Digital Media Content Segmentation for Secure DRM Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital rights management (DRM) systems increase system complexity, processing time, and costs while aiming to limit access to digital content, necessitating a more efficient and secure method for transmitting, storing, and making digital media content available.
Innovation Solution
A method and apparatus that deconstructs digital content files into control and payload information portions, storing them separately with packing data referencing each other's location, allowing secure and efficient playback and storage on user devices, even in inaccessible memory areas, and reconstituting the content upon access permission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional DRM encryption methods are used to limit access to digital content, then content security is improved, but system complexity increases
Solution Approach 1:
The content file is divided into separate control information and payload information portions, stored in different locations. This segmentation allows the system to manage access control separately from content delivery, reducing overall system complexity while maintaining security through distributed storage and selective reconstitution.
2Reliability
If traditional DRM encryption methods are used to limit access to digital content, then content security is improved, but processing time increases
Solution Approach 1:
Control information and payload information are pre-separated and stored in ready-to-use locations. When playback is requested, the system quickly retrieves and reconstitutes the content without requiring time-consuming decryption operations, as the separation itself enables efficient access control and content delivery.
3Reliability
If traditional DRM encryption methods are used to limit access to digital content, then content security is improved, but implementation costs increase
Solution Approach 1:
The system uses information copying and reconstitution rather than complex encryption/decryption operations. Control information serves as a key to reconstitute payload information into playable content, replacing expensive DRM licensing and processing with simpler data manipulation techniques that reduce implementation costs.
4Reliability
If content is stored in inaccessible memory areas for security, then content protection is improved, but ease of access decreases
Solution Approach 1:
Control information acts as an intermediary between the securely stored payload information and the content player. The control information, which can be accessed easily, contains the necessary data to retrieve and reconstitute the payload information, thus maintaining security while enabling convenient access through a simple mediation process.

AI summary
A digital media content management apparatus and method for securely storing a content file on a computer readable medium and playing the content file from the computer readable medium is disclosed. The content file comprises control information readable by a content player and payload information including content data. The content file is deconstructed into at least one control information portion and at least one payload information portion being undetectable to a content player of a user device. The control information portion and the payload information portion are separately stored, and at least one of the portions is associated with packing data, and the packing data associated with at least one of the portions comprises a reference to the location of the other portion.
