CAPTCHA or Asirra (Dog-Cat)?
Sunday, March 16, 2008 1:25
Microsoft Research Center started a very promising project, about a year ago. The project name is Asirra (Animal Species Image Recognition for Restricting Access), and it is a HIP (Human Interactive Proof), a way to prove that you are a human and not a bot, something like CAPTCHA)
As we can read in the project’s page
Today, the most common HIPs ask users to identify text that has been distorted or obscured, like the example seen to the right. Unfortunately, such challenges can be difficult and frustrating for people, yet are often easily solved by computers
What microsoft suggests (in cooperation with Petfinder) is to display several pictures of pets from the petfinder’s database (3,000,000 photos). The user has to indicate whether a pet is a dog or a cat. If he selects the right combination he proves that he is a human.
