Amongst the thousands of documents extracted from the NSA by its ex-employee there is a graph which describes the extent of telephone monitoring and tapping (DNR – Dial Number Recognition) carried out in France. It can be seen that over a period of thirty days – from 10 December 2012 to 8 January 2013, 70,3 million recordings of French citizens’ telephone data were made by the NSA. This agency has several methods of data collection. According to the elements obtained by Le Monde, when a telephone number is used in France, it activates a signal which automatically triggers the recording of the call. Apparently this surveillance system also picks up SMS messages and their content using key words. Finally, the NSA apparently stores the history of the connections of each target – or the meta-data.
