The term metadata refers to “data about data” (e.g. card catalog at the library contains metadata – the Name of the Book, subject, where to find the book in the library, when it was written and information about its contents)
By Albert N. Milliron
So the Government is not just keeping a record of telephone numbers or email addresses, there is a lot more data that is being gathered and stored (like the library data card). We call that violations of privacy.
I can give you another example of what we do here in the office. We have something called a Software Defined Radio (SDR) that has the ability to record large chunks of the radio spectrum including satellite TV. If we get an indication that something is happening that we would like to review the radio traffic or a specific satellite Television station, we simply go to our hard drive time stamp and review the radio or TV traffic for that time frame.
Now, if nothing happens (like Breaking News) we simply allow that part of the hard drive be overwritten. We can literally go back in time and review police, fire, emergency traffic on our radios to get full information on a story we are working on.
Now we are not the Government, we have a small company here with limited resources. Still, we are able to record on a daily basis Radio and TV traffic and go back and get them if needed. The government has large facilities with billions of dollars of equipment and personnel. They also have large storage capacity.
Simply put, the government has access to much more information than they are letting you in on. That telephone call you made today is being placed on a hard drive with all of its indicating data, so if they want to they can listen to your phone call or read your email.
This is not science fiction, this is reality
Government can use Metadata to Map your every Move
WASHINGTON — If you tweet a picture from your living room using your smartphone, you’re sharing far more than your new hairdo or the color of the wallpaper. You’re potentially revealing the exact coordinates of your house to anyone on the Internet.
The GPS location information embedded in a digital photo is an example of so-called metadata, a once-obscure technical term that’s become one of Washington’s hottest new buzzwords.
The word first sprang from the lips of pundits and politicians earlier this month, after reports disclosed that the government has been secretly accessing the telephone metadata of Verizon customers, as well as online videos, emails, photos and other data collected by nine Internet companies. President Barack Obama hastened to reassure Americans that “nobody is listening to your phone calls,” while other government officials likened the collection of metadata to reading information on the outside of an envelope, which doesn’t require a warrant.
But privacy experts warn that to those who know how to mine it, metadata discloses much more about us and our daily lives than the content of our communications.
So what is metadata? Simply put, it’s data about data. An early example is the Dewey Decimal System card catalogs that libraries use to organize books by title, author, genre and other information. In the digital age, metadata is coded into our electronic transmissions.
