Privacy Games

DP VISION

The images in this game are obscured using differential privacy, and your challenge is to identify which of the three images matches the original within 5 guesses.

How to Play

  1. Privacy budget starts at 100%
  2. Adjust the epsilon
    Control how much detail is revealed by adjusting the epsilon. The higher the epsilon value, the clearer the image—but the cost is privacy.
  3. Choose an image
    Compare the blurred image to the three options and select the one that you think matches the original.
  4. Image resets with each guess
    Each time you guess, a new blurred image is presented. So you can’t win by eliminating the options with 2 random guesses.
Your total epsilon spent before you get the right answer will place you on the leaderboard. Lower the epsilon, higher you rank!
