In an attempt to do human detection for a support web page, I've come up with a scheme I think might be viable, and I wanted to run it past you guys.

The idea is to present a table with a randomly selected number of columns (from three to five), with two rows. the first row contains images, and the second row contains Submit buttons.

The images that can be presented (at least 20, probably more) are contains in a folder with descriptive names, such as "green square", "dog", or "car". When a user goes to the page, the files are randomly selected, and for each file, a file name based on a quid is created, and the original file is copied to a temp folder with the guid file name. One of the selected files is randomly selected as the "correct" image, and the user is prompted to click the appropriate button (based on its original file name, like this:

"Click the submit button under the picture of XXXXX"

where "XXXXX" is the name of the original file (minus the extension, of course). So, if one of the displayed files was "dog 01.jpg", a guid file name would be generated like this - "00000000-0000-0000-00000000.jpg" - and the control's ImageUrl is set to this guid file name, and the prompt would read "Click the Submit button under the picture of the dog."

This mechanism is intended to prevent bots from learning the system by looking at the image name, or expecting a fixed number of choices, and still allows a number of "dog" images to be used so that the image isn't the same every time the page is presented. Post-backs would delete the temporary images.

What do you guys think? Will it be effective?
