SUMMARY:Wednesdays@NICO Presents: From Human Behavior to the Spread of Mobile Viruses
DESCRIPTION:Presenter: Pu Wang - University of Notre Dame Lacking a standardized operating system\, traditional cellphones have been  relatively immune to viruses. Smartphones\, however\, can share programs and data  with each other\, representing a fertile ground for virus writers. Indeed\, since  2004 more than 420 smartphone viruses have been identified. Given smartphones’  high annual growth rate\, they are poised to become the dominant communication  device in the near future\, raising the possibility of virus breakouts that could  overshadow the disruption caused by traditional computer viruses. To understand  the spreading patterns of mobile phone viruses\, we must know human’s collective  and individual behaviors\, such as human’s communication pattern and mobility  pattern\, which provide the spreading channels for the MMS and Bleutooth viruses.  Based on the statistical analysis of human behaviors\, we model the mobility of  mobile phone users to study the fundamental spreading patterns characterizing a  mobile virus outbreak. We find that while Bluetooth viruses can reach all  susceptible handsets with time\, they spread slowly due to human mobility\,  offering ample opportunities to deploy antiviral software. In contrast\, viruses  utilizing multimedia messaging services could infect all users in hours\, but  currently a phase transition on the underlying call graph limits them to only a  small fraction of the susceptible users. These results explain the lack of a  major mobile virus breakout so far and predict that once a mobile operating  system’s market share reaches the phase transition point\, viruses will pose a  serious threat to mobile communications. NICO Coffee Hour will follow for questions\, networking\, and collaboration.     http://www.northwestern.edu/nico/events/index.html#seminars
