Implementation of Passmatrix Based Shoulder Surfing Resistant Graphical Authentication System

The Deja Vu system, proposed by Dhamija and Perrig in the year 2000, takes advantage of the human ability to remember images even if seen for a short duration of time. It uses random art images, which are hard to describe to reduce the likelihood of users writing down their password images or telling it to another person. Users are presented with a grid during the authentication session where they have to choose their password images among distracting images during individual login attempts. Similar to the Pass-faces system, the Deja Vu system is vulnerable to shoulder-surfing attack as the users select their password images for each of the authentication sessions. Guessing attack is also possible if the adversary knows the user well. [3] In 2005, Susan Wiedenbeck et al. Introduced a graphical authentication scheme Pass-points and at that time, handheld devices could already show high resolution colour pictures. Using the PassPoint scheme, the user has to click on a set of pre-defined pixels on the predestined photo with a correct sequence and within their tolerant squares during the login stage. [8]

DIGITAL LOCK: A HYBRID AUTHENTICAIONMr. Dipak P. Umbarkar1, Prof. Megha singh2

Textual password is the most common technique used for authentication. The weaknesses of this technique likely produce eves dropping, social engineering, dictionary attack and shoulder surfing are well-known. Unpredicted and long passwords can make the system protected. On the other hand the main problem is the trouble of memorizing those passwords. Studies have uncovered that users have a tendency to choice small and stress-free password to recall. Fatefully, these passwords can be easily predicted or broken. Other techniques uses are graphical passwords and biometrics. On the other hand these methods have their particular drawback. In Biometrics password techniques such as facial recognition, finger prints etc. have been offered but not yet generally adopted. The main disadvantage of this method is that such systems can be valuable and slow. There are numerous graphical password methods that are planned in the past years. On the other hand most methods are suffered from shoulder surfing attack which is becoming relatively a large problem. There are some graphical passwords patterns that are resistant to shoulder- surfing but they have their particular weaknesses like usability problems or takes large time for login or it has tolerance levels The shoulder surfing attack in an attack that can be performed by the adversary to obtain the user’s password by watching over the user’s shoulder as he enters his password. From the time many graphical password methods with different degrees of resistance to shoulder surfing has estimated, e.g., [2] [3] [4] [5][6][7][8][9], and each has its pros and cons. As expected password schemes are vulnerable to shoulder surfing, Sobrado and Birget [2] proposed three shoulder surfing resistant graphical password methods. Maximum users are using text-based passwords than graphical passwords, Zhao et al. [10] proposed S3APS text-based shoulder surfing resistant graphical password methods. In S3PAS, the user has to combine his textual password on the login screen to catch the session password but the login procedure of Zhao et al.’s methods is hard and boring. And then, a number of text-based shoulder surfing resistant graphical password methods have been proposed, such as [11][12][13][14][15]. Undesirably, none of present textual based shoulder surfing resistant graphical password schemes is both protected and effectual adequate. In this paper, we will suggest a better text-based shoulder surfing resistant graphical password structure by with colors and session. The process of the proposed methods is simple and easy to study for users aware with word-based passwords. The user can easily and efficiently to login the system without using any physical keyboard.

Safe validation of shoulder surfing using the concept of secret password with PassMatrix

Current authentication systems suffer from many weaknesses. Text-based passwords are the most common way to secure access to protected resources. The limitations of text-based passwords are well known. For example, a secure text-based password must be random and formed using a combination of uppercase, lowercase, and special characters. [2]However, secure passwords are hard to

anywhere. The security of passwords in cued recall system depends on the image selected for authentication. Generally, images will be having limited number of clickable points for password selection which reduces the password space and in turn, passwords are vulnerable to password guessing attacks. These are vulnerable to password capturing attacks because entire password or user’s portfolio will be displayed for every login which can be observed by the intruders. Password creation and login times are more compared to recall systems. The details collected for various graphical authentication techniques from different sources (approximate values) and shoulder surfing systems were given in bellow tables. Each technique has its own way for evaluation of usability and security.

