摘要： A device and a method for graphical passwords. A device displays an initial image comprising a plurality of graphical elements, each graphical element having at least two variants; receives user input to select a variant of a number of the graphical elements, thereby generating a modified image; and generates the secret value from at least the selected variants of the graphical elements. The graphical elements are advantageously seamlessly integrated in the images, thereby making the system resistant to shoulder surfing attacks.

摘要翻译： 图形密码的设备和方法。 设备显示包括多个图形元素的初始图像，每个图形元素具有至少两个变体; 接收用户输入以选择多个图形元素的变体，从而生成修改图像; 并且从图形元素的至少所选变体生成秘密值。 图形元素有利地无缝地集成在图像中，从而使系统抵抗冲击冲击。
