CAPTCHA stands for Computer Automated Public Turing test to tell Computers and Humans Apart which is a widely used security technique to avoid spams and automatic form submissions by bots, thus ensuring that the end user is a human. An alternative to the present text based CAPTCHA which is based on hand gesture recognition and pattern matching is proposed in this paper. This approach will verify user as human and prevent bots from spamming applications and services thus making the entire process more secure and reliable.