A Sophisticated Approach to Graphical Password

A Sophisticated Approach to Graphical Password

Users can set up a complex authentication password and are capable of reentering it after a long time even if the memory is not use periodically. However, most of these image-based passwords not secure because of shoulder surfing attacks (SSAs). This type of attack either uses direct observation, such as watching over someone or applies video capturing techniques to get passwords, PINs, or other personal information .All human actions such as choosing bad passwords or inputting passwords in an insecure way for later logins are regarded as the weakest link in the authentication mechanism [8]. An authentication scheme which is designed to overcome these vulnerabilities named PassMatrix that protects users from becoming victims of peeping attacks when inputting passwords in public through the usage of one-time login indicators.

Graphical password schemes design: enhancing memorability features using autobiographical memories

Graphical password schemes design: enhancing memorability features using autobiographical memories

There is a commonly known tradeoff between memorability and security of password authentication systems. Being that more secure passwords are less memorable. To redeem this flaw, a number of authentication methods and techniques has been put forward but memorability and security issues still remain as each limitations. These two factors influence the success of passwords. Many schemes are not memorable just because the required memory feature does not portray what people remember most in their design. In the light of this , we have proposed authentication system which is based on autobiographical memories of the users to improve memorability of graphical passwords and randomly generated digits are displayed on the screen for user to enter digits corresponding to the password via keyboard rather than graphical input devices like mouse and stylus in order to resist shoulder surfing attack. Currently we are working on the scheme implementation and performance analysis in order to address some important issues like memorability , security and even the user’s factor of our scheme and they will be published soonest.

Implementation of Shoulder Surfing Graphical Password Schemas Using VSK and OTP, LTP Verification

Implementation of Shoulder Surfing Graphical Password Schemas Using VSK and OTP, LTP Verification

An OTP [6] is a password as the name suggests that is valid scheme for authentication to next process of only one login transaction or session with the system. OTPs remove a number of shortcomings or limitations that are same with alphanumeric old and commonly used “static” passwords. The vital limitation or shortcoming that is overcome or noticed by OTPs is in contrast to generally used alphanumeric static passwords, they are not prone or vulnerable to replay attacks. That means even a potential intruder who can analyse to record an OTP somehow if possible, that was already previously used to log into a service or the system or to conduct a transaction will not be able to forge it since, it will be no longer valid data for transaction. On the other section, OTPs are also difficult for us to remember for long time. Therefore they require advance technology to work. How to generate OTP code and distribute to the individual user? OTP distribution and generation algorithms generally make use of pseudo randomness. This is necessary because if we don’t do so, it would be very easy and simple to guess future generated OTPs by analysing and observing the previous ones. Random and concrete OTP algorithms vary smartly in their workings.

Secured Hybrid Authentication Schemes using Session Password and Steganography

Secured Hybrid Authentication Schemes using Session Password and Steganography

ABSTRACT: The most common method is textual passwords that were used for authentication. Unfortunately, these passwords can be easily guessed or cracked. The next best techniques are graphical passwords. Since, there are many graphical password schemes that are proposed in the last decade, But most of them suffer from shoulder surfing which is also a big problem. Also, there are few graphical passwords schemes that have been proposed which are resistant to various attacks. In this paper two new authentication schemes are proposed with steganography algorithm for any transaction . Any authentication process gets very secure when two or three techniques used together for a system. For every login process, user input different passwords. We proposed two different shoulder surfing resistance graphical password authentication scheme methods one is AS3PAS and second is hybrid textual scheme using color code also Advanced LSB which removes the drawback of simple LSB that it supports all image format.

A Survey On Resisting Shoulder Surfing Attack Using Graphical Password

A Survey On Resisting Shoulder Surfing Attack Using Graphical Password

In order to protect users’ digital property, authentication is required every time they try to access their personal account and data. However, conducting the authentication process in public might result in potential shoulder surfing attacks. Even a more complex password can be cracked easily through shoulder surfing. Using traditional textual passwords or PIN method, users need to type their passwords to validate themselves and thus these passwords can be revealed easily if someone peeks over shoulder or uses video recording devices such as cell phones or google glass. To overcome this problem, we proposed a shoulder surfing resistant authentication system based on graphical passwords, named PassMatrix and PairBased. Using a one-time login indicator per image, users can point out the location of their pass-square without directly clicking or touching it, which is an action vulnerable to shoulder surfing attacks. Because of the design of the horizontal and vertical bars that cover the entire pass image, it offers no clue for attackers to narrow down the password space even if they have more than one login records of that account.

