1. A method performed by a smart ring, the method comprising:
collecting, by one or more sensors of the smart ring, a heartbeat pattern of a user while the user is wearing the smart ring;
collecting, by the one or more sensors of the smart ring, acceleration data corresponding to a walking gait of the user;
collecting, by the one or more sensors of the smart ring, gestural data corresponding to a gesture of the user;
performing, by one or more processors of the smart ring, an authentication operation by:
analyzing the heartbeat pattern, the acceleration data, and the gestural data;
comparing the heartbeat pattern to a first biometric signature for a known user to determine whether the heartbeat pattern matches the first biometric signature;
comparing the acceleration data to a second biometric signature associated with a walking gait pattern of the known user to determine whether the acceleration data matches the second biometric signature;
comparing the gestural data to a third biometric signature for the known user to determine whether the gestural data matches the third biometric signature;
when the heartbeat pattern matches the first biometric signature, the acceleration data matches the second biometric signature, and the gestural data matches the third biometric signature, authenticating the user as the known user by updating a record;
providing a private cryptographic key for the known user in response to authenticating the known user, wherein the private cryptographic key is associated with a seed value or phrase stored in a profile of the known user;
digitally signing a transaction data using the private cryptographic key; and
storing the private cryptographic key on a memory of the smart ring.
