Abstract
Techniques are described herein for providing a marketplace for CAPTCHA developers. A CAPTCHA is a type of challenge-response test that a content provider may present to users for authorizing the users to access content that is hosted by the content provider. CAPTCHA developers may propose CAPTCHAs for testing in the marketplace. A server is configured to provide instances of proposed CAPTCHAs to users along with instances of reference CAPTCHAs that have known difficulties to determine the relative difficulties of the proposed CAPTCHAs for the users. The server may determine a reward to be provided to a developer of a proposed CAPTCHA based on a difficulty that the predetermined automated systems encounter when they attempt to solve the proposed CAPTCHA and an ease with which the users solve the proposed CAPTCHA. The server may determine rewards to be provided to developers of predetermined automated systems that solve the proposed CAPTCHAs.
