Abstract:

Systems and processes for performing user verification using an imaged-based CAPTCHA are disclosed. The verification process can include receiving a request from a user to access restricted content. In response to the request, a plurality of images may be presented to the user. A challenge question or command that identifies one or more of the displayed plurality of images may also be presented to a user. A selection of one or more of the plurality images may then be received from the user. The user's selection may be reviewed to determine the accuracy of the selection with respect to the challenge question or command. If the user correctly identifies a threshold number of images, then the user may be authenticated and allowed to access the restricted content. However, if the user does not correctly identify the threshold number of images, then the user may be denied access the restricted content.
