Image Selection for Graphical Password Authentication
摘要
One of the most crucial elements of information security is user authentication. User authentication is the primary strategy for ensuring the utmost factors for computer security. It gives the base for access control and user liability. Over time, among numerous types of user authentication systems, alphanumeric passwords have remained the most common. A graphical password is a type of authentication system that relies on the user’s selection of images presented in a graphical user interface (GUI), in a specific order. This approach, known as graphical user authentication (GUA), differs from the traditional system of using alphanumeric usernames and passwords, which is presently the most common way of authenticating computer users. This system has been shown to have significant disadvantages. For example, users tend to choose passwords that can be fluently guessed. On the other hand, if a password is delicate to guess, then it is frequently difficult to remember. To overcome this problem of low security, authentication styles are developed by experimenters, using images as a password. This explorative paper is a detailed examination of current graphical passwords, proposing a new proposition. Graphical passwords have been proposed as a volition to textbook-grounded schemes, based on the idea that humans tend to remember pictures more fluently than text. Also, pictures are considered to be more user-friendly.
