Managing digital rights for encrypted content assets
The patent US12074984B2 outlines a method and system for managing access to encrypted content assets through a distributed ledger, such as a blockchain. The core of the invention involves generating a transaction that includes an identifier and a decryption key, which allows authorized user devices to access specific portions of the encrypted content. The transaction is stored in a distributed ledger, making it accessible based on the identifier. The method also includes provisions for controlling the timing of access to the content, which can be influenced by various factors such as fee values or time values associated with the transaction. Additionally, the system allows for the possibility of user devices accessing portions of the content before receiving the identifier.
Further enhancements to the system include the ability to track access counts of the encrypted content, which can be compared to historical data to provide proof of distribution. The architecture supports user devices accessing the content via a network and a content server, ensuring a streamlined process for content retrieval. The patent also encompasses non-transitory computer-readable media that store executable instructions for implementing the described methods. Overall, the claims emphasize a secure and efficient framework for managing encrypted content access, leveraging the benefits of distributed ledger technology.
