Abstract

A graphical password arrangement displays a predetermined graphical image and requires a user to "touch" predetermined areas of the image in a predetermined sequence, as a means of entering a password. The password is set by allowing the arrangement to display the predetermined areas, or "tap regions", to a user, and requiring the user to position these tap regions in a location and sequence within the graphical image, with which the user desires the password to be set at. These "tap regions" are then removed from the display, leaving the original image by itself. The arrangement then waits for an entry device (user) to select the "tap regions", as described above, for possible access to a protected resource.
