[Captcha](https://en.wikipedia.org/wiki/CAPTCHA) is a system used on popular websites to stop bots or automatic software to access the site. [IRCTC](https://www.irctc.co.in/eticketing/loginHome.jsf) is a popular travel website in india where people book travel tickets on trains. Because of high demand of tickets, booking during peak hours (tatkal) has a captcha image containing letters that humans have to enter to book the ticket. This supposedly stops ticket booking through automated software.

Using the residual networks (34 layers deep) which won the Imagenet challenge and some data augmentation improves the captcha accuracy to 98%. I have added the relevant code. Run mainr.lua or mainaug.lua.

## What it means
Captcha as a system is vulnerable and should be stopped as noted [here](http://www.geek.com/news/ai-beats-captcha-with-90-success-but-google-has-something-new-1575339/). There are other means to stop automated software. This is a demonstration that the current captcha system used by IRCTC is vulnerable and doesnt do its intended purpose of stopping automated booking. Thats one reason why a lot of automated software is puportedly [available](http://timesofindia.indiatimes.com/tech/tech-news/IRCTC-website-is-sitting-duck-to-hackware/articleshow/50412277.cms). I have tried contacting IRCTC to let them know about this. Atleast this will make them stop using captchas which doesnt stop bots and even inconvenice legit users.
