A Novel Method for Graphical Password Mechanism

For the verification of authorized users in computer systems, various text based or biometrics methods are used. But these methods have some drawbacks. It is difficult to remember and recall the textual i.e. alphanumeric passwords. To avoid this drawback users prefer to create effortless, short, easy and insecure passwords which are easily guessable by hacker and this makes the system more vulnerable to attacks. On other hand, verification mechanisms based on biometrics offers security to a good extents. But they are quite luxurious for implementation. Cost becomes a key factor in the case of biometrics. Also any injury to the body part used in biometric authorization results in denial of access or performance issues. Graphical password provides another way by providing passwords that are more protected and unforgettable in a reasonable price. In this system, user clicks on images instead of typing passwords for accessing the system. This paper describes and examines usability and security of graphical password mechanism for authentication using graphical passwords. Proposed system describes characteristics for security and performed empirical study comparing Graphical password mechanism with Biometric passwords and alphanumeric password.

Graphical Password Scheme Using Cued Click Point and Persuasion with Multiple Images

There are three main categories of authentication system – token-based (what you have), biometric-based (who you are) and knowledge-based (what you know). Cued Click Point is a graphical password scheme which is a type of knowledge based authentication. In CCP, user clicks on one point per picture for an arrangement of pictures.CCP gives more prominent security than PassPoints in light of the fact that the quantity of pictures builds the workload for attackers. The proposed system uses persuasion allowing user’s choice to a certain extent while encouraging users towards stronger and less-vulnerable passwords.In the proposed system, the undertaking of choosing less secure passwords (which are simple for attackers to hack) is more monotonous, disheartening users from settling on such decisions.In actuality, this approach makes picking a more secure secret key less weight on clients, it is less demanding to take after the framework's recommendations for a protected password—an element lacking in many systems. CCP is an effective alternative to text-based passwords and other forms of traditional authentication system. Psychological studies have also revealed that human mind can recognize images faster than text and numbers. CCP can be applied to a system front-end which requires high level of security.This paper presents implementation of Cued Click Point (CCP) graphical password which uses persuasion along with multiple images

Securing Web Accounts Using Graphical Password Authentication through MD5 Algorithm

Today, most Internet applications still uses traditional text based passwords for the authentication. Two conflict cases of traditional password i.e. if user choose simple password it will easy to guess by attacker. The other hand, if a password is strong then it is often hard to remember for user. Instead of a text password user will be choose graphical password scheme that uses MD5. In MD5 images that converted into binary code. Here binary code will be the password for user. Thus, graphical password is secure than existing graphical password techniques because every time user needs to enter different set of code for authentication i.e. every time new password gets generated making Dictionary attacks, Brute Force attack, and other attacks infeasible. Because of these advantages, there is a growing interest in graphical password. In addition user can use ?document sharing? feature after authentication process and also graphical passwords can be applied to workstation, web log-in applications, ATM machines and mobile device

CMAPS: A Chess-Based Multi-Facet Password Scheme for Mobile Devices

It has long been recognized, by both security researchers and human-computer interaction researchers, that no silver bullet for authentication exists to achieve security, usability, and memorability. Aiming to achieve the goals, we propose a Multi-fAcet Password Scheme (MAPS) for mobile authentication. MAPS fuses information from multiple facets to form a password, allowing MAPS to enlarge the password space and improve memorability by reducing memory interference, which impairs memory performance according to psychology interference theory. The information fusion in MAPS can increase usability, as fewer input gestures are required for passwords of the same security strength. Based on the idea of MAPS, we implement a Chess-based MAPS (CMAPS) for Android systems. Only two and six gestures are required for CMAPS to generate passwords with better security strength than 4-digit PINs and 8-character alphanumeric passwords, respectively. Our user studies show that CMAPS can achieve high recall rates while exceeding the security strength of standard 8-character alphanumeric passwords used for secure applications
