When using an established pattern of finger movements to unlock a phone or other touch sensitive device a wear pattern is left on the screen. This wear pattern can be analysed to disclose the security pattern. When using a computing device (phone, tables, laptop) in a shared environment it is often difficult to hide or obscure your password from 3rd party observation. This method makes the observation and recording of the authentication sequence more difficult and does not leave traces that can be analysed as the connect-the-dots pattern on phones can.

Method and Apparatus to use image selection for authentication

A set of wheel displays similar to the wheels in a slot machine are displayed on the screen. The wheels are initialised to a random state. The user moves the wheels up or down until a predetermined pattern is achieved and the phone is unlocked. Setup:

    User selects a number of images and/or preloaded icons to be presented as part of the authentication. Any user provided images are resized to match the sizing of the preloaded icons. The set of resized images and preloaded icons will be referred to as the icons in the rest of this document.

    The user then selects a subset of the icons and orders them. Icons may be used more than once. The order of the selected icons is recorded in the device. Usage:

When the device is "locked" and authentication is required.

A number of "wheels" are displayed to the user. The wheels appear like the

wheels on a slot machine with a central line for alignment and displaying icons

above, on and below the line. The number of wheels displayed is dependent upon the screen size of the device as well as the number of icons the user selected in the subset defined during setup.

    The user manipulates the wheels until the icons are aligned, in order, on the screen. If there are more icons than currently displayed wheels subsequent screens are produced to until all icons have been selected as shown in the illustrations below.


The implementation consists of a touch screen device, a computing device

with both permanent storage and working memory.

    Images of the available icons are placed in permanent s...
