From http://appanalysis.org/privacyscope/: Demonstration. Paper is available at hxxp://www.eecs.berkeley.edu/Pubs/TechRpts/2009/EECS-2009-145.html. See the Discussions section for limitations. Privacy Scope needs to be compiled with Visual Studio. I didn't try Privacy Scope. The developers have created another program called TaintEraser that can prevent data loss, but apparently it hasn't been publicly released.
