Abstract
Validating that a user is a human may be accomplished through various techniques. In one embodiment, a first portion of a captcha is displayed at a first time. A second portion of the captcha image is displayed on the display at a second time, wherein the second time is subsequent to the first time. In another embodiment, an interactive task is presented on a display for a user to perform. Then a captcha image is displayed on the display once the user completes the interactive task. In either embodiment, a user may be accepted as human if input from the user matches predefined input corresponding to the captcha image.
