Abstract
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.
