Disclosed herein are embodiments for implementing periodic management of cryptographic keys. An embodiment includes a processor configured to perform operations comprising receive a first input associating a first set of subscribers with a first data stream published by the first publisher device, and a first cryptographic key. Processor may transmit, to the first publisher device, a first confirmation, indicating that the first cryptographic key is ready for use, for example. In some embodiments, processor may release the first cryptographic key to a first set of subscribers, receive a second input from a publishing user, associating a different, second set of subscribers with the first data stream, and receive a second cryptographic key after a certain time period. Processor may further transmit, to the first device, a second confirmation, indicating that the second cryptographic key is ready for use, and release the second cryptographic key to the second set of subscribers.

Aspects of the subject disclosure may include, for example, a device that has a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations including: receiving media content from user equipment, wherein the media content comprises a sample of an existing work used to modify an original work; analyzing the media content using machine learning to determine a plurality of composition parameters that characterize aspects of the media content; recording the plurality of composition parameters determined, including an identification of composition parameters in the plurality of composition parameters attributable to the existing work, and an identification of composition parameters attributable to the original work, in a blockchain ledger; searching for the composition parameters in the blockchain ledger for one or more works having similar composition parameters; and reporting any works found during the searching to the user equipment.
