Graphical password: Experimental comparing and field study

The most common computer security authentication is recall-based authentication.Users want passwords to be easy to remember, however this preference causes thatselected passwords can be easily guessed by others. To address this problem, someresearchers have developed authentication methods that use pictures as passwords,because of the human ability to accurately recognize and recall images.In this thesis, we will discuss our study results to compare the usability and securityof recognition-based graphical password techniques. Moreover, we conducted fieldstudy of graphical password application to examine usability. The results of fieldstudy will be shared.Keywords: Graphical Password, Authentication, Usability, Field Study
