detect bot using images - asp.net
I tried to search this on the net but was not able to find a solution. Probably I am not entering the correct search keywords.
I currently have a bot detect mechanism in place for my page but it needs the user to type in an alpha-numeric value given in the image.
This is pretty standard. The below image is what I am currently using.
The problem is it is having its own issues.
Plus there are a host of customers out there who do not want to use their keyboard or have problems with reading these images.
I want a botdetect mechanism which does not involve keyboard.
For example, a 3 X 3 grid of images and asking a user to tick all those images which contain, maybe, "icecream".
It would be better if somebody can suggest a third party tool which I can just consume.
Please help! Thanks in advance!
P.S.: Please pardon me in case I have added a wrong tag
They are called captcha
The one you are referring to as using images and not requiring a keyboard is most likely googles HERE.
