Biometrics for user identification in mobile health systems

A wearable device, comprising:

• apparatus for securing the wearable device to a user's body;
• a sensor system including one or more biometric sensors, the sensor system being capable of obtaining first biometric data and second biometric data from the user's body, the first biometric data being a first type of biometric data and the second biometric data being a second type of biometric data;
• and
• a control system capable of:
• receiving the first biometric data and the second biometric data from the sensor system;
• performing an authentication process based, at least in part, on the first biometric data and the second biometric data, the authentication process being performed without reference to authentication information from an external device;
• and
• controlling the wearable device according to a result of the authentication process.

A mobile device, comprising:

• a biometric sensor system;
• a wireless interface system;
• and
• a control system capable of:
• receiving first biometric authentication information via the wireless interface system, the first biometric authentication information corresponding to first biometric data obtained from a user who is currently using a wearable device;
• obtaining second biometric data via the biometric sensor system;
• determining second biometric information from the second biometric data;
• determining whether the current user is an authorized user by comparing the second biometric information with stored biometric information;
• and
• associating the stored biometric information with the first biometric information if the control system determines that the current user is the authorized user.

A method, comprising:

• obtaining, via a sensor system of a wearable device, first biometric data from a user who is currently using the wearable device;
• determining first biometric authentication information based on the first biometric data;
• providing, via an interface system, the first biometric authentication information to a second device;
• receiving, via the interface system, a signal from the second device;
• and
• controlling the wearable device according to the signal.
