New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue the theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Alibaba, the first patent addresses techniques for asymmetric key management in consortium blockchain networks. Assigned to IBM, the second patent addresses techniques for socially enabled consensus blockchain summarization.
10,785,018, "Asymmetric key management in consortium blockchain networks," assigned to Alibaba (CN)
Implementations of the present specification provide for management of service keys for consortium blockchain networks within a blockchain-as-a-service (BaaS) platform. Implementations include actions of receiving a request for a service key from a participant in a consortium blockchain network provisioned within the BaaS platform, determining that the participant is authorized for the service key based on a service authorization table that records participant privileges within the consortium blockchain network, providing a key package including an encrypted private key of the service key, and a public key of the service key, and sending the key package to the participant, the participant decrypting the private key of the service key using a public key associated with the participant.
10,785,045, "Socially enabled consensus blockchain summarization," assigned to IBM.
A method includes establishing parameters and objectives for a digital communication session (DCS) regarding a topic, where computing devices are targeted to participate in the DCS. The method further includes determining whether a blockchain exists for the topic and, if so, affiliating the DCS with the blockchain. The method further includes obtaining data pertaining to the DCS from one or more of the computing devices. The method further includes generating a summarization of the DCS based on the data and in accordance with the parameters and objectives. The method further includes sending a request to at least some of the computing devices to validate the summarization. When a desired number of the at least some of the computing devices have validated the summarization, a data block regarding the DCS and the summarization is generated and the blockchain is updated to include the data block.
