PASSMATRIX An Authentication System to Resist Shoulder Surfing Attacks

authentication method. Strong textual passwords are hard to memorize. To address the weakness of textual password graphical passwords are proposed. Click based or pattern based approaches are widely used techniques for mobile authentication system. Such textual and graphical passwords a scheme suffers from shoulder surfing attacks. Attacker can directly observe or can use video recorder or webcam to collect password credentials. To overcome the problem, shoulder surfing attack resistant technique is proposed. This technique contains pass-matrix. More than one image are used to set the password. For every login session, user needs to scroll circulatory horizontal and vertical bars. A password hint is provided to the user to select desired image password grid. Horizontal and vertical scroll bar covers the entire scope of pass-images. For password selection, password hint and horizontal and vertical scroll bar are used. The proposed technique is implemented on android platform. The system performance is measured using memorability and usability of a password scheme with respect to the existing technique.

Implementation of Passmatrix Based Shoulder Surfing Resistant Graphical Authentication System

Implementation of Passmatrix Based Shoulder Surfing Resistant Graphical Authentication System

Overcomes this problem we have utilized a safe graphical verification system named as PassMatrix Based Shoulder Surfing Resistant Graphical Authentication System that are protecting users from getting to be casualties of shoulder surfing attacks while contributing passwords in public through the use of one-time login pointers. In this user have set their graphical password at registration time and when a user login user must require two factor authentications. User can scan the QR code and download image in their mobile then user have selected the pass-image same as when selected at the time of registration.[9] If selected pass-image is correct then user login into the system. A login marker will randomly create for every passer-image and will be pointless after the session ends. The login marker will gives better security against shoulder surfing attacks, since users utilize a dynamic pointer to call attention to the position of their passwords instead of tapping on the password object directly. Due to this user access their data more secure. The main purposed of our system to maintain the privacy and authority of the user.

Implementation of Graphical Authentication System for Shoulder Surfing Attacks

Implementation of Graphical Authentication System for Shoulder Surfing Attacks

ABSTRACTAuthentication based on passwords is used largely in applications for computer security and privacy. However, human actions such as choosing bad passwords and inputting passwords in an insecure way are regarded as ’weakest link’ in the authentication chain. Rather than arbitrary alphanumeric strings, users tend to choose passwords either short or meaningful for easy memorization. With web applications and mobile apps piling up, people can access these applications anytime and anywhere with various devices. This evolution brings great convenience but also increases the probability of exposing passwords to shoulder surfing attacks. Attackers can observe directly or use external recording devices to collect users’ credentials. To overcome this problem, we proposed a novel authentication system pass matrix, based on graphical passwords to resist shoulder surfing attacks. With a one-time valid login indicator and circulative horizontal and vertical bars covering the entire scope of pass-images, pass matrix offers no hint for attackers to figure out or narrow down the password even they conduct multiple camera-based attacks. We also implemented a pass matrix prototype on Android and carried out real user experiments to evaluate its memorability and usability. From the experimental result, the proposed system achieves better resistance to shoulder surfing attacks while maintaining usability.

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

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

We introduced a graphical authentication system called PassMatrix. In PassMatrix, a password consists of only one pass-square per pass-image for a sequence of n images. The number of images (i.e., n) is user-defined. In PassMatrix, users choose one square per image for a sequence of n images rather than n squares in one image as that in the PassPoints scheme.

ABSTRACT: Authentication based on passwords is used largely in applications for computer security and privacy. However, humanactions such a choosing wrong passwords and inputted passwords in an not secure way are regarded as” the weakest connection” in theauthentication chain. Rather than arbitrary alphanumeric character, users tend to select a password either short or his name related for easymemorization. With web site applications and mobile phone apps charging up, peoples can get access this typeof application anytime and anywhere with multiple devices. This evolution brings good convenience but also improves the probability of exposing passwords to shoulder surfingattacks. Attackers can observe directly or use external recording devices to collect users’ credentials. To come this problem, weproposed a novel authentication system Pass Matrix, based on graphical passwords to resist shoulder surfing attacks. Many authentications methods are presented, but users are familiar with textual password method. Textual password methods are vulnerable to shoulder surfing andkey loggers. To come this problem many other authentication system like token based authentication, biometric bases authentication systems, graphical password methods have been proposed.

