Now-a-days, graphical password is being regarded as a promising alternative in network security to replace traditional text-based password in which users interact with images for authentication rather than input alphanumeric stings. Traditionally researchers develop a Click-Draw based Graphical Password Scheme (CD-GPS) with the purpose of improving the image-based authentication in both security and usability by combining the above three techniques. An initial user study which shows positive results that the authors' scheme is good at both security and usability, and subsequently give a preliminary security analysis of their scheme against several well-known attacks (e.g., dictionary attack).
