摘要: AbstractThis paper presents a method for freely drawing graphical password. The new achieves better security than conventional textual passwords and other password schemes. With this it is also easier user to remember the basic idea of use number user’s representative sample drawings predict future prediction interval. predicted values are obtained by conducting least squares polynomial regression/B-spline regression model. Based on deviation drawings, interval signature/picture generated. This used as and, subsequently, if drawn lies within interval, authenticated into application.
