Touch pad Authentication

    This publication proposes a mechanism which allows a user to define a simple but unique pattern/drawing/gesture that can traced on a touchpad device as a substitution for traditional password authentication.

Samples of possible gestures are as follows:

1.

2.

3.

4.

    Currently simple mouse gestures can be recognized by the Opera browser, games, and other tools to automate tasks. This is another application for the same technology with the touch pad allowing for gestures with greater complexity e.g. gesture with discontinuity listed in figures 3 and 4.

    Dynamic metrics (e.g. speed and pressure) could also be used as part of the authentication process. An extension to this method is to use a standard mouse or other pointing device.

Use Case 1:

1. User powers on the computer
2. Computer boots to log in prompt
3. User draws personal gestures on the touch pad
4. Computer unlocks and continues to boot to show the desktop Use Case 2:
1. User does not use the computer for a while
2. The computer screen is locked
3. User draws personal gestures on the touch pad
4. Computer unlocks and shows the desktop
