PRISM

[gvidas]

To put it in context, all of these little bits of secondary information add up to an amazing picture of everyone. Bruce Schneier's summary is "metadata is surveillance," which I quite like:

Imagine you hired a detective to eavesdrop on someone. He might plant a bug in their office. He might tap their phone. He might open their mail. The result would be the details of that person's communications. That's the "data."

Now imagine you hired that same detective to surveil that person. The result would be details of what he did: where he went, who he talked to, what he looked at, what he purchased -- how he spent his day. That's all metadata.

When the government collects metadata on people, the government puts them under surveillance. When the government collects metadata on the entire country, they put everyone under surveillance. When Google does it, they do the same thing. Metadata equals surveillance; it's that simple.
