The recent Stanford University study that showed the difficulties caused by text based captcha to human beings who aim to decipher it, had expectedly pushed forward image based captcha developers.
Thus, Confident Technologies has released its image based captcha plugin for Wordpress, stating that product is “easy on people while being tough on bots” as opposed to the frustrating, site abandoning encourager text based captcha. Confident Captcha displays a number of images, organized in a grid, asking the user to prove his humanness by clicking on one of the presented images. Users can choose the number of images and the background color to avoid the common side effect of image based captcha, its being the center of attention.
Just released on June 23, the Confidential Captcha was downloaded only by two dozens of users (as for the moment of writing); Still, looking at some of the most popular text-based captcha plugins for Wordpress, you hardly notice a meaningful drop in the number of downloads a day, nor a huge increase in the number of image-based captcha downloads. So,difficult or not, most Wordpress users may be still hung on the good old “type the two words” captcha.
