Abstract: A system architecture and methods to enable a user (data provider) to selectively release some or all personal data to third parties (data consumers) who may then benefit from direct, precise, and permissioned audience data. The solution disclosed herein provides an open and transparent exchange (using a blockchain or other distributed ledger technology) whereby third parties can request permission to a user’s data and know they have received and continue to receive the user’s explicit permission (managed in a smart contract) to use the data. Users are provided a web portal or app interface where they can manage all of their issued permissions with all third parties across their devices and touch points with third parties. Users can update their data (e.g., address, email, or zip code) and know that permissioned third parties will always be updated.

Abstract: Distributed Permissioned Data (DPD) network to securely store encrypted data by distributing multiple copies of data fragments in resilient nodes in the network. Data fragments are stored in multiple node chains in the network. Storing data in this distributed fashion offsets conditions where some nodes are not available because they are offline or unreachable. Nodes may also have other constraints placed on them, such as bandwidth utilization, storage limits, and CPU allocation. Multiple versions (replicas) of the data fragments are stored in multiple nodes to provide resiliency. By properly selecting a number of data fragments and a number of replicas, data stored in the network will be highly available.
