Abstract
Particular embodiments determine a modified image for a CAPTCHA. The CAPTCHA may include an original image, a challenge based on the original image, and/or a correct response based on the original image. The modified image may be a scrambled version of the original image. Web-browser-executable code is determined for unscrambling the modified image back to the original image. The modified image and the web-browser-executable code are then provided to a computing device. Upon receiving the modified image and the web-browser-executable code, the computing device then displays the original image based on the modified image and the web-browser-executable code.
