 
 undergraduate degrees in Computer Science in 1996 and in Business Administ
 ration in\n1995 from the University of Klagenfurt\, Austria. In 2003 and 2
 004 she was a research and teaching assistant at EPFL and from 1999 to 200
 3 she worked at the IBM Zurich Research Laboratory in the Network Technolo
 gies Group. Her current research interests are economics\, security\, and 
 privacy of self-organized networks.\n\n
