Abstract
Alphanumeric username and password There are significant drawbacks in this method. For example, users can not choose passwords that can easily be guessed. On the other hand, if a password is difficult to guess, it is often difficult to remember that to solve this problem, some researchers have developed authentication methods that use pictures as a password. Graphical password schemes have been proposed as a possible alternative to text-based schemes, partly inspired by the fact that humans can remember better pictures than pictures; Psychological studies support such assumptions that the painting is easy, and if you want to be able to do so, you will not be able to read them. Due to these advantages, there is growing interest in graphical passwords. In addition to workstation and web log-in applications, graphical passwords have also been applied to ATM machines and mobile devices.
