System and method for continuous user identification via piezo haptic keyboard and touchpad dynamics

A method of user identification based on piezo haptic keyboard and touchpad operation dynamics comprising:

• detecting, via a piezo haptic keyboard controller operably connected to a plurality of piezo electric elements situated beneath a plurality of keys of a piezo haptic keyboard and beneath a touchpad, a recorded haptic hardware typing or touch behavior parameter value describing interaction between a user and a piezo haptic keyboard or a touchpad;
• determining, via a processor, that the recorded haptic hardware typing or touch behavior parameter value differs by a preset threshold percentage from a preset haptic hardware typing or touch behavior parameter value within an authenticated user personal typing profile associated with an authenticated user;
• wherein the authenticated user personal typing profile includes an initial repeated pattern of an initial set of values for a combination of a plurality of initial haptic hardware typing or touch behavior parameters identified by the processor, via machine learning;
• and
• denying the user access to the information handling system.

A piezo haptic keyboard and touchpad user identification system of an information handling system comprising:

• a processor receiving an authenticating user input identifying an authorized user of the information handling system;
• a piezo haptic keyboard controller operably connected to a plurality of piezo electric elements situated beneath a plurality of keys of the piezo haptic keyboard and beneath a touchpad;
• the piezo haptic keyboard controller detecting initial haptic hardware typing or touch behavior parameters describing characteristics of a plurality of deformations of the plurality of piezo electric elements during an initial period of interaction between the authorized user and the piezo haptic keyboard and the touchpad;
• the processor executing machine readable code instructions to:
• identify, via machine learning, an initial repeated pattern of an initial set of values for a combination of a plurality of the initial haptic hardware typing or touch behavior parameters reoccurring during the initial period of interaction between the authorized user and the piezo haptic keyboard and the touchpad;
• associate the initial repeated pattern with the authorized user in an authenticated user personal typing profile;
• the piezo haptic keyboard controller detecting an updated haptic hardware typing or touch behavior parameter value during a later period of interaction between the authorized user and the piezo haptic keyboard and the touchpad;
• the processor determining the updated haptic hardware typing or touch behavior parameter value differs from a value for a corresponding initial haptic hardware typing or touch behavior parameter in the initial repeated pattern by a preset threshold percentage;
• and
• the processor denying access to the information handling system.
