Abstract: Methods and systems for secure, encrypted and distributed ownership and usage of big data are provided. According to one example, a server maintains a local key management data store, a data blockchain copy, an audit blockchain copy, and a metadata blockchain copy. A data operation from a user electronic device is received. The server verifies that the user electronic device has access against the local key management data store, runs the data operation and records metadata about the data operation, and writes data blocks to the data blockchain copy, the audit blockchain copy, and the metadata blockchain copy. The server broadcasts the updated blockchain copies to the peer-to-peer network for replication.

Abstract: An ecosystem that allows fine-grained multi-party control over access to information stored in one or more data sources of a data provider. A requesting party can submit a query job to the data provider. Resellers in the chain can introduce their own query modifiers to the query job, adding additional data access, data transformation and segmentation functions to the query job. The data provider can append its own query modifier to the query job and execute the query job with all of the query modifiers. Access control for each link in the chain is checked before the query modifier for the link is executed. After execution of all query modifiers and the query job, the results can be provided to the requesting party.

Abstract: Methods and systems for controlled data sharing are provided. According to one example, a data provider defines one or more data policies and allows access to data to one or more data consumers. Each data consumer submits analytics tasks (jobs) that include two phases: data transformation and data mining. The data provider verifies that data is trans-formed (e.g., anonymized) according to the data policies. Upon verification, the data consumer is provided with access to the results of the data mining phase. An ecosystem of data providers and data consumers can be loosely coupled through the use of web services that permit discovery and sharing in a flexible, secure environment.
