This is Your Metadata


So important I posted it twice:
  • Europeans' data shared 376 times daily in advertising sales.
  • The figure rises to 747 times daily for US-based users.
  • The revenue from digital adverts is what keeps most internet services free to use.
  • (Not for long, says Tim Hwang, Subprime Attention Crisis, 2020)

The Data:
  • Device the page is loading on
  • Location details
  • Previous websites visited and their subject matter
  • This data is used to secure the most relevant bidder for the advert space on the page
  • This all happens automatically, in a fraction of a second, and is a multi-million dollar industry
  • Personally-identifying information is not included, but campaigners argue that the volume of the data is still a violation of privacy 
  • Figures do NOT include numbers from Facebook and Amazon, only Google
  • US web users' habits are shared in advert sales processes 107 trillion times per year
  • European users' data is shared 71 billion times per year

***
People forget, but in 2006 AOL released search data, but took it back down the same day when they realized that you could very easily re-identify the people in the data. There was a competition to prove this, done on both Netflix and Twitter users.

The internet doesn't forget.
