Providing increasing numeric order might make bot guess wrong answer 90% of time,which is quite comparable to the current captcha system that uses OCR as provided in the given algorithm: http://www.gizmag.com/captcha-beating-ai/29559/ . 2)Ask User to click on the same image as provided:The question for this type of captcha looks like this:https://commons.wikimedia.org/wiki/File:Proposal5correction.png we can ask user to click on the options showing equivalent image to that provided in the question.For the question provided the answer is :https://commons.wikimedia.org/wiki/File:Proposal9correction.png .Ps:we ca use more than four options probably eight options since it would be harder of bot to make a guess. 3)For blind and visually impaired users:We can use and audio captcha system which ask user to select the number as it is asked in the audio .For example the visual equivalent of the audio asked by the user will be : https://commons.wikimedia.org/wiki/File:Proposal11correction.png .Now when audio asked user to select number "0" our user will use arrow key to move across different blocks like a slide show....with different voice speaking out the options and pressing enter will select the word spoken....hence verifying that the user is human.....although the above shown image is visual equivalent the actual image visible will be: https://commons.wikimedia.org/wiki/File%3AProposal4correction.png ;....to make the captcha reload we can user to by pressing key "r" which will be instructed in the audio while the captcha starts playing.
