A Study of Audio Captcha and their Limitations

Due to the massive development of Internet, security of web application has turned into a fundamental issue and numerous web applications confronting a danger of Internet Bots otherwise called Internet Robot is the automated program which executes over the web application and spoils valuable web space. CAPTCHA has become accepted standard for securing web applications from Internet Bots and all the application/ forms utilize this test for verification purposes. This paper is an aggregate study of work done on Audio CAPTCHA frameworks. In the accompanying segment, talked about the limitation of different audio captcha approaches and followed by evaluation of the usability and accessibility of audio CAPTCHA.
