DESCRIPTION:While managing a user's personal data (photos\, contacts\, mus
 ic collection\, etc.) with online service providers like Facebook\, Google
 \, or Yahoo offers many advantages\, it is not without its drawbacks: a lo
 ss of privacy and control\, lock-in\, and vulnerability to provider failur
 es due to attacks or insolvency.\n\nIn this talk I will show how we built 
 a personal storage system\, called Anzere\, where parts of the system use 
 the heterogeneous ensemble of a user's devices\, and parts are acquirable:
  the storage overlay has the option of acquiring one or more (virtual) res
 ources\, at some cost\, if the benefit in data invulnerability and accessi
 bility makes it worthwhile. Anzere makes personal data selectively availab
 le based on a set of user-specified replication policies. Compared to exis
 ting systems\, it extends the expressivity of the policy language to inclu
 de device-independence - referring to devices by predicate rather than nam
 e - yet still scales complex policy calculations up to very large numbers 
 of data items. Core elements of Anzere include an overlay network\, monito
 ring infrastructure\, constraint logic solver\, knowledge base\, data repl
 ication\, and Paxos. I will present initial results from trials of the sys
 tem across personal computers\, phones\, and dynamically-acquired virtual 
 machines from Amazon EC2 and PlanetLab.\n\nBio: Oriana Riva has been a sen
 ior researcher in the Systems Group at ETH Zurich since December 2007. She
  received her M.Sc. in Telecommunications Engineering from Politecnico di 
 Milano in 2003\, and her Ph.D. in Computer Science from the University of 
 Helsinki in 2007. Her research interests are in distributed systems\, with
  a focus on cloud computing infrastructures and mobile phone architectures
 . She was awarded an ETH Fellowship in 2008.\n
