Disc Player Authentication Server for Secure Media Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media content distribution technologies lack effective security measures to prevent unauthorized use and distribution, particularly for high-value content like pre-release screeners, where traditional methods may not provide sufficient protection against piracy and unauthorized access.
Innovation Solution
A method and apparatus that control media content distribution by sending authentication instructions from a server to a disc player, where the disc contains media content without required playback files, which are only downloaded and made playable after successful authentication, using a database to validate discs and users, and employing digital rights management and copy protection mechanisms to ensure secure playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional distribution methods are used to distribute media content on discs, then ease of distribution is improved, but security against unauthorized use and piracy deteriorates
Solution Approach 1:
The media content distribution system is segmented into multiple components: the disc containing media content, a separate authentication mechanism, and a file delivery system. The disc is divided into portions, with some files required for playback kept separate from the media content itself, creating a multi-component system that requires authentication to assemble fully.
Solution Approach 2:
An authentication server acts as an intermediary between the disc and the playback system. This intermediary verifies disc validity and user authorization before releasing the playback files, creating a controlled distribution channel that prevents unauthorized access while maintaining ease of legitimate distribution.
2Reliability
If authentication mechanisms are added to prevent unauthorized access, then security is improved, but device complexity deteriorates
Solution Approach 1:
The disc player automatically performs authentication by sending disc information to the authentication server and automatically receiving and installing playback files when authorization is confirmed. This self-service approach minimizes user interaction with complex authentication processes while maintaining strong security.
Solution Approach 2:
Authentication and file delivery are performed in advance before playback begins. The system pre-verifies disc validity, pre-authenticates user authorization, and pre-delivers necessary playback files, so that when playback is requested, all security checks are already complete and the process is transparent to the user.
3Reliability
If playback files are distributed separately from the disc, then security against piracy is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements automatic feedback loops where the disc player continuously communicates with the authentication server to verify disc validity and user authorization. Based on this feedback, the system automatically retrieves and installs necessary playback files, creating a seamless experience where security checks occur in the background without requiring user action.

AI summary
In one embodiment, a method of controlling distribution of content can include: sending authentication instructions from a server to a disc player having a disc inserted therein, where the disc includes media content without a plurality of files that are required by the disc player for playback of the media content; determining if the disc in the disc player is valid by comparing information received from the disc player against information stored in a database; receiving viewer verification information from the disc player to determine if the viewer is authorized to view the playback of the media content on the disc; sending an error indication if the disc is not valid and/or the viewer is not authorized; and sending the plurality of files that are required for the playback of the media content from the server to the disc player if the viewer is authorized and the disc is valid.