A Sophisticated Approach to Graphical Password

A Sophisticated Approach to Graphical Password

As the mobile marketing statistics compilation by Danyl, the mobile shipments had overtaken PC shipments in 2011, and the number of mobile users also overtaken desktop users at 2014, which closed to 2 billion. However, shoulder surfing attacks have posed a great threat to users’ privacy and confidentiality as mobile devices are becoming essential thing in modern life. People may log into web services and apps in public to access their personal accounts with their smart phones, tablets or public devices, like bank ATM. Shoulder-surfing attackers can observe how the passwords were entered with the help of reflecting glass windows, or alone monitors hanging everywhere in public places. Passwords are exposed to risky environments, even if the passwords themselves are complex and secure. A secure authentication system need to be able to defend against shoulder surfing attacks and should be applicable to all kinds of devices. Authentication schemes in the literature such as those in [6] are resistant to shoulder-surfing, but they have either usability limitations or small password space. The limitations of usability include issues such as taking more time to log in, passwords being too difficult to recall after a period of time, and the authentication method being too complicated for users without proper education and practice. In 2006, Wiedenbeck et al. proposed PassPoints [5] in which the user picks up several points (3 to 5) in an image during the password creation phase and re-enters each of these pre-selected click-points in a correct order within its tolerant square during the login phase. Comparing to traditional PIN and textual passwords, the Pass- Points scheme substantially increases the password space and enhances password memorability. Unfortunately, this method of graphical authentication scheme is vulnerable to shoulder surfing attacks. Hence, based on the PassPoints, we implement the idea of using one-time session passwords and PassMatrix authentication system that is resistant to shoulder surfing attacks.

A Shoulder Surfing Resistant Graphical Verification System

A Shoulder Surfing Resistant Graphical Verification System

In 2010, David Kim et al. [25] proposed a visual authentication plot for tabletop interfaces called "Shading Rings", as appeared in Figure 3(a) (the figure is removed from [25]), where the client is doled out I validation (key) symbols, which are all in all relegated one of the four shading rings: red, green, blue, or pink. Amid login, I networks of symbols are given, with 72 symbols being shown per framework. There is just a single key symbol exhibited in every network. The client must drag every one of the four rings (in a perfect world with pointer and thumb from two hands) simultaneously and put them in the network. The unmistakable key symbol ought to be caught by the right shading ring while whatever is left of rings simply make distraction determinations. The client affirms a determination by dropping the rings in position. The rings are sufficiently extensive to incorporate in excess of one symbol and would thus be able to jumble the immediate onlooker. Tragically, these sorts of passwords can be broken by converging the client's determinations in each login on the grounds that the shade of the doled out ring is settled and a ring can incorporate at most seven symbols. Along these lines, the aggressor just requires a predetermined number of trials to figure the client's secret key.

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

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

Abstract— The user usually uses a password to avoid the attacks like a dictionary attack, brute force attack and shoulder surfing attack which is the famous attack nowadays. The shoulder surfing attack is a direct observation technique by watching over the user’s shoulder when they enter their password to get information. The most common authentication method used by the user is textual password. But, the textual password has many disadvantages because it is vulnerable to attack as it tends to shoulder surfing attack. In this project, a pattern-based password authentication will develop to overcome this problem. Using this scheme, the user needs to select the type of pattern that they like during registration. To log in to their account, the user needs to enter the password in the form of the textual password in ordering manner based on a pattern that they choose during registration. The text password grid presented with a different style as it filled with random objects whether characters, numbers or images. This method is suitable to minimizing shoulder surfing attack as it can improve the security of user’s password and they can efficiently login to the system.

A Shoulder Surfing Resistant Graphical Password System             

A Shoulder Surfing Resistant Graphical Password System             

Authentication is the first security mechanism that can be used to prevent unauthorized access to the system. In addition, textual password (text-based password) is the most famous authentication mechanism which has been used for several years. In this authentication method, a user selects a combination of characters as his password, which is required to memorize by him. However, in order to have a secure password, the generated password must follow several requirements such as minimum 8 characters, a combination of capital and small characters, alphanumeric, using special characters, ... etc. Thus, this makes the password to be complex (e.g. "@bu*%183bDIK), which also makes difficulties for a hacker to guess (dictionary attack) or break (brute force attack) it. Similarly, the generated complex password provides this challenge for the users to memorize it for further access. Thus, the users tend to pen down their long and random passwords somewhere or take the easy passwords instead. Graphical password is an alternative authentication password which can solve the problem of remembering the complex passwords in textual password approach. In this case, several images are used to represent a user password, rather than the text. Later on, upon login to the system, a user can select or produce the same graphic image correctly for accessing to the system. Since remembering the image is easier than the text, the selected images as the password is complex as well as easy to remember by the user at the same time. Additionally, the other advantage of graphical password is to prevent stealing the passwords if a keystroke logger such as malicious software (Trojan) is installed by a hacker in order to capture the text-based passwords. In general, there are three graphical password approaches such as recognition-based, pure recall-based and cued recall based. In the recognition- based approach, the user can pick several images such as icons or symbols which he recently selected in user

