Survey on Captcha Recognition Using Deep Learning

With the increasing dependency of people and evolving technology, security has become an issue on online platforms. Earlier days CAPTCHA was introduced to provide protection and security in web but lately due to the new bulk of web bots, now security becomes a major concern as it could be easily breached. This paper discusses about the technique involved that can help in optimizing the performance of a captcha breaking model and also provide a moot that can help to withstand the guard of captchas.
