Your earbuds may soon identify you by your heartbeat
Researchers are developing a biometric authentication system called AccLock that uses earbuds to identify users by their heartbeat. This system captures unique heartbeat vibrations through built-in accelerometers, allowing for passive authentication without user interaction. While promising in tests, the technology struggles with accuracy during heavy movement.
- ▪AccLock uses standard earphone hardware to verify a user's identity through heartbeat vibrations.
- ▪The system captures unique patterns from ballistocardiography (BCG) signals inside the ear canal.
- ▪In tests, the system achieved false acceptance and rejection rates of 3.13% and 2.99%, respectively.

Biometric authentication is no longer limited to fingerprints and face unlock. Researchers are now exploring whether your earbuds can recognize you simply by listening to the tiny vibrations created by your heartbeat. A new study published on the arXiv preprint server introduces “AccLock,” a passive authentication system that uses standard earphone hardware to verify a user’s identity. Instead of relying on microphones or voice prompts, the system works through built-in accelerometers already found in many modern earbuds. Your heartbeat may become your next password The technology captures heartbeat-induced vibrations inside the ear canal, known as ballistocardiography (BCG) signals. These signals travel through bones and tissues, creating patterns unique to each person.
