Web-Based Media Asset Sharing With Digital Rights Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sharing of media content assets over networks raises copyright concerns as existing methods do not effectively manage digital rights, leading to potential unauthorized access and distribution.
Innovation Solution
A web-based service that manages digital rights metadata for users, enabling controlled sharing of media content assets by verifying licenses and authorizations through a user database and license tokens, ensuring compliance with copyright protections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users share media content assets through traditional methods (FTP, email, peer-to-peer), then ease of sharing is improved, but copyright protection deteriorates
Solution Approach 1:
The patent introduces a web server as an intermediary between content owners and sharing users. The web server stores media content assets and manages digital rights metadata, acting as a trusted mediator that enables sharing while maintaining copyright protection. Users request access through the web server rather than directly exchanging files, allowing the system to verify licenses and control distribution.
Solution Approach 2:
The system implements feedback mechanisms where the web server continuously verifies user licenses and sharing permissions against stored digital rights metadata. Before allowing access to shared content, the system checks whether the sharing user has proper authorization, creating a feedback loop that prevents unauthorized distribution while enabling legitimate sharing.
2Adaptability or versatility
If users store media content assets locally for sharing, then sharing capability is improved, but device complexity and storage requirements worsen
Solution Approach 1:
The patent merges the storage function with the web server infrastructure rather than requiring separate local storage on user devices. Multiple users can access and share the same media content assets stored centrally on the web server, eliminating the need for each user to maintain local copies. This combining of storage resources reduces individual device complexity while maintaining sharing capability.
3Reliability
If digital rights metadata is implemented for copyright protection, then copyright integrity is improved, but system complexity worsens
Solution Approach 1:
The web server acts as an intermediary that manages the complexity of digital rights metadata storage and verification. Rather than requiring complex metadata management on user devices, the web server centralizes this functionality, storing and processing digital rights metadata while presenting a simplified interface to users for content sharing.
Data Source
AI summary
In one embodiment, a method comprises receiving a request for access to a media content asset from a first user of a web-based service, the request specifying a second user that has provided access to the media content asset; retrieving, from a user database, a user entry describing attributes associated with the second user; determining whether the user entry includes digital rights metadata for determining whether the second user is licensed to share at least a portion of the media content asset; and selectively providing the first user with access to at least the portion of the media content asset based on determining from the digital rights metadata that the media content asset is licensed to the second user, and determining that the first user is authorized by the second user to access the media content asset.
