Keystroke dynamics recognition definition

From Antispoofing Wiki

Keystroke dynamics recognition can identify a person by the way they type on a keyboard.

Keystroke dynamics recognition (KDR) is a biometric modality that focuses on analyzing an individual’s manner of keyboard typing. The way a person types on a computer keyboard proves to be unique in terms of speed, pauses, mistypes and errors, used key combinations, and so on.

Identification, verification and matching are possible due to a biometric template that is created when a user types in the random words/symbols prompted by the system. However, it is assumed that KDR may be prone to misidentification due to behavioral instability: keyboard typing can improve with practice or decline due to tiredness.
