If a stranger came up to you on the street, would you give him your picture? Probably not.Yet people often dole out all kinds of personal information on the Internet. Services like Facebook, Google Plus, Twitter and Flickr are oceans of personal minutiae — birthday greetings sent and received, school and work gossip, photos of family vacations, and movies watched.Computer scientists and policy experts say that such seemingly innocuous bits of self-revelation can increasingly be collected and reassembled by computers to help create a picture of a person’s identity, sometimes down to the Social Security number. I am trying to potray this through ‘Privacy Pixels’. Using a server side script, profile pictures of random people from facebook are fetched. These pictures are then used in constructing the ‘Privacy Pixels’. The pixel blocks with silhouette are the people who did not upload a profile picture.
Note: Facebook allows anyone (may not be your facebook friend) to fetch your profile picture in four different sizes. There is no privacy settings to disable this.
This video shows the dynamic construction of the Privacy Pixel Canvas. Tens and Thousands of Profile Pictures were fetched to complete this canvas. Music composed in Fruity Loops.
