A graphical password authentication system (ieee 2011) 1Shaibi Varkey
The document proposes a graphical password authentication system that combines graphical and text-based passwords. It describes how the system works: users select points of interest (POIs) on an image and associate text with each during registration. For login, users must correctly select the POIs in the correct order and provide the associated text. The system was implemented using Visual Basic .NET and aims to achieve the memorability of graphical passwords with the security of text-based passwords through multiple authentication factors.
Password is a secret word or string of characters used to authenticate identity and access resources like accounts, emails, apps, networks, websites and databases. Common types of authentication include token-based using keys or cards, biometric using fingerprints or facial recognition, and knowledge-based using text or graphical passwords, which are the most widely used. Graphical passwords present images and require the user to select or click points in a specific order for authentication. They provide more security than text passwords but also have drawbacks like taking more time and storage and being vulnerable to shoulder surfing.
Authentication Scheme for Session Password using matrix Colour and Text IOSR Journals
The most common method used for authentication is Textual passwords. But textual passwords are
in risk to eves dropping, dictionary attacks, social engineering and shoulder surfing. Graphical passwords are
introduced as alternative techniques to textual passwords. Most of the graphical schemes are helpless to
shoulder surfing. To address this problem, text can be combined with images or colors to generate session
passwords for authentication. Session passwords can be used only once and every time a new password is
generated. In this paper, two techniques are proposed to generate session passwords using text and colors
which are resistant to shoulder surfing. These methods are suitable for Personal Digital Assistants.
Graphical passwords provide an alternative authentication method to alphanumeric passwords. They involve selecting images or points on images to create a password. This survey paper categorizes existing graphical password techniques as either recognition-based, where the user identifies previously selected images, or recall-based, where the user reproduces a previous creation like a drawing. While graphical passwords can be more memorable and secure, challenges include longer registration/login times and vulnerability to shoulder surfing. Proposed solutions to shoulder surfing involve using movable frames or geometric configurations like triangles.
Graphical passwords are an alternative authentication method that uses images instead of text. They are easier for users to remember but take longer to set up and log in. While more secure than text passwords, most schemes are vulnerable to shoulder surfing. However, techniques like movable frames could add security by countering observation. Overall, graphical passwords balance usability and security but require more development to address issues and achieve widespread adoption.

Graphical password authentication system with association of soundVikram Verma
The document proposes a graphical password authentication system that associates sound signatures to enhance security. It involves generating a password by assigning click points on one or more images. The system would then associate an audio file selected by the user. This adds an additional layer of security compared to existing graphical password systems. The proposed system aims to address limitations of previous techniques like predictability, load on databases, and difficulty of remembering complex passwords. It would use SQL server to store user accounts and manage the passwords generated using images and sound files.
Integration of sound signature in graphical passwordParag Tamhane
The document presents a graphical password system that uses images and click points for authentication. Users register by selecting a sequence of images and click points. Their profile is stored as a master vector with their ID, selected sound frequency, and tolerance level, along with a detailed vector of the images and click points. During login, users enter their ID and a sound is played, if the frequency is within the tolerance level they selected, their click sequence is checked against the stored profile for authentication. The system aims to provide a more memorable password while improving security over text passwords.
This document summarizes a thesis on graphical passwords as an alternative to text-based passwords. Graphical passwords use images instead of text and are easier for users to remember. They provide stronger security than text passwords since they are harder to guess via brute force or dictionary attacks. However, graphical passwords are vulnerable to "shoulder surfing" attacks where an observer watches the user enter their password. The document discusses recognition-based and recall-based graphical password techniques and proposes solutions like movable frames to mitigate shoulder surfing risks. It concludes that graphical passwords satisfy the conflicting needs of ease of use and security, but have not been widely adopted and current methods could still be improved.
The document discusses and compares various authentication methods, including recognition-based, recall-based, and graphical password techniques. It provides an overview of common techniques such as Dhamija and Perrig's picture selection scheme, Sobrado and Birget's pass-object selection scheme, and Jermyn et al.'s Draw-A-Secret scheme. While graphical passwords may be easier for users to remember than text passwords, they have limitations such as taking longer to create and register, requiring more storage space, and not being very mature yet compared to traditional text-based passwords. The document evaluates the security and usability of different authentication methods.

