Puzzle Based Password Authentication by using Grid Selection

Abstract

Passwords are ubiquitous today on any platform, on possibly any website. But to remember so difficult passwords and that too on numerous websites seems daunting and therefore you can devise a graphical password strategy. This will allow the user to set passwords in the form of graphical presentation in a certain pattern and later use that pattern to login into the system.  In this method, the user is required to select some images (let’s say different chocolates) in a specific pattern (for example dairy milk is followed by 5 stars which are in turn followed by KitKat and so on). The next time the user tries to log in, the images would have been shuffled, but the user will be required to follow the same pattern which was used initially. Every time the user will have to use the same sequence while the images are placed in different ways. This type of authentication is difficult to break since neither brute force nor dictionary attacks could breach it. We need techniques that can be easily implemented and provide better results to this process.This technique works in two styles, distorting a single image into multiple pieces where the images need to connect like a puzzle, and the other one is using multiple images and forming a pattern to login. In this method, each time while login user needs to place the image in a particular order which is made during registration time. Then the matched image will be converted into a grid of passcode where the rows and columns will be transposed dynamically. So, it will be difficult for the intruder to crack the passcode. Then the passcode will be matched with the passcode already generated and stored in the server. Passwords are ubiquitous today on any platform, on possibly any website.
