Of course with best intentions, researchers at the Air Force Institute of Technology at Wright Patterson Air Force Base are developing a system for detecting insider threats within organizations. This is done by data mining operations on the organization's emails, thus revealing social networks within that organization. Even individuals "who feel alienated within the organization" can be spotted by analyzing certain changes in their social behaviour, tracked by that software.

I've read about many paranoia systems but this outweighs others by far. If an individual "feels alienated", she has reasons for this. So going to the workers' council becomes a subversive act again! If people learn that they are monitored, they will change their behaviour, anyway. And if somebody really wants to get information that wasn't intended for him, or if he wants to destroy something, he won't wait for that until you're ready with analyzing his profile.

Dear researchers: Is your hubris that big that you don't even consider abuse of your system and its data? There are still enough people in Germany who have a lot of experience with a totalitarian state (the former GDR), a governmental system based on nosing the own people and draconian penalties for subversive elements. Go out, ask them and take some history lessions about dictatorship and Big Brother scenarios! (Source)
