stract: Security for authentication is required to give a superlative secure users’ personal information. This paper presents a model of the Graphical password scheme under the impact of security and ease of use for user authentication. We integrate the concept of recognition with re-called and cued- recall based schemes to offer superior security compared to existing schemes. Click Symbols (CS) Alphabet combine into one entity: Alphanumeric (A) and Visual (V) symbols (CS-AV) is Captcha-based password scheme, we integrate it with recall- based n×n grid points, where a user can draw the shape or pattern by the intersection of the grid points as a way to enter a graphical password. Next scheme, the combination of CS-AV with grid cells allows very large password space (2.4 × 104 bits of entropy) and provides reasonable usability results by determining an empirical study of memorable password space. Proposed schemes support most applicable platform for input devices and promising strong resistance to shoulder surfing attacks on a mobile device which can be occurred during unlocking (pattern) the smartphone

“…A mathematical definition of entropy in terms of the probability distribution function is: (1) where, P(X=x) is the probability that the variable X has the value of x. The entropy is used to determine the difficulty of the password or key [20]. It can be conventionally expressed in bits.…”

“…The password entropy provides a theoretical number representing how unpredictable a password is. The National Institute of Standards and Technology's published guidelines use different variations of entropies to measure password strength (Burr et al, 2004). On the other hand, the password guessability measure indicates the number of guesses required by password-cracking algorithms to guess the given password (Kelley et al, 2012).…”

“…In recent years, the research focus has shifted from the importance of password policy provision to finding the best password policy to implement in PCSs to ensure that usable and strong passwords are created. Researchers have paid close attention to answering this question because the current guidelines are based on theoretical estimates (Burr, Dodson, & Polk, 2004) and not empirical data. Kelley et al (2012) and Komanduri et al (2011) found that usable and strong passwords are created by enforcing a password policy requiring a minimum of 16 characters without any further restrictions, such as including different character classes.…”

The aim of this research is to inform the design and usability of password creation systems (PCSs) and their supporting features so they can better support users when creating passwords. PCSs are a particular class of an interactive system that allow users to create passwords and which may offer supporting features to help users that process. The supporting features include statements of password policy, password creation suggestions, and password strength indicators. The thesis addresses this aim at the user interface level by providing knowledge about how users react to a range of aspects of the supporting features in PCSs and by providing a set of usability heuristics and guidelines to support the evaluation and development of existing PCSs. There were three phases of research, each consisting of studies that provided insights for the next one. The first phase focused on understanding current practices in PCSs and their effects on users. The outcome of this phase revealed a high number of usability problems including lack of supporting features, design presentation flaws, and ambiguity in password instructions. The second phase investigated the effects of different design aspects in PCSs. The findings showed that different design aspects of PCSs had a significant effect on the usability and password strength in different ways.The third phase proposed a set of usability heuristics and guidelines specifically for the evaluation and design of PCSs. The heuristics were evaluated by usability professionals and were perceived to be easy to understand, clear, and useful. A mixture of qualitative and quantitative methods was used to answer the research questions. The findings suggest that PCSs can effectively support users in creating passwords by addressing four key factors: (1) provision of supporting features, (2) user instructions for creating passwords, (3) timing of presentation for presenting statements of policy and creation suggestions, and (4) media and colour scheme for designing strength indicators. vi vii Contents
