Multi-Level Authorization Framework for DRM Media Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to support the access and playback of a comprehensive set of media files with various digital rights management (DRM) types, such as streaming media files, tethered downloads, and purchased downloads, across computing devices in a network environment.
Innovation Solution
A method and user interface that allows access and playback of media files with differing DRM rights by requesting and receiving media file identifiers, applying authorization rules based on user levels, and enabling sharing of media collections among networked devices, allowing streaming or tethered downloads based on subscription and authorization levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM protection is implemented for media files, then media file security and rights management are improved, but system complexity and access restrictions increase
Solution Approach 1:
The patent segments DRM protection into multiple authorization levels (first level and second level authorization) that can be independently applied to different media files. This allows the system to manage complex DRM requirements by breaking them down into manageable authorization tiers, where each tier has specific rights and access permissions.
Solution Approach 2:
The patent creates a universal authorization framework that handles multiple types of media files (streaming, tethered downloads, purchased downloads) with a single multi-level authorization system. This universal approach reduces overall system complexity by providing a standardized method for managing diverse DRM requirements across different file types and access scenarios.
2Reliability
If multi-level authorization is implemented for media access, then rights management control is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service mechanisms where the authorization system automatically determines access rights based on pre-configured authorization levels. When a user requests access to media files, the system automatically evaluates the user's authorization level and grants or denies access without requiring manual intervention, thus maintaining ease of operation while enforcing strict rights management control.
Solution Approach 2:
The patent applies preliminary action by pre-configuring authorization levels and rights before users access media files. The system establishes first level and second level authorization frameworks in advance, so that when access requests occur, the evaluation and decision-making processes are already prepared, reducing operational complexity for users.
3Adaptability or versatility
If comprehensive media file access is enabled across network devices, then adaptability is improved, but authorization management complexity increases
Solution Approach 1:
The patent adds a new dimension to authorization management by introducing hierarchical authorization levels (first level and second level) that operate across the network dimension. This multi-dimensional approach allows comprehensive media file access across network devices while managing complexity through structured authorization tiers, where each level handles specific aspects of access control.
Solution Approach 2:
The patent introduces an intermediary authorization framework that mediates between media files with different DRM types and network devices seeking access. This intermediary system translates diverse authorization requirements into a unified multi-level framework, enabling comprehensive access while reducing management complexity through standardized mediation processes.
Data Source
AI summary
A system that provides for the accessing and playing of media files having differing associated rights such as non-DRM media files, purchased and downloaded media files, subscription download files such as tethered downloads, and subscription streamed DRM files. The system also provides a method and user interface for sharing a media collection among computing devices in communication via a network. The system allows access and playback, from each computing device on a network, of all media files in a media collection, regardless of their associated rights.
