Abstract

There is a need for a CAPTCHA as a result of the abuse of automated 'bots' [6]. The problem of spamming resulted as the bots intruded into the internet [3]. However, there were many solutions provided for stopping these bots from entering the internet. The best and most feasible solution proposed till now has been the CAPTCHA or the fuzzy text recognition. But the latest news that hurt the organisations that use CAPTCHA is that the bots started recognizing these fuzzy texts. In this paper we propose a novel yet simple idea which can serve as a replacement to CAPTCHA. There have been several image based CAPTCHA's proposed and as well defeated [1]. But our Idea THINK is in the same lines yet is fool proof. In this paper we suggest that a real time image is used which will portray some action or show some object that the user is expected to identify the object and type the answer. No choices will be given to the user thereby eliminating the option of identifying the answer by probability.
