Heartbeat accuracy for biometric verification shows promise and limitations

A recent study published in Scientific Reports examines a new method of biometric verification called CompaRR, that records beat-to-beat information embedded in intervals between heartbeats.

While many forms of biometric verification involve stationary physiological signals like facial authentication and fingerprint scanning, non-stationary signals like heartbeats are more difficult to fake.

While ECG (or “EKG”) recordings have shown the capacity to verify identity through the heart's electrical activity, the method uses a complex system that usually requires a medical professional to …
