Secure user authentication using captcha as passwords based on graphical methods

Abstract

An alternative to traditional text-based password is being proposed. This aims to enhance the safety and security of the current system by adding a layer of additional security, the proposed system uses FIDO (Fast Identity Online) which unlike password catalogue, stores personally recognizing information data locally on the handler's device to defend it. FIDO's personal identification and local storing of biometric is an intended way to ease user apprehensions about personal data. Image-captchas have lately developed into a very prevalent and extensively organized crossways throughout the online networks to guard from the offensive things. Still, the developing competence in the system field has steadily weakened the safety of Image-captcha and has exposed them to attacks. Built on our valuation, we roughly recognize the defects in these methods of prominent structures, laterally with the perfect performance and plan. Ideologies for more secure captchas are formed from our findings which lean-to light on the considerate of measure and impact, for captcha solving.
