A Comparison between Position-Based and Image-Based Multi-Layer GUAS

Abstract

System security is very important, especially in the age that we live in. One of the ways to secure data is by creating a password that makes it difficult for unauthorized user to gain access to the system. However, what makes it difficult for the system to be attacked is directly dependent on approach used to create it and how secured it is. Text based approach is the oldest authentication approach. It calls for that the user provides textual password as a way to benefit get right of entry to the system. But, this technique has shown a considerable disadvantage and several vulnerabilities, certainly one of which is the difficulty in recalling or remembering textual passwords. Numerous different attacks that textual passwords are susceptible to encompass brute force attack, dictionary attack, and shoulder spying and so on. The introduction of graphical schemes made things a lot better. Graphical passwords make use of images. However, most graphical schemes are vulnerable to shoulder surfing attacks. For the purpose of this research work, two systems were developed; An Image-Based multi-layer graphical user authentication system and a Position-Based multi-layer graphical user authentication system. The reason behind this research work is to compare the two systems, and evaluate them based on three major performance metrics: (1) Security, (2) Reliability (3) Individual preference.
