Captcha as Graphical Passwords—A New Security Primitive Base

Many security primitives are based on hard mathematical problems. Using hard AI problems for security is emerging as an exciting new paradigm, but has been under explored . In this paper, we present a new security primitive based on hard AI problems, namely, a novel family of graphical password systems built on top of Captcha technology, which we call Captcha as graphical passwords (CaRP). CaRP is both a Captcha and a graphical password scheme. http://kaashivinfotech.com/ http://inplanttrainingchennai.com/ http://inplanttraining-in-chennai.com/ http://internshipinchennai.in/ http://inplant-training.org/ http://kernelmind.com/ http://inplanttraining-in-chennai.com/ http://inplanttrainingchennai.com/

  3. Abstract • Many security primitives are based on hard mathematical problems. Using hard AI problems for security is emerging as an exciting new paradigm, but has been under explored . • In this paper, we present a new security primitive based on hard AI problems, namely, a novel family of graphical password systems built on top of Captcha technology, which we call Captcha as graphical passwords (CaRP). CaRP is both a Captcha and a graphical password scheme. • CaRP addresses a number of security problems altogether, such as online guessing attacks, relay attacks, and, if combined with dual-view technologies, shoulder-surfing attacks. Notably, a CaRP password can be found only probabilistically by automatic online guessing attacks even if the password is in the search set.

  4. Existing System • In the existing system, a captcha and picture based authentication is designed to authenticate into the system. • The concept of visual cryptography has been integrated with the captcha for individual user and got splitted equally in order to store in the server. • The Server provide authentication to the requestor thereby verifying the captcha by merging the splitted shares to ensures the authorized human interpretations. • The authentication by means of picture also been the part of the existing methodology that has a feature of picture spot clicking password. • The drawback of the existing system is that only a specific number of pictures can been utlized to set as a password and there is no successive cued clicks. Hence the vulnerability of cracking the password is high that leads to insecurity

  5. Proposed System • The concept of captcha to interpret the authorized human is incorporated that prevail the human inference with the server by cryptographic concepts. • Image hotspot technique accompanying with the notion of captcha designs the system in enhanced way with security measure. • A successive image hotspots has been designed by means of graphical representation or clued points on the image taken. • On the thriving traversal of the 5 successive hotspot images ,the user get authenticated to the server.

  6. System Requirements • Hardware Requirements: Platform : DOTNET (VS2010) , ASP.NET Dot net framework 4.0 Database : SQL Server 2008 R2 • Software Requirements: Processor : Core 2 duo Speed : 2.2GHZ RAM : 2GB Hard Disk : 160GB
