    • PROBLEM TO BE SOLVED: To provide a secure access method which enables easily remembered and intuitive passcodes and personal identifiers.SOLUTION: Graphical passcodes are determined by touches and movements on a touch sensitive surface. The graphical passcodes comprise various combinations of swipes, taps or drags on a touchscreen surface as defined by a user. A user's selected graphical passcode is stored in a memory for comparison to subsequent entries of the graphical passcode in order to authenticate the user. An envelope may be generated to define a range of acceptable pressure, speed, coordinate positions or other parameters, as a function of time or position, required for passcode authentication. The envelope may be stored in a computer memory and is used to authenticate a user by determining whether an entered graphical passcode falls within the envelope.
    • 要解决的问题:提供一种安全访问方法,可以轻松记忆和直观的密码和个人标识符。解决方案:图形密码由触摸敏感表面上的触摸和移动确定。 图形密码码包括用户定义的触摸屏表面上的滑动,抽头或拖动的各种组合。 将用户选择的图形密码存储在存储器中以与图形密码的后续条目进行比较,以便认证用户。 可以生成信封以根据密码认证所需的时间或位置的函数定义可接受的压力,速度,坐标位置或其他参数的范围。 信封可以存储在计算机存储器中,并且用于通过确定输入的图形密码是否落入信封内来认证用户。
