Patent attributes
Systems and methods for performing biometric authentication using a smart ring are disclosed. An exemplary method includes collecting biometric data using sensors of a smart ring while a user is wearing the smart ring, wherein the biometric data includes a heartbeat pattern. The method further includes performing an authentication operation by (i) comparing the collected biometric data to a biometric signature for a known user to determine whether the biometric data matches the biometric signature, and (ii) when the biometric data matches the biometric signature, authenticating the user by updating a record to indicate that the user has been identified and authenticated as the known user. The method also includes, when the record indicates that the user has been identified and authenticated, digitally signing transaction data using a private cryptographic key stored on a memory of the smart ring.