The proposed system offers stronger security against online attacks while being easy for users. It is recommended for domains like banking that require enhanced security.
Defence against large scale online guessing attacks using persuasive cued cli...Ayisha M Kalburgi
Why no to text passwords???
Easy to remember ---- Easy to guess.
Users tend to use same password for different accounts.
An Alternative : GRAPHICAL PASSWORDS
->Humans can remember pictures better than text.
->Hard to decode.
->Overcoming SQL Injection.
This summary provides the key details about a research paper on secure user authentication and graphical passwords using cued click-points:
1. The paper proposes a graphical password scheme called Persuasive Cued Click-Points (PCCP) to improve usability and security over text passwords. PCCP aims to discourage users from selecting weak passwords by influencing them to choose more random click points.
2. In PCCP, users select a click point on a series of images to create their password. The system aims to minimize "hotspots" by nudging users to select click points farther from common areas.
3. An evaluation found PCCP passwords were more secure than the original Cued Click
Authentication plays a major role in Digital environment. In this environment we have different methods which generally use alphanumeric characters and special characters for password creation. These methods have some problems like hard to remember password because it has no meaning and easily breakable by third parties or attackers. To address these issues, many techniques for authentication are proposed from which graphical password method is best in terms of cost and usage. Basically, Graphical passwords use images for password creation and it has some demerits like hotspot and shoulder surfing problem. A persuasive cued click-point based method reduces hotspot problem. To prevent persuasive cued click-point based method from shoulder surfing we include one time password. For more user convenience we provide two login
methods one which requires internet and other which does not
require internet.
1) The document discusses graphical passwords as an alternative authentication method to text passwords. Graphical passwords involve selecting images or points on images in a specific order to login.
2) Two main types of graphical passwords are discussed: recall-based, where the user reproduces a secret, and recognition-based, where the user identifies previously selected images. Specific schemes like DAS, PassPoints, and Passfaces are examined.
3) Advantages of graphical passwords include being more secure and harder to guess than text passwords. Disadvantages include taking more time to login, requiring more storage space, and vulnerability to shoulder surfing. Overall, graphical passwords provide a more user-friendly option but still have limitations to widespread adoption

This document discusses authentication methods and focuses on graphical passwords. It begins with an overview of common authentication methods like text passwords, tokens, and biometrics. It then discusses the drawbacks of text passwords and introduces graphical passwords as an alternative. The document surveys recall-based and recognition-based graphical password techniques and provides examples like Draw-A-Secret and Passfaces. It concludes by noting the advantages of graphical passwords in usability and security but also disadvantages like longer login times and storage requirements.
This document discusses cued click point authentication, a graphical password technique that aims to address the hotspot problem of traditional click-based passwords. It consists of five click points across five different images, rather than on a single image like PassPoint. This is designed to reduce attackers' ability to guess passwords based on common click locations. The document provides an overview of passwords and authentication methods, describes recognition-based and recall-based graphical passwords including PassPoint, discusses the hotspot problem with PassPoint, and introduces cued click point as an alternative approach.
This document describes a graphical password authentication system project. The project aims to create a more secure authentication method than traditional text passwords by using images and click points. It will have hardware and software requirements and address problems with standard passwords like dictionary attacks. The objectives are to understand human memory for visual information and have users click points on an image as their password. It will provide security advantages over text passwords and be more user-friendly.
This document discusses graphical password authentication methods. It outlines recognition-based and recall-based techniques, such as selecting images and recreating drawings. Recognition techniques include picking images and identifying them later. Recall techniques involve reproducing a sequence, like clicking points on an image. The document evaluates the security and usability of different methods. While graphical passwords can be more secure than text passwords, they also take longer and are vulnerable to shoulder surfing. Potential solutions to shoulder surfing involve using movable frames or complex image schemes. Overall, the document argues that graphical passwords provide an alternative to text passwords but require more research.
This document describes a new password authentication method that combines textual passwords with a modified cued click points technique for increased security. The method uses a special key display interface that breaks the user's password into a combination of four passwords plus three additional strings. These seven strings are then encrypted using a novel one-way encryption algorithm called One-time Data Division (ODD). This produces a 256-character encrypted password that is stored in the database for authentication. The encryption is complex and lossy, making the original password irrecoverable even by an administrator. The method aims to provide strong security while maintaining usability.
Authentication Using Graphical Passwordijceronline
This paper introduces image based captcha to protect user data or unauthorized access of information. In that password is created from images and text password. Current system is based on only text password but it has disadvantages small password mostly used and easy to remember. This type of password is easy to guess through different attack i.e. dictionary attack and brute force attack. In this paper we have proposed a new image password scheme. In this Recognition based technique is used with numerical password which provide more security and easy to remember text and graphical password.
IRJET-PASSMATRIX- An Authentication System to Resist Shoulder Surfing AttacksIRJET Journal
This document presents a new authentication system called PassMatrix that aims to resist shoulder surfing attacks. PassMatrix uses multiple images where the password is defined as click points on each image. For each login session, the user must scroll horizontal and vertical bars to select the password image, guided by a randomly generated hint. If an incorrect image is selected, a wrong image is displayed as a warning. The system was implemented on Android and evaluated based on accuracy and usability compared to existing techniques. Results found over 75% accuracy and average login times of under 2 seconds, showing PassMatrix can effectively resist shoulder surfing while maintaining usability.

