Published research on automated user monitoring (Score 1)

This thread seems like old news: my old firm did R&D for government agencies on using artificial intelligence to track most of the interactions occuring on a computer by a user. Using statistical and natural language understanding methods, you can estimate things such as "the user is sending social security numbers as email attachments". The research led to several prototypes, and the prototype for examining users emails, messenger sessions, socket traffic, etc. should be publically available with the finished contract.
