Keyboard dynamics refers to a biometric security method that evaluates the unique patterns of an individual's typing behavior. This encompasses factors such as how hard the keys are pressed and the rhythm of keystrokes. Each person has a distinctive typing style characterized by the timing of when keys are pressed and released, along with the pressure applied to keys. These characteristics create a behavioral profile that can be used to authenticate users based on their typing habits.

This method is advantageous because it does not require additional hardware, like fingerprint readers or cameras, and can be implemented in a variety of environments where typing occurs. It is particularly effective in scenarios where users are interacting with devices that do not have security measures in place, allowing for continuous authentication as they type.

The other options relate to different biometric characteristics but do not pertain to keyboard dynamics. For instance, voice patterns evaluate vocal traits, hand dimensions assess physical attributes, and eye movements involve monitoring gaze behaviors. Each of these aspects represents a distinct biometric modality, whereas keyboard dynamics is specifically focused on evaluating typing characteristics.
