ChoCD: Usable and Secure Graphical Password Authentication Scheme


  • Faculty of Science and Technology, Universiti Sains Islam Malaysia (USIM), Nilai - 71800, Negeri Sembilan, Malaysia


Since designing effective graphical password authentication schemes is of vital important, this paper attempts to address the need by providing a new way for designing and developing hybrid graphical scheme named ChoCD. ChoCD combines the method of "Click-based”, “Choice-based”, and “Draw-based”. By combining these, it is anticipated that it will offer better usability and security. An evaluation towards ChoCD was conducted to measure its viability and practicality as the alternative user authentication. From these conduct of evaluations, it was found that ChoCD is easy to use and provides more security than other existing schemes and thus potentially be used for user authentication.
