System and method for preventing unauthorized use of digital media

A system for protecting digital media content from unauthorized use on a client, comprising:

• a processor for executing computer program instructions;
• and
• a non-transitory computer readable medium storing computer program instructions executable to perform steps comprising:
• receiving, by the client from a server, a blacklist identifying a plurality of piracy threatening items that pose a piracy threat such that, if installed and active with playback of the digital media content on the client, the piracy threatening items facilitate unauthorized use of the digital media content, the piracy threatening items on the blacklist having associated priority values;
• identifying a first subset of piracy threatening items in the blacklist and a second subset of piracy threatening items in the blacklist responsive to the associated priority values, wherein the first subset of piracy threatening items have higher priority values than the second subset of piracy threatening items;
• determining whether one or more piracy threatening items associated with the first subset are present on the client;
• performing a digital rights management (DRM) transaction provisioning the digital media content for playback, on the client, responsive to determining that no piracy threatening items associated with the first subset are present on the client;
• responsive to performance of the DRM transaction, determining whether one or more piracy threatening items associated with the second subset are present on the client;
• and
• playing back the digital media content on the client responsive to determining that no privacy threatening item associated with the second subset are present on the client.
