-  * Web log data . . . Google analytics,  +  Satellite images: This includes weather data or the data that the government captures in its satellite surveillance imageryJust think about Google Earthand you get the picture (pun intended).  
-  * Point-of-sale data . . . Cashiers' swipes . . . .  +  * Scientific data: This includes seismic imagery, atmospheric data, and high energy physics.  
-  * Financial data+  * Photographs and video: This includes security, surveillance, and traffic video.  
 +  * Radar or sonar data: This includes vehicular, meteorological, and oceanographic seismic profiles.
