How to Block DRM License Requests for a Specific User

Question
How do I block a specific user from requesting a DRM license?
 

Answer & Resolution
To block a specific user from requesting a DRM license, you can add the user’s user_id or device_id to the DoveRunner DRM blacklist in the Multi-DRM service. You can manage the blacklist through the DoveRunner Console under Multi-DRM → Blacklist Management (User Blacklist / Device Blacklist) or by using the Blacklist API.

Once a user_id or device_id is added to the blacklist, DoveRunner checks the list for every incoming DRM license request. If the request matches a blacklisted identifier, the license is immediately denied and the user is unable to decrypt or play DRM-protected content, even if they still have a valid playback link or application access.

This feature is commonly used to stop access for users involved in suspicious activity, policy violations, or confirmed misuse of content. The restriction is enforced in real time and applies to all future license requests associated with that user_id or device_id. If needed, the user can be unblocked later by removing the corresponding identifier from the blacklist, after which DRM license issuance will resume normally.
