Abstract
Methods and systems for verifying whether a submission of a request is likely from a human user or an automated program are described. A request may be received from a user device. A human challenge-response test adapted for displaying on the user device is displayed on the user device. Upon viewing the human challenge-response test, the user enters the user's solution to the human challenge-response test on the user device. A response hash value is created based on the user's solution. The response hash value is sent to a computing device for verification.
