New pending patent applications are published by the USPTO on Thursdays. This week's Spotlight Applications continue the theme of blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. Assigned to Zensar (IN), the first application discloses techniques for evaluating the feasibility of introducing a new node in a blockchain infrastructure. Assigned to Walmart, the second application discloses techniques for managing distributed content using layered permissions.
20180219945, "System and method for evaluating the feasibility of introducing a new node in a blockchain infrastructure, assigned to ZenSar Technologies (IN).
The present disclosure envisages a system for evaluating the feasibility of introducing a new node in a blockchain infrastructure. The blockchain dimension queries and the transaction dimension queries are presented to a user. The user provides responses to the blockchain dimension queries and transaction dimension queries. A feature detector module detects features from the blockchain dimension responses and the transaction dimension responses. A feature value assignor assigns feature values to the detected features. A criticality assignor assigns criticality scores to the detected features. A weightage assignor assigns weightage scores to the blockchain dimension queries and the transaction dimension queries. The feasibility evaluator receives the feature values, the criticality scores, and the weightage scores, and calculates a feasibility score, thereby evaluating the feasibility of introducing the new node.
20180218364, "Managing distributed content using layered permissions," assigned to Walmart Apollo, LLC.
Examples of the disclosure provide systems and methods for managing distributed content. A computing system constructs a permission list including a first layer defining first privileges and a second layer defining second privileges. The permission list is associated with a first transaction regarding the distributed content between a first user and a second user such that the first layer is associated with the first user and the second layer is associated with the second user. A request associated with the first transaction is transmitted to a network including one or more nodes, and a notification associated with a validation of the first transaction is received from the network. If a parameter is satisfied, a trigger is executed to modify the second layer. A notification associated with a validation of a second transaction regarding the distributed content between the first user and the second user is received.
