Which biometrics uses heart rhythm for authentication?

• A. Iris Recognition
• B. Butt Biometrics
• C. Heart Rhythm Authentication
• D. Gait Recognition

Answer: (C)

Heart rhythm authentication uses the unique pattern of a person’s heartbeats as the basis for verification. It relies on signals like the ECG waveform or peripheral pulse (PPG) to capture inter-beat timing and waveform features. Those cardiac rhythm characteristics are distinctive enough to enroll as a template and later compare live measurements for identity verification. While heart rhythm can be influenced by activity, stress, or health changes, the underlying pattern can remain consistently specific to an individual, making it a viable biometric modality. This stands in contrast to iris recognition, which analyzes the static patterns in the iris texture, and gait recognition, which looks at how a person walks over time. The option that isn’t a standard biometric approach is not applicable.