separable reversible data hiding in encrypted imageZTech Proje
This document proposes a method for separable reversible data hiding in encrypted images. The method uses different keys for image encryption and data hiding, allowing the data and original image to be retrieved independently. This improves on existing systems that use the same key for encryption and data hiding, allowing anyone with the key to access both the hidden data and original image. The proposed method encrypts images with an encryption key, then hides data in the encrypted images with a separate data hiding key. Receivers with the data hiding key can retrieve the hidden data, and receivers with the encryption key can retrieve the original image, without extracting the hidden data.

1. DESIGN AND IMPLEMENTATION OF PERSUASIVE CUED
CLICK-POINTS AND EVALUATION OF A
KNOWLEDGE-BASED AUTHENTICATION MECHANISM
OBJECTIVE:
The objective of this project is to provide the security for any websites by
using graphical passwords with view port and persuasive cued click-points.
PROBLEM DEFINITION:
The problem with this scheme is that the number of predefined regions is
small, perhaps a few dozens in a picture. The password may have to be up to 12
clicks for adequate security, again tedious for the user. Another problem of this
system is the need for the predefined regions to be readily identifiable.
ABSTRACT:
In this project, a graphical password system with a supportive sound
signature to increase the remembrance of the password is discussed. In proposed
work a click-based graphical password scheme called Cued Click Points (CCP) is
presented. In this system a password consists of sequence of some images in which
user can select one click-point per image. In addition user is asked to select a
sound signature corresponding to each click point this sound signature will be used
to help the user in recalling the click point on an image.
2. EXISTING SYSTEM:
In the existing system, Brostoff and sasse carried out an empirical study of
passfaces, which illustrates well how a graphical password recognition system
typically operates. Blonder-style passwords are based on cued recall. A user clicks
on several previously chosen locations in a single image to log in. As implemented
by Passlogix Corporation, the user chooses several predefined regions in an image
as his or her password. To log in the user has to click on the same regions in effect,
cued click points (ccp) is a proposed alternative to passpoints. In ccp, users click
one point on each of 5 images rather than on five points on one image. It offers
cued-recall and introduces visual cues that instantly alert valid users if they have
made a mistake when entering their latest click-point (at which point they can
cancel their attempt and retry from the beginning). It also makes attacks based on
hotspot analysis more challenging. Each click results in showing a next-image, in
Effect leading users down a “path” as they click on their sequence of points. A
wrong click leads down an incorrect path, with an explicit indication of
authentication failure only after the final click. Users can choose their images only
to the extent that their click-point dictates the next image.
While the predictability problem can be solved by disallowing user choice
and assigning passwords to users, this usually leads to usability issues since users
cannot easily remember such random passwords. Number of graphical password
systems have been developed, Study shows that text-based passwords suffers with
both security and usability problems
3. DISADVANTAGE:
The problem with this scheme is that the number of predefined regions is
small, perhaps a few dozens in a picture. The password may have to be up to 12
clicks for adequate security, again tedious for the user. Another problem of this
system is the need for the predefined regions to be readily identifiable.
PROPOSED SYSTEM:
In the proposed work we have integrated sound signature to help in recalling
the password. No system has been devolved so far which uses sound signature in
graphical password authentication. Study says that sound signature or tone can be
used to recall facts like images, text. In daily life we see various examples of
recalling an object by the sound related to that object enters User ID and select one
sound frequency which he want to be played at login time, a tolerance value is also
selected with will decide that the user is legitimate or an imposter. To create
detailed vector user has to select sequence of images and clicks on each image at
click points of his choice. Profile vector is created.
ADVANTAGE:
To create detailed vector user has to select sequence of images and
clicks on each image at click points of his choice. Profile vector is
created.
4. Users preferred CCP to Pass Points, saying that selecting and
remembering only one point per image was easier and sound signature
helps considerably in recalling the click points.
System showed very good Performance in terms of speed, accuracy,
and ease of use.
