Abstract
Disclosed are examples of decentralized systems and related apparatus, devices, computer program products, and methods for secure access of digital content. In some implementations, a first request from a client to access encrypted digital content includes a call on a digital contract. The call passes an ephemeral key set encrypted with a public key of a consumer. A transaction identifying the first request in association with the encrypted ephemeral key set is recorded in the digital contract. The transaction is identified by a transaction identifier (ID), which is sent to the client. A second request from the client includes: an authorization token including the transaction ID, and a signature of the consumer. Authorization of the consumer is verified based on the authorization token. A transaction identifying one or more keys is recorded in the digital contract. The digital content can be re-encrypted and sent to the client.
