Abstract
In one embodiment, a client computing device receives information regarding a Completely Automated Public Turing Test to Tell Computers and Humans Apart (CAPTCHA). The CAPTCHA includes an image file, a challenge, and code that is executable by a web browser to unscramble the received image file. The code includes instructions to divide the received image file into image sections, each image section having a unique identifier and grouped into either a first set or a second set. The code further contains instructions to transpose each image section in the first set into a new position, creating a new image. A web browser of the client computing device executes the code to create a second image from the received image file. The second image and the challenge are presented to a user of the client computing device.
