Comparing the usability of doodle and Mikon images to be used as authenticators in graphical authentication systems

Recognition-based graphical authentication systems rely on the recognition of authenticator images by legitimate users for authentication. This paper presents the results of a study that compared doodle images and Mikon images as authenticators in recognition based graphical authentication systems taking various usability dimensions into account. The results of the usability evaluation, with 20 participants, demonstrated that users preferred Mikon to doodle images as authenticators in recognition based graphical authentication mechanisms. Furthermore, participants found it difficult to recognize doodle images during authentication as well as associate them with something meaningful. Our findings also show the need to consider the security offered by the images, especially their predictability

Shoulder Surfing Resistant Graphical Authentication Scheme for Web Based Applications

Since the design and development of the first graphical authentication pioneered by Blonder in 1996, numerous research has been conducted on this area to be used in different scenarios especially on the Internet. One of the major motivators is the picture superiority which as studies have shown, states that images/pictures provide higher memorability as opposed to Text based authentication. However, graphical authentication is still faced with some challenges. In this paper, a shoulder surfing resistant graphical authentication scheme is proposed to tackle a major issue related to the graphical authentication schemes developed. The proposed scheme provides a high level of resistance to shoulder surfing attacks, mitigating the need to upload pictures and aids in finding chosen objects in the scheme. However, the schemes has some vulnerabilities which implies that there may not be a perfect graphical authentication scheme; each scheme has its merits and demerits making it a suitable candidate for different environment and/or event depending on its architecture

A comprehensive study of the usability of multiple graphical passwords

Recognition-based graphical authentication systems (RBGSs) using images as passwords have been proposed as one potential solution to the need for more usable authentication. The rapid increase in the technologies requiring user authentication has increased the number of passwords that users have to remember. But nearly all prior work with RBGSs has studied the usability of a single password. In this paper, we present the first published comparison of the usability of multiple graphical passwords with four different image types: Mikon, doodle, art and everyday objects (food, buildings, sports etc.). A longi-tudinal experiment was performed with 100 participants over a period of 8 weeks, to examine the usability performance of each of the image types. The re-sults of the study demonstrate that object images are most usable in the sense of being more memorable and less time-consuming to employ, Mikon images are close behind but doodle and art images are significantly inferior. The results of our study complement cognitive literature on the picture superiority effect, vis-ual search process and nameability of visually complex images

Factors influencing graphical user algorithm for mobile banking user authentication: a systematic literature review

The usability and security issues associated with mobile banking user authentication techniques and security have been constantly mentioned. With the increasing number of mobile users, which currently is estimated to be about 500million users by 2015 according to a study done by the Yankee Group in 2011, the main objective of this study is to review studies on mobile banking usability factors and graphical user authentication algorithms on the suitable algorithm to be adopted for mobile banking user authentication. A total of 84 articles were extracted using a predefined search string. A quality criterion was applied on the set of articles and a total of 22 articles were determined for further analysis. 8 factors were determined to influence our scope of research study with the main factors for mobile banking usability being mobile banking user adoption and usability features and for graphical user authentication being graphical passwords and graphical authentication

A NEW APPROACH FOR INSTIGATING SECURITY USING SINGLE ZOOM MOUSE CLICK GRAPHICAL PASSWORD

Due to growing hazards to networked computer system, there is great need for security innovations. Authentication is the process of security to information. User authentication is one of the significant topics in information security. Commonly used authentication is alphanumeric passwords, biometrics and smart card. At present day upcoming popular method is graphical password. In graphical password systems authentication is based on clicking on image rather than typing alphanumeric strings .The motivation to develop graphical password is the fact that human can remember picture better than text. In this we propose a graphical password scheme which is more secured than other method. This method also depends not only on image but also number of mouse click on the image. This method reduces the huge image database, as well as images being too simple to cause collisions on points selected for different users
