Researchers are devising a way to protect electronic health records by using the patient’s heartbeat as a password . Zhanpeng Jin, an assistant professor in the school of engineering and applied science at Binghamton University, believes the method could enhance security and privacy while minimizing cost.
The system builds from Jin’s previous studies of using a brain print to access computers. Hospitals often take electrocardiograph (ECG) readings for diagnosis using a biosensor attached to the skin. Jin believes this data could be used as a password to unlock encrypted health information.
There are some caveats facing the system. Age, illness, and injury can change a person’s ECG, which could cause authentication issues. Jin and his team are working out ways to incorporate these variables in their work.
