New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue our theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to SmartAxiom, the first patent addresses techniques for enabling IOT security using a decentralized IOT security platform that leverages the advanced communication and blockchain security thread model to protect IOT eco-systems. Assigned to Whoborn (KR), the second patent addresses techniques for a content right management method that includes receiving contents from a user, and generating a create key for a right for the contents by encrypting the contents using encryption information, in which the create key includes a copyright of the contents and a creation right of the contents.

Abstract
The present disclosure relates to a method and system for enabling IOT security using a decentralized IOT security platform that leverages the advanced communication and blockchain security thread model to protect IOT eco-systems. The platform uses a multi-chain data schema including a device chain and an event chain. The multi-chain data schema uses a time-envelope mechanism to generate an event to connect different device chains and enforce a set of security rules through smart contracts. The method comprising receiving an encrypted block from IOT device with event data and verifying the device signature and identity based on certain rules within the device chain. Further, the method comprising determining access to event chain using previous token, current token and timestamp of the encrypted block and updating the event chain upon access determination. The event chain protects data integrity and confidentiality against malicious packets, unauthorized devices, weak encryption and man-in-the-middle attacks.

Abstract
A platform and method for content management is disclosed. A content right management method includes receiving contents from a user, and generating a create key for a right for the contents by encrypting the contents using encryption information, in which the create key includes a copyright of the contents and a creation right of the contents.
