Digital Media Licensing System for Authorized Secondary Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ease of reproduction and distribution of digital media content poses challenges in ensuring authorized secondary distribution while preventing unauthorized overuse and redistribution, as digital media can be copied and stored on personal computers, making it difficult to verify ownership transfer and control access rights.
Innovation Solution
Implementing a system that allows genuine purchasers to allocate access rights through secondary licenses, enabling them to share digital media content by assigning temporary or permanent access rights, which can be limited by device type, format, or duration, ensuring authorized sharing while protecting creators' interests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital media content is made easily reproducible and distributable, then ease of sharing content with others is improved, but unauthorized redistribution and overuse increases
Solution Approach 1:
The patent segments access rights by creating distinct license types (personal use license, secondary user license, commercial license) that divide the monolithic copyright into manageable, enforceable portions. Each license type grants specific permissions and restrictions, allowing the system to enable sharing while maintaining control over different usage scenarios.
Solution Approach 2:
The patent introduces a licensing server as an intermediary between content owners and users. This mediator verifies ownership, issues appropriate licenses, and enforces access controls. The licensing server acts as a trusted third party that enables legitimate sharing while preventing unauthorized redistribution through automated license validation and revocation mechanisms.
2Ease of operation
If digital media content can be copied and stored on personal computers, then accessibility and convenience are improved, but verification of ownership transfer becomes difficult
Solution Approach 1:
The patent implements feedback mechanisms where the licensing server continuously monitors and validates license usage. When content is accessed, the system verifies the user's license status, reports usage back to the licensing server, and can revoke access if unauthorized copying or redistribution is detected. This creates a closed-loop system that provides real-time verification of ownership and usage rights.
Solution Approach 2:
The patent uses cryptographic copying mechanisms where license information is embedded within or alongside the digital content. This embedded metadata contains ownership verification data that travels with the content, allowing the system to verify legitimate copies while identifying unauthorized reproductions. The license data acts as a digital watermark or signature that authenticates ownership transfer.
3Adaptability or versatility
If access rights are transferred to secondary users, then sharing and distribution are improved, but control over usage rights is reduced
Solution Approach 1:
The patent implements dynamic license management where access rights are not static but can be modified, suspended, or revoked based on usage conditions. The licensing server can adjust license parameters in real-time, such as limiting the number of devices, geographic location, time periods, or specific content portions. This dynamic control allows the system to enable sharing while maintaining flexible, enforceable usage restrictions.
Solution Approach 2:
The patent controls usage rights by changing license parameters rather than creating entirely separate systems. The licensing framework allows modification of key parameters such as license duration, content access scope, device identifiers, and user credentials. By dynamically adjusting these parameters, the system enables versatile sharing arrangements while maintaining centralized control over usage rights through parameter-based restrictions.

AI summary
There is provided a method and system for allocating an entitlement to digital media content. In one implementation, the system includes a media server accessible over a communications network and configured to utilize a processor to issue the entitlement including a transferable authorization to access the digital media content to a first user, and to store an entitlement record identified with the first user and authorizing access to the digital media content by the first user in a memory of the media server. The media server is further configured to receive a communication including a data corresponding to the transferable authorization to access the digital media content from a second user and to update the entitlement record to authorize access to the digital media content by the second user.
