DESCRIPTION:Detecting and Explaining Privacy Risks on Temporal Data\n\nSpea
 ker: Marie-Christine Rousset\, Professor at University of Grenoble\n\nAbst
 ract:\n\nPersonal data are increasingly disseminated over the Web through 
 mobile devices and smart environments\, \nand are exploited for developing
  more and more sophisticated services and applications. All these advances
  \ncome with serious risks for privacy breaches that may reveal private in
 formation wanted to remain undisclosed \nby data producers. It is therefor
 e of utmost importance to help them to identify privacy risks raised by re
 quests \nof service providers for utility purposes.\n\nIn this talk\, I wi
 ll focus on the temporal aspect for privacy protection since many applicat
 ions handle dynamic data \n(e.g.\, electrical consumption\, time series\, 
 mobility data) for which temporal data are considered as sensitive and \na
 ggregates on time are important for data analytics. I will present a forma
 l approach for detecting incompatibility \nbetween privacy and utility que
 ries expressed as temporal aggregate conjunctive queries. The distinguishi
 ng point \nof our approach is to be data-independent and to come with an e
 xplanation based on the query expressions only. \nThis explanation is inte
 nded to help data producers understand the detected privacy breaches and g
 uide their choice \nof the appropriate technique to correct it.
