Echelon is the name of the system that made me being interested in the current status of surveillance. I got to know something about it because of media coverage after the report to the European Parliament, which I already mentioned, was published ([28]). Although I will try to describe this system as accurately as possible, I have to repeat that most information I found is based mainly on two sources: that report and a book by an journalist from New Zealand ([21]). This journalist also wrote a summary of his book, which can be found at [20].
