VALIDATION OF BIOMETRIC IDENTIFICATION USED TO AUTHENTICATE IDENTITY OF A USER OF WEARABLE SENSORS
First Claim
1. An apparatus comprising:
- a wearable housing configured to couple to a portion of a limb at its distal end;
a subset of physiological sensors configured to provide data representing physiological characteristics;
a subset of motion sensors configured to provide data representing motion characteristics; and
a processor configured to execute instructions to implement a biometric identification generator configured to generate a biometric identifier, and to implement a biometric validator configured to;
receive data representing a physiological characteristic from a physiological sensor;
determine whether the wearable housing is adjacent to the portion of the limb based on the physiological characteristic;
detect a value of the physiological characteristic is in a first range of values of the physiological characteristic specifying the wearable housing is in a not-worn state;
invalidate the biometric identifier responsive to the value in the first range of values; and
block accessibility of the biometric identifier.

Abstract
Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and wearable computing devices for facilitating health and wellness-related information, and more particularly, to an apparatus or method for using a wearable device (or carried device) having sensors to identify a wearer and/or generate a biometric identifier for security and authentication purposes (e.g., using the generated biometric identifier similar to a passcode). In some embodiments, a biometric validator is included to validate the accuracy of the biometric identifier to authenticate the identity of the user. The biometric validator can determine conditions in which the biometric identifier is invalid (e.g., when a wearable device is no longer worn by a user).
