Researchers have developed a way to use the human heartbeat to replace computer passwords, the latest manifestation of biometrics being used as a security feature.
By replacing digital encryption, the electrocardiogram (ECG) signals of patients' heartbeats could serve as a viable authentication system for access to medical records.
Described in a paper authored by researchers at Binghamton State University, New York, the technology would automatically authenticate access to medical information by matching the patient's heart signals transmitted from a wearable device to those on record.
The system would replace existing encryption schemes for access to medical data requiring more battery power to randomly generate encryption keys for access with wearable devices.
The long-term goal is to provide patients with wearable devices that transmit medical information to doctors in real time while ECG signals would offer a power-saving alternative to computationally intensive encryption keys.
