USER AUTHENTICATION THROUGH CUED CLICK POINTS BASED GRAPHICAL PASSWORD

User authentication is a fundamental component in most computer security context. In recent years, computer and network security has been formulated as a technical problem. A key area in security research is authentication which is the determination of whether a user should be allowed access to a given system or resource. In this respect, Authentication is a process by which a system verifies the identity of a user. Authentication may also be generalized by saying that “to authenticate” means “to authorize”. Users tend to pick passwords that can be easily guessed, on the other hand, if a password is hard to guess, then it is often hard to remember. To address this problem some researchers have developed authentication methods that use pictures as passwords, known as graphical passwords.Graphical passwords are a proposed alternative to text passwords that have been shown to have good usability and security properties that use images for login, and leverage the picture superiority effect for good usability and memorability. Categories of graphical passwords have been distinguished on the basis of different kinds of memory retrieval (recall, cued-recall, and recognition). Though there are several kinds of graphical password, But We have choose to implement the cued click based due to efficient and more secured, Cued click points is a click-based graphical password scheme, Users click on one point per image for a sequence of images. The next image is based on the previous clickpoint. Performance was very good in terms of speed, accuracy, and number of errors. Graphical passwords may offer better security than text-based passwords because many people, in an attempt to memorize text-based passwords, use plain words rather than the recommended jumble of characters.

Graphical Password based Authentication System with Sound Sequence

There have been many graphical password schemes proposed as alternatives to text passwords. Research and experience show that alpha-numeric passwords are inefficient with both usability and security issues which limit their application in today’s life. Studies have showed that human brain is much better at recognizing and memorizing images than text. Graphical based passwords are intended to make use of this human characteristic with a goal to reduce the memory burden on users, along with a password space which is offered by images, more secure passwords can be produced and users will be spared of unsafe practices in order to cope. This paper focuses on a new click-based graphical password scheme which is known as Cued Click Points (CCP). It can be viewed as a combination of PassPoints, Passfaces and Story. A password comprises of one click-point per image from a sequence of images. The next image displayed is based on the previous click-point so that the users receive immediate feedback as to whether they are on the correct path when logging in. CCP offers better usability, efficiency and security. Users could quickly create and re-enter their passwords. Another feature of CCP is the immediate feedback telling the correct user whether their latest click-point was correctly entered.

Analysis of Knowledge Based Authentication System Using Persuasive Cued Click Points

In general users tend to choose memorable passwords that are easy for attackers to guess, but strong system assigned passwords are hard for users to remember. In this paper focuses on the integrated evaluation of the Persuasive Cued Click Points graphical password system which including usability and security evaluation on three different level. An important goal of authentication systems is support users in selecting better passwords. Increasing security by expanding the value of effective password space. In the click-based graphical passwords, poorly chosen passwords lead to the emergence of hotspots (image portions where users are more likely to select click-points, allowing attackers to mount more successful dictionary attacks). This paper used persuasion to influence user choice is used in click-based graphical passwords for encouraging users to select more random, and hence more difficult to guess, click-points.

Captcha Authenticated Unwanted MessageFiltering Technique for Social NetworkingServices

The authentication and security mechanism for any application is important. The major function of any security system is to protect the data from unauthorized access. The existing password mechanism based on textual passwords provides low level of security against the unwanted access. One of the alternatives to improve the security and authentication is a graphical based password. One of fundamental issue in day today’s life is Social Networking Services (SNS) to give users the ability to control the messages posted on their own private wall. SNS provide little support to this requirement. In this paper a system with hybrid graphical password system based on captcha technology. Captcha is a standard Internet security technique to protect online emails and other services. Captcha as graphical password known as Carp. Carp is a click-based graphical password. In which a sequence of clicks on an image is used to derive the password. It includes rule-based system, which allows users to customize the filtering criteria and a Machine Learning-based soft classifier automatically labelling messages with content-based filtering

User Privileged CAPTCHA as Graphical Password for Multistage Authentication

Nowadays, user authentication is one of the important topics in information security. In today’s world the password security is very important. For password protection various techniques are available. Cued Click Points are a click-based graphical password scheme, a cued-recall graphical password technique. Users Click on one point per image for a sequence of images. The next image is based on the previous click-point. The passwords which are easy to memorize are chosen by the users and it becomes easy for attackers to guess it, but the passwords assigned by the strong system are difficult for users to remember. Many current systems have low level security, and even then users often devise insecure coping strategies in order to compensate for memorability and usability problems. Alternatives such as tokens or biometrics raise other issues such as privacy and loss. Various graphical password mechanisms have received considerable attention in response. In this paper describes CAPTCHA authentication is clearly a practical problem. In a new security primitive based on hard AI problems, namely, a novel family of graphical password systems built on top of Captcha technology is call Captcha as graphical passwords.

The major problem of user registration, mostly text base password, is well known. In the login user be inclined to select simple passwords which is frequently in mind that are straightforward for attackers to guess, difficult machine created password mostly complicated to user take in mind. User authenticate password using cued click points and Persuasive Cued Click Points graphical password scheme which includes usability and security evaluations. This paper includes the persuasion to secure user authentication & graphical password using cued click-points so that users select more random or more difficult to guess the passwords. In click-based graphical passwords, image or video frame that provide database to load the image, and then store all information into database. Mainly passwords are composed of strings which have letters as well as digits. Example is alpha-numeric type letters and digits.

Implementation of Knowledge Based Authentication System Using Persuasive Cued Click Points

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. System showed very good Performance in terms of speed, accuracy, and ease of use. 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. Keywords - Security, Graphical password, Persuasive Cued Click Points.

Persuasive Cued Click-Points: Design, Implementation, and Evaluation of a Knowledge-Based Authentication Mechanism

This paper presents an integrated evaluation of the Persuasive Cued Click-Points graphical password scheme, including usability and security evaluations, and implementation considerations. An important usability goal for knowledge-based authentication systems is to support users in selecting passwords of higher security, in the sense of being from an expanded effective security space. We use persuasion to influence user choice in click-based graphical passwords, encouraging users to select more random, and hence more difficult to guess, click-points.

Exploiting predictability in click-based graphical passwords*

We provide an in-depth study of the security of click-based graphical password schemes like PassPoints (Weidenbeck et al., 2005), by exploring popular points (hot-spots), and examining strategies to predict and exploit them in guessing attacks. We re

User interface design affects security: patterns in click-based graphical passwords

Design of the user interface for authentication systems influences users and may encourage either secure or insecure behaviour. Using data from four different but closely related click-based graphical password studies, we show that user-selected passwords vary considerably in their predictability. Our post-hoc analysis looks at click-point patterns within passwords and shows that PassPoints passwords follow distinct patterns. Our analysis shows that many patterns appear across a range of images, thus motivating attacks which are independent of specific background images. Conversely, Cued Click-Points (CCP) and Persuasive Cued Click-Points (PCCP) passwords are nearly indistinguishable from those of a randomly generated simulated dataset. These results provide insight on modeling effective password spaces and on how user interface characteristics lead to more (or less) security resulting from user behaviour.
