Using Automated Public Turing Test Avoiding Password Guessing

S. Vaishnavi, Anjana Devi .J and N. Sankar Ram


CAPTCHA will demonstrate information about word tests for easy human recognition. CAPTCHAs used to differentiate human and non ? human or bots. Gibbs re-sampling repeatedly generate random word until the word becomes human-readable. Passwords are usually used for authentication purpose. Two types of attacks are Brute Force attack and Dictionary Attack which can be avoided using CAPTCHA. Bots using Optical Character Recognition (OCR) program for tracing CAPTCHAs.The main aim of this paper is to avoid online password guessing, here we proposed a new Password Guessing Resistant Protocol (PGRP), derived upon revisiting prior proposals designed to restrict such attacks and replace the word captacha.

Keywords: Password Guessing Resistant Protocol (PGRP), GIBBS Sampling, Scatter Type Algorithm, Color Filling Segmentation (CFS) Algorithm, Optical Character Recognition (OCR).
