Our Metadata, Ourselves
True, we have always known that the outside of any envelope we place in the mail can be seen. We have always known that the phone company had access to “pen register” information, and that the bits and bytes that make up our e-mails are “known” to the various providers transmitting them. But we also did expect that the keepers of the media would take no interest in our metadata, would in fact be bound by rules of confidentiality, and that they would not only safeguard the contents of the communications, but also, to the extent practical, the fact of the communications too. We certainly didn’t think that the metadata would be analyzed by a government agency.
