“…It has been suggested that a graphical password may be easier to recall that a text-based password [7]. Zheng et al [8] surveyed different techniques to produce graphical passwords such as the click-based scheme which presents the user with an image and requires the user to click various parts of the image in a consistent sequence, or provides different thumbnail images to be selected by the user in a consistent order. The problem with these graphical schemes is that they can still be guessed [9], shared or copied, albeit not as easily as the written password.…”

The use of username-password combinations is the simplest approach to system access to administer but these systems continue to pose several problems to both the user and to the system administrator. Using Biometrics for system access gives greater security as this offers an approach that is more difficult to copy, share or steal. Haptics technology allows these biometric systems to measure also the relative force a user exerts to carry out a task. Studies, to date, using Haptics and Biometrics for user identity verification have been able to attain accuracy of up to 95%, on average. The work presented here has increased this figure by 3%, with the use of a heuristics decision-making algorithm based on the neural network concept. Key features of the heuristics system include allowing either standard or individualized feature selection and permitting imprecision in decision-making to cater for human variability. The study also illustrates that a unique password can be created even when the participants perform the same or similar actions.

In this paper, we discuss how to prevent users' passwords from being stolen by adversaries. Textual-based password authentication scheme tend to be more vulnerable to attacks such as shoulder surfing. To overcome the vulnerabilities of traditional methods, visual or graphical password schemes have been developed as possible alternative solutions to text-based scheme. But simply adopting graphical password authentication also has some drawbacks; hence some hybrid schemes based on text as well as graphics were developed. We propose a virtual password concept involving a small amount of human computing to secure users' passwords in on-line environments. We also analyze how the proposed scheme defends against phishing, key logger, shoulder-surfing, man in the middle and session hijacking attacks.

Abstract-User authentication through textual passwords is very common in computer systems due to its ease of use. However textual passwords are vulnerable to different kinds of security attacks, such as spyware and dictionary attacks. In order to overcome the deficiencies of textual password scheme, many graphical password schemes have been proposed. The proposed schemes could not fully replace textual passwords, due to usability and security issues. In this paper a text based user authentication scheme is proposed which improves the security of textual password scheme by modifying the password input method and adding a password transformation layer. In the proposed scheme alphanumeric password characters are represented by random decimal numbers which resist online security attacks such as shoulder surfing and key logger attacks. In the registration process password string is converted into a completely new string of symbols or characters before encryption. This strategy improves password security against offline attacks such as brute-force and dictionary attacks. In the proposed scheme passwords consist of alphanumeric characters therefore users are not required to remember any new kind of passwords such as used in graphical authentication. Hence password memorability burden has been minimized. However mean authentication time of the proposed scheme is higher than the textual password scheme due to the security measures taken for the online attacks.
