20180337771, "Policy enforcement via peer devices using a blockchain," assigned to IBM.
A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties for ledger verification or information retrieval. One example method of operation may include one or more of receiving an access request from a requesting device for access to an encryption key associated with a user device, broadcasting the request to peer nodes for approval or disapproval, storing a transaction to a blockchain indicating the approval or disapproval of the request for access to the encryption key, and providing access to the encryption key when the approval is indicated.
20180337769, "Blockchain for securing and/or managing IOT network-type infrastructure," assigned to ARM Ltd (UK)
Briefly, example methods, apparatuses, and/or articles of manufacture are disclosed that may be implemented, in whole or in part, using one or more Internet of Things devices to facilitate and/or support one or more operations and/or techniques for a blockchain for securing and/or managing IoT network-type infrastructure, such as implemented in connection with one or more computing and/or communication networks.
