The right to privacy, something a lot of people often forget, is not something explicity written into the Constitution. Nor is there a freestanding right to privacy law in the United Kingdom.
But that doesn't mean that millions weren't surprised to learn on Wednesday that, with help from the National Security Agency (NSA), the British surveillance agency Government Communications Headquarters (GCHQ) captured and stored the webcam images of millions of Yahoo users worldwide.
The surveillance program, code named Optic Nerve, was enacted in 2008 to collect still images from Yahoo webcam chats in bulk for the purpose of monitoring targets and testing facial recognition technology—regardless of whether or not the internet user was considered to be a security threat.
GCHQ documents, which were provided by NSA whistleblower Edward Snowden, show that somewhere between three and 11 percent of those images were sexually explicit and that the program was still active in 2012.
Yahoo has denied any prior knowledge of Optic Nerve and described it as being a "completely unacceptable" violation of privacy. Yet GCHQ said in a statement that what the agency did was not unlawful.
