Intelligence services collect metadata on the communication of all citizens. Politicians would have us believe that this data doesn’t say all that much. A reader of De Correspondent put this to the test and demonstrated otherwise: metadata reveals a lot more about your life than you think.
Ton Siedsma is nervous. He made the decision weeks ago, but
keeps postponing it. It’s the 11th of November, a cold autumn evening.
At ten past eight (20:10:48 to be exact), while passing Elst station on
the way home, he activates the app. It will track all of his phone’s
metadata over the coming week.
Metadata is not the actual content of the communication, but the data
about the communication; like the numbers he calls or whatsapps, and
where his phone is at a particular moment. Whom he e-mails, the subject
of the e-mails and the websites he visits.
Ton won’t be doing anything out of the ordinary. He’ll just lead his
normal life. On weekdays, this means biking from his house in Nijmegen
to the station and taking the train to Amsterdam. On Saturday, he’ll
drive his car to Den Bosch and spend the night near Zuiderpark,
returning to Nijmegen the next day by public transportation. Later on in
the day he’ll have some drinks at a café called St. Anna.
After exactly a week, on Monday, 18 November, he concludes the
experiment, saying afterwards that he felt liberated when doing so.
There’s an easy explanation for his nervousness: what he’ll be doing,
where he’ll be and who he has contact with will be seen by tens of
thousands of people. Today, by you and me, and all the other readers of
this article.
Over the past months,>>>
