1. A method for authorizing a target device to access multimedia content comprising:
receiving, from the target device, a request to access the multimedia content, wherein the request to access the multimedia content is recorded on a blockchain;
identifying a first hash value associated with the target device;
comparing the first hash value to a second hash value in an allocation table, wherein the allocation table is stored on the blockchain and wherein the second hash value is associated with the target device;
if the first hash value and the second hash value in the allocation table are the same, comparing the multimedia content to a multimedia content value in the allocation table, wherein the multimedia content value in the allocation table is associated with the second hash value;
based on the comparison of the multimedia content to the multimedia content value in the allocation table, determining whether the target device has permission to access the multimedia content;
in response to the target device not having permission to access the multimedia content, reporting the first hash value associated with the target device to at least one media content provider; and
in response to the target device having permission to access the multimedia content, verifying the request from the target device to access the multimedia content.
