There is a lot of activity over the internet. Be it, posting a comment on someone‟s blog or making a Gmail account or booking a ticket online. But with that also comes the problem of spamming. “Completely Automated Public Turing test to tell Computers and Humans Apart” (CAPTCHA) [8] which are the twisted words that block the entries of bots on website. CAPTHCAs can effectively test if the user is human or machine. Hence it is of great importance that CAPTCHA is well checked for its…

Captcha Recognition and Robustness Measurement using Hybrid Approaches

This paper carries out a systematic study of various Text-based Captchas and proposes the application of Forepart based prediction and Rowwise mapping to break these captchas to evaluate their robustness.

The End is Nigh: Generic Solving of Text-based CAPTCHAs

The effectiveness and universality of the results suggests that combining segmentation and recognition is the next evolution of catpcha solving, and that it supersedes the sequential approach used in earlier works.

Attacking Image Recognition Captchas - A Naive but Effective Approach

An successful approach to attack this type of Captcha is developed, which delivers promising results for the HumanAuth Captcha and others, and several techniques for improving future versions of image recognition CAPTCHAS are proposed.
