  • Patent number: 11496450
    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.

  • Patent number: 11496440
    Abstract: Mechanisms for split tunneling are provided. The mechanisms identify user devices and determine that communications for a first device of the user devices are to be tunneled. These mechanisms also receive a DNS request from a second device of the user devices, modify the DNS request to request meta information corresponding to a domain identified in the DNS request, and send the DNS request to a DNS server. The mechanisms further receive a response to the DNS request, wherein the response includes the meta information, determine that communications for the second device are not to be tunneled based at least in part on the meta information, and cause the communications for the first device to be tunneled and the communications for the second device to not be tunneled.
