DESCRIPTION:Prof. Kang Shin\,   University of Michigan \nAs use of locatio
 n-based services (LBSs) is becoming increasingly prevalent\, mobile users 
 are more and more enticed to reveal their location\, which may be exploite
 d by attackers to infer the points of interest (POIs) the users visit\, th
 en compromise their privacy. To protect a user's location privacy\, we hav
 e been developing a new approach based on unobservability\, preventing the
  attackers from associating any particular POI to the user's location. Spe
 cifically\, we designed\, implemented\, and evaluated a privacy-protection
  system\, called the Location Information ScrAmbler (LISA)\, that adjusts 
 the location noise level in order to remove or significantly weaken the di
 stinguishability of POIs the user may visit. By protecting location privac
 y locally on each mobile user's device\, LISA eliminates the reliance on t
 rusted third-party servers required by most previous approaches\, avoiding
  the vulnerability of a single point of failure and facilitating the deplo
 yment of LBSs. Moreover\, since energy-efficiency is the most critical req
 uirement for battery-powered mobile devices\, LISA explores the trade-off 
 between location noise/privacy and energy consumption to achieve both priv
 acy-protection and energy-efficiency. This is joint work with two of my gr
 aduate students\, Jerry Chen and Xin Hu. \nProf. Shin's homepage
