Lauscher an der Wand
With half a century’s experience of listening to feeble radio signals from space, NASA is helping US security services squeeze super-weak bugging data from Earth-bound buildings.
It is easy to defeat ordinary audio eavesdropping, just by sound-proofing a room. And simply drawing the curtains can defeat newer systems, which shine a laser beam onto a glass window and decode any modulation of the reflected beam caused by sound vibrations in the room.
So the new “through-the-wall audio surveillance system” uses a powerful beam of very high frequency radio waves instead of light. Radio can penetrate walls – if they didn’t, portable radios wouldn’t work inside a house.
The system uses a horn antenna to radiate a beam of microwave energy –between 30 and 100 gigahertz – through a building wall. If people are speaking inside the room, any flimsy surface, such as clothing, will be vibrating. This modulates the radio beam reflected from the surface.
Although the radio reflection that passes back through the wall is extremely faint, the kind of electronic extraction and signal cleaning tricks used by NASA to decode signals in space can be used to extract speech.

UK Identity Project
Niels J Bjergstrom über das britische IdentityCard Projekt.
The whole approach to this project is reactive rather than forward-looking and proactive. The justifications for introducing a national identity system in the Bill include ‘the interest of national security’, ‘the enforcement of prohibitions on unauthorised working’, ‘enforcement of immigration controls’ and ‘prevention and detection of crime’.
These goals seem to be missing: ‘enabling and facilitating a society based on e-commerce’, ‘increasing individual freedom by enhancing anonymity and privacy’, ‘enabling irrefutable authentication of humans to machines’ and ‘providing individuals with transactional security’. These are some of the positive drivers of an eID system, some of the drivers that will actually be able to underpin the acceptance by the public and justify the huge expenses initially associated with establishing and not least running an eID system.
FBI
Die Washington Post berichtet über versteckte Überwachungen gegen US Bürger durch das FBI.
Zum Teil wurde “vergessen” das Justizministerium zu informieren, Lauschmaßnahmen liefen nach Ablauf der genehmigten Frist weiter, …
Warum überrascht mich das bloß nicht?!
(…) in a letter to be sent today to the Senate Judiciary Committee, Sobel and other EPIC officials argue that the documents show how little Congress and the public know about the use of clandestine surveillance by the FBI and other agencies.
