Summary: | Provided is a Captcha Access Control System (CACS) for generating an improved captcha that are based, in one described embodiment, upon a command in one format and a response in a different format, one or both of which are rendered in a format that is difficult for an automated system to interpret. A computer system or program to which a user is requesting access generates a textual or audible command. A video device captures the user's response and transmits the response to a response evaluation device. Based upon an analysis of the transmitted video and a comparison between the analyzed video and the command, the computer or program either enables access or denies access. |
