Online CAPTCHA Replacement through Face Detection

Abstract

The sensitive information stored on the internet should not be easily accessible by any unauthorized personnel, it should be readily available only to the authorized people. Thus integrity, security and confidentiality need to be maintained. There needs to be a security check before any kind of access is granted to any kind of sensitive information. CAPTCHA (Completely Automated Public Turing Test to tell Computers and Humans Apart) is a popular way for authenticating a user. The main goal of any technique is to recognize whether it is a human who is accessing the content or a robot via some recognition techniques. The advancement in recognition technologies has enabled humans to develop bots which can now bypass common authentication techniques which have been in use for a long time. CAPTCHA has been in use since a very long time and has some serious drawbacks. Facial recognition alongside with artificial intelligence can overcome drawbacks like difficulty in solving, ambiguity, and sometimes easy prey for trained bots of CAPTCHA and can easily replace it.
