DESCRIPTION:Privacy preservation has become a major demand for databases c
 ontaining personal information. While the issues relative to privacy discl
 osure are well identified and investigated\, the description of a global f
 ramework that reposition privacy preservation/utility trade-off in informa
 tion theoretical ground is still missing. In this talk I will present some
  existing results showing in particular that differential privacy is not a
 bly to guarantee optimal privacy/utility tradeoff. I will thereafter re-ex
 press privacy preservation problem in the context of rate/distorsion funct
 ions and show that a formulation similar to lossy compression can guarante
 e optimal privacy/utility trade-off. I will thereafter describe some encod
 ing scheme achieving this solution and illustrate it on several cases.\n\n
 Bio: Kavé Salamatian is a full professor at University of Savoie. His mai
 n areas of researches are Internet measurement and modeling\, and networki
 ng information theory. He was previously reader at Lancaster University\, 
 UK and associate professor at University Pierre et Marie Curie. Kavé has 
 graduated in 1998 from Paris SUD-Orsay university where he worked on joint
  source channel coding applied to multimedia transmission over Internet fo
 r his Phd. In a former life\, he graduated with a MBA\, and worked on mark
 et floor as a risk analyst and enjoyed being an urban traffic modeler for 
 some years. He is working these day on figuring out if networking is a sci
 ence or just a hobby and if it is a science what are its fundamentals.\n
