Taliware recently launched a software development toolkit to enable a smartwatch wearer’s ECG biometric information to verify their identity without a password.

Biombeat, Taliware’s ECG-based biometric verification application, uses a set of algorithms for human identity verification that apply machine-learning techniques to decipher a person’s electrocardiogram. The application is compatible with the Apple Watch models that are equipped with an ECG sensor. Taliware also plans to extend its  platform to include Google Verily, Samsung and Withings.

When used with a smartphone, Biombeat can allow a mobile application to authenticate, or log in, using a user’s ECG trace, verify the user’s proximity to the phone and determine the geographical location of the user and the app for a multifactor authentication method.

“With Taliware and an ECG-enabled smartwatch, your heartbeat is your password,” founder and CEO Tarik Tali said in a news release. “Moreover, our geolocation component adds another layer of security to counter fraud, providing proof of presence while ensuring that a person is who they say they are, along with a time-stamped location.”

Taliware’s ECG authentication is designed to continually assess an individual cardiac rhythm as a unique and persistent biometric. It addresses numerous security challenges, according to the company, including eliminating password friction, reducing fraud costs and support calls and the costs associated with point-of-sale card cancellations and replacement card issuance.
