Advances in the field of Information Technology (IT) make Information Security an inseparable part of it. In order to deal with security, authentication plays an important role. Computer Scientists have developed Human Interactive Proof (HIP) commonly known as CAPTCHAs (Completely Automated Turing Tests to Tell Computers and Humans Apart) as a challenge-response test used in computing to determine and confirm the identity of an individual requesting their services form that of malicious automated scripts. It is a security measure which uses computer programs that automatically generate and grade puzzles that most people can solve without difficulty, but that current programs cannot. The purpose of such schemes is to ensure that the rendered services are accessed only by a legitimate user, and not anyone else. This paper presents a brief overview of the literature in the field of CAPTCHA authentication techniques in the online environment. Furthermore, it evaluates HIP with an objective to provide insights on their lack of acceptance as well as some suggestions for further research in this field.
