Private data processing

Abstract:

A method includes storing, in one or more databases amongst a plurality of databases by one or more nodes in a distributed database system, data for one or more of network-enabled devices. The data for each network-enabled device includes encrypted private data, and metadata associated with the private data. The metadata may include permissions data, time period validation data, and encryption parameters. In addition, the method may include locating the encrypted first private data and determining using first permissions data associated with the encrypted first private data and using the second network-enabled device identifier if the second network-enabled device is authorized to access the first private data. The method includes providing the first private data to the second network-enabled device. The second network-enabled device obtains and decrypts the encrypted first private data to obtain the first private data.
