Smart contracts (blockchains, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Applications. Assigned to Experian, the first patent addresses techniques for symmetric encryption for private smart contracts among multiple parties in a private peer-to-peer network. Assigned to Wells Fargo, the second patent addresses techniques for semantic compliance validation for blockchains.

Abstract
Features for providing a secure method of symmetric encryption for private smart contacts among multiple parties in a private peer-to-peer network. The features include a master key representing a unique blockchain ledger. The master key may be shared among multiple participants in a private peer-to-peer network. Sharing of the master key may include communicating the master key in an encrypted message (e.g., email) using public key infrastructure (PKI). In some implementations, more complex distribution features may be includes such as quantum entanglement. The features support instantiation of a smart contract using a specific master key. The request may be submitted as an entry to the ledger with appropriate metadata and/or payload information for identifying and processing the request.

Abstract
A method may include receiving, at a computing device, an electronic data structure, the electronic data structure including: a location of a validation source for a payload of the data structure; and the payload, wherein the payload identifies a plurality of elements of a transaction; retrieving, from the validation source, a semantic schema; validating the payload of the data structure according to the semantic schema; and based on a result of the validating indicating the payload complies with the semantic schema, appending an electronic compliance signature to the data structure.
