Big Brother Watch has published a briefing note reviewing the issues with surveillance of communications data. Commenting on publication of briefing note Big Brother Watch said:
In the debate around state surveillance, we all too often we hear officials say that we have nothing to fear as only the communications data (or metadata) is examined, not the content of a communication. Big Brother Watch has therefore published a briefing not on why communications data matter.
In the briefing note you will find answers to questions like: what are communications data?; what can communications data reveal?; and how are communications data analysed?. We also include details of how communications data have evolved and whether the legal framework currently in place provides sufficient safeguards.