CUED CLICK POINT (CCP) ALGORITHM FOR GRAPHICAL PASSWORD TO AUTHENTICATE SHOULDER SURFING RESISTANCE

In paper[1] author T, R.Nagendran, implemented system in which password is selected block of the image called the view port. But this system failed to secure from hotspot attack. In paper[2] author N. López, M. Rodríguez, C. Fellegi, D. Long. proposed a graphical authentication systems in even odd form.Still unable to resist from shoulder surfing.In paper [3]author S. Man, D. Hong, and M. Mathews, proposed that user should rate colors from 1 to 4 for password and he can remember it as “RGBY”. But the interface is quite difficult to understand to the normal user.In paper [4]author M.Shreelatha, M.Sashi proposed a methodology on Session password which can be used only once,but this technique is proposed to generate session passwords using text which fails to resist shoulder surfing. In paper [5] author, Ushir Kishori Narhar, Ram.B.Joshi proposed a methodology using user name with graphical password using persuasive cued click points along with biometric authentication using finger nail plate.. But biometrics such as face and fingerprints can easily be recorded and potentially misused by biometrics experts without user’s consent. Inpaper [6] Author, Neha Singh, Nikhil Bomanwar proposed a methodology of a persuasive cued click point which reduces the hotspot problem, but provides no security mechanism for shoulder surfing attack .Inpaper[7] Author, Hung- Min Sun, Shiuan-Tung Chen, Jyh-Haw Yeh proposed a system based on authentication system Pass Matrix, based on graphical passwords with a one-time valid login indicator. But this System does not resist the shoulder surfing attack and also vulnerable to smudge attack.

ABSTRACT: Authentication based on passwords is used largely in applications for computer security and privacy. However, human actions such as choosing bad passwords andinputting passwords in an insecure way are regarded as the weakest link in the authentication chain. As people can access their application anytime and anywhere,it increase the probability of exposing password to shoulder surfing attack. To overcome this problem, we proposed a novel authentication system based on graphical passwords to resist shoulder surfing attacks. In our system Authentication process is carried out by threetechniques: CCP based Authentication, Doodle Based Intersection, and PassBYOP.

A Shoulder Surfing Resistant Image Augmented Multi Password Authentication System with Key Store Time Log in & Coordination Comparison

The general concept behind a token-based authentication system is simple. Allow users to enter their user name and password in order to obtain a token which allows them to fetch a specific resource without using their user name and password. Once their token has been obtained, the user can offer the token which offers access to a specific resource for a time period to the remote site. Method of Loci. It also uses recall based technique. IBA is based on a user’s successful identification of his image password set. After the user name is sent to the authentication module, it responds by displaying an image set, which consists of images from the user’s password set mixed with other images. The user is authenticated by correctly identifying the password images. The human brain is more adept in recalling a previously seen image than a previously seen text.

A Pattern-Based Password Authentication Scheme for Minimizing Shoulder Surfing Attack

A Pattern-Based Password Authentication Scheme for Minimizing Shoulder Surfing Attack

Shoulder surfing attack can be minimized using text and color based on graphical password scheme that was proposed by [24]. This method needs the user to choose the length of the password which is between 8 to 15 characters and chooses one color as his pass color from 8 colors that are given by the system. As the seven colors remaining, it will be the decoy colors. As usual, users also need to register an e-mail address for re-enabling his account when he enters a wrong password. The most important things in this scheme are user need to carried the registration process in an environment that is free from shoulder surfing. During the login process, a circle will display which is composed of 8 sectors of equal size when a user sends a login request. The colors of the arcs of each sector are different that can be identified by the color of its arc. Besides, there is a button for rotating the circle clockwise, anti-clockwise, the “confirm” button and the “login” button as well [24]. The user has to rotate the sector which contains the characters of the password and has to move the character in the sector which color is selected by the user until they have their password. As the conclusion, the system that proposed which uses text and color based graphical password is useful to reduce the shoulder surfing attack. Using this authentication method, the user can log in the system without caring about shoulder surfing because they can enter their password without using the physical keyboard. The user can also easily and efficiently login to the system if they use this authentication method as they are familiar with both password scheme that is textual password and color based graphical password.

