摘要: In ubiquitous textual password schemes, users choose passwords that contain predictable characteristics are roughly equated with what flnd easy to recall. This motivates us examine user choice in graphical determine whether exist may reduce the entropy of space. We present an informal study scheme proposed by Jermyn et al. (1999), and results, both context study’s goals a separate analysis results performed at later date. Our support drawings relating symmetry, number composite strokes, centering within grid. also highlight usability challenge DAS scheme.
