If you’re concerned about meddling bots reading your Twitter activity, try CAPTCHA Tweet, a simple app that translates ordinary text into an image that’s readable to humans but not computers. You may recognize CAPTCHA as the test sites like Ticketmaster use to make sure you’re a human before you access their services: letters are distorted enough that computer programs can’t recognize them, but not so much that they’re unreadable to us real people.
CAPTCHA Tweet‘s creators, the South Korean art collective, Shinseungback Kimyonghun, explain their intentions on their website.
We see CAPTCHA as a symbol of the relationship between human vision and computer vision and the intervention of computers in human life. CAPTCHA Tweet attempts to re-present this implication of CAPTCHA to the public sphere by applying it to the social network communication.