S3PAS:A Scalable Shoulder-Surfing Resistant Textual-Graphical Password Authentication Scheme

S3PAS:A Scalable Shoulder-Surfing Resistant Textual-Graphical Password Authentication Scheme

In the rule-based scheme, users are able to define their own click-rules when they creating passwords. The primary advantage is that rule-based scheme hides the click-rule. In the basic scheme, the click-rule is open to public, while in rule-based scheme, only the users themselves know their “pass-rules.” As a result, it becomes extremely hard for at-tackers to break user's password using password analysis techniques. Further, the rule-based scheme hides the length |k| of user's password. In the basic S3PAS scheme, if Al-ice's password is |k| in length, she has to click |k| times, which releases her password length to attackers. However, users can protect their password length information well by the rule-based scheme. Another benefit is that it can also avoid the common border problem. In addition, it could be easier for users to remember their own click-rules.

Implementation of Graphical Authentication System for Shoulder Surfing Attacks

Implementation of Graphical Authentication System for Shoulder Surfing Attacks

Current secure systems suffer because they neglect the importance of human factors in security. Author addresses a fundamental weakness of knowledge-based authentication schemes, which is the human limitation to remember secure passwords. Our approach to improve the security of these systems relies on recognition-based, rather than recall-based authentication. Author examines therequirements of a recognition-based authentication system and proposes is more reliable and easier to use than traditional recall-based schemes, which require the user to precisely recall passwords or PINs. Furthermore, it has the advantage that it prevents users from choosing weak passwords and makes it difficult to write down or share passwords with others.

HoneyPass: A Shoulder Surfing Resistant Graphical Authentication System using Honeypot

HoneyPass: A Shoulder Surfing Resistant Graphical Authentication System using Honeypot

Password-based authentication schemes have been most commonly used on many smart devices when compared to other authentication schemes. The lower complexities in implementation, computation, processing requirements and so forth have led to the use of a password-based authentication system. Again, text-based passwords are more commonly used when compared to other existing authentication systems. However, various vulnerabilities were discovered by several cryptanalysts in text-based systems like brute force attack, guessing attack, dictionary attack, social engineering attack etc. In smart phones, the tiny screen size imposes some more constraints such as limited password length, implementation of easier authentication systems to increase performance etc. Moreover, the small on-screen keyboard makes typing inefficient and less precise. Consequently, the users tend to use a smaller password which makes it even more vulnerable. Since the size of smart devices is getting smaller and smaller; few authentication systems cannot be implemented in it due to its size [11].

Shoulder surfing technique of gathering information such as usernames and passwords by watching over a person’s shoulder while he/she logs into the system, thereby helping attackers to gain anaccess to the system. Key logging is the practice of noting the keys struck on keyboard, typically in manner so that person using the system keyboard is unaware that such action is monitored. There are two types of keyloggers viz. software key logger and hardware keylogger. Software keylogger is installed on the computer systems which usually are located between the OS and the keyboard hardware, and every keystroke is recorded.

REVIEW ON COLOR PASSWORD TO RESIST SHOULDER SURFING ATTACK

REVIEW ON COLOR PASSWORD TO RESIST SHOULDER SURFING ATTACK

In 2002, to reduce the shoulder surfing attack, Sobrado and Birget [3] proposed three shoulder surfing resistant graphical password schemes, the Movable Frame scheme, the Intersection scheme, and the Triangle scheme. But from all this schemes, the Movable Frame scheme and the Intersection scheme fail frequently in the process of Authentication. In the Triangle scheme, the user has to select and memorize several pass icons as his password. To login the system, the user has to correctly pass the predetermined number of challenges and in every challenge, the user has to find three pass-icons from a set of randomly chosen icons displayed on the login screen, and then click inside the invisible triangle created by those three pass- icons.
