Abstract:

User behaviour, their selection pattern, and the appropriate time they give in password creation are highly influential in information security. For passwords to be easily recalled, amenity and security should be assured. Existing schemes do not evaluate the list of leaked or exposed passwords; thus, they result in vulnerability towards attacks like a dictionary, shoulder surfing, and many more. Graphical passwords additionally face a problem called unmanaged password space. The password space of the image depends on the type of image selected or uploaded as a password. Thus, understanding the behaviour of users keeping passwords is essential and the need of the hour, as the space needs to be understood, managed and correlated. This paper extends our previous work, where we proposed a technique Character Set and Direction technique (CSD) and developed an android application on it. This paper understands various Graphical Password schemes as per their configured password space. It compares them based on password space, several re-tries during login, ease to remember, recall and use. The paper also calculated the entropy password space and the number of re-tries by users for password login time using the proposed Character Set and Direction technique.
