11,165,567, "Permission information management system, and permission information management method," assigned to NTT (JP).
A user terminal generates a first key pair and a second key pair, transmits a permission request including a public encryption key of the second key pair after electronically signing the permission request with a secret encryption key, and acquires, from permission information transmitted from a right-holder terminal, a content decryption key by using a secret decryption key of the second key pair and uses the content. The right-holder terminal stores a third key pair and the content decryption key, verifies the permission request received, and encrypts the content decryption key by using the public encryption key of the second key pair included in the permission request and transmits the permission information including the encrypted content decryption key after electronically signing the permission information with a secret encryption key of the third key pair. The permission request and the permission information are transmitted and received via a blockchain.
11,151,665, "Systems and methods for participative support of content-providing users," assigned to Heir Apparent, Inc.
Systems and methods for facilitating participative support among users are disclosed. The users may include content-providing users that provide user-provided content to other users. Exemplary implementations may: obtain items of user-provided content; effectuate presentations of the items of user-provided content through user interfaces to the users; receive revenue information from the users, wherein the revenue information represents received revenue for the content-providing users, including a participative-support exchange between a second user and the content-providing user of an amount of a currency being exchanged for a portion of particular (future) revenue received by the content-providing user; determine the particular revenue for the content-providing user, based on the received revenue information; determine and distribute the portion of the particular revenue to the second user, in accordance with the participative-support exchange.
