The FBI has retired Carnivore, a controversial Internet surveillance tool. This is a different from Echelon. Echelon is a monitoring platform operated by the NSA. Echelon apparently captures significant volumes of data worldwide. This report is very interesting and it brings to mind George Orwell’s 1984.
Good thing we have governments so focused on privacy otherwise this type of technology might be needed if things start to get out of hand. These folks, however, seem to be less impressed with the privacy efforts.
