PROTECTING USER IDENTITY BY SHARING A SECRET BETWEEN PERSONAL IOT DEVICES
First Claim
1. A programmable wearable device for use in a body area network, comprising:
- a programmable processor; and
a memory, on which are stored instructions that when executed cause the programmable processor to;
receive a request for a fragmental key;
validate the request;
encrypt the fragmental key with a session key; and
transmit the fragmental key responsive to the request.

Abstract
A wearable device provides protection for personal identity information by fragmenting a key needed to release the personal identity information among members of a body area network of wearable devices. A shared secret algorithm is used to allow unlocking the personal identity information with fragmental keys from less than all of the wearable devices in the body area network. The wearable devices may also provide protection for other personal user data by employing a disconnect and erase protocol that causes wearable devices to drop connections with an external personal data space and erase locally stored personal information if a life pulse from a connectivity root device is not received within a configurable predefined period.
