Sandip Foundation’s Sandip Institute of Technology & Research Centre Indian Sandip institute of Technology & Research Centre, Mahiravani, Trimbak road, Nashik, Maharashtraįollowing specification particularly describes the invention and the manner in which it is to be performed. Virtual Shuffling Keypad Using Graphical LCD for Secure ATM Virtual shuffling keypad using graphical LCD for securing ATM which provides a shuffling keypad whose key arrangement will change after every use, even if in last use the password was not accepted wherein every time user use the keypad next time he gets different layout.Ī)ğor shuffling keypad of the ATM machine we use the linear random function in C language, which can shuffle the arrangement of the digits on the ATM machine keypad ī) By using linear random algorithm we can successfully shuffle the arrangement of digits on ATM machine Ĭ) User password cannot easily hack by using such a technique like Key logger, Screen shots detectors and others spy programs which are running in background ĭ) The proposed approach provides protection against key loggers, over the shoulder spoofing, screen capturing after click event.Ī)Ěs against the current implementation of un-shuffled arrangements of digits, in our proposed approach we shuffle the keypad after every click ī) As a result if a person is standing behind to spoof the password over the shoulder, he cannot remember the password since the layout and arrangements of digit change after every click Ĭ) Also noting the coordinate would be of no help since even if the position is noted, the next click would again reshuffle the keypad ĭ) Thus if “4” was currently at position, the next click would have some other digit at the same position. Following invention is described in detail with the help of Figure 1 of sheet 1 showing the shuffled arrangement of digits after every click and Figure 2 of sheet 2 showing the sequence diagram.ġ. Every time you use the keypad next time you will get different layout. Our idea is to implement a shuffling keypad whose key arrangement will change after every use, even if in last use the password was not accepted. Not only in ATM, we are using keypads at many places and our own finger movements are putting our security at risk, for this problem we have come up with an innovative solution of shuffling keypad which will confuse the culprits and they would not be able to detect the password from our finger movements on the keypad. ![]() Or low lying persons can intentionally note you finger movements on the keypad and try to guess the password. As in all keypad based access system or authentication system there are high chances of password being overseen by unknown person who are standing near you. Present invention provides virtual shuffling keypad using graphical LCD. ![]()
