Atm keypad password#

There are many authentication methods, such as password authentication, biometric authentication, signature authentication, and so on, to protect cloud usersвЂ™ data. The authentication system is one of the most important methods for maintaining information security in smart devices.

Furthermore, the security of the proposed scheme was challenged through an experiment wherein three different attackers, having a complete understanding of the proposed scheme, attempted to crack the technique via shoulder surfing, guessing, and camera attack, but they were unsuccessful. The usability score of GRA-PIN was analyzed to be as high as 94%, indicating that it is more reliable and user friendly.

In the study, we have conducted a comparative study between the GRA-PIN scheme with existing PIN-based and pattern-based (swipe-based) authentications approaches using the standard Software Usability Scale (SUS). The feature of simple arithmetic operations (addition and subtraction) is incorporated in the proposed scheme, through which random passwords are generated for each login attempt. This paper describes an innovative, hybrid, and much more robust user authentication approach, named GRA-PIN (GRAphical and PIN-based), which combines the merits of both graphical and pin-based techniques. Being difficult to guess and more user-friendly, graphical passwords have grown in popularity as an alternative to all such textual passwords. Personal Identification Number (PIN)-based and alphanumeric passwords are simple to remember, but at the same time, they are vulnerable to hackers. As a result of the increased use of mobile devices, most people tend to save sensitive and secret information over such devices.

In many smart devices and numerous digital applications, authentication mechanisms are widely used to validate the legitimacy of usersвЂ™ identification. The use of graphical passwords, adds more operations to the information systems to deal with the images used and the determination of the selected region by the users or to manage and record the steps that the user performed to choose the correct sequence of the specified. The user selects points or regions in the image, determines specific shape or arranges the displayed shapes (see figure 2). This password includes the use of images or shapes to determine the user's password.

Traditional textual passwords are applied in information systems due to ease of use and remember, but some researchers tried another direction by proposing graphical password techniques as an alternative to textual password methods. Based on the type of the password, the user password authentication schemes are classified into: textual passwords and graphical passwords. (2) Recording attacks, which the authentication password has been recorded by a camera device for later analysis. The shoulder surfing attack is categorized into two classes: (1) Direct observation attack, which authentication password is determined by an adversary who is directly monitoring the login interface. The key challenge is to protect user's password from being stolen by shoulder surfing attackers. All that in order to give the user adequate level of security against the shoulder surfing. Furthermore, companies that produced ATMs are constantly trying to redesign the keypad in a new form or add more tools (ATM keypad protector as walls that surround the keypad). One of the threats facing the user while using an ATM, especially when entering the password is the shoulder surfing. This keypad adds more cost to the total cost of production of these machines. the Automated Teller Machines (ATMs) are usually designed to include a keypad that is mainly used to enter the password of the card (see figure 1).
