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 Coinfirm, the first patent addresses techniques for registration of data in a blockchain database and a method for verifying data. Assigned to GE, the second patent addresses techniques for hierarchical data exchange management.
10,944,548, "Method for registration of data in a blockchain database and a method for verifying data," assigned to Coinfirm Blockchain Lab Sp. Zo.o. (PL).
The invention comprises a method for registration of data in a blockchain database, in which database transactions are constructed of standard data containers which may have a fixed size, in a system comprising one or more storage nodes for storing at least part of the blockchain database, one or more approval nodes for approving transactions in said blockchain database and a first computer for generating transactions in said blockchain database, said computer having access to said blockchain database and having access to a first private key. The invention further comprises a method for verifying data based on the aforementioned method for registration and an application of these methods to handle a selected type of document. The invention also comprises a computer program product comprising program code stored on a computer readable medium, said program code comprising computer instructions for performing these methods.
10,938,950, "Hierarchical data exchange management system," assigned to GE.
According to some embodiments, a system to facilitate hierarchical data exchange may include an aggregation platform data store containing electronic records. A data aggregation platform may collect, from a plurality of data source devices, information associated with a plurality of data sources and store the collected information into the aggregation platform data store. The data aggregation platform may also receive a data request from a data consumer device, and, responsive to the received data request, determine a precision tier associated with the data request. The data aggregation platform may then automatically calculate a resource value for the data request based on the precision tier. It may then be arranged for information from the aggregation platform data store to be modified and transmitted to the data consumer device.