Defending Shoulder Surfing Attacks in Secure Transactions Using Session Key Method

Defending Shoulder Surfing Attacks in Secure Transactions Using Session Key Method

A. Bianchi, I. Oakley, and D.-S. Kwon, introduced a Spinlock technique which is novel any model non – visual interaction technique [12] which is used for PIN entry in public terminals such as ATMs, door locks, etc. This is a more secure technique which is resistant to brute force and observation attacks. Spinlock is based on the rotating dial for traditional safe. This system unlocked by input a dial as a clockwise and anticlockwise rotation. The more safe PIN entry will be 2-anti clockwise, 8-clockwise, and 7–clockwise. Spinlock was introduced for the Apple iPhone and iPod touch devices. The users interact with the system by selecting the edge of the circular dial widget and drag the cursor around the rim.

Persuasive Graphical Password Authentication Using Cued Click Point

Persuasive Graphical Password Authentication Using Cued Click Point

A multitude of graphical password schemes have been proposed, motivated by the promise of improved password memorability and thus usability, while at the same time improving strength against guessing attacks. Like text passwords, graphical passwords are knowledge based authentication mechanisms where users enter a shared secret as evidence of their identity. However, where text passwords involve alphanumeric and/or special keyboard characters, the idea behind graphical passwords is to leverage human memory for visual information, with the shared secret being related to or composed of images .There has been a great deal of hype for graphical passwords since two decade due to the fact that primitive’s methods suffered from an innumerable number of attacks which could be imposed easily. Here we will progress down the taxonomy of authentication methods. To start with we focus on the most common computer authentication method that makes use of text passwords. Despite the vulnerabilities, it’s the user natural tendency of the users that they will always prefer to go for short passwords for ease of remembrance [10] and also lack of awareness about how attackers tend to attacks. Unfortunately, these passwords are broken mercilessly by intruders by several simple means such as masquerading, Eaves dropping and other rude means say dictionary attacks, shoulder surfing attacks, social engineering attacks [10][1].To mitigate the problems with traditional methods, advanced methods have been proposed using graphical as passwords. The idea of graphical passwords first described by Greg Blonder(1996). For Blonder, graphical passwords have a predetermined image that the sequence and the tap regions selected are interpreted as the graphical password. Since then, many other graphical password schemes have been proposed. The desirable quality associated with graphical passwords is that psychologically humans can remember graphical far better than text and hence is the best alternative being proposed. There is a rapid and growing interest in graphical passwords for they are more or Infinite in numbers thus providing more resistance.

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

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

Blonder [2] designed a graphical password scheme in which a password is created by having the user click on several locations on an image. During authentication, a user must click on the approximate areas of those locations. The image can assist users to recall their passwords and there-fore this method is considered more convenient than tex-tual passwords. The “PassPoint” system extended Blon-der's idea by eliminating the predefined boundaries and al-lowing arbitrary images to be used [13, 14, 15]. As a result, a user can click on any place on an image (as opposed to some pre-defined areas) to create a password. A tolerance around each chosen pixel is calculated. In order to be au-thenticated, the user must click within the tolerance of the chosen pixels.

that have been proposed which are support to shoulder surfing but have their own drawbacks is taking more time for user to login or usability issues. The user is authenticated using session password. Session passwords are the password that is provided to authenticate the user for a session. Session passwords are used only once. Every time the users enter a session he has to input different password. Once the session is over that password becomes is of no use for next session and the current session gets terminated. Session password provide more security as every time the session start a new password is created and they are not prone to dictionary attacks ,brute force attacks and shoulder surfing attacks. In Authentication, the user has to submit correct credentials which are already stored in the system.

A Pattern-Based Multi-Factor Authentication System

A Pattern-Based Multi-Factor Authentication System

5. Conclusions and Future Works. User authentication is one of the most important component of a secure system. Even after the development of advanced authentication mechanisms such as biometrics, the traditional concept of passwords still continues to be the most widely adopted means for user authentication. Owing to the limitations and weaknesses of text-based passwords such as smaller password space, susceptibility to brute force and shoulder surfing attacks, etc., this paper proposes a novel pattern-based multi-factor authen- tication scheme that involves the use of a combination of textual and graphical passwords. The proposed system has a larger password space and is secure against dictionary attacks since it involves additional mouse input along with keyboard input. Moreover, a brute force attack would require automatic generation of all possible mouse-click and text combination in order to crack the actual password. This renders the bruce force attack infeasible for the proposed system.
