Breaking of Captcha to Measure Its Strength

چکیده
In this paper, we have proposed a system to grade CAPTCHA strength, according to various parameters determined by breaking the CAPTCHA. There are basically four major steps involved in the system.First step is preprocessing which includes – binarization and noise removal.Second step is segmenting the image into individual characters. Third step is to obtain skeletons of characters i.e., Thinning. The final step is character recognition. For character recognition we have used artificial neural networks.
