Final answer:
Dynamic biometrics refers to the measurement of unique behavioral characteristics used for recognition purposes. Examples include voice patterns, handwriting characteristics, and typing rhythm. Thus, correct answer is C.
Step-by-step explanation:
Recognition by voice pattern, handwriting characteristics, and typing rhythm are examples of dynamic biometrics. Dynamic biometrics refer to the recognition of individuals based on behavioral traits that are typically performed over a period of time and may change in different contexts. Unlike static biometrics, which involve unchanging physical characteristics like fingerprints or iris patterns, dynamic biometrics depend on the way an individual behaves or performs certain actions.
Voice pattern recognition analyzes how someone speaks, handwriting recognition examines how a person writes, including the pressure applied and the rhythm, and typing rhythm captures the unique time intervals between key presses when typing on a keyboard.
