Progressive Pictorial & Motion Based CAPTCHAs

摘要

A CAPTCHA system uses images/pictures and/or motion for granting access to a computing system. The images can be culled from examples used in pictorial games, and can progressively presented to increase the strength of the CAPTCHA challenges. Speech recognition, motion and touch sensing can also be employed as parts of the challenge.

主权项

1. A method of testing recognition of images for a Completely Automatic Public Turing Test To Tell Humans And Computers Apart (CAPTCHA) system comprising:
a. automatically electing an electronic image for a participant with a computing system, wherein said electronic image comprises a set of imagery data other than words, and wherein said electronic image is configured such that a subset of said set of imagery data for said electronic image can be made perceptible in a first image state; b. associating said electronic image with one or more concepts; c. presenting said electronic image in said first image state and progressively revealing information over a first time period within an interface for said participant using said computing system; and d. automatically processing responses from the participant with the computing system to correlate an accuracy of guesses from said participant for said one or more concepts associated with said electronic image.
