In the latest revelation from documents gathered by former National Security Agency contractor Edward Snowden, the Guardian reports that Yahoo chat users’ webcam images have been intercepted and stored by the British surveillance agency GCHQ:
Britain’s surveillance agency GCHQ, with aid from the US National Security Agency, intercepted and stored the webcam images of millions of internet users not suspected of wrongdoing, secret documents reveal.
GCHQ files dating between 2008 and 2010 explicitly state that a surveillance program codenamed Optic Nerve collected still images of Yahoo webcam chats in bulk and saved them to agency databases, regardless of whether individual users were an intelligence target or not. […]
Yahoo reacted furiously to the webcam interception when approached by the Guardian. The company denied any prior knowledge of the program, accusing the agencies of “a whole new level of violation of our users’ privacy”.
GCHQ does not have the technical means to make sure no images of UK or US citizens are collected and stored by the system, and there are no restrictions under UK law to prevent Americans’ images being accessed by British analysts without an individual warrant.
The documents also chronicle GCHQ’s sustained struggle to keep the large store of sexually explicit imagery collected by Optic Nerve away from the eyes of its staff, though there is little discussion about the privacy implications of storing this material in the first place.
Optic Nerve, the documents provided by NSA whistleblower Edward Snowden show, began as a prototype in 2008 and was still active in 2012, according to an internal GCHQ wiki page accessed that year. […]
Bulk surveillance on Yahoo users was begun, the documents said, because “Yahoo webcam is known to be used by GCHQ targets”. […]
The privacy risks of mass collection from video sources have long been known to the NSA and GCHQ, as a research document from the mid-2000s noted: “One of the greatest hindrances to exploiting video data is the fact that the vast majority of videos received have no intelligence value whatsoever, such as pornography, commercials, movie clips and family home movies.”
